Lubricant Specifications
(Use Quin-Cip lubricant.)
Ambient Temperature SAE Viscosity ISO Viscosity
Below 0°F SAE 5W ISO 22
0-32° F SAE 10W ISO 32
32-80°F SAE 20W ISO 68
60-104°F SAE 30 ISO 100
The lubricant selected must have a pour point at least 15° F
lower than the minimum expected ambient temperature .
Pulley / Sheave Alignment & Belt Tension
Improper pulley/sheave alignment and belt tension are causes for motor
overloading, excessive vibration, and premature belt and/or bearing failure. To
prevent this from happening, check the pulley/sheave alignment and belt
tension on a regular basis (refer to
SECTION 5, Maintenance Schedule ).
Periodically inspect the motor pulley(s) and compressor sheave(s) for oil,
grease, nicks or burrs. Clean or replace if necessary. Make sure they are
securely fastened. Align the compressor sheave with the motor or engine
pulley. Drive belt grooves of the pulley(s) and sheave(s) should be in line with
each other. The compressor crankshaft must be parallel to the motor or engine
drive shaft.
Belt tension should be measured and adjusted to provide smooth operation.
Step-by-step procedures are provided here to correctly measure and set the
drive belt tension:
Step 1) Measure the span length of the drive. (Refer to Fig. 5-1, Setting
Belt Tension .)
