A/T Mainshaft 3rd Gear Axial Clearance Inspection

Inspection

1. Mainshaft - Inspection

1. Inspect the thrust needle bearing and the needle bearing for galling and rough movement.

2. Inspect the splines for excessive wear and damage.

3. Check the shaft bearing surface for scoring and excessive wear.

2. 3rd Gear Axial Clearance - Inspection





1. Install the thrust needle bearing (A), 3rd gear (B), the needle bearing (C), the thrust needle bearing (D), the 40 x 63 mm thrust washer (E), the 3rd/5th clutch (F), the 5th gear collar (G), and the transmission housing bearing (H)

NOTE: Do not install the O-rings during inspection.

2. Install the idler gear (I) on the mainshaft by a press, then install the conical spring washer (J) and the locknut (K).





3. Set a dial indicator (A) on 3rd gear (B).





4. Lift 3rd gear (A) up while holding the mainshaft, and use the dial indicator (B) to read the 3rd gear axial clearance.

5. Measure the 3rd gear axial clearance in at least three places while moving 3rd gear. Use the average as the actual clearance.

Standard: 0.04-0.10 mm (0.0016-0.0039 in)





6. If the clearance is out of the standard, remove the 40 x 63 mm thrust washer, and measure its height.

7. Select and install a new thrust washer, then recheck.






8. After replacing the thrust washer, make sure the clearance is within the standard.

9. Disassemble the installed parts from the mainshaft.
