7-16. INSTALLATION OF ENGINE.
a. Attach a
one-half ton (minimum)
hoist to the
engine hoisting straps
and swing the
engine into alignment with
its attaching points on
the mount.
b. Insert an
engine mount
bolt through
the
hole of a mount
attachment
point
(a
washer is installed
next to the
head of the bolt)
and slide a half
of the shock mount
assembly
on the bolt.
Repeat this
procedure
for the other
three attachment
points.
c.
Position the
mounting lugs
of the engine
so that
they align
with the engine
mount
attaching points,
then move
the engine rearward
onto
the mounts.
d. Slide onto each mounting bolt a spacer washer (on serial numbers 32-570 and up),
spacer and
the forward half
of mount. Install washer
and nut and
torque nuts of bolts
to
450 to
500 inch-pounds.
e.
Reconnect all

for
information on pre-oiling
the engine to prevent a possible
high speed
bearing
failure.
7-17. INSTALLATION OF OIL COOLER.
a. When installing fittings in the oil coolers, care should be used to prevent excessive
torque being applied to the cooler. Where a rectangular fitting boss is provided, a back-up
wrench should
be used, employing a scissor motion,
so that no load is transmitted to
the
cooler. When the oil cooler has a
round fitting boss, care should be taken
not to permit
excessive torque on the fittings.
b. If a pipe thread fitting is used,
it should be installed only far enough
to seal with
sealing compound.
c. Apply Lubon No. 404 to all male pipe thread fittings; do not allow sealant to enter
the system.
d. If fitting cannot be positioned correctly as shown in Figure 7-4, using a torque of 10
to 15 foot-pounds, another fitting should be used.
e. When attaching lines to
the cooler, a back-up wrench should
be used.
f. After installation, inspect the cooler for distorted end cups.
g. Run-up engine. After run-up, check for oil leaks.
