71.1.1.2 Installation – Power Plant
This procedure applies to engine built up with
adapting parts to constitute a quick change
assembly.
71.1.1.2.1
Erect suitable engine hoist.
Attach cables of suitable engine sling on bolts or
pins inserted through eye on inlet housing and
bracket on diffuser section. Attach hoist to sling
and lift engine to horizontal position above
mounts.
NOTE
Check trunnion mount bearings prior to
installation for 0.010 inch maximum axial play
and 0.004 inch maximum radial play between ball
and race. If bearing play is greater than these
values, replace bearings.
71.1.1.2.2
Check that air intake bellmouth is
free to shift in slip joint of forward firewall to align
with engine inlet flange. If necessary, loosen
screws through firewall around bellmouth. Guide
engine nose into bellmouth while lowering engine
until trunnion bearings rest on pillow blocks (2,
Figure 71-1).
71.1.1.2.3
Position forward support tube (6)
rod-end, against mount trunnion fitting at left side
of inlet housing. Install retaining bolt and washer.
Lockwire bolt of trunnion. Close bearing caps of
mount pillow blocks, and tighten nuts on latching
eyebolts.
71.1.1.2.4
Secure upper section of rear
firewall to lower section with cowl fasteners.
71.1.1.2.5
Place V-band coupling clamp
over mating flanges of air intake bellmouth and
engine inlet housing. Tap around clamp to seat
while latching and tightening. Torque nut 40 to
50 inch-pounds, and lockwire. If loosened,
retighten screws in firewall around bellmouth.
Install beam and cowl halves with pip-pins,
between tops of forward and rear firewalls.
NOTE
Ensure large gap in “V” band clamp is located at
the 6:00 position to allow for drainage. The latch
and bolt are located at the 3:00 position. Refer
to Figure 72-2 (4).
71.1.1.2.6 Check
engine-to-transmission
alignment, if required. (Refer to paragraph
71.1.1.3).
71.1.1.2.7
Install main driveshaft between
engine and transmission and reinstall access
sections of intake screen and baffle. (Refer to
Chapter 63).
71.1.1.2.8
Connect engine hoses as
follows:
NOTE
To avoid improper installation of engine hose
assemblies, adhere strictly to the procedures
outlined below.
71.1.1.2.8.1 Fuel
control inlet hose (7, Figure
71-1) to maintain strainer outlet coupling.
Position shroud over connection and secure with
clamp.
71.1.1.2.8.2
Fuel control seal drain and
combustion drain hose to deck coupling below
left mount trunnion. Starter drive seal drain
hose (11) to deck coupling forward of fuel
control seal drain coupling.
71.1.1.2.8.3
Governor bleed hose to deck
coupling inboard of fuel strainer. Position
shroud over connection and secure with clamp.
71.1.1.2.8.4
Oil pump outlet hose (9) to
coupling on left side of filter. Position shroud
over connection and secure with clamp.
71.1.1.2.8.5
Oil pump inlet hose to oil tank
lower coupling and engine breather hose to oil
tank upper coupling.
71.1.1.2.8.6
Exhaust tailpipe drain hose to
coupling behind rear firewall.
NOTE
Prior to installation of bleed air hoses apply dry
film lube (C-005) to fitting threads.
