Brands and filling volume

When performing maintenance, you should not be guided by the data in the table of container volumes, because in most cases, the volume of liquid to be filled is less.

Calculation of the volume of lubricating and cooling liquids (cooling fluids) is carried out taking into account the required operating conditions of the units, and the volume of the containers intended for them takes into account heating and thermal expansion during operation, the volume of paths and lines connecting the units and containers, and the method of application of the coolant.

For example, for combined lubrication of engine parts, oil is poured into the engine crankcase. It is supplied under pressure continuously to the rubbing surfaces (crankshaft and camshaft journals, intermediate gear bushings and fuel pump gears), the valve mechanism is lubricated under pulsating pressure, and the remaining parts are lubricated by splashing.

The quantity of refilled materials and their brand must correspond to that specified in the technical manual for the tractor, taking into account the time of year and air temperature.

M-8DM (for operation at temperatures below +5°C) and M-10DM (at temperatures above +5°C) are used as motor oil for diesel engines installed on MTZ tractors.

It is allowed to use oil brands M-10G2K and M-10G2 with similar characteristics. The filling volume into the engine crankcase is 12 liters.

The listed brands of motor oil are also used to lubricate the four-plunger fuel pump and air cleaner. The filling volume for the first is 0.25, for the second - 1.5 liters.

At low temperatures - from -40°C and below - it is allowed to dilute the oil by 15% with diesel fuel to lubricate the fuel pump.

The crankcases of the power transmission mechanisms are fully refilled; for a scheduled replacement, 40 liters of transmission oil of the brands TAp-15V, TSp-10, TSp-15K or TAD-17 are required. The same grades are used for the wheel gear, upper bevel pair, drive support and drive pulley; these mechanisms are also filled in full.

The power transmission also includes a reduction gearbox, made in the same housing with the clutch mechanism. A friction-type dry clutch is installed in a dry compartment of the housing; lubrication in the clutch mechanism is required only for the release bearing; for this purpose, solid oil or LITOL-24 is used. Oil from the reduction gear compartment entering the dry compartment is unacceptable.

The following types of engine oil are used for hydraulic system and power steering components:

Lubrication of bearings of many components - bushings, hinges, hubs, cardan transmission supports and others - is carried out with LITOL-24, grease or LCP-GM grease lubricants. These materials are poured using a special syringe through grease fittings.

Engine

The power unit on the MTZ-1221 tractors is D. 260.2S, equipped with a turbocharger. This six-cylinder engine, whose volume is 7.12 liters, can be filled with both domestic and imported fuels and lubricants. In addition to economical fuel consumption, it also has the advantage that it meets all environmental safety standards. If desired, the Belarus-1221 tractor can be equipped with a Deutz engine with a power of 141 hp. With. and volume 6 l.

Hydraulic system

Any attachment can be used on the MTZ tractor. To control it, the design of modification 1221 has a special hydraulic system. Its advantages include simplicity and ease of maintenance. The oil tank is very large, and the system itself can operate on both domestic and imported oil. If desired, two types of hydraulic systems can be installed on this tractor:

The gearbox is one of the most important components of any vehicle. It is the gearbox that is responsible for changing the direction and speed of movement. For a tractor with its high fuel consumption and significant load on the power plant, the correct choice of program allows not only to reduce fuel consumption, but also helps to extend the service life of components and assemblies.

In order to operate the gearbox in optimal mode, timely identify faults and carry out repairs, it is necessary to present a diagram of the arrangement of individual elements and the principles of operation of the unit.

The device of the MTZ-1221 box

The gearbox is a mechanical 6-speed unit with constant mesh gears. Has 4 forward modes and 2 reverse modes. Supports the ability to switch 4 speeds within each range using special synchronizers. As a result, the gearbox provides 16 front and 8 rear driving modes.

The MTZ tractor gearbox includes the following components:

• control mechanism;
• transmission unit;
• gear block;
• secondary shaft;
• reverse and low gear shaft;
• hydraulic system;
• housing in which the above elements are located.

