Lightly coat 'V' ring (10) and machined surfaces of pivot with Extreme Pressure Multipurpose Grease (26) and, install 'V' ring (10), with lip towards rear, on front of oscillation hub. 7. Using suitable lifting equipment, and taking care to prevent damaging bushes (2) or pivot threads, install pivot assembly (1) into rear frame. 8. Lightly coat 'V' ring (10) and machined surfaces of pivot with Extreme Pressure Multipurpose Grease (26) and, install 'V' ring (10), with lip towards front, on rear of oscillation hub. Fig.

4 - Installing Oscillation Bushes 2. Inspect nylon oscillation bushes for wear, scoring, erosion and 'out of round'. Pay particular attention to the thrust faces of the bushes which should also be inspected for cracking/splitting. Renew if required. 9. Thread thrust nut (11) on pivot assembly (1) and tighten as follows: a) Restrain pivot assembly (1) to prevent it oscillating, by placing a heavy bar between the steering cylinder mountings. Lock the bar in position using suitable trestles or stands. See Fig. 3. 3. Replace all seals with new parts. Assembly Numbers in parentheses refer to Fig. 1.

b) Secure a suitable tool to pivot thrust nut (11) and tighten thrust nut (11) until there is no end float/ clearance at thrust face of either bush. Slacken thrust nut (11) until pin of the locking plate (12) can be inserted in the first available hole in the thrust nut (11). Note: Tighten all fasteners without special torques specified to torques listed in Section 300-0080, STANDARD BOLT AND NUT TORQUE SPECIFICATIONS. c) Secure locking plate (12) with bolts (22) and lockwashers (21). Torque tighten bolts (22) to 94 Nm (69 lbf ft). WARNING To prevent personal injury and property damage, be sure wheel blocks are properly secured and of adequate capacity to do the job safely. 10.

Install adaptor (57), connector (58), elbow (59) and pipe assembly (60) to oscillation hub. 11. Install brake yoke (18) on driveshaft (14) until it butts against bearing assembly cup and cone (8 & 9). 1. Wipe bush housing clean using a suitable solvent and allow to dry. 12. Install parking brake disc on brake yoke (18) and secure with bolts, washers and nuts. Tighten bolts to a torque of 73 Nm (54 lbf ft). 2. Apply Loctite 648 (3) and Loc Quick Primer (4) and align new bushes (2) to housing with grease holes aligned vertically and identification 'PAINT DOT' at Top Dead Centre. Refer to Fig. 4. Drift bushes (2) into housing using hammer with soft packing for protection. 13.

Install thrust washer (16) on rear of driveshaft (14). 14. Install nut (19) at rear of driveshaft (14), and tighten nut (19) to a torque of 250 Nm (180 lbf ft) to seat bearing cup and cone (8 & 9) assemblies. 3. Install plug (25) in filler/level hole on pivot assembly (1). Install gasket (5) and cover plate (6) on side of oscillation hub and secure with bolts (7) and washers (20). 15. Chap driveshaft (14) at both ends with a hide-faced hammer. Re-torque nut (19) to 250 Nm (180 lbf ft). 4. Install plug (25) in cavity drain port on underside of oscillation hub. 16. Back off nut (19) four flats, and chap rear end of driveshaft (14) with a hide-faced hammer to remove SM 1373 Rev 2 8-03 9
