secure pins (35) in place with washers (38),
lockwashers (36) and bolts (37).
Note: Ensure that there is at least 2/3 mounting
surface area contact. Check contact area using a
0.05 mm (0.002 in) feeler gauge.
13. Using a suitable solvent, clean equalizer beam (4)
shaft on the frame. Install new 'V' ring seal (13) and
new wear rings (20) on the shaft with flanges to the
inside. Ensure mounting holes on the ends of the shaft
are clean.
14. Using a suitable solvent, clean the bores of
equalizer beams (4). Install new bushings (21) in
equalizer beams (4) aligning holes in bushings with
holes in equalizer beams.
15. Using suitable lifting equipment, install equalizer
beam (4) on frame shaft. Apply Loctite 243 to bolts
(24) and secure equalizer beam (4) to shaft with bolts
(24), washers (23) and retaining plate (22). Tighten
bolts (24) to a torque of 169 Nm (125 lbf ft).
16. Apply Loctite 243 to bolts (26). Install cover plate
(25) to equalizer beam (4) and secure with bolts (26)
and washers (17). Tighten bolts (26) to a torque of
73 Nm (54 lbf ft).
17. Apply Loctite 243 to lube fitting (27) and install in
cover plate (25). Lubricate with grease specified in
Section 300-0020, LUBRICATION SYSTEM, until
excess lube is seen.
18. Repeat steps 15 through 17 to install opposite
equalizer beam (4).
19. Connect interleaf mounts (7) to equalizer beams (4)
with bolts (29), lockwashers (19) and locknuts (30).
Tighten bolts (29) to a torque of 169 Nm (125 lbf ft).
20. Remove caps and connect hydraulic brake lines to
tees on centre axle and rear axle assemblies.
21. Using suitable blocking equipment, block equalizer
beams (4) to prevent movement when installing rear
wheels.
22. Secure manifold brackets (46) to equaliser beams
(4), using bolts (44) and washers (45). Fit elbows (40 &
41) to panhard rods (31) and nipples (42).
23. Route grease lines (47 & 48); securing to manifold
brackets (46), using clips (49), lockwashers (43) and
bolts (50). Connect grease lines (47 & 48) to their
respective elbows (40 & 42).
24. Using suitable lifting equipment, position one tyre
and rim assembly on one rear wheel and secure with
wheel nuts.
25. Repeat step 24 for remaining rear wheels.
26. Using suitable lifting equipment, raise trailer frame
sufficiently to remove stands and blocking from the
axles, articulation pivot and trailer frame. Lower vehicle
to the ground and remove lifting equipment. Tighten all
wheel nuts to torque specified in Section 160-0050,
WHEEL RIM AND TYRE.
27. Remove wheel blocks from front road wheels and
place the steering lock bar in the 'Stowed' position.
28. Bleed all air from hydraulic brake lines. Refer to
Section 165-0010, BRAKE PARTS.

Every 250 Hours: Lubricate equalizer beam bushings
(21) through lube fittings (27) with grease specified in
Section 300-0020, LUBRICATION SYSTEM, until
excess lube is seen.
