Removal (Fig. 40)
1. Park machine on a level surface, stop engine, engage
parking brake, and remove key from the ignition
switch.
CAUTION
Rotate steering wheel and depress traction pedal
in both forward and reverse to relieve hydraulic
system pressure and to avoid injury from
pressurized hydraulic oil.
2. Operate all hydraulic controls to relieve hydraulic
system pressure.
3. Read the General Precautions for Removing and
Installing Hydraulic System Components at the beginning
of the Service and Repairs section of this chapter.
4. Remove flange head screw and flange nut that secure
front and rear guard plate. Remove four (4) flange
nuts that retain guard plates to pump mount bracket. Remove
guard plates from machine.
5. Label all hydraulic connections to ease reassembly.
Clean hydraulic hose ends prior to disconnecting the
hoses from hydraulic motor.
6. Disconnect hydraulic hoses from motor. Allow hoses
to drain into a suitable container.
7. Put caps or plugs on disconnected hoses and fittings
to prevent contamination.
8. Remove lock nuts, flat washers, cap screws, and
coupler spacers that secure rubber coupling to hydraulic
motor hub.
9. Remove two (2) flange head screws and flange nuts
that secure hydraulic motor to pump mount bracket.
10.Remove hydraulic motor from machine.
11.If needed, loosen set screws in hydraulic motor hub.
Pull hub from motor shaft. Locate and remove woodruff
key from motor shaft. Remove set screws from hub.
Clean threads of set screws and hub.
2. If motor hub was removed, apply antiseize lubricant
to motor shaft. Install woodruff key in shaft and slide hub
onto motor shaft.
3. Position motor on pump mounting bracket and install
flange head screws and flange nuts to motor and mounting
bracket. Leave fasteners loose.
4. Place coupling spacers into rubber coupling. Install
cap screws, flat washers, and lock nuts to secure rubber
coupling to motor hub. Make sure that cap screw
threads extend through lock nut.
5. If motor hub was removed, apply Loctite #242 (or
equivalent) to threads of motor hub set screws. Install
set screws into hub to secure hub to motor shaft.
6. Turn pump shaft by hand and position motor on
mounting bracket to best align the coupling assembly
between the pump shaft and the hydraulic motor shaft.
7. Secure motor to mounting bracket by tightening
flange head screws and flange nuts.
8. Lubricate new O--rings and install hydraulic hoses to
correct hydraulic fittings on motor.
9. Position front and rear guard plates to pump mount
bracket. Install and tighten flange head screw and
flange nut to guard plates. Install flange nuts to secure
guard plates to pump mount bracket.
10.Check fluid level in hydraulic oil reservoir and adjust
as required (see Operator’s Manual).
11.Properly fill hydraulic system (see Charge Hydraulic
System in the Service and Repairs section of this chapter).
12.Stop engine and check for hydraulic oil leaks. Check
hydraulic reservoir oil level.
