Remove the complete wheel and hub assembly and
extract the seal and inner bearing. Thoroughly clean all
parts in a suitable solvent and allow to dry.
WARNING : Do not use solvents in a confined
space. Work in a well ventilated area and avoid
skin contact with the solvent.
Inspect the bearings and both bearing cups in the wheel
hub for discoloration or wear. Repack the bearings and
the space between the two bearing cups with grease.
Grease the axle shaft.
Re-assemble and tighten the castellated nut to 25 lbf.
ft. (34 Nm). Rotate the wheel hub three to six revolutions
in a clockwise direction. Further tighten the castellated
nut to 50 lbf. ft. (68 Nm).
Now slacken the nut two slots. If the hole in the axle
shaft does not align with a slot in the nut, turn the nut in
a clockwise direction just sufficient to align the hole
with the nearest slot.
Install a new split pin and replace the hub cap.
Repeat the procedure on the other front wheel.
Operation 38 – Steering Box Oil Level
(Mechanical steering, where fitted)
Remove the steering gear cover (beneath the instrument
console) to gain access to the steering box.
Remove the filler/level plug and top up with clean oil,
as required. See Section C for correct oil grade.
LUBRICATION AND MAINTENANCE
14
Operation 39 – Starter Motor Pinion
Disconnect the cable from the battery earth terminal
and the battery cables from the starter motor and
solenoid. Extract the three securing bolts and remove
the starter motor.
Examine the starter pinion for clutch dust
contamination and, if necessary, brush clean with a
solution of 75% paraffin (kerosene) and 25% lubricating
oil. This mixture will provide sufficient lubrication for
the pinion until the next 600 hours service.
NOTE : This operation should be carried out more
frequently if the clutch is subject to heavy usage, such
as continuous loader operation.
Operation 40. Valve Tappet Clearance
Remove the valve rocker cover, taking care not to
damage the gasket.
Remove the plug from the flywheel access hole, Figure
34, and with the engine cold, place No. 1 (front) cylinder
on top dead center (TDC) of the firing stroke. (The arrow
on the casing will be aligned with the ‘0’ timing mark on
the flywheel).
