4.3 PUMP LUBRICANT

 

 

1.  Oil Level 

 

Always operate the unit in a level position.  Prior to start-up, check the sight glass to ensure the oil in 
the pump is at the required level.  If the oil level is too low, remove the oil fill plug and 

add oil until the 

level is at the center of the sight glass

.  For approximate oil requirements, see pages 16-17. Do not 

overfill or under fill as it could damage the pump.  

CAUTION!

 

The oil level in the pump crankcase 

must be checked daily

.  

 

2.  Oil Type 

 

The correct lubricant is essential to the proper operation of your compressor.  For single stage or 2-
stage compressors, use 

ISO 68, SAE 25 weight oil

.  This compressor oil is available at your local 

Princess Auto store.  

CAUTION!

 

Do not use motor oil in the compressor pump

.   

 

3.  Condensation 

 

Water condensing in the crankcase can occur under certain humid conditions or light duty cycling.  
This water must be removed from the pump to prevent damage.  Drain the oil and refill. 
 
Condensation can be prevented by allowing the pump to reach its normal operating temperature by 
releasing air from the tank and allowing the pump to run, or by using more air, which will cause the 
pump to operate more frequently.  

CAUTION!

 

A rise in the oil level and a milky color indicates that 

condensation is forming in the crankcase

.  This condensation must be drained immediately or the 

pump may be damaged. 

 

 

 
4.4 PULLEY ALIGNMENT & BELT TENSION 

 
Improper pulley alignment and belt tension are causes for motor overloading, excessive vibration and 
premature belt or bearing failure.  To prevent this from happening, check the pulley alignment and belt tension 
on a regular basis. 
 
Periodically, inspect both the motor and compressor pulleys for oil, grease, nicks or burrs.  Clean or replace 
pulleys if necessary.  Make sure the pulleys are securely fastened.  Align the compressor pulley with motor.  
The drive belt grooves of both pulleys should be in line with each other.  The compressor crankshaft must be 
parallel to the motor shaft. 
 

WARNING!

 

To avoid personal injury, always shut off main power disconnects for the compressor and 

relieve all air pressure from the system before performing any service on the air compressor

 

1.  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 (see A in Figure 3 on the next page) of ½” (13 mm) 
occurs by placing 10 lb (4.4 kg) of force (see B in Figure 3 on the next page) midway between the 
motor pulley and the pump flywheel.  This deflection can be adjusted by the following procedure.  The 
pulley should be carefully aligned with the flywheel and all setscrews should be kept tight.
