Complex No. 2 grease (23), through lube fittings (27),
until excess grease starts to escape from seal
housings (32 & 34).
8. Remove lube fittings (27) and reinstall plugs (28).
Store lube fittings (27) on pad on side of pivot
assembly (1).

OSCILLATION COMPONENTS
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.
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.
Note: Tighten all fasteners without special torques
specified to torques listed in Section 300-0080,
STANDARD BOLT AND NUT TORQUE
SPECIFICATIONS.
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.
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.
Chassis - Articulation and Oscillation Pivot
Disconnecting Front and Rear Frames
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.
3. Shut down engine and block all wheels securely.
4. Depress and release brake pedal continuously to
relieve the pressure in the braking system.
5. Carefully loosen brake lines at base of both
accumulators to check that the pressure has
released. Re-tighten brake lines.
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.
7. Identify the relationship of the driveline caps to the
transmission yoke and front yoke (17). Remove
capscrews and remove driveline from the vehicle.
8. Support tractor frame at front and rear with suitably
placed stands or timbers to keep the frame level
during and after pin removal.
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.
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.
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
