Installation (Fig. 46)
1. If gear pump was removed from piston pump, install
gear pump to piston pump (see Gear Pump Installation
in this chapter).
2. If fittings were removed from piston pump, lubricate
and place new O−rings onto fittings. Install fittings into
pump port openings using marks made during the re-
moval process to properly orientate fittings. Tighten fit-
tings (see Hydraulic Fitting Installation in this chapter).
3. Apply antiseize lubricant to piston pump shaft
splines.
CAUTION
Pump assembly weighs approximately 72
pounds (33 kg). Make sure that pump assembly
is well supported during installation.
4. Carefully raise pump assembly and position it to the
engine.
5. Align spline teeth and slide piston pump input shaft
into engine coupling. Support pump to prevent it from
shifting while installing two (2) cap screws, lock washers
and flat washers to secure pump to engine bell housing.
6. Secure traction cable to control plate with cap screw,
three (3) washers and lock nut (Fig. 47).
7. Connect wire harness connector to neutral switch on
piston pump (Fig. 48).
8. Remove plugs or caps from disconnected hydraulic
hoses and fittings on pumps. Lubricate new O−rings and
install hydraulic hoses to correct location on gear and
piston pumps (see Hydraulic Hose and Tube Installation
in the General Information section of this chapter).
9. Secure R−clamp and right side brake cable to pump
assembly with flange head screw and flange nut
(Fig. 48).
10.Charge the hydraulic system (see Charge Hydraulic
System in this chapter).
11.Adjust traction pedal to the neutral position (see Ad-
just Traction Pedal for Neutral in the Adjustments sec-
tion of this chapter).
12.Install the rear undercarriage shroud (see Undercar-
riage Shrouds in Chapter 9 − Chassis in this manual).
