5.5.2 REPLACING AND RE-TENSIONING
THE COMPRESSOR AND/OR
GENERATOR DRIVE BELTS
Relieve pressure from the compressor
system before performing maintenance
on any components.
Before performing maintenance or repair
operations on the machine, ensure that
all power has been removed and locked
out to prevent accidental start-up.
The engine drives the compressor and the
generators via the use of two drive belt
types. The compressor utilizes a poly-link,
chain-type belt, whereas the generators are
driven by a serpentine v-belt. The belts will
generally not need replacement during the
service life of the system. However, over
time they become loose and need to be
tightened. Consult Section
instruction on how to check the compressor
belt(s) tension.

amount of links in the belt. Proper tension on
a poly link v-belt is 3/8" to 1/2" give. Consult
