Tighten two bolts (14) to a torque of [while rotating gear (18) with gear (19)] 34 m (25 lb ft)b. Loosen two bolts (14); retorque [while rotating gear (18) with gear (19)] to a torque of 17 N m (13 lb ft)c. Use Tool (D) to measure the gap between the face of retainer (15) and face of case assembly (12) near two bolts (14).d. Remove retainer (15) and install two dowels (16) to dimension (X) in retainer.Dimension (X): 11.0 0.5 mm (0.43 0.02 in).e. Determine the amount of shims (Y) needed from the average gap measured in Step 9c. and add another 0.20 mm (.008 in) for the correct shims required.f. Remove two bolts and washers (14) from retainer (15). 9. Place shims (Y) (determined in Step 9e.) in position and reinstall retainer (15) to case assembly (12). a. Install seven bolts and washers (14) to retainer (15).b. Tighten bolts (14) to a torque of 270 40 N m (200 30 lb ft) c. Use Tooling (A) for a final end play check.d. End play range 0.000 0.076 mm (.0000 .0030 in)e. If end play is not within specification in Step 9d., add or subtract shims as needed, following Steps 8. and 9.10. Apply 5P-0960 Multipurpose Grease to the splines of the shaft that gear (18) engages with.
