Gap:
- nominal - 0.05 - 0.40 mm
- maximum allowable - 0.5 mm
If the clearance is not within the standard, replace the gear shift fork and synchronizer sleeve.
2. Using a feeler gauge, measure the gap between the synchronizer ring and the side surface of the gear along the entire circumference.
Gap:
- nominal - 0.8 mm
- maximum allowable - 1.5 mm
If the gap is not within the norm, replace the synchronizer ring.
3. Measure the length of the springs in a free state.
Nominal length:
- first and second gear shift rod retaining spring - 22.5 mm
- third and fourth gear shift rod retaining spring - 22.5 mm
- 1st and 2nd gear shift rod tip spring - 22.8 mm
- 5th and reverse gear shift rod tip spring - 41.0 mm
- 5th and reverse gear shift rod retaining spring - 24.97 mm

If the spring length is not within the standard, replace the spring.
4. Measure the radial runout of the secondary shaft.
- Radial runout - 0.23 mm
If the shaft runout does not meet the established norm, replace the secondary shaft.
5. Using a feeler gauge, measure the gap between the shift rod tip and the control lever.
- Nominal clearance - less than 0.5 mm
