What happened to the chassis of the Shantui SD16 bulldozer

The Chinese bulldozer Shantui SD-16 is very similar in appearance to the Chelyabinsk tractor T-170 (B-10). In addition, the Shantui bulldozer is comparatively cheaper than similar equipment from Caterpillar and Komatsu. And let’s also add that the Shantui bulldozer is structurally developed based on Komatsu technologies. For example, the running systems of many similar Komatsu and Shantui bulldozers are identical.

According to reviews, the Shantui bulldozer is quite reliable in operation. What “breaks” on this car is most often the chassis system and engine components. Shantui bulldozers are equipped with Shanghai and Weichai engines, developed under licenses from Japanese and American companies. In some cases, it is more economical to buy a Shantui bulldozer than, for example, a ChTZ or CHETRA bulldozer. In recent years, the Chinese Shantui bulldozer has been actively ousting domestic equipment from the market. And only the rise in the dollar exchange rate and the introduction of duties on the import of equipment by the Russian state stopped this expansion.

If your fleet already has Shantui bulldozers, then you probably know its strengths and weaknesses better than anyone and buy spare parts for its repair. But, of course, since the Shantui bulldozer is equipment from a foreign manufacturer, there are always questions in the selection and purchase of spare parts. In this note, we will try to answer one of these questions, namely, share our experience of how to choose tracks for a Shantui SD-16 bulldozer at minimal cost.

Features of the running system of Shantui bulldozers

There are currently more than 20 types of Shantui bulldozers produced in China. In Russia, the most popular modifications of bulldozers are Shantui SD-16, SD-22, SD-32. Each modification of the Shantui bulldozer is equipped with tracks with a certain shoe width, number of track chain links and link pitch.

Shantui bulldozers are available in track widths from 1450 to 2260 mm. Shantui tracks also come with shoe widths from 460 to 1100 mm, depending on the modification of the machine. Shantui tracks also have a run-up in the pitch of the track chain link from 154.25 to 260 mm.

But most often, the pitch of the track chain link is 203 mm. This means that for Shantui SD-16 bulldozers, which have tracks with a link pitch of 203 mm, you can order analogues from Russian manufacturers at lower prices. The number of links (shoes) on the Shantui SD-16 track can be from 37 to 42. The width of the shoe varies from 510 to 910 mm. Different profiles of track shoes are used, including triangular ones.

Various modifications of Shantui SD-16 tracks are used in rocky terrain, coal mines, swamps, landfills and deserts.

Among the main modifications of the Shantui SD-16 bulldozers, we note the SD-16C (coal version), SD-16F (modification with forest protection, complemented by a flat shoe with a flange), SD-16L (swamp shoe with a triangular shoe) and SD-16R (modification with a wide triangular shoe). shoe), as well as the basic model SD-16 (37-link track with a shoe width of 510 mm).

What is the main difference between the running system of the Shantui bulldozer? The chassis of the Shantui bulldozer is a floating type design. Elastic buffers are used to connect the bulldozer frame and road wheels. This reduces wear on chassis parts and increases the effort on attachments.

How to choose the right Shantui caterpillar?

One of the main problems when selecting Shantui SD-16 tracks is that often the coordinates of the running tracks of the track chain links of one manufacturer may not coincide with the dimensions of the running tracks of the rollers and idler wheels of another manufacturer. That is, simply put, the caterpillar does not “stand” on the rollers and wheels. Or, when purchasing shoes and track chains from different suppliers, it may also turn out that the mounting coordinates of the shoes do not match the mounting coordinates of the track chains. In this case, you will not be able to assemble the caterpillar. Why is this happening?

This is due to the fact that in China, several dozen enterprises are engaged in the production of parts for running systems for Shantui bulldozers. In addition, the Cheboksary Aggregate Plant produces tracks, track chains, rollers and wheels of its own design, which differs in coordinates and dimensions from similar Chinese products. This is done so that you buy the entire Shantui bulldozer running system, and not its individual components or components. All this brings confusion to the Shantui SD-16 spare parts market.

