Chassis - Articulation and Oscillation Pivot Section 100-0020 pivot assembly (1). Disconnecting Front and Rear Frames 7. Fill bearing housings with Extreme Pressure Lithium Complex No. 2 grease (23), through lube fittings (27), until excess grease starts to escape from seal housings (32 & 34). 1. Position the vehicle on a level work area and apply parking brake. 2. Raise body and install body safety prop to secure body in partially raised position. 8. Remove lube fittings (27) and reinstall plugs (28). Store lube fittings (27) on pad on side of pivot assembly (1). 3. Shut down engine and block all wheels securely. 4.
Depress and release brake pedal continuously to relieve the pressure in the braking system. 9. Start engine, raise body, lower body safety prop and lower body. 5. Carefully loosen brake lines at base of both accumulators to check that the pressure has released. Re-tighten brake lines. 10. Remove wheel blocks. OSCILLATION COMPONENTS 6. Tag all hydraulic lines and electrical wiring between front and rear frames to ensure correct assembly/ installation. Disconnect all hydraulic lines and plug openings to prevent ingress of dirt. Disconnect electrical wiring and any other attachments which could be damaged on separation of front and rear frames. Numbers in parentheses refer to Fig. 1. Note:
The following procedure assumes that only components associated with oscillation require repair. Note: It is necessary to disconnect the front and rear frames at the articulation point to service the oscillation components. 7. Identify the relationship of the driveline caps to the transmission yoke and front yoke (17). Remove capscrews and remove driveline from the vehicle. Note: It is essential that the grease used for oscillation components is Extreme Pressure Multipurpose Grease (26), as specified in Section 300- 0020, LUBRICATION SYSTEM. 8. Support tractor frame at front and rear with suitably placed stands or timbers to keep the frame level during and after pin removal. Note:
Tighten all fasteners without special torques specified to torques listed in Section 300-0080, STANDARD BOLT AND NUT TORQUE SPECIFICATIONS. 9. Remove bolts, washers and pins securing steering cylinders to pivot. Secure steering cylinders clear of pivot. 10. Release the parking brake by turning the hex- head on the parking brake actuator fully anticlockwise. 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. WARNING Tensioned spring on adjuster. 11. Attach suitable lifting equipment to pivot/rear frame assembly.
Lifting equipment must prevent pivot from oscillating after separation, and, be capable of pulling pivot/rear assembly clear of front frame. Raise lifting equipment to support pivot/rear frame assembly. 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. Hydraulic fluid pressure will remain within the braking system after engine shut down. Operate the treadle pedal continuously until the pressure has dissipated before carrying out any work on the braking system or serious injury could result. 12. Remove bolt, washer, large nut (42) and washer (41) securing upper pin (40). 13.
Remove upper pin (40). If necessary tap upper pin (40) to ease removal taking care to avoid damaging the threads. Note: It may be necessary to relieve binding between SM 1373 Rev 2 8-03 7
