Check and repair
1. Before disassembly and after assembly, measure the axial clearances of the gears of the highest and lowest gears using a feeler gauge.
Permissible clearance - 0.10-0.25 mm
Retaining ring dimensions:
- label "11" - 2.30-2.35 mm
- label "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 gap - 0.019-0.068 mm
3. Checking the rear output shaft (when assembling a node).
A) Check the output shaft for wear and damage.
b) Using a micrometer, check the outside diameters of the output shaft journals.
Valid values:
- Neck "A" - 40.009 mm
- Neck "IN" - 40.009 mm
V) Mount the output shaft on the prisms.
G) 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) Use a feeler gauge to measure the clearance between the clutch and the shift fork.
Limit clearance - 1.0 mm
b) Mount the clutch on the rear output shaft and check that the clutch rotates smoothly.
