Removal (Fig. 26)<br />
1. Park machine on a level surface, stop engine, engage<br />
parking brake, and remove key from the ignition<br />
switch.<br />
2. To prevent contamination of hydraulic system during<br />
gear pump removal, thoroughly clean exterior of pump<br />
assembly.<br />
4. Install new hydraulic oil filter and fill hydraulic reservoir<br />
with correct oil (see Operator’s Manual).<br />
5. <strong>Pro</strong>perly fill hydraulic system (see Charge Hydraulic<br />
System in the Service and Repairs section of this chapter).<br />
6. Stop engine and check for hydraulic oil leaks. Check<br />
hydraulic reservoir oil level.<br />
CAUTION<br />
2<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 />
3. Operate all hydraulic controls to relieve hydraulic<br />
system pressure.<br />
4. 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 />
NOTE: To ease reassembly, tag hydraulic hoses to<br />
show their correct position on the gear pump.<br />
5. Put drain pan below the gear pump. Remove hydraulic<br />
hoses and fittings connected to gear pump. Put plugs<br />
or caps on disconnected hydraulic hoses and open<br />
ports of pump to prevent contamination of the system.<br />
6. Support the gear pump to prevent it from falling (Fig.<br />
27). Remove two (2) cap screws and flat washers retaining<br />
gear pump to piston pump.<br />
7. Carefully pull gear pump from piston pump and lower<br />
it out of the machine. Locate and retrieve o–ring from between<br />
pumps.<br />
Installation (Fig. 26)<br />
1. Lubricate new o–ring and position it to gear pump.<br />
Carefully raise gear pump and position it to the piston<br />
pump.<br />
2. Align spline teeth and slide gear pump input shaft<br />
into piston pump coupling. Support gear pump to prevent<br />
it from falling while installing two (2) cap screws and<br />
flat washers securing gear pump to piston pump.<br />
3. Remove plugs or caps from disconnected hydraulic<br />
hoses and ports of the gear pump. Lubricate new o–<br />
rings and install fittings and hoses to correct location on<br />
gear pump.<br />
