Countershaft Disassembly and Reassembly: Reassembly

Reference: COUNTERSHAFT AND REVERSE IDLER GEAR INSPECTION 

1. Clean all components thoroughly, inspect them for any abnormality and replace with new ones as necessary.
2. To ensure lubrication, air blow oil holes (1) and make sure that they are free from any obstruction.

4. Apply oil to countershaft gear needle bearing (6), and then install needle bearing, 2nd gear (5) and low speed synchronizer ring (7).
5. Assemble synchronizer sleeve (4) and hub (3) as follows.
   1. Fit low speed synchronizer sleeve to hub in specified direction as shown in figure.
   2. Insert 3 keys (2) to hub.
   3. Set springs (1) at specified position as shown in figure.

6. Drive in low speed synchronizer assembly (1) using special tool and hydraulic press.
   NOTE:

   • While press-fitting sleeve & hub, make sure that synchronizer ring key slots (2) are aligned with keys in sleeve & hub assembly.
   • Check free rotation of 2nd gear after press-fitting sleeve & hub assembly.
