Put retainer (26) in position, and install the bolt that holds the retainer in place.
Put cage (32) in position without the shims. Install the two bolts (35) directly across from each other.
Tighten bolts (35) to a torque of 2.3 N m (20.0 lb in).
Rotate the gear at least five revolutions. Tighten the bolts to a torque of 4.5 N m (40.0 lb in).
Rotate the gear again at least five revolutions. Tighten the bolts again to a torque of 4.5 N m (40.0 lb in).
Use a feeler gauge, and measure the gap between cage (32) and the cover at the location of bolts (35). Average the two measurements.

Remove bolts (35) and cage (32) from the cover.
Install shims (36) that are equal to the measurement in step 37 plus 0.18 mm (0.007 inch).
Put cage (32) in position on the shims, and install bolts (35). Tighten the bolts to a torque of 135 15 N m (100.0 11.0 lb ft).

Use Tooling (D) and Tooling (F) to check the end play of the gear per the following steps.
Push down the gear and hold the gear with Tooling (F). Rotate the gear with a ratchet wrench at least five revolutions. Watch for movement of the dial indicator. Stop rotating the gear at the point of maximum needle movement.
Zero the dial indicator. Put a mark at the location of maximum needle movement.
Pull the gear upward with Tooling (F). Rotate the gear at least five revolutions. Stop the gear at the same point of maximum needle movement. Record the measurement. This measurement is the actual end play of the gear.
Repeat Steps 41.a through 41.c. The measurement should not change. The end play of the gear must be 0.05 mm (0.002 inch) to 0.15 mm (0.006 inch).

Install plate (37) in order to hold the gear while the backlash is checked.
Put Tooling (D) in position with the point of the dial indicator against gear (8).
Use Tooling (D) to measure the backlash of gear (8) at three evenly spaced locations. The difference in the three measurements should not be more than 0.08 mm (0.003 inch).
Illustration 24 g00742459
Add shims or remove shims (38) in order to obtain a backlash of 0.020 mm (0.008 inch) to 0.030 mm (0.012 inch). Remove plate (37) after the backlash has been adjusted.
