8.Remove cap screw and flange nut that secures front corner of 4WD hydraulic manifold to rear frame mount.
9.If required, remove tie rod ends from steering arms on rear axle (Fig. 12). Remove the cotter pins and castle nuts from the tie rod ball joints. Use a ball joint fork and remove the tie rod ends from the axle steering arms.
10.Support rear axle to prevent it from falling. Remove six (6) cap screws, flat washers and flange nuts that se- cure rear frame mount to equipment frame. Lower rear axle and rear frame mount from machine.
11.Remove lock nut and washer from pivot pin that at- taches rear axle to rear frame mount. Remove washer head screw that secures flange of pivot pin to frame mount (Fig. 13).
12.Remove pivot pin. Separate rear frame mount from rear axle. Note location of thrust washers on both ends of axle mounting boss.
Installation (Fig. 10)
1.Position rear frame mount to axle. Install thrust washers between axle boss and frame mount. The thin- ner thrust washer should be installed on the hydraulic motor end of the axle (toward the rear of the machine). With washers installed, there should be from 0.002” to 0.020” (0.05 mm to 0.51 mm) clearance between rear frame mount and axle mounting boss. Add thrust wash- ers if needed to adjust clearance.
2.Install axle pivot pin to secure axle to rear frame mount. Tighten lock nut and then loosen it slightly to al- low the axle pin to pivot freely. Secure pivot pin to frame mount with washer head screw (Fig. 13).
3.If removed, install the tie rod to rear axle (Fig. 12). Tighten ball joint castle nuts and install new cotter pins.
4.Position axle and rear mount under machine with a jack. Raise assembly to machine frame and align mounting holes of rear mount and machine frame.
5.Secure rear mount to frame with six (6) cap screws, flat washers and flange nuts.
6.Install cap screw and flange nut that secures front corner of 4WD hydraulic manifold to rear frame mount.
7.Attach steering cylinder hydraulic tubes to rear frame mount with washers and bulkhead lock nuts (Fig. 11). Install steering cylinder hoses to hydraulic tubes.
