Chassis - Articulation and Oscillation Pivot
assembly to avoid damage to end threads.
18. Replace thrust nut (34) on pivot (1) to protect
threads.
19. Note position of front 'V' ring (41) to aid in
'Installation'. Remove and discard 'V' ring (41).
20. Inspect oscillation bushes (43) as described in
'Inspection'. If bushes are to be renewed, proceed with
Step 21.
21. Remove oscillation bush/es (43) with hammer and
chisel.
Note: The suggested method is to make an axial cut
along the bush then to lever the bush in order to
collapse it upon itself.
Inspection
Numbers in parentheses refer to Fig. 1.
1. Clean oscillation bushes (43) with a suitable solvent
and allow to dry.
2. Inspect oscillation bushes (43) 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.
Installation
Numbers in parentheses refer to Fig. 1, unless
otherwise specified.
Note: Tighten all fasteners without special torques
specified, to standard torques listed in
Section 300-0080, STANDARD BOLT AND NUT
TORQUE SPECIFICATIONS.
WARNING
To prevent personal injury and property
damage, make sure blocking or lifting
equipment is properly secured and of adequate
capacity to do the job safely.
1. Wipe bush housing clean using suitable solvent and
allow to dry.
2. Apply LOCQUIC primer to housing and allow to dry
for 10 minutes. Apply LOCTITE RC-35 to housing.
3. Align new bushes to housing with grease holes aligned
vertically and identification 'PAINT DOT' at Top Dead
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.
8. Remove bolts (1, Fig. 3), lockwashers (2, Fig. 3),
nuts (3, Fig. 3) and protective guard (4, Fig. 3), if fitted,
from beneath rear of pivot housing.
WARNING
Tensioned spring on adjuster.
9. Slacken adjuster (14, Fig. 3) until brake pads
(13, Fig. 3) are sufficiently clear of parking brake disc
(5, Fig. 3) to permit removal of calliper (7, Fig. 3).
10. Note positions of front and rear wedge plates
(8 & 9, Fig. 3) to aid in 'Installation'. Remove bolts
(6, Fig. 3), washers (11, Fig. 3), nuts (12, Fig. 3), front
and rear wedge plates (8 & 9, Fig. 3) and left hand
torque plate (10, Fig. 3).
11. Move and secure calliper (7, Fig. 3) clear of
parking brake disc (5, Fig. 3).
Note: Take extra care when handling drivelines since
any deformity on a rotating mass creates vibration and
excessive wear during any operation.
12. Match mark brake yoke (16) and mating surface of
pivot - centre axle driveline (Fig. 2) to aid in
'Installation'. Remove bolts, lockwashers and caps and
remove driveline from the machine.
13. Mark disc (5, Fig. 3) assembly to aid in 'Installation'
then remove bolts (15, Fig. 3) washers (16, Fig. 3) and
disc (5, Fig. 3).
14. Remove bolts (36), lockwashers (14) and
lockplate (35).
15. Using special tool, which can be fabricated as
shown in Fig. 11, remove thrust nut (34) from pivot (1).
Note position of rear 'V' ring (41) to aid in 'Installation'.
Remove and discard 'V' ring (41).
16. Attach suitable lifting equipment to the front of the
rear frame and take up slack.
17. Remove all blocking from rear frame and wheels
and using suitable lifting equipment draw the rear
frame from pivot (1) assembly. When clear, block the
rear frame and wheels.
Note: Use care when separating rear frame and pivot
