Back Idle Gear, Shaft and Needle Bearing
1. Check the needle bearing for abrasion, color change, or other
damage.
2. If there is any doubt as to the condition of a needle bearing,
replace it.
3. Check both the shaft and gear bearing surface.

6T Spiral Bevel Pinion Shaft Turning Torque
NOTE
• It is necessary to adjust the pinion gear shaft turning
torque, when replacing the 6T spiral bevel pinion shaft,
taper roller bearing or other relative parts.
1. Assemble the 6T spiral bevel pinion shaft (1) to the front case.
At this time, install the same shim (2) to bearing holder side.
2. Tighten the bearing holder mounting screws to specified torque.
3. Check the turning torque by using the allen socket with torque
wrench.
4. Add or reduce the thickness of shim (2) to make the specified
turning torque.
(Reference)
• Thickness of shims
0.10 mm (0.0039 in.)
0.15 mm (0.0059 in.)
0.20 mm (0.0079 in.)
0.30 mm (0.012 in.)
0.50 mm (0.020 in.)

Backlash between Differential Pinion and Differential Side
Gear
1. Secure the differential case with a vise.
2. Put the solder (0.50 mm (0.020 in.) thickness) on the position
where the tooth of the differential side gear.
3. Temporarily install the propeller shaft assembly and rotate the
propeller shaft carefully.
4. Measure the backlash by thickness of the point where solder is
the thinnest.
5. If the backlash exceeds the allowable limit, adjust with
differential side gear shims.
(Reference)
• Thickness of shims
1.5 mm (0.059 in.)
1.6 mm (0.063 in.)
1.7 mm (0.067 in.)
