Wheel Bearings (Front) -
Lubricate
(Two-Wheel Drive)
SMCS Code: 4205; 4208
Use the following procedure for both wheels.
1. Raise the front wheels slightly off the ground.
2. Install sufficient blocking under the frame and
lower the machine to the blocking.
3. Remove the nuts and both wheels.

4. Remove the hub cap (1).
5. Remove the cotter pin (2), nut (3), and washer
(4).
6. Pull the hub assembly (5) until the cone and
roller assembly come out of the hub assembly.
Then, pull off the hub all the way.
7. Clean all of the parts in clean, nonflammable
solvent and allow the parts to air dry. Do not
use pressure air.
8. Inspect the roller assemblies for heat
discoloration and for wear. Inspect the seals for
damage. Replace any damaged parts.
9. Make sure that the grease gets packed between
the rollers and the cage on both bearings.
Force the grease through the bearing from the
large end of the rollers.
10. Pack a 6 mm (0.25 inch) layer of grease
between the bearing assemblies in the hub. Do
not fully pack the hub with grease.
11. Apply a 6 mm (0.25 inch) thick film of grease
on the spindle surface.
12. Install the hub, the bearings, the washer, the nut
and the wheel.
13. While you turn the wheel, tighten the nut (3) until
a slight drag is noticed. Back off the nut to the
nearest slot and install the cotter pin.
14. All bearing surfaces must make contact. The
wheel should turn freely within 0.025 to 0.25 mm
(0.001 to 0.010 inch) end play.
15. Install the hub cap.
16. Tighten the lug nuts to a torque of 400 ± 40 N·m
(295 ± 30 lb ft).

Wheel Nut Torque - Check
SMCS Code: 4051; 4199; 4200
g00287728
Illustration 406
Check the torque on new wheels or repaired wheels
after every ten service hours until the specified
torque is maintained.
Put a drop of oil on all wheel studs on reassembly.
Torque the nuts to 400 ± 40 N·m (295 ± 30 lb ft).
Use a star pattern when you torque the nuts.
Check the nuts on all four wheels.
