4. Remove pulley from the taper lock bushing on the
piston pump:
A. Remove cap screws and lock washers securing
pulley to the taper lock bushing.
IMPORTANT: Excessive or unequal pressure on the
cap screws can break the bushing flange.
B. Insert cap screws into threaded removal holes of
the pulley. Tighten screws progressively and evenly
until the pulley is loose on the bushing. Remove
pulley from the bushing.
5. Remove pump lever and neutral arm assemblies
(Fig. 36) from the piston pump as follows:
CAUTION
The extension spring is under tension and may
cause personal injury during removal. Use cau-
tion when removing spring from the neutral arm.
A. Remove extension spring from the pump support
and neutral arm.
B. Disconnect traction control rod from the pump le-
ver by removing cap screw and lock nut.
C. Remove cap screw and washer securing the neu-
tral bracket to the piston pump. Remove flange nut
and carriage screw securing the neutral bracket to
the pump support.
D. Remove cap screw and flat washer securing the
pump lever to the piston pump trunnion.
E. Separate pump lever assembly from pump trun-
nion and neutral bracket assembly from pump sup-
port. Locate and remove key from pump trunnion.
6. Disconnect all hydraulic hoses connected to the hy-
draulic fittings on the piston and reel drive pumps. Allow
hoses to drain into a suitable container. Cap or plug
openings of pumps and hoses to prevent contamination.
CAUTION
Support piston and gear pumps when removing
them from the pump support to prevent them
from falling and causing personal injury.
7. Remove both cap screws, hardened washers, and
lock nuts securing the piston pump to the pump support.
Pull pump assembly from the machine.
Hydraulic System
8. Remove reel drive pump from the piston pump (see
Reel Drive Pump Removal).
9. Remove hydraulic fittings and O–rings from the
pumps as required.
10.If necessary, loosen socket head set screw in taper
lock bushing and remove bushing from the piston pump
shaft. Locate and remove key from piston pump shaft.
Piston Pump Installation (Fig. 35)
1. Make sure the inside of the taper lock bushing is
clean. Apply anti–seize lubricant to both the piston
pump shaft and the inside of the taper lock bushing.
Position key to pump shaft. Slide bushing onto shaft.
2. Apply medium strength thread–locking compound to
bushing socket head set screw. Secure taper lock bush-
ing to the marked position on the piston pump shaft with
set screw.
3. Remove caps and plugs that were placed during dis-
assembly from pumps. Install O–rings and hydraulic fit-
tings to their original positions on the piston and reel
drive pumps.
4. Install reel drive pump to piston pump (see Reel
Drive Pump Installation).
Support piston and gear pumps when installing
them to the pump support to prevent them from
falling and causing personal injury.
5. Position pump assembly to the pump support. Se-
cure piston pump to the pump support with both cap
screws, hardened washers, and lock nuts.
6. Remove plugs that were placed during disassembly
from hydraulic hoses. Connect all hydraulic hoses that
were removed during disassembly.
7. Install pump lever and neutral arm assemblies (Fig.
36) to the piston pump as follows:
A. Position neutral bracket assembly to the pump
and pump support. Secure neutral bracket to pump
with cap screw and washer. Secure neutral bracket
to pump support with carriage screw and flange nut.
B. Place key in pump trunnion and slide pump lever
assembly onto trunnion. Secure pump lever to the
trunnion with flat washer and cap screw.
C. Connect traction control rod to the pump lever
with cap screw and lock nut.
