The KamAZ middle axle gearbox has two transmission stages. Stage 1: - this is the interaction of the driving cone-shaped gear 2402017 with fifteen teeth with the driven cone-shaped gear 5320-2402060 with twenty-six teeth; they are located at right angles to each other, so the engine's traction force rotates 90 degrees on the axle shafts. Stage 2 is the interaction of the drive gear 5320-2402110 and the driven gear 120 of different diameters, a cylindrical type with helical teeth. Depending on the conditions under which the truck is used (lack of roads, asphalt roads, quarry, mountain road, plain), the KamAZ main gear mechanism distinguishes the following types of gear ratios: 1) 7.22: gears with twelve, five-ten teeth 2) 6.53: gears with 13, 49 teeth 3) 5.94: gears with 14, 48 teeth. 4) 5.43: gears with fifteen, forty-seven teeth. The most popular gear ratio among dump truck specialists is 6.53; since it is optimal in the ratio of speed and power of the truck.

Installation and adjustment of gearbox bearings and gears

When installing and adjusting the bearings and gears of the gearbox, install the tapered roller bearings of the drive bevel gear shaft with preload.
The torque required to rotate the drive gear shaft in the bearings should be 0.78... 1.57 N.m (0.08... 0.16 kgf.m). Measure the torque while rotating the flange continuously in one direction after at least five full rotations of the shaft. The bearings must be lubricated. When checking the rotation torque of the rear axle drive gear, the bearing housing cover must be moved towards the flange so that the centering protrusion of the cover comes out of the bearing housing seat and the oil seal does not resist the rotation of the gear. Adjust the bearings of the drive bevel gear by selecting shims from the kit supplied as spare parts.

Install two washers between the inner ring of the front bearing and the spacer sleeve. After the final adjustment of the bearings, tighten the nut securing the bearings of the drive gear of the rear axle (tightening torque 235... 353 N.m (24... 36 kgf.m) and pin it. At the intermediate axle gearbox, tighten the nut securing the bearings with a torque of 235 N.m (24 kgf. m), place the bearing washer and tighten the nut until the hole in the bearing washer aligns with the locking pin of the nut. Then place the lock washer, aligning its protrusion with one of the holes in the bearing washer, and tighten the lock nut with a torque of 235... 353 N.m (24... 36 kgf .m), bend the edge of the lock washer onto the edge of the lock nut. When tightening the nuts, turn the drive gear so that the bearing rollers take the correct position between the conical surfaces.

After assembling the drive gear, measure dimension E (see Fig. 188, 192), since it will be necessary when adjusting the engagement of the bevel gears.

The drive and driven bevel gears of the gearbox are selected at the factory into sets according to the contact patch and the lateral clearance in the mesh, ground in and branded with the serial number of the set. In addition, at the rear end of the drive bevel gear, the deviation value (correction in hundredths of mm) from the theoretical installation size of 81 mm is applied with an electrograph (Fig. 194). The “+” sign corresponds to the distance of the drive gear from the driven axis, the “-” sign to its approach.

When the car is running, the gears are worn in one another. Therefore, if it is necessary to replace gears, replace both gears as a set. Newly installed bevel gears must have the same set serial number.

Rice. 194. Zero position and shift direction of the drive bevel gear

When installing new bevel gears of the gearbox, adjust them according to the contact patch and the lateral clearance in the mesh (Table 33), which should be 0.20... 0.35 mm.

Table 33. Adjusting the gearing of the gearbox bevel gears

The contact patch on both sides of the driven bevel gear tooth should have a length equal to approximately 1/2 ... 2/3 of the tooth length on the forward side, 1/2 ... 3/4 of the tooth length on the reverse side. The minimum width of the contact patch in the middle part should be equal to 1/2 of the active tooth height. The contact should be located closer to the inside of the tooth, but should not extend to its edge. The contact patch extending to the edge of the outer (wide) part is also unacceptable. On the drive gear teeth, the contact patch may reach the top edge. The contact patch is obtained by rotating the drive gear in both directions while simultaneously manually braking the driven gear.

When installing new bevel gears into the gearbox, determine the thickness of the shim pack installed between the drive bevel gear bearing housing flange and the gearbox housing. The thickness of the shim package is determined by the formula:

S = (81 ± correction) + E - B,

where E is the actual size from the end of the drive gear to the flange of the cup (see Fig. 188, 192); B is the actual size of the gearbox from the front end to the axis of the driven bevel gear (see Fig. 186, 190). Assemble the adjusting gasket package from the number of gaskets indicated in the table. 34.

Table 34. Thickness of shims

Be sure to install at least 2 gaskets with a thickness of 0.05 mm under the flange of the glass. and 0.1 mm thick, at least 2 pcs. Select the rest as needed. Thin shims should be placed on both sides of the shim set to obtain a sealed joint.

Tighten the fastening bolts of the intermediate axle drive bevel gear cup to a torque of 98.1... 122.6 N.m (10... 12.5 kgf.m), the rear axle - to a torque of 58.9... 88.3 N.m (6... 9 kgf.m). When finally installed in the crankcase, the drive gear should rotate smoothly, without jamming.

The spur gear shaft rotates in one roller and two tapered bearings, which are mounted with preload.

Adjust the bearings by selecting shims from the kit supplied as spare parts. Install two washers between the inner rings of tapered roller bearings. The torque required to rotate the driven bevel gear after adjustment should be 0.98 ... 3.43 N.m (0.1 ... 0.35 kgf.m). Measure the torque during continuous rotation in one direction after at least five full revolutions of the shaft. The bearings must be lubricated.

Install the driven bevel gear after installing the drive bevel gear. Fully tighten the bolts securing the covers and cup, bearings of the drive bevel gear.

