1.5 POWER PLANT ASSY. INSTALLATION
To install a power plant assembly, follow the
same procedure as in "Power Plant Assembly
Removal" except in reverse order, then proceed
with the following:
1. Torque the power plant cradle mounting
bolts to 190 lbf-ft (255 Nm).
2. Refill cooling system with saved fluid (refer
to Section 05
COOLANT SYSTEM
).
3. Once engine fuel system has been drained,
it will aid restarting if fuel filters are filled with
fuel oil (refer to Section 03
FUEL SYSTEM
).
4. Start engine for a visual check. Check fuel,
oil, cooling, pneumatic and hydraulic system
connections for leakage. Test operation of
engine controls and accessories.
1.6 ENGINE MOUNTS
The power plant assembly is mounted to the
cradle by means of rubber mounts and supports.
Two engine support brackets are used at the
front of the engine while two rubber mounts are
mounted underneath the engine & radiator fan
drive mechanism support and the engine &
alternator support (Fig. 10).
It is recommended that new rubber mounts be
installed at each major overhaul.
