6. Disconnect both battery cables at the battery. Dis-
connect negative cable first and then positive cable (see
Battery Service in the Service and Repairs section of
Chapter 5 – Electrical System).
7. Remove muffler from the engine (see Muffler Re-
moval in this section).
8. Remove radiator from machine (see Radiator Re-
moval in this section). Remove fan shroud.
9. Label all electrical wires for assembly purposes. Dis-
connect electrical wires from engine:
A. Negative battery cable, wire harness ground and
fuel stop solenoid (Fig. 11).
B. Glow plug bus (Fig. 12).
C. High temperature warning switch and high tem-
perature shutdown switch (Fig. 13).
D. Starter motor, fusible link harness, alternator and
oil pressure switch.
10.Disconnect throttle cable from the throttle support
bracket and swivel on the speed control lever. Position
cable away from engine.
11. Disconnect fuel supply hose at injector pump (Fig.
11). Disconnect return fuel hose from front injector
nozzle (Fig. 12). Plug and position disconnected hoses
to prevent fuel leakage.
12.Note location of cable ties securing the wire harness
to engine. Remove cable ties.
13.Support transmission to prevent it from moving dur-
ing engine removal.
CAUTION
When removing engine assembly, make sure lift
or hoist can safely support 250 pounds (114 kg).
14.Attach a suitable lift or hoist to lift tabs on front and
rear of engine. Support engine with lift or hoist to prevent
engine from shifting or moving.
15.Remove two (2) flange head screws that secure fuel/
water separator bracket to engine. Remove bracket and
separator from engine.
16.Remove six (6) flange head screws and two (2) sock-
et head screws securing the flywheel housing to engine.
17.Remove lock nut, snubbing washer and cap screw
that secures each side of engine to the engine mounts
attached to the frame.
