The front spindle, brake and wheel hub assembly
weighs approximately 10,250 lbs. (4654 Kg). Be
certain lifting device is capable of lifting the load.
6. Position a fork lift under the wheel hub and spindle
assembly as shown in Figure 3-2. Use blocking
as necessary to prevent applying pressure to disc
brake housing when assembly is lowered from
suspension.
7. Remove capscrews and washers (1, Figure 3-3)
securing retainer plate (2) to spindle structure and
suspension. To prevent thread damage, loosen
capscrews in a circular pattern, in torque incre-
ments of 500 ft. lbs. (678 N.m). Remove retainer
plate.
NOTE: A tool may be fabricated locally to aid in spindle
removal. Refer to Tool Group, Section “M” for fabrica-
tion information. Usage of this tool is described below.
8. Remove 15 of the arm attachment capscrews (5)
as follows:
a. Refer to Figure 3-5 (spindle removal tool ) and
remove the capscrews in the spindle arm des-
ignated by an an “X”.
b. Remove the capscrews using a circular pattern
in torque increments of 500 ft. lbs. (678 N.m).
Do not attempt to remove each capscrew in
one sequence!
9. Run a tap (1.25" UNF) in the threads after cap-
screws are removed.
10. Using several 1.25" UNF x 8.00" long , grade 8
capscrews and hardened flatwashers (see Figure
3-4 for Komatsu part numbers), install the pusher
tool on the bottom of the steering arm.
NOTE: Multiple washers may be required to allow the
pusher capscrews to be effective. One or two washers
can be installed with the pusher tool in place to gauge
the washer height required to prevent capscrews from
bottoming out. The minimum recommended thread
engagement is 1.62 in. (41 mm).
