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

System<br />
12.If hydraulic fitting removal is needed, note orientation<br />
of hydraulic fittings before removing fittings from motor.<br />
Installation (Fig. 40)<br />
1. If removed, lubricate new O--rings and install hydraulic<br />
fittings to motor.<br />