Gearbox MTZ-1221: shift diagram

In the Belarus tractor, the gearbox control mechanism consists of two components: a gear shift unit with synchronizers and a range switching device. Each of these units has its own separate control lever in the tractor cab.

Accordingly, when the desired speed is turned on, the gear selector lever is first set to the required position, and then the range selection lever.

The diagram for switching gearbox operating modes is shown in the photo located on the website. Roman numerals indicate the positions of the gear lever, and Arabic numerals indicate the positions of the range selection lever.

Malfunctions of the MTZ-1221 gearbox

The tractor gearbox is a reliable, wear-resistant device that can last more than three years in daily use before undergoing initial repairs.

To do this, it is necessary to observe the appropriate operating mode of the unit itself and the elements associated with it. The serviceability of the gearbox is influenced by the following factors:

• sufficient oil level and appropriate pressure;
• timely cleaning of the centrifuge and filter elements;
• compliance with the clutch adjustment mode;
• condition of the front drive axle;
• correct adjustment of the engagement of the rear axle GP (for all-wheel drive models).

Repair of gearbox MTZ-1221

The first stage of repair is dismantling the gearbox, complete disassembly and washing of components and assemblies. Further actions depend on the nature of the breakdown. The most typical malfunctions and causes of their occurrence:

• lack of gear engagement - wear of the components of the upper gearbox cover;
• damage or increased wear of the input shaft gears - low oil pressure or clutch malfunction;
• Damage to the bearings or breakage of the secondary shaft nut – incorrect adjustment of the gearbox engagement.

MTZ-1221 gearbox: switching diagram

For the driver’s convenience, the switching diagram is located near the corresponding lever (see photo on our website).

It must be taken into account that in order to avoid increased wear of gearbox parts, the gears are switched on sequentially. Shifting within the range on the fly is only permissible when driving on a flat road. In off-road conditions, it is recommended to overcome such sections in a pre-selected mode.

Changing the oil in the tractor gearbox

For example, MMZ Engines

High-quality timely maintenance is a guarantee of excellent operation of the MTZ-1025 tractor. The serviceability of the equipment depends on the condition of the transmission and rear axle.

Therefore, when carrying out maintenance, it is necessary to timely change the MTZ oil.

Work order

Changing the MTZ oil of the rear axle is carried out together with changing the fluid in the gearbox.

The tractor components are closely interconnected and have one oil filler neck.

Therefore, before starting the replacement, first warm up the transmission.

When heated, the viscosity of the liquid decreases and drainage becomes easier.

Then the MTZ-1025 tractor is installed on a flat, level area.

Turn off the MTZ engine and lower the attachments.

To avoid spontaneous movement, the tractor is secured using a hand parking brake.

Further:

• The wheels are blocked with wedges.
• Remove the cap from the oil filler neck.
• Unscrew the plugs on the gearbox and rear axle housings.
• The oil must be drained immediately after stopping the engine by gravity flow under pressure. When all the liquid has left the system, the plugs are tightened.

After replacement, run-in the tractor for 2-3 minutes.

Useful tips for changing oil

Do not forget that the liquid is poured to the “P” mark with permissible deviations of no more than 7 mm.

When changing the oil, it is necessary to clean the MTZ-1025 filters. The magnets are also washed.

For the MTZ gearbox and rear driveshaft, domestic and imported oils recommended by the manufacturer are used:

1. M-10G2 GOST 8581-78 (summer version);
2. M-8G2 GOST 8581-78 (winter);
3. SAE 15W-40.

It is allowed to use oil poured into the engine crankcase. When operating the MTZ-1025 tractor, pay attention to extraneous knocks in the transmission. Check the oil level and pressure in the system.

An oil change is combined with seasonal maintenance if no more than 200 hours of MTZ operation remain before maintenance. Drain the liquid yourself or at a service station.

It is recommended to change the MTZ oil every 1000 operating hours of the tractor to avoid malfunctions. And finally. Do not skimp on changing the oil of your tractor systems.

If not replaced regularly, more serious damage may occur over time. You can always find MTZ spare parts in Rostov for the most modern MTZ equipment in our MTZ catalog.
