Checking and repair
1. Before disassembling and after assembly, measure the axial clearances of the high and low gears using a feeler gauge.
Permissible gap - 0.10-0.25 mm
Snap ring sizes:
- mark "11" - 2.30-2.35 mm
- mark "17" - 2.60-2.65 mm
2. Using a dial indicator, measure the radial clearances of the high and low gears with the needle bearing installed.
Permissible clearance - 0.019-0.068 mm
3. Checking the rear output shaft (when assembling a unit).
a) Check the output shaft for wear and damage.

b) Using a micrometer, check the outside diameters of the output shaft journals.
Acceptable values:
- Neck "A" - 40.009 mm
- Neck "B" - 40.009 mm
c) Mount the output shaft on the prisms.
d) Using a dial indicator, measure the runout of the output shaft.
Limit runout —— 0.03 mm
4. Checking the high-low gear shift clutch.
a) Using a feeler gauge, measure the gap between the clutch and the high-low gear shift fork.
Maximum clearance - 1.0 mm
b) Install the coupling on the rear output shaft and check the smooth rotation of the coupling.