To select a Shantui track, first of all, you need to know the modification of the Shantui SD-16 bulldozer, namely: track width, link pitch, shoe width and the number of links in the track chain. If you do not know all of the above parameters, then name the modification of the Shantui bulldozer, and specialists will select the necessary caterpillar for you. But in this case, there will be a risk that when installed on the bulldozer, the parts of the running system will not match each other in size. What to do?

When ordering parts for the running systems of Shantui bulldozers, be sure to specify the coordinates of the shoes, the dimensions of the roller treads and draw up a parts measurement card. For instructions on how to correctly measure the track shoe and track chain of a Shantui SD-16 bulldozer, read here and here.

Also pay attention to the table of interchangeability of undercarriage systems of foreign-made bulldozers of traction class 10, which will help you navigate the types of Shantui SD-16 tracks.

Our technical specialists recommend that when ordering a Shantui SD-16 track, you begin by drawing up a parts measurement card. In this case, you will reduce the risks of incorrectly selecting a shoe, track chain or bulldozer track to zero.

Another important point faced when purchasing Shantui tracks is the choice of manufacturer. We will talk about this in the next paragraph of our article “How to choose a Shantui caterpillar?”

Who makes Shantui SD-16 tracks?

Today there are several dozen enterprises on the market that produce Shantui SD-16 tracks. More than 90% of Shantui tracks are manufactured in China, which is logical, since the leading factories for assembling Shantui bulldozers are also located there. There are also tracks from Russian and Korean manufacturers on the market.

Chinese Shantui caterpillars

There is serious competition within China among Shantui SD-16 track manufacturers. Shantui tracks can be purchased both factory-made and so-called “cooperative”. Hence, as you understand, there are different levels of quality and cost.

Not everything Chinese is so bad. If the Shantui SD-16 tracks are factory-made, then you can be sure that they will exhaust their service life. If the Shantui tracks are assembled in a cooperative, then no one can guarantee that they will not fly apart at the first serious load.

What should a buyer do? How to buy high-quality Chinese Shantui SD-16 tracks? First of all, make a trial purchase of Shantui tracks. Be sure to check all geometric dimensions for compliance with the standards, submit part of the track for metallographic analysis, and so on. That is, fully study what and how the Shantui SD-16 tracks are made of.

Even if after your first purchases you are satisfied with the quality of Shantui tracks, then do a thorough incoming inspection of the geometric dimensions when accepting each batch of products, and periodically check the chemical composition of the metal. If you do not have the financial ability to check the quality of the metal in the laboratory, then at least measure the geometric parameters of the Shantui SD-16 track. If the enterprise does not “maintain” the geometric dimensions of the parts, then what can we say about the quality of the metal.

• The operating parameters of the device do not change in any, even difficult operating conditions.
• It can work in high mountains (up to 3500 m above sea level), in hot and cold climates.

All this, together with a durable power frame, made the model very popular. The parts, components, and mechanisms that make up the bulldozer comply with international standards.

Table No. 1. Technical characteristics

Engine, fuel consumption

Under the hood of the tracked “giant” there is an in-line six-cylinder engine manufactured by Cummins.

• This is a diesel engine with direct fuel injection and a mechanical dosing system. The power plant is cooled by liquid with forced circulation.
• The generation of increased torque is ensured by turbocharging with an intermediate intercooler.

Thanks to this pair, it became possible to operate the machine in the highlands.

• rated speed - 2000 rpm;
• cylinder volume - 14 l;
• torque (crankshaft speed) - 1440 Nm (1400 rpm);
• average fuel consumption - 245 g/kW hour (180 g/hp hour);
• cylinder diameter/piston stroke, mm - 140/152.

The engine is equipped with a twenty-four volt 11 kW starter and a generator producing a current of 30 A at a voltage of 28 volts.