Before installing the driven bevel gear assembly, remove the outer bearing cup. Then install the driven bevel gear assembled with the drive cylindrical gear into the gearbox housing and press it with a glass to a position that ensures backlash-free engagement of the bevel gear pair. When pressed, measure dimension F (see Fig. 186, 190) between the crankcase and the cup flange. After this, determine the thickness of the required shim package using the formula:

S = F + D,

where D = 0.317... 0.555 mm is the thickness of the shim package, equal to the axial displacement of the driven bevel gear to compensate for the lateral clearance in the gear mesh. After installing the driven bevel gear, tighten the bearing nuts of the drive cylindrical gear with a torque of 343 ... 392 N.m (35 ... 40 kgf.m), and the bolts securing the cover and cup with a torque of 58.9 ... 88.3 N.m (6 ... 9 kgf.m). After this, check the lateral clearance in the teeth of the conical pair, which should be 0.2 ... 0.35 mm. Measure the gap with an indicator mounted on the wide part of the tooth, and for at least three teeth of the driven gear, located at approximately equal angles around the circumference.

How to choose and buy a wheel rim for KamAZ 65115, 6520, 43118, 4310, 5320 and other models

The model range of KamAZ vehicles, depending on the area of ​​use, consists of more than a dozen vehicles. These unpretentious trucks have found their application in almost any sector of the national economy.

The specifics of working on trucks involve continuous operation of the vehicle with a minimum amount of downtime. The result is an ever-increasing need for quality spare parts.

The HARTUNG company is specialized in the production of wheel rims for a wide range of trucks, in particular for KamAZ vehicles. Using the example of several popular models of this automaker, we will consider the question of how to choose the right rims.

KAMAZ 65115

The most common and most popular model of this brand. A very powerful dump truck designed for transporting bulk materials weighing more than 11 tons. The manufacturer recommends using 22.5 or 20 inch KamAZ 65115 wheel rims on your vehicle. 20/22.5 is the diameter of the rim, and the rim width can be either 10 or 11 inches. This value directly depends on the size of the tire that will be installed on the wheel rim. Wheels of this size are widespread; many trucks of other brands are equipped with them. For example, 22.5-inch KamAZ wheel rims can be installed on some models of trucks from the brands VOLVO, MAZ, etc.

KAMAZ 6520

Another worthy representative of the flagship family. Increased maneuverability, ease of repair and maintenance, as well as the ability to transport cargo weighing 20 tons have brought this dump truck model to a leading position in the field of cargo transportation.

The wheel disk for KAMAZ 6520 is 20 inches in diameter and 8.5 inches wide. This size for wheel rims is also quite common; for example, the KamAZ 6520 wheel rim can be installed on TATRA brand trucks.

KAMAZ 4318

In terms of carrying capacity, the car is somewhat inferior to its “brothers”, but the same cannot be said about its cross-country ability. The truck behaves well on dirt roads dug up by special equipment. In its class, in terms of technical indicators, it surpasses many foreign analogues. The manufacturer recommends installing a wheel rim on KAMAZ 43118 size 10.0-20 or 12.2-20.9.

Bearing installation

First you need to install the outer races. Each clip is installed in its seat and evenly hammered down along the edges. In order to avoid chipping, it is necessary to place an old clip on the clips to be driven in. And strike her.

When the edge of the race is level with the edge of the hub surface. So that the old clip does not become fixed in the seat. It needs to be cut with a grinder. It will clog together with the installed clip. But the cut does not allow it to fit tightly. After the new clip reaches its place, the old one can be easily removed. Thanks to the cut.

Reverse gearbox or gearbox?

By the way, the gearbox will also need a clutch with a separate drive lever.

Z.Y. On Moskvich cars (except for the 400th) the gearboxes are helical, they do not howl.

They don’t howl only on the last – direct transmission.

By the way, the gearbox will also need a clutch with a separate drive lever.

Z.Y. On Moskvich cars (except for the 400th) the gearboxes are helical, they do not howl.

A. that’s probably why. Well, damn it, it broke off (. On the mentioned Muscovite there was just a Gazanov one, it still stuck out below the engine and caught on the bumps). The clutch is already overkill. Maybe it makes sense if the diesel starts with a crowbar and sucks, like one of my guys once did in Vladik). And with a starter, it’s easier to turn on the rear, start, drive away, turn off, and turn on forward.

In addition to the clutch, you also need a brake to slow down the gr.shaft, otherwise you won’t be able to turn on the gearbox.

There was a nine, I remember that to turn on the rear you need to tilt the lever to the left and then forward. If you use cables from the cockpit, you will have to turn it on with both hands using two handles, which is inconvenient.

There is a cable control of the gearbox from foreign cars = the same handle as in a car - just in any place.

  boat

I had a D-37 with urrp-25-1.5 running at 1100 rpm. The boat was around 6 tons.

D-21 is half of it, with IF 2k1 it should be quite normal to have vibration. You need to select the right supports. From the GAZelle I think it will be the same.

Vibration in all modes? Cardan with splines?

I don't agree. It is impossible to select supports for this engine for my boat, because... it's too light. The engine is two-cylinder, which is why the vibrations occur, the D37 runs much smoother. And I have a cardan, but with splines. Vibration becomes acceptable after 1400-1500 engine rpm. At these speeds the boat drives a wave, and the consumption increases.

Choosing a KamAZ gearbox: what you need to know (Diagram of KamAZ gearboxes 5320 4310 6520 65115)

Interwheel locking

The device is mounted on the cross-axle differential. When it is turned on, the torque is divided into equal parts - between the two wheels. When the MBC is turned on, the KamAZ's cross-country ability increases. This is important when driving in difficult road conditions, for example, in icy conditions. The inter-wheel lock must be turned off in time - this will prevent gearbox damage
