1) Lock out and tag out the electrical power supply.
2) Remove panels and guards to gain access to belt
drive area.
3) Release tension on belts by loosening locknut (1)
and backing off jackbolt (2). Remove existing belts
(and discard, if replacing).
4) Check sheaves for nicks, wear, and misalignment
before reinstalling belts.
5) Inspect new (or used) belts for defects or damage
before installation.
NOTICE!
If replacing belts, always replace with a factory
matched set of belts.
6) Install belts by rolling into position on the sheaves
and placing all the belt slack on the same side.
NOTICE!
If all slack is not brought to the same
side, the heavy starting load will be
borne by only some of the belts,
weakening or breaking the tensile
cords.
7) Rotate drive by hand to help seat
belts in sheaves. Check motor base,
it should be level within 5 degrees.
8) Tension the belts by turning the
jackbolt (2) clockwise until the
correct tension is set (reference table
on page 30).
9) Tighten jamnut (1) to lock the motor base in place.
Recheck belt tension and sheave alignment.
10) Reinstall any panels or guards which were
removed.
11) Start compressor and check for any obvious
problems.
12) Run the compressor for two hours to run-in the
belts. Immediately upon shutdown, check belt
temperature by hand.
NOTICE!
Heat buildup is an indication of misalignment. If
belts cannot be comfortably touched, refer to Belt
Drive Inspection Procedure on pages 29-30 and
correct alignment prior to operating unit.
13) Reset the belt tension to the after run-in tension
specification on page 30.
