PULLEY ALIGNMENT -
Three examples of pulley misalignment are shown below. To check the pulley alignment, remove
the beltguard and place a straight edge against the pump flywheel. Measure the distance from the straight edge to the
motor pulley at several points. If the pulley needs to be adjusted, follow the procedure below.
1. Loosen the motor mounting bolts.
2. Loosen the setscrews on the motor pulley.
3. Align the motor pulley using the straight adge as a guide.
4. Retighten the motor pulley setscrew using thread-looking fluid.
5. Adjust the belt tension as described previously.
6. Retighten the motor mounting bolts.
7. Replace the belt guard and test.

Do not operate the compressor with any of its safety guards, shields, or screens removed.
Never cause the compressor to run at speeds in excess of the factory set RPM. Always follow
all safety precautions and warnings when performing service.
BELT TENSION -
Proper belt tension and pulley alignment must be maintained for maximum drive efficiency and belt life.
The correct tension exists if a deflection of 1/2
”
occurs by placing 10 pounds of force midway between the motor pulley and
the pump flywheel. See figure below. This deflection can be adjusted using the following procedure.
1. Remove belt guard.
2. Loosen the motor mounting bolts. Remove belts.
3. Shift the motor to the point where the correct tension
exists.
4. Retighten motor mounting bolts. Replace belts.
5. Check the tension again.
6. Replace the belt guard.
