Section 100-0020 Chassis - Articulation and Oscillation Pivot pre-load from bearing cup and cone assemblies (8 & 9). frame and bearing bores. 17. Remove nut (19) from rear of driveshaft (14), install lockwasher (50) and reinstall nut (19). 7. Apply Loctite 243 (49) to threads of bolt (48). Secure lower pin (43) with bolt (48) and hardened washer (44). Tighten bolt (48) to a torque of 73 Nm (54 lbf ft). 18. Set up dial indicator with pointer positioned on rear end face of driveshaft (14). Push and pull on parking brake disc to move driveshaft (14) backwards and forwards, remembering to rotate shaft at the same time to obtain an accurate reading. Note dial indicator reading. 8.
Smear upper pin (40) with Extreme Pressure Lithium Complex No. 2 grease (23) and install through front frame and bearing bores. 9. Apply Loctite 243 (49) to threads of bolt (62). Secure upper pin (40) with bolt (62), washer (61), washer (41) and large nut (42). Tighten nut (42) to a torque of 1 425 Nm (1 050 lbf ft). 19. 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). Note: One flat on nut (19) turned is equivalent to 0.025 mm (0.001 in) axial movement. Final Assembly 1.
Install parking brake assembly to mounting brackets and secure with bolts, washers and nuts. Refer to Section 170-0010, PARKING BRAKE AND MOUNTING. 20. 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. 2. Apply parking brake by turning the hex-head on the parking brake actuator fully clockwise. Connecting Front and Rear Frames 1. Install spacer (39) in upper bearing assembly (30) as noted on removal. WARNING Tensioned spring on adjuster. 2. Smear bearing assembly (30) and pin bores with Extreme Pressure Lithium Complex No. 2 grease (23). 3.
Remove lifting equipment from pivot/rear frame assembly. 3. Attach suitable lifting equipment to pivot/rear frame assembly. Lifting equipment must prevent pivot from oscillating and be capable of pulling pivot/rear frame assembly to align pivot bearing bores and front frame pin bores. Raise lifting equipment to support pivot/rear frame assembly. 4. Remove stands or timbers from front frame. 5. Apply Loctite 270 to 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). 4. Remove blocks from rear wheels and blocking from pivot/rear frame assembly.
Using lifting equipment, pull pivot/rear frame assembly to align pivot bearing bores and front frame pin bores. Block wheels and block pivot/rear frame assembly to remain level and stationary. 6. Align match marks and reconnect driveline to brake yoke (18). Tighten capscrews to a torque of 153 Nm (113 lbf ft). Note: Take extra care when handling drivelines as chips, dents, burrs or deformity on any rotating mass creates vibration and excessive wear during any operation. 5. Freeze upper and lower pins (40 & 43) to ease installation. 7. Align steering cylinder bores and mounting pin bores on pivot. Install pins and secure with bolts and washers. Tighten bolts to a torque of 73 Nm (54 lbf ft).
Note: It may be necessary to relieve binding between the pin and pin bores by raising or lowering pivot/rear frame assembly. 6. Smear lower pin (43) with Extreme Pressure Lithium Complex No. 2 grease (23) and install through front 8. Connect hydraulic lines and electrical wiring as noted on disassembly. SM 1373 Rev 2 8-03 10
