5. Disconnect or remove hydraulic tubes from the desired wheel motor in the
order recommended
completely remove the hydraulic tube or loosen the opposite end of the
hydraulic tube to allow wheel motor removal. If removed, mark or tag the
tube positions for installation.
6. Put caps or plugs on disconnected hydraulic lines and fittings to prevent
contamination.
Note: Although the rear wheel motors are the same for left and right sides,
do not interchange them as they have be run−in for one direction and
inefficiencies will result if switched.
7. If both wheel motors are being removed, label motors left side or right side.
Make sure wheel motor is properly supported before removing the
mounting screws. The wheel motor assembly weighs approximately
68 kg (150 lb).
8. Remove eight (8) cap screws that secure front wheel motor to the machine
frame and remove the wheel motor.
9. If necessary, remove fittings from wheel motor and discard fitting O−rings.
(Figure 91)
Because of internal differences in front wheel motors, DO NOT
interchange front wheel motors on machine (i.e. do not put right side
motor on left side of machine). If necessary, use parts catalog and
part number on wheel motor to identify RH and LH motors.
1. If fittings were removed from wheel motor, lubricate and place new O−rings
onto fittings. Install fittings into motor ports and tighten fittings (see
the Hydraulic Fittings (SAE Straight Thread O-Ring Fittings) (page
2. Position wheel motor in frame and secure with eight (8) cap screws. Tighten
cap screws from 183 to 224 N·m (135 to 165 ft−lb).
