REPLACING THE COMPRESSOR BELTS
When signs of damage (e.g., wear, tear, breakage, etc) appear on any belt, replace the complete set of
three (3) v-belts as follows:
1.
Disconnect, lockout and tagout the power supply to the starter
2.
Unlatch and remove the door panel opposite to the main cooling fan panel to gain access to the
v-belt system
– see Figure 1-3 page 10, for details.
3.
Remove the compressor shaft belt guard.
4.
Raise the motor to remove the belt set. This is accomplished by turning the jacking screw
clockwise (after loosening the jam nut) and raising the motor body until the v-belts can be
dismounted from the motor sheave.
5.
Replace the old belts with new ones. For proper belt life, use only genuine Gardner Denver
belts.
6.
Check the sheave alignment.
7.
Turn the jacking screw counter-clockwise to lower motor and transfer its weight unto the belt
set. Make sure that the belts remain aligned into each corresponding groove. Keep turning
jacking screw until it clears base frame surface by at least one inch and lock in place with
provided jam nut.
REPLACING THE SHEAVES
1.
Follow steps 1 through 4 given above to replace the compressor belts.
2.
Remove the belts.
3.
Carefully sketch or photograph the orientation of each sheave/bushing pair as they sit on their
respective shaft. You will need this information to re-install each pair.
4.
Loosen and remove the mounting screws securing the sheave to companion bushing. Install
the removed screws in the jack holes provided on the sheave and turn each in to pry the
bushing loose from the sheave. Remove the sheave and bushing from the shaft.
5.
When installing a new sheave / bushing pair, remove all protective grease from their surfaces.
6.
Insert the mounting screws into the sheave / bushing pair and lightly tighten them.
7.
Clean the shaft and mount the sheave / bushing pair. Align the motor sheave to the airend
sheave. When mounting the sheave / bushing pair, the bushing clamps to the shaft first, the
sheave can still be moved a little. This can affect the alignment of the sheaves.
8.
Tighten the mounting screws evenly.
9.
Tap the bushing lightly with a drift, and retighten the screws. REPEAT THIS PROCEDURE
SEVERAL TIMES TO MAKE SURE THE BUSHING AND SHEAVE ASSEMBLY IS TIGHT ON
THE SHAFT.
10.
Fill the holes in the bushing/sheave with grease to protect them from dirt and debris.
11.
Replace the old belts with new ones. For proper belt life, use only genuine Gardner Denver
belts.
12.
Check the sheave alignment - Refer to Sheave Set Alignment, page 50.
