radiator assembly, fuel lines, hydraulic lines, elec-
trical wire harness or other components while re-
moving the engine.
17.Slowly move the engine assembly away from the hy-
draulic pump assembly to a llow the pump input shaft to
slide out of the spring coupler on the engine flywheel.
Once the engine has cleared the pump input shaft, care-

Engine Installation (Fig. 15)
1. Make sure that all p arts 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 using Figure 15 or 20 as a guide.
3. Connect lift or hoist to the engine lift brackets.
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,
radiator assembly, fuel lines, hydraulic lines, elec-
trical wire harness or other components while
installing the engine.
4. Carefully lower engine into the machine. Slowly
move the engine assembly toward the hydraulic pump
assembly to allow the pump input shaft to slide into the
spring coupler on the engine flywheel.
5. Align engine to the engine mounts. Secure engine to
engine mounts with cap screws, rebound washers and
flange nuts.
6. Secure hydraulic pump assembly to engine (see
Pump Assembly in the Service and Repairs section of
Chapter 4 -- Hydraulic System).
7. On machines with a Tier 4 compliant engine (models
30606 and 30608):
A. Remove lift bracket from front of engine cylinder
head (item 6 in Fig. 17). The bracket must be re-
moved before fuel tank installation. Retain lift brack-
et and fasteners for future use.
B. Install and secure fuel tank to machine (see F uel
System in this section).
8. Position coolant reservoir with mount to the radiator.
Secure reservoir tank mount to the radiator and radiator
shrouds with removed fasteners.
9. Connect fuel supply and return hoses to the engine
fittings (Fig. 17 or 18).
10.On Groundsmaster 4110--D machines:
A. Install air conditioningcompressor to compressor
mount (see Air Conditioning Compressor Installation
in the Service and Repairs section ofChapter 9 -- Op-
erator Cab). Make sure that drive belt is properly ten-
sioned.
B. Connect coolant hoses to fittings on engine water
flange.
11.Connect wires and/or electrical connections to en-
gine locations.
A. The engine wire harness from the machine wire
harness.
B. The positive battery cable from the engine starter
motor (Fig. 16).
C. The fusible link harness from the main wire har-
ness (Fig. 16).
D. The negative battery cable at the engine block
(Fig. 16).
12.Carefully connect engine wire harness connector to
engine ECU.
13.Install and secure exhaust bracket (item 13 in Fig. 15
or item 6 in Fig. 20) and exhaust pipe ( item 16 in Fig. 15)
from engine.
