Section 100-0020 Chassis - Articulation and Oscillation Pivot 21. Tighten nut (19) until end play on driveshaft (14) can just be felt. Take dial indicator reading of end play. Tighten nut (19) until end play on driveshaft (14) is 0.05 - 0.15 mm (0.002 - 0.006 in). 33. Install parking brake disc protective guard (if fitted) and secure with bolts, washers and nuts. Tighten nuts to a torque of 73 Nm (54 lbf ft). 34. Start engine, raise body, lower body safety prop and lower body. Note: One flat on nut (19) turned is equivalent to 0.025 mm (0.001 in). 35. Remove wheel blocks. 22.
When correct end play is obtained, remove dial indicator and secure nut (19) by bending the first available lockwasher (50) tab into nut (19). Recheck end play. ARTICULATION COMPONENTS Numbers in parentheses refer to Fig. 1, unless otherwise specified. 23. Install parking brake disc on brake yoke (18) and secure with bolts and washers. Tighten bolts to a torque of 73 Nm (54 lbf ft). Note: The following procedures assume that only components associated with articulation require repair. 24. Install parking brake assembly to mounting brackets and secure with bolts, washers and nuts. Refer to Section 170-0010, PARKING BRAKE AND MOUNTING. Note:
It is essential that the grease used for articulation components is Extreme Pressure Lithium Complex No. 2 (23), as specified in Section 300-0020, LUBRICATION SYSTEM. 25. Apply parking brake by turning the hex-head on the parking brake actuator fully clockwise. Note: Tighten all fasteners without special torques specified to torques listed in Section 300-0080, STANDARD BOLT AND NUT TORQUE SPECIFICATIONS. 26. Apply Loctite 638 to the threads of capscrews used to mount driveline to brake yoke (18). Align match marks and install driveline. Tighten capscrews to a torque of 153 Nm (113 lbf ft).
WARNINGS To prevent personal injury and property damage, be sure wheel blocks, blocking materials and lifting equipment are properly secured and of adequate capacity to do the job safely. 27. Apply Loctite 638 to the threads of capscrews used to mount driveline between transmission yoke and front yoke (17). Align match marks and install driveline. Tighten capscrews to a torque of 153 Nm (113 lbf ft). 28. Remove bolts (7), washers (20), gasket (5) and cover plate (6) from side of oscillation hub to gain access to filler/level hole plug (25) on pivot assembly (1). Remove filler/level plug (25).
When necessary to drive out or drive on components during disassembly/assembly, be sure to use a soft drift to prevent property damage and personal injury. 29. Add SAE 80W - 90 E. P. gear oil (24) through filler/ level hole in pivot assembly (1) until the oil is level with the bottom of filler/level hole. Disconnecting Front and Rear Frames Note: The front and rear frames can be separated sufficiently to permit disassembly/assembly of the articulation components without disconnecting hydraulic lines or electrical wiring. 30.
Remove plug (25) from underside of oscillation hub to drain the cavity between the oscillation hub and pivot assembly (1) of any oil that entered while filling the driveshaft bearing housing. 1. Position the vehicle on a level work area and apply parking brake. 31. Install plug (25) into filler/level hole on pivot assembly (1). Install gasket (5) and cover plate (6) on side of oscillation hub, secure with bolts (7) and washers (20). 2. Raise body and install body safety prop to secure body in partially raised position. 32. Install plug (25) into cavity drain port on underside of oscillation hub. 3. Shut down engine and block all wheels securely. 4.
