3. After making your adjustments, position and
re-fasten the cover to the pressure switch
body with the cover retaining screw.
4. Close the hood, and cycle the compressor
several times to ensure the correct
pressures are set.
5. If additional adjustments are needed, repeat
steps one through four until the correct
pressures are set.
6.6.14 REPLACING AND RE-TENSIONING THE
SERPENTINE DRIVE BELTS
The compressor and generator are driven by the motor
using two belts. You may find that over time they become
loose and need to be tightened. The proper tension can
be determined by using a tension tester to measure the
deflection from a given force.
6.6.14.1 RE-TENSIONING THE AIR COMPRESSOR
SERPENTINE DRIVE BELT
Consult
Figure 6-16
, and the following procedure.
1. With the machine off and the ignition key
removed, open and remove the front panel.
2. Loosen the four tensioner plate bolts [
A
]
mounting the tensioner plate [
C
] to the
compressor only enough to allow tensioner
plate to rotate/slide along the grooves in the
plate while still in position (
DO NOT
remove).
3. Use a 1/2” drive torque wrench applied to the
square tensioning hole [
D
] to manually rotate
the plate/idler about the loosened, but
anchored, mounting bolt. Apply torque of 51
ft-lbs.
4. Once a position is achieved that accounts for
a satisfactory tension in the belt, torque the
four (4) tensioner plate bolts [
A
] to 12 ft-lbs
(16.3 Nm) to secure the tensioner into
position.

NOTE
Vanair
®
recommends that the air
compressor and generator serpentine
belts both be changed at the same time
even if only one of the belts is in need of
being changed.
NOTE
Proper alignment of all pulleys on the
serpentine belt is crucial. A chirping or
squeaking sound, noticeable after
replacing the belts, may indicate an
alignment problem. Always inspect and
replace the belts as recommended in the
maintenance section of this manual.
Misalignment of the v-belts can cause
unnecessary jumping and wear of the
belt, resulting in the belt coming off.
WARNING
Never operate the machine with the
access door removed.
NOTE
If new belts are installed, recheck the
tension after 10-20 hours of operation,
and adjust if necessary.
