Recommendations for choosing a gearbox based on the gear ratio

There is no answer that unambiguously removes all doubts regarding the choice of KAMAZ gearbox.
Any device model has its advantages and disadvantages. The designers of the Kama Automobile Plant, who create the famous trucks, select a modification of the gearbox with a certain gear ratio, based on the specified operating conditions. For example, there are obvious differences in the methods of using the KAMAZ 5410, 65116, 54115 highway tractor and the KAMAZ 55111, 65115 quarry tractor in terms of speed limits.

Therefore, cars that travel a significant part of the working time at low speeds are equipped with devices that transmit power by rotation, with an increased gear ratio of 7.22 (50/12) or 6.53 (49/13). And cars whose operation involves mainly driving on good roads are equipped with mechanisms with a reduced gear ratio of 4.98 (46/16) and others.

In any case, the factory configuration of trucks with gearboxes is not a death sentence. If necessary, installed devices on any machine can be easily changed to mechanisms with a different gear ratio. For example, truck tractors 5410 and 65116 can be used as dump trucks with a tipper semi-trailer, or vice versa, dump trucks 55111 and 65115 can operate over long distances and spend most of their time on the highway.

Marking of KAMAZ gearboxes

Each gearbox has an information window that serves to display the following data:

· serial number;

· date of manufacture;

· the value of the gear ratio.

In addition, the gear ratio parameter is additionally encrypted into a combination of characters from the KAMAZ catalog number, which is not found on the gearbox housing.

The series number on the body of the device that transmits power by rotation looks like a set of numbers reflecting the production sequence of the product. For example - 111244. The gear ratio parameter is written without the dividing point 653.

Modifications of KAMAZ gearbox flanges

Models of truck gearboxes differ in the geometry of the cardan flanges, designed to secure the gearbox to the cardan of the vehicle. Early gear housing designs were produced with square flanges. Now gearboxes are equipped with round-shaped connecting elements, produced according to Euro standards, with spline cutting on the connecting plane and axle gears.

Round splined holes are used to secure the gearbox to the driveshaft using bolts.

Axle shaft gears are a block of gears into which the axle shafts are inserted directly, transmitting torque to the wheels of the vehicle. 16-spline axle gears were used on older models 5320, 5511, 55102, 5410, 53212.

New truck models are equipped with axle gears with two dozen splines, or their variations with additional protrusions on the shaft under the ICD (inter-wheel locking).

MKB (inter-wheel locking) of the KAMAZ gearbox

The locking system is located on the cross-axle differential. The ICD, when turned on, does not allow one wheel to spin faster than its pair, evenly distributing the load on both rollers. This feature prevents the car from slipping when driving on a slippery road, or allows you to easily get out of the mud.

MOD (center differential) of the KAMAZ gearbox

The piglet or center differential is mounted on the middle axle gearbox. It is used to turn the middle axle of a car on and off, for example, when driving on a highway to save fuel. And when the car requires increased cross-country ability, the middle axle is easily activated through the same system.

Rear axle gearbox KamAZ-43118 53205-2402011-10(-20,-30,-40) with locking 48.49 (47.50) teeth

Description and features:

The KAMAZ gearbox is one of the most important components of the transmission, transmitting torque from the driveshaft to the wheelset.
The transmission is subjected to heavy loads while the vehicle is moving and is often prone to breakdowns. This gearbox can only be used on trucks equipped with one drive axle.

KamAZ rear axle
Standard version The KamAZ rear axle is a welded steel beam of complex shape, at the ends of which there are flanges for mounting brake calipers, and in the central part there is a flange for attaching the gearbox housing.

In addition to the structural part, the rear axle also includes elements responsible for transmitting torque.
First of all, this is the KamAZ rear axle gearbox, which consists of a cross-axle differential, a main gear, and an axle shaft. The presence of a differential ensures uniform distribution of torque, which makes the operation of the axle more efficient and reduces the level of wear of individual parts of the wheel drive. Tips for installing the KamAZ gearbox
1. Before installing the gearbox, you must thoroughly clean the axle housing, the so-called “stocking”. 2. Make sure that the axle crankcase breather is working properly to avoid squeezing out the seals. 3. When replacing the gearbox, be sure to change the oil to new oil from recommended manufacturers. 4. It is necessary to use a strictly original paranitic gasket between the stocking and the gearbox housing.

The last two digits indicate the number of teeth:

10 — 49/13 20 — 50/12 30 — 48/14 40 — 47/15 60 — 46/16

Typical breakdowns:
The middle axle of the truck vibrates.

If there is slight vibration, it may be a bearing issue.
It is necessary to check and replace the bearings of both the center differential flange and the rear axle flange. The rear axle of the truck refuses to work.
The most common cause of such a defect is failure of the rear gearbox.
But even if the differential fails, the rear axle may also not work. The appearance of cracks on the KamAZ bridge.
The reason for this defect is large overloads.
A crack in the bridge can also occur due to impacts on the crankcase. In cases of serious crankcase defects, it is better to replace it. The rear axle of the truck howls.
Most likely, the bearings and gears of the gearbox are worn out and must be replaced.