Transmission, chassis

The power transmission is made according to an already established layout. The transmission includes:

• a torque converter for transmitting torque from the engine, represented by a three-element single-phase design;
• planetary gearbox, where gear shifting is carried out by a servo drive, and lubrication of heavily loaded components occurs forcibly;
• main drive, represented by a bevel gear with circular teeth;
• final drives made in the form of a two-stage cylindrical gear drive;
• rotation clutches with band brakes, which are a multi-disc mechanism of permanently closed action.

Drive sprockets are attached to the output shafts of the final drives. They engage with the track links, causing them to move. The tracks themselves consist of 41 shoes each. The blades are supported by 9 support rollers.

• Two of them are located on top, they support the idle branch.
• The remaining 7 are installed below, they take the weight of the bulldozer.

The track is tensioned by a idler wheel located in the front of the chassis.

Hydraulics

The bulldozer’s hydraulic system is equipped according to a scheme already familiar to Shantui. There are 2 circuits in total. One is used to activate the internal mechanisms, the second is needed to power the actuating hydraulic cylinders of the blade and ripper.

• The working fluid is pumped by a gear pump.
• It produces 355 liters of oil at an engine speed of 1750 rpm.
• The pressure limited by the bypass valve is 14 MPa.
• The hydraulic system is controlled by a multi-way valve.

A total of 7 actuator cylinders are installed on the bulldozer: 3 regulate the position of the blade, 4 regulate the ripper.

Dimensions

Shantui SD32 has the usual dimensions and weight for its class. But, even without surpassing its competitors in these parameters, the machine copes well with the tasks assigned to it.

Workplace

The bulldozer cabin was made in an original shape: in the form of a hexagonal prism. According to the manufacturer, this design improves visibility of work areas, which makes it easier to operate the equipment. By special order, the cabin can be equipped with a ROPS system, which protects the operator in the event of a machine rollover.

The machine is equipped with an electronic centralized system for monitoring the condition of the main components. If a failure is detected, the operator will receive an information message from the system displayed on the control module display screen.

The operator's workplace has a minimum of controls, which makes it easier to operate the equipment.

• All of them are grouped in optimal accessibility, which reduces the operator’s muscle fatigue that occurs during prolonged work.
• The designers also took care of operator comfort. A comfortable seat with the ability to adjust in 3 planes is installed in the cabin.
• The workplace is equipped with a productive ventilation system.

Without relying heavily on the tightness of the seals, the developers simply created excess pressure in the cabin, which prevents dust or harmful substances from getting inside. Thanks to this, the machine can be used on sites with dusty bulk materials, or on household waste landfills.

Parameters of dumps, ripper

In the basic version, the machine will be equipped with a straight bulldozer blade and a single-tooth ripper without the ability to adjust the angle of attack. Additionally, Shantui offers rotating, spherical blades. In addition, it is possible to attach a three-post ripper. Here are the main characteristics of each of them.

Table No. 3. Parameters of working tools

Equipment

Shantui SD32 is available in several versions. Depending on the conditions in which you plan to use the device, it will be additionally equipped with the necessary equipment. All models will have a heater and air conditioning installed as an option.

The basic package does not include a ROPS operator protection system.

To start the engine in cold regions, the power unit will be equipped with a fuel heater manufactured by Webasto.

Transmission

It includes:

• final drive, which is represented by a gearbox having two stages and a cylindrical shape, as well as a lubrication system;
• hydraulically powered pedal to control the brake;
• rotation clutch. It is placed in an oil bath and is permanently closed. In addition, it is dependent on the braking system;
• bevel gear, lubricated by splash lubrication. This transmission is the main, spiral-toothed one;
• planetary gear, the lubrication of which is forced, and switching is done using a servo drive;
• The torque converter assumes the presence of three elements, is single-phase and has one stage.

All elements are interconnected and have their own structural features. The gearbox allows the Shantui SD16 bulldozer to move forward and backward at three speeds. Depending on the selected gear, the speed of the machine will be different.

