3. Start at the bottom edge of the pulley as per
Figure 6-15
. Continue to set the belt into the
proper groove on the compressor pulley
(inside belt to inside track; outside belt to
outside track as in
Figure 6-16
).
4. After the belt is seated into the compressor
pulley groove, hold the belt and the pulley
with the left hand (
Figure 6-15
), while
rotating the pulley in the direction shown. At
the same time, feed the belt upward with the
right hand as the pulley is turned.
The belt will slip into place once the left hand,
which is holding the belt, reaches near the
top of the compressor pulley.
6.5.7.8 RE-TENSIONING OR REPLACING THE
GENERATOR SERPENTINE BELT
The generator is driven by the engine using a serpentine
belt. This belt will generally not need replacement during
the service life of the generator system. However, over
time it 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.
The belt guard must be removed to access the drive belt.
The Air N Arc 200 Series All-In-One Power System
®
utilizes a single serpentine v-belt to drive the generator
system.
Consult Section 6.5.7.1, Accessing the Drive
Belts
, for instructions on how to remove the belt guard.
6.5.7.9 RE-TENSIONING THE GENERATOR
SERPENTINE DRIVE BELT
NOTE
Proper alignment of all pulleys on the
serpentine belt is crucial. A chirping or
squeaking sound after replacing the
belts may indicate an alignment problem.
Always inspect and replace the belts as
recommended in the maintenance
section of this manual.
