13.Disconnect fuel supply and return hoses from injec-
tion pump (item 16 and 17). Cap fuel hoses and injector
pump fittings to prevent contamination.
IMPORTANT: The hydraulic pump assembly can re-
main in machine during engine removal. To prevent
pump assembly from shifting or falling, make sure
to support pump assembly before piston (traction)
pump mounting fasteners are removed.
14.Support hydraulic pump assembly. Remove fasten-
ers that secure piston (traction) pump assembly to en-
gine (see Piston (Traction) Pump Assembly Removal in
Chapter 5 − Hydraulic System in this manual).
15.Make sure all cable ties securing the wire harness,
fuel lines and hydraulic hoses to the engine are re-
moved.
16.Connect lift or hoist to the lift brackets on engine.
17.Remove flange nuts, rebound washers and cap
screws that secure the engine mount brackets to the
rubber engine mounts (item 7).
CAUTION
One person should operate lift or hoist while a
second person guides the engine out of the ma-
chine.
IMPORTANT: Make sure to not damage the engine,
fuel lines, hydraulic lines, electrical harness or oth-
er parts while removing the engine.
18.Carefully move engine away from the hydraulic
pump assembly to disengage the pump input shaft from
the coupler on the engine flywheel. Once the engine has
cleared the hydraulic pump, carefully lift engine from the
machine.
19.If necessary, remove exhaust tailpipe (item 19) and
engine mount brackets from the engine.
Engine Installation (Fig. 13)
1. Make sure that all parts removed from the engine
during maintenance or rebuilding are installed to the en-
gine.
2. If removed, install engine mount brackets to the en-
gine.
3. Connect lift or hoist to the lift tabs on engine.
CAUTION
One person should operate lift or hoist while a
second person guides the engine into the ma-
chine.
IMPORTANT: Make sure to not damage the engine,
fuel lines, hydraulic lines, electrical harness or oth-
er parts while installing the engine.
4. Carefully lower engine into the machine. Move en-
gine toward the hydraulic pump assembly to engage the
pump input shaft with the coupler on the engine fly-
wheel.
5. Align engine mount brackets to the rubber engine
mounts (item 7).
Install tailpipe support and secure engine mount brack-
ets to rubber engine mounts with cap screws, rebound
washers and flange nuts.
6. Secure hydraulic pump assembly to engine (see Pis-
ton (Traction) Pump Assembly Installation in Chapter 5
− Hydraulic System in this manual).
7. Remove caps from fuel hose and injector pump fuel
inlet that were installed during engine removal to pre-
vent contamination. Connect fuel supply hose to injec-
tion pump. Secure hose with hose clamp.
8. Connect wire harness connectors to the following
engine components:
A. The two (2) engine wire harness connectors at
the engine ECU.
B. The engine wire harness connector at the ma-
chine wire harness located just rearward of the front
left engine mount.
C. The engine wire harness connectors at the start
relay, EGR relay, and the glow relay. The relays are
located on the air cleaner support bracket.
D. The positive battery cable and fusible link har-
ness at the engine starter motor.
E. The electric starter. Torque nut at starter B+ termi-
nal from 70 to 86 in − lb (7.9 to 9.7 N − m) .
F. The negative battery cable, engine wire harness
ground, and main wire harness ground wires. These
wires are secured with a cap screw and external lock
washer to the right side of the engine below the
starter motor.
