Structural Maintenance
Unit And Engine Mounting
Bolts
Periodically check and tighten all unit and engine
mounting bolts. Torque the unit mounting bolts to
60 ft-lb (81.3 N•m). Torque the engine mounting
bolts to 50 ft-lb (68 N•m).
Lift Points
The unit lifting points are noted below. Note that
three lift points must be used.
Figure 63: Lift Points
Unit Inspection
Inspect the unit during unit pretrip inspection and
scheduled maintenance inspections for loose or
broken wires or hardware, compressor oil leaks,
or other physical damage which might affect unit
performance and require repair or replacement of
parts.
Evaporator Coil
Clean the evaporator coil during scheduled
maintenance inspections by blowing compressed
air opposite normal air flow. Inspect the coil and
fins for damage and repair if necessary.
Condenser Coil
Clean the condenser coil during scheduled
maintenance inspections by blowing compressed
air from the back side of the coil out toward the
front of the unit (direction opposite normal air
flow). Inspect the coil and fins for damage and
repair if necessary.
Defrost Damper
Check the damper during scheduled maintenance
inspections for shaft wear, end play and sealing
against air flow.
Position the damper so that the air flow is stopped
top and bottom with the solenoid plunger
bottomed.
1. If the damper does not close completely:
a. Energize damper solenoid by placing a
jumper wire from 12 Vdc to No. 29 wire in
the evaporator harness.
b. If damper blade closes, proceed to step 2.
If not, proceed to step 1.c.
c. Remove the jumper wire, loosen the
evaporator outlet adjustment angle and
move so when energized, the damper will
close.
d. Retighten the adjustment angle and repeat
steps a. and b.
2. If the damper blade does not seal evenly along
full width of blade:
a. Loosen the damper bearing blocks.
b. Manually close the damper so the blade
makes contact at the top and bottom of the
funnel, the full width of the blade.
c. Retighten damper bearing blocks.
d. Lube bearing block and shaft with low
temperature grease (see Tool Catalog).
1. Check Mounting Bolts for Tightness
Figure 62: Check Bolts For Tightness
CAUTION: Air pressure should not be
high enough to damage coil fins.