Design and operating features

Shantui SD16 has a modular design that allows for quick inspection and repair. In the basic version, the bulldozer is equipped with a balancer suspension and a caterpillar track with large and wide links that ensure the stability of the equipment. The tracks are mounted on 2 suspension and 6 road wheels.

The model's transmission is represented by the following elements:

• planetary gearbox with shift servo and forced lubrication mechanism. The gearbox has 6 speeds (3 forward and 3 reverse);
• a permanently closed multi-plate clutch, which is located in an oil bath. The clutch is connected to the brake element of the steering clutch;
• 3-element single-stage single-phase torque converter;
• floating brake of the rotation clutch, controlled by a pedal with hydraulic booster;
• bevel-type main spiral gear transmission with a bubbling lubrication mechanism (splashing) and a single-stage gearbox;
• final drive, made in the form of a bubble lubrication mechanism and a cylindrical gearbox.

The Shantui SD16 hydraulic system operates via a gear pump with a capacity of 335.5 l/min. Control is carried out through a special hydraulic control valve. The pump operates on the basis of 2 cylinders belonging to a 2-way hydraulic system with a diameter of 110 mm. The maximum pressure in the system is 14 MPa.

A hexagonal cab is installed on the bulldozer. This solution is optimal for equipment in this segment, as it provides the operator with maximum visibility and allows him to see an expanded panorama in any situation. The rigid frame makes work safe.

The cabin lining uses modern insulating materials that reduce vibration and noise, resulting in fewer extraneous factors affecting operator fatigue. The interior is equipped with factory heater and air conditioning. They maintain the required level of humidity and temperature regardless of the climatic conditions in which the machine is located.

The operator's seat can be adjusted in several directions (brand – Grammer). The close proximity of the main control devices to the driver and their ergonomic location allow you to work as productively as possible. The cabin itself has air suspension.

Shantui SD16 can be equipped with a wide range of additional equipment, including several types of blades, a 3-shank ripper and a special single-shank ripper that can withstand increased loads and operate at sub-zero temperatures. This configuration allows you to perform various tasks on a hard surface.

The bulldozer is characterized by ease of maintenance. The main units and components of the machine have a simple design; they can be inspected and repaired in the field. Spare parts for equipment are freely available in most specialized centers. However, some items must be ordered from China, which may slow down the repair process. The bulldozer itself is highly reliable and lasts for many years until a major overhaul is carried out.

Operator's cabin

To increase the viewing angle and accuracy of the operator's work, the cabin is made in a new geometric hexagon shape. The developers are confident that this design is rational for the Shantui SD16 heavy equipment. The frame is made rigid, which has a positive effect on driver safety.

To increase the concentration of the person operating the equipment, the entire cabin upholstery is made of sound and vibration insulating material. The standard equipment of the Chinese Shantui bulldozer includes air conditioning and heater. This guarantees normal operation of the operator regardless of the surrounding natural conditions.

The Grammer chair can be adjusted and placed in a comfortable position, all devices are located very conveniently and within reach. Hydraulics allow you to apply less effort to switch levers. The system itself is equipped with new cylinders and water seals.

In general, the entire cabin is made ergonomically; the increased level of glazing (360-degree viewing angle) also has a beneficial effect on the general condition of the driver, reducing his level of fatigue.

Chassis

Shantui SD16 track

The basis is a caterpillar track, the stability of which when driving is guaranteed by a suspension with a balance. The track is located on six rollers, plus two on each side are designed to support it. The suspension is modular to reduce time lost on repairs or replacement of components. The width of the standard assembly belt is 0.51 m, its pitch is 0.203 m. Depending on the conditions of the working site, the tracks can be replaced with narrower or wider ones. To increase traction with the base, tracks with lugs are used. If you choose the right type of tracks, the Shantui 16 vehicle can have very high maneuverability. In addition, the angle of the working platform can be 30 degrees.

Non-stop operation of the engine is guaranteed due to its double protection. Because of these qualities, the engine is considered very reliable. The gearbox allows you to change them without having to press the clutch. This reduces time and makes operating the equipment easy and simple. The ability to drive in reverse also has a beneficial effect on these parameters.

