3. Operate all hydraulic controls to relieve hydraulic
system pressure.
4. Remove traction cable ball joint from control plate on
piston pump by removing lock nut, cap screw and three
(3) flat washers from control plate (Fig. 49).
5. Disconnect wire harness connector from neutral
switch on piston pump (Fig. 50).
6. Remove flange head screw and flange nut that se-
cures R--clamp and right side brake cable to pump as-
sembly (Fig. 50).
7. Read the General Precautions for Removing and
Installing Hydraulic System Components at the begin-
ning of the Service and Repairs section of this chapter.
8. For assembly purposes, label hydraulic hoses to
show their correct position on the pump assembly.
9. Put a drain pan below the pump assembly. Remove
hydraulic hoses connected to piston and gear pumps.
Put plugs or caps on disconnected hydraulic hoses and
fittings to prevent contamination of the system.
CAUTION
Pump assembly weighs approximately 72
pounds (33 kg). Make sure that pump assembly
is well supported during removal.
10.Support the pump assembly to prevent it from falling.
Remove two (2) cap screws, lock washers and flat
washers that secure pump assembly to engine bell
housing.
11. Carefully separate pump assembly from engine and
lower it out of the machine.
12.If needed, separate gear pump from piston pump
(see Gear Pump Removal in this section).
13.If hydraulic fittings are to be removed from piston
pump, mark fitting orientation to allow correct assembly.
Remove fittings from pump and discard O--rings.
Installation (Fig. 48)
1. If gear pump was removed from piston pump, install
gear pump to piston pump (see Gear Pump Installation
in this section).
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 the General
Information section of this chapter).
