A/T Countershaft 2nd Gear and 5th Gear Axial Clearance Inspection

Special Tools Required

- Driver Handle, 40 mm I.D. 07746-0030100

1. Slide the park gear (A) over the countershaft (B).






2. Place the park gear (A) on press bases (B), and place a spacer (C) between the countershaft (D) and the press to prevent damaging the countershaft.






3. Install the park gear using a press.

4. Install the 53 x 57 x 20 mm needle bearing (A), 1st gear (B), 5th gear (C), the 42.5 x 52.5 x 2.5 mm thrust washer (D), the 5th gear collar (E), the selected 42.5 mm thrust shim (F), and 2nd gear (G) on the countershaft (H). Install 5th gear, and 2nd gear in the direction shown.






5. Install the ball bearing (A) over the countershaft (B), then press it into place using the 40 mm driver handle and the press.






6. Secure the final drive gear part of the countershaft in a bench vise with wood blocks, install the old lock bolt (A), and tighten it to 125 N-m (12.7 kgf-m, 92 lbf-ft).
The lock bolt has left-hand threads.

NOTE: After this procedure, remove wood chips that may be stuck to the gear.






7. Measure the clearance between the 5th gear collar (A) and the 42.5 mm thrust shim (B) with a feeler gauge (C) in at least three places. Use the average as the actual clearance.










8. If the clearance is out of the standard, remove the 42.5 mm thrust shim and measure its thickness.

9. Select and install a new 42.5 mm thrust shim, then recheck the clearance.