MAINTENANCE AND REPAIR OF BULLDOZER SD16, SD16E, SD16L, SD16S

6.1 Precautions for maintenance behavior

Proper lubrication and maintenance are important to extend the life of the machine, ensure ergonomic and mechanical safety, and increase operating efficiency and economy.

People operating the machine and performing its maintenance, in addition to knowing the “Safety Recommendations,” must comply with the following rules:

a) Mechanics must have a good knowledge of the machine structure, technical characteristics, assembly and dismantling procedures, technical requirements and safety precautions. Never act blindly.

b) Always contact the manufacturer when carrying out complex maintenance or if the machine is unsuitable for service.

c) Always carry out maintenance before starting to operate the machine and after finishing work. During maintenance, park the car on a hard, flat surface. Lower the blade and set all control levers to the “lock” position.

d) If maintenance is carried out with the engine running, 2 people must be present: one must sit in the driver’s compartment, and the other must carry out maintenance. In this case, it is prohibited to touch any moving parts of the machine.

e) Wash the car thoroughly. Be especially careful when cleaning filler caps, grease nipples and the area around the level indicator rods. Make sure that dirt and dust do not enter the system.

e) Always remember that the hydraulic oil pipeline is under pressure.

When draining the oil and performing inspection or maintenance, the pressure must first be relieved.

g) The procedure for relieving pressure is as follows: lower the blade and ripper to the ground, stop the engine. Move the control lever 2-3 times to each position, and then slowly unscrew the filler cap.

h) Always use clean oil or grease and ensure clean containers are used. When checking and changing the oil, do it in a dust-free room, avoid getting dirt into the oil.

i) Do not work with electrical equipment wearing wet gloves or in a damp place, as This may cause an electric shock.

j) Before changing the oil, warm it up to a temperature of 30-40°C and then drain it.

k) Be careful when checking and adding coolant, there is a danger that boiling water will splash out of the tank.

l) After replacing the oil, filter element and filter mesh, bleed the air from the circuit.

m) When the filter mesh is in the oil filler neck, there is no need to remove the filter mesh when filling the oil.

o) When checking and opening the gearbox, there is a risk of things being pulled into it. Before removing the cover to check the transmission, remove everything from the pockets. Be especially careful when removing dynamic screws and nuts.

o) Keep oily substances away from fire. Never use a flame instead of a lamp.

p) When removing parts containing o-rings, seals or gaskets, it is necessary to clean the mounting surface and replace the sealing elements with new ones.

Rice. 6-18

a) Remove the bolts, cover and external filter element.

b) Clean the inside of the air cleaner and the cover.

c) Clean and check the filter element, and then replace it.

*It is necessary to replace the filter element that has been cleaned 6 times or has been used for more than one year.

*Replace the sealing washer and wing nut if they are broken.

*If, after installing a cleaned outer filter element, the indicator soon returns to the red area, it is necessary to replace both the outer and inner filter elements, even if the outer element has been cleaned less than 6 times.

*Check and tighten the fastening nuts of the internal filter element.

Replacing the internal filter element

a) First remove the cover and outer filter element, then pull out the inner filter element.

b) Cover the air inlet

c) Clean the inner surface of the air cleaner housing.

d) Install a new internal filter element onto the connecting piece and tighten the nuts.

e) Install the external filter element and cover.

*Do not attempt to install a used internal filter element.

! Do not clean or replace the air cleaner filter elements while the engine is running.

Cleaning the external filter element (Figure 6-19)

Cleaning with compressed air: direct a stream of compressed air (pressure no more than 0.7 MPa) first from the inside of the folds of the element to the outside, and then from the outside to the inside of the folds until the element is completely cleaned.

Other ways to clean the filter element:

Cleaning with tap water: rinse the element with tap water (pressure no more than 0.3 MPa) along the folds from the inside and outside until the element is completely clean.

