Input Shaft Inspection

NOTE:

- Wash each part and apply specified gear oil to sliding faces of bearing and gear.

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.





3) Install new snap ring (2) in specified direction as shown in figure and then drive in input shaft front bearing (1) to input shaft using special tool and hammer.

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.
a) Fit high speed synchronizer sleeve to hub in specified direction as shown in figure.
b) Insert 3 keys (2) to hub.
c) Set springs (1) at specified position as shown in figure.

Synchronizer key installation position
: A = B











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.

7) Check 4th gear (1) thrust clearance by using thickness gauge. If clearance is out of specification, repress-fit or replace defective part.

4th gear thrust clearance
"a": 0.10 - 0.30 mm (0.004 - 0.012 in.)






8) Apply oil to high speed gear needle bearing, and then install 3rd gear bush (1), high speed gear needle bearing (2) and 3rd gear (3).











9) Press-fit 5th speed synchronizer hub (1) using special tool and hydraulic press.

10) Check 3rd gear (1) thrust clearance by using thickness gauge. If clearance is out of specification, repress-fit or replace defective part.

3rd gear thrust clearance
"a": 0.10 - 0.30 mm (0.004 - 0.012 in.)





11) Tighten input shaft 5th hub nut to specified torque in the same manner as Step 3) of Disassembly Input Shaft Disassembly.

Tightening torque
Input shaft 5th hub nut 210 Nm (21.0 kgf-m, 152.0 lbf-ft)

12) Caulk input shaft 5th hub nut (2) using caulking tool.
