2. Check the condition of all shafts and gears. Replace worn or damaged components.
3. Check the drive chain for cracks, signs of wear and damage.
4. Inspect the bearings for signs of wear and damage. Check that they rotate freely.
5. Check the condition of the synchronizer sliding keys and their spring.

6. Check the synchronizer locking ring for cracks, deformation and damage. Fully seat the ring on the clutch gear of the driven shaft. Measure the gap between the gear and the locking ring (see accompanying illustration). Compare the measurement result with the regulatory requirements (see size and adjustment tables at the end of the Manual), replace the ring and/or gear if necessary.
7. Check the shift lever, rods and forks for signs of wear, damage and deformation. Make sure the sliding surfaces are smooth. Check the tension force of the locking springs.
8. Check the crankcases for cracks and other damage.
9. Replace defective components.
Note: If the control lever or its mounting pin require replacement, they should be replaced as a set.
