Transfer case KamAZ 4310: device, purpose, repair

The KamAZ-4310 is distinguished by increased cross-country ability on the roadway. This vehicle is positioned as a reliable machine that can handle the loads well. Freight vehicles began to be produced in the USSR in the early 1980s. It was mainly produced for the needs of the Soviet Army.

The vehicle dimensions are as follows: 7650×3590×2500 mm. Moreover, the weight exceeds 8 tons. Acceleration to 60 km/h occurs in approximately 35 seconds. However, about 30 liters of fuel are consumed per 100 km.

Technical features of KamAZ-4310

KamAZ 4310

The machine has several modifications that differ in power, the presence/absence of a winch, and a berth. The peculiarity of the basic version is that it includes a platform with a voluminous awning and a rear, folding side. More than 25 people can fit in the back of this vehicle. The cabin provides comfort and convenience to the driver when moving.

Characteristics of the power take-off

Appearance of the COM

A power take-off (PTO) is a working mechanism that in most cases is installed on vehicles suitable for cargo transportation. This unit allows you to save on fuel consumption.

The power take-off box on KamAZ-4310 is fixed at the rear end of the box with several bolts. It includes spare parts that cope well with high loads. There are diaphragm pneumatic chambers.

The power take-off has an activation mechanism, which has a housing, a cover, and a rod. Thanks to the presence of an electro-pneumatic valve, air is supplied towards the pneumatic chamber.

It is worth considering the device, purpose of the RK, as well as the principle of operation.

Signs of a transfer case breakdown on a KAMAZ 4310, 43118 vehicle

If there are obvious signs of breakdown, then the RC must be replaced; this should be done in the following cases:

First of all, this is a characteristic knocking noise that occurs due to damage to the teeth on wheels equipped with such teeth, and if the bearing ceases to function due to wear.

Due to the fact that the teeth on the couplings, on the gears and on the gearboxes become unusable, the gears are switched off randomly. The shift fork foot may also be damaged.

If the parts that are in the gearbox are worn out, this leads to the fact that the gears are difficult to engage, the gear shift rods jam, and the differential locks. The power take-off on KAMAZ-4310, 43118 vehicles may also jam.

Possible damage to the RC, for example, chips, cracks. Failure of fastenings and other damage that can be considered mechanical.

How to make repairs

Using the provided hole with a plug, drain the oil from the valve;
Remove the special shields located on the floor of the platform, having first unscrewed the clamp nut;
Separate the driveshaft, which is considered the main one, and the drive shaft;
Disconnect the drive shaft on the front axle from the drive;
Disconnect the drive shaft on the intermediate axle;
Disconnect the driveshaft located on the drive from the power take-off;
Also disconnect the speedometer, that is, the converter plug on the Kamaz-4310, 43118;
There are also wires for indicator lamps, which are responsible for the differential lock and overdrive. Also downward.
On the Republic of Kazakhstan, remove the ground wire from the bracket
The hoses connecting the pneumatic chambers are the same as above: differential, power take-off and both gears, high and low.
Unscrew the nuts on the control valve and remove the bolts to dismantle the control valve.

Transfer case device

It should be noted that there is a transfer case (TC) on the KamAZ-4310. Its constituent parts are shafts, a crankcase, and a gear responsible for overdrive. Also, the gearbox is supplemented with a center differential.

Transfer case diagram

The KamAZ-4310 transfer case diagram clearly shows that the input shaft is mounted on roller bearings. They tolerate combined loads well. The input shaft bearing (front) has a cone shape. This element is located at the front end of the crankcase cover. Gears are designed for long service life.

Thanks to the bearings, the movement of the intermediate shaft is carried out. Gears and satellites are reliable. The RK includes a membrane pneumatic chamber, which activates the center differential lock. This ensures the rotation of all wheels. When driving over rough terrain, the differential is locked.

Thus, a transfer gearbox is typical for vehicles with increased cross-country ability. It ensures the transmission and division of the moment of force. This device includes mechanisms that affect the quality of the trip. Also, it helps out if you are driving on rough terrain. Transfer cases differ in the number of gears.

A power take-off gear 7 is welded to the drive gear 5 of the input shaft. The low gear gear 12 and the high gear gear 25 are mounted on rollers. The differential is of a planetary type with four satellites 15, a sun gear 22 and a main gear 20, the main gear 20 is connected to the rear axle drive shaft 18. The rotational torque of the sun gear is transmitted to the front axle drive shaft 32. When the differential is running (unlocked), constant and uniform traction on all axles is ensured, and additional loads in the transmission are eliminated. Depending on road conditions, the differential can be turned off (locked), and then the drive shafts of the front and rear axles rotate as one unit.

Transfer case problems

The RK on KamAZ helps vehicles overcome road obstacles and improves ride quality. Proper care of the transmission system on the driver's side can extend its life.

Each of the constituent parts of the Republic of Kazakhstan needs timely verification. Repairing differentials is considered expensive from a financial point of view. The main sign that a breakdown of this element has occurred is the appearance of a howling sound when moving at high speed. Motor vehicles are subject to mandatory diagnostics.

What is the cause of vibration? As a rule, this manifestation is a consequence of the fact that the fastening bolts have become loose. Also, it is worth inspecting the drive levers to see if the differential is worn out.

If it is difficult to switch on the speeds, you should check the condition of the rods. If the gear shift drive is deformed, the speeds will operate spontaneously.

If any of the above manifestations occur, disassembly of the transfer case is required. Worn clutch teeth and gears must be replaced. The troubleshooting procedure should be entrusted to specialists working in a specialized service center.

Causes of breakdowns with transfer case

The main reason that there was a problem with the functioning of the KamAZ-4310 transfer case is frequent travel on the roadway at high speeds, which places increased loads on the KamAZ vehicle system. The consequence of this is wear of the seals. When repairing a box, you need to use high-quality components that are covered by a warranty.

Among the signs that the KamAZ-4310 has a breakdown with the transfer case, the following manifestations should be highlighted:

the appearance of a characteristic knock;
gear shifting occurs with difficulty;
the driving dynamics have worsened.

As a rule, knocking noise from the gearbox occurs as a result of damage to the teeth on the wheels when the bearing wears out. You should also check the shift fork. The appearance of extraneous noise from the KamAZ gearbox may be due to the fact that the transfer case has chips or cracks.

Adding oil to the crankcase

TSp-15k

New fuel is added to the crankcase through a special connector closed with a plug. It is possible to control the oil level through the lower hole, supplemented by a magnetic plug. Typically, about 5 liters of fluid are required in the crankcase. It is recommended to use TSp-15k oil.

If there is not enough fuel in the box, it may be difficult to change gears.

Removing the RC from KamAZ-4310

To independently repair the RK, you need to know the structure of this unit. To remove it, it is advisable to drain the liquid in it. Especially for this you need to unscrew the drain plug (you need to substitute an empty container in advance). Next, you should remove the platform floor panels, disconnect the driveshaft, and then proceed to disconnect the plug connection of the speedometer, warning lamps, and pneumatic chamber hoses. Finally, you need to unscrew the nuts and bolts on the valve, after which you should remove the unit.

Thus, KamAZ-4310 is a truck that is equipped with reliable working mechanisms designed for a long working life. The machine is equipped with a transfer case (2 stages) as standard. Also, it should be highlighted the presence of an asymmetrical center differential, complemented by an electro-pneumatic gear shift control drive. The control panel is located on the frame. This box is ready to provide maximum cross-country ability on the roads.