Cleaning with detergents: Wash the element with warm, mild detergent, then rinse in clean water and dry.

*Cleaning can be accelerated by using compressed air (pressure no more than 0.7 MPa), directing the jet from inside to outside. Do not heat the element!

*Using warm water (approximately 40º) is more effective than washing with soapy water.

*Point a beam of light at the inner surface of the element and check its condition. If small holes or foreign objects are found in the filter housing, it must be replaced.

*Do not use item with damaged folds, gaskets or seal.

*When cleaning the element, do not heat it or expose it to any objects or hit it with anything.

Cleaning the internal parts of the cooling system

Clean the internal parts of the cooling system, replace antifreeze and corrosion protection in accordance with the table below.

*Before changing the water, stop the machine on a level surface.

*Use permanent antifreeze.

If it is not possible to use permanent antifreeze, you must choose antifreeze containing ethylene glycol.

*Replace the corrosion protection cartridge in a timely manner (if any)

*Use clean water (e.g. tap water) to cool the engine.

! Since antifreeze is flammable, it must be kept and handled away from sources of fire.

Antifreeze type	Cleaning internal parts of the cooling system, replacing coolant	Replacing the corrosion protection cartridge
Permanent antifreeze (all-season)	Every year (autumn), or every 2000 operating hours	Every 1000 operating hours, as well as when cleaning internal parts of the cooling system and replacing coolant
Non-permanent antifreeze containing ethylene glycol (winter type)	Every year (in winter), or after the first 2000 operating hours
When antifreeze is not used	Every 6 months (spring, autumn) (draining antifreeze in spring, adding antifreeze in autumn)

When determining the proportion of water and antifreeze, you should focus on the lowest temperature level in the region where the machine is used, as well as on the table below (below 10º is the best option)

The ratio of water and antifreeze in the coolant composition

Minimum ambient temperature (ºС)	-5	-10	-15	-20
Antifreeze volume (L)	14,5	19	22,5	26
Water volume (L)	48,5	44	40,5	37

a) Stop the engine, close the corrosion protection valve (if installed).

b) Slowly unscrew the radiator cap.

! Be careful not to be scalded by the hot water jet.

c) Loosen the drain valve in the bottom of the radiator and unscrew the drain plug on the side wall of the oil radiator. Drain the engine cooling water.

d) Close the drain valve and plug, fill with clean water to the level of the filler pipe. e) Start the engine at high speed, loosen the drain valve and unscrew the drain plug for 20 minutes after draining the water.

*When flushing, monitor the water pressure so that the radiator is full at all times.

f) After washing, drain the water, tighten the drain valve and drain plug. g) When flushing the cooling system, use detergents in accordance with the instructions given in the operating instructions.

h) After washing with detergents, drain the water and close the drain valve. Fill with clean water (tap).

i) Start the engine at high speed, loosen the drain valve and unscrew the drain plug and flush the cooling system until the water coming from the drain valve and drain hole is clear.

j) When the water becomes completely clear, stop the engine and tighten the drain valve and drain plug.

k) Replace the corrosion protection cartridge and open the valve (if there is a corrosion protection).

m) Fill with clean water until it begins to flow out of the filler pipe. m) Start the engine and run it for 5 minutes at low speed and 5 minutes at high speed to bleed air from the cooling system (the radiator inlet must remain open during this operation).

o) Stop the engine and wait approximately 3 minutes. Add water to the required level and screw on the lid.

Lubrication

Introduce grease into the grease fittings according to the following instructions:

a) Brake pedal shaft (5 points).

b) Brake pedal stop shaft (1 point). c) Retarder pedal shaft (1 point).

d) Fuel control pedal shaft (1 point).

Check the functional condition of the electric intake air heater (if installed, see engine instructions).

Check and tighten track bolts.

Check and tighten the connecting link (if installed).

a) First tighten the bolts (tightening torque - 300±30 Nm), then check the tightness of the contact surfaces of the connecting link.

b) After checking, tighten the bolts again by 180º±10º.
