If replacement of the gearbox, clutch, the shaft itself or tapered roller bearings, the input shaft is subject to adjustment. Assembling of the shaft is carried out in sequence, return dismantling, using Fig. 182. In addition to the adjustments necessary to pay attention to the following points:

|
- Collect synchronizer 13 must be in the reverse order of its disassembly. As already mentioned, the sliding sleeve and the hub can not razukomplektovyvat inclusions, they must be replaced in the assembly. Most of the length of the side gears, interrupted annular recess (lower arrow, Fig. 195), should be facing toward the inclusion of the fourth transmission gear. Additional marking annular groove (upper arrow) must also be turned towards a fourth gear; - Drive to the end of the shaft inner ring 8 (see. Fig. 182) must be under the pressure of the tapered surface of the roller to the outside; - Establish a synchronizer ring to gear and transmission, as shown in Fig. 196, and measure the probe gap. Clearance (wear limit) of 0.5 mm (the new 1.3-1.7 mm);

- Lubricate the needle bearing 8 (see. Fig. 182), Push it to the shaft and install pinion bearing 9 third gear. Install the synchronizer ring 10. Install the thrust washer 11. With the help of special pliers used for repairing water pumps, make it ring in the annular groove; - Install the shaft under a press and press in the synchronizer by a piece of pipe in the shaft. Since the annular groove in the gearing is no longer visible, the control of the correctness of the hub pressing inclusion should be carried out with the help of the marking ring recess, located on the upper side (upper arrow in Fig. 195); - Install the thrust ring 13 (see. Fig. 182), and insert the ring 14; - Set fourth speed gear 15 with a needle bearing 16 and the shim 17 and drive the tapered roller bearing 18 on the shaft end. If none of the above parts are not replaced, the shaft can be re-installed. Otherwise perform the following measurements: - Press in the outer ring 20 of the bearing without shims 19 all the way into the clutch housing. Insert the drive shaft in the gearbox housing, install the clutch housing and tighten the bolts sump 25 N ?� m;

|
- Set in the housing shown in Fig. 193 the special tool, but measuring plate should be installed at this time of the end of the drive shaft. Rotate the shaft several times to ensure complete self-adjustment of bearings; - Pre-set tension indicator on the pointer equal to 1.0 mm, and move the arrow to zero; - Squeeze the shaft towards the dial gauge and record the reading (for example, 1.21 mm) dial indicator. Sales have washers of different thickness, based on the measured values may be required to purchase a washer. The measurements were carried out several times in order to avoid mistakes during assembly; - Again to remove the drive shaft and remove the thrust ring of the bearing mounting, as shown in Fig. 173;

|
- Drive back bearing ring with some shims (washers or two, depending on the measurement result, in the example contains a washer thickness 1.20 mm), reinstall the drive shaft, and again put on the crankcase bolts. Several times turn the shaft that could be earned extra bearings; - Repeat the specified measurements. With proper adjustment dial gauge reading should now be in the range 0.01-0.12 mm. Thus, transmission is adjusted in accordance with the instruction, it can be finally collected.
