Installation
1. Clean spindle bore and suspension rod taper to
be certain they are free of rust, dirt, etc.
2. Lubricate spindle bore and suspension rod taper
with multi-purpose grease Number 2 with 5%
Molybdenum Disulphide.
3. Position spindle and wheel hub assembly on fork
lift or similar lifting device as shown in Figure 3-2.
4. Raise the spindle and wheel hub assembly into
position.
5. Secure spindle to suspension using retainer plate
(2, Figure 3-3) and capscrews (1). Tighten cap-
screws using the following procedure:
a. Tighten capscrews uniformly to 500 ft. lbs.
(678 N.m) torque.
b. Continue to tighten capscrews in increments of
250 ft. lbs. (339 N.m) to obtain a final torque
of 1995 ±100 ft. lbs. (2705 ±135 N.m).
6. If removed, install spindle arm. Tighten capscrews
to 1995 ±100 ft. lbs. (2705 ±135 N.m) torque.
7. Install steering cylinder into steering arm. Use
EH4638 sleeve alignment tool (included in tool
group) to position spacers and bearing during pin
insertion. Tighten pin retaining nut to 750 ft. lbs.
(1017 N.m) torque.
8. Install tie rod on steering arm using EH4638
alignment tool. Tighten pin retaining nut to 750 ft.
lbs. (1017 N.m) torque.
9. Connect lubrication lines.
10. Install brake system cooling hoses using new
O-rings in the flange fittings. Install brake apply
line. Be certain drain plug (2, Figure 3-1) is in-
stalled.
11. Reconnect speed sensor cables.
12. Install wheel and tire as described in “Front Wheel
and Tire Installation”.
13. Be certain hydraulic pump shut-off valves are
open.
14. Start the engine. With the hoist control lever in the
float position, allow hydraulic oil to circulate
through the brake cooling system, allowing the
front wheel hub and disc brake assembly to fill with
oil.
15. Bleed air from brake apply line as described in
Section “J”, Wet Disc Brake Assembly, Brake
Bleeding Procedure.
16. Shut down the engine. Check hydraulic tank oil
level and refill if necessary. Inspect brake assem-
bly and hose connections for leaks.
