Disassembly
1. Remove retaining ring 2 and thrust washer 3.
2. Remove 4th gear gear 4 and needle bearing 5, marking it.
3. Remove retaining ring 7.
4. Mark the position of the coupling and synchronizer hub relative to the shaft.
5. Press synchronizer 8 complete with blocking rings 6 and 9 and gear 10 of 3rd gear (applying force to the 3rd gear).
6. Remove the needle bearing 11 of the 3rd gear and mark it.
7. Press the middle bearing inner race off the shaft.
Assembly
1. Press the inner race of the middle bearing onto the shaft.
2. Install the needle bearing 11 of the 3rd gear on the input shaft, after lubricating it with gear oil.
3. Install gear 10 3rd gear.
4. Install the 3rd and 4th gear synchronizer assembly with blocking rings in accordance with the previously made marks. (Disassembly and assembly of the synchronizer are described in subsection 7.4.1.4). In this case, the gap between the 5th gear gear and the blocking ring should be 1.0–1.9 mm (minimum allowable gap 0.5 mm). Otherwise, the blocking ring must be replaced.
5. Install retaining ring 7.
6. Install needle bearing 5 and gear 4 in 4th gear onto the shaft.
7. Install thrust washer 3 and circlip 2.
8. Using a feeler gauge, check the axial clearance between the 4th gear and the thrust washer, which should be 0.10–0.40 mm. If the gap is not as specified, select a new thrust washer 3 of the required thickness and replace. Thrust washers with a thickness of 3.47 are supplied as spare parts; 3.57 and 3.67 mm.
