4. Apply oil to high speed gear needle bearing (6), and then install needle bearing, 4th gear (5) and high speed synchronizer ring (7) to input shaft.
5. Assemble synchronizer sleeve (4) and hub (3) as follows.
   1. Fit high 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 high 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 4th gear after press-fitting sleeve & hub assembly.
