Cutting Deck Motor
Removal
1. Park machine on a level surface, lower cutting deck,
stop engine, engage parking brake and remove key
from the ignition switch.
2. Read the General Precautions for Removing and
Installing Hydraulic System Components at the begin-
ning of this section.
3. To prevent contamination ofhydraulic system during
motor removal, thoroughly clean exterior of motor and
fittings.
4. Disconnect hydraulic lines from deck motor. Put
caps or plugs on fittings and hoses to prevent contami-
nation. Label hydraulic lines for proper installation.
5. Remove two (2) flange head screws that secure hy-
draulic motor to motor mount (Fig. 78).
6. Carefully remove hydraulic motor from cutting deck
taking care not to damage spider hub attached to motor.
Locate and remove spider and mounting shim(s) (if
present) from the deck.
7. If required, remove spider hub from motor shaft.
Straighten tab washer and remove nut, spider and
woodruff key.
Installation
1. If spider hub was removed from motor shaft, thor-
oughly clean tapered surfaces of hub and shaft. Install
spider hub to motor shaft with tab washer and nut.
Torque nut from 27 to 33 ft--lb (37 to 45 N--m). Bend
small tab of washer into keyway and large tab against
nut.
2. Check for proper clearance between spider hub and
spindle pulley. Install motor to cutting deck without plac-
ing the spider in the spindle pulley. The clearance be-
tween hub and pulley valleys should be from 0.830” to
0.930” (21.1 to 23.6 mm). If required, use mounting
shims between motor and motor mount to adjust clea-
rance.
3. Position spider in spindle pulley. Place mounting
shim(s) (if required) on deck. Carefully install hydraulic
motor to the cutting deck taking care not to damage spi-
der hub attached to motor.
4. Securemotor to cutting deckwith two (2) flangehead
screws (Fig. 78).
IMPORTANT: For proper hydraulic hose routing,
make sure cutting deck is fully lowered before
installing hoses to deck motor.
5. Remove caps or plugs from fittings and hoses. Con-
nect hydraulic hoses to deck motor.
6. After assembly is completed, verify that hydraulic
hoses and fittings are not contacted by moving compo-
nents through full range of deck movement.
