Belt Information

 

 

 

 

 

 

 

CAUTION
Do not dislodge balancing clips. Check set screw for tightness

  • Belt Tension and Pulley Alignment
Excessive belt tension is the number 1 cause of blower bearing failure.
 
Proper belt tension and pulley alignment are essential for trouble free operation.
 
A simple "Rule of Thumb" for checking belt tension is illustrated. 
When the belt is grasped as shown a total deflection of approximately 1" should be easily attained.
 
Insufficient deflection indicates that the belt is too tight, resulting in noise from excessive vibration, premature bearing failure and short belt life. Tight belts may overload a motor that would otherwise be adequate.
 
Excessive deflection is an indication that the belt is not tight enough. If not corrected, slippage could cause a loss of blower speed and belt failure through wear.
 
A belt should be just tight enough to avoid slippage.
 
Align pulleys with a straight edge to conserve belt life and eliminate unnecessary noise.
 
Check tension before start-up, after every pulley adjustment and regularly thereafter.
 
Set Screws:
Ensure all set screws on both pulleys and the blower wheel are tight.
 
  • Lubrication
Re-lubrication is unnecessary under most operating conditions. If re-lubrication is required, lubricant should be compatible to Esso Beacon #325
 

  • V-Belt Drives
Proper belt tension and alignment is essential for quiet opertation and bearing life. Follow illustrated recommendations on belt installation below.
 
  • Maintenance
Inspect periodically for mountain rigidity. Verify belt for wear and tension and adjust as required. Inspect wheel for any dust accumulation and clean as indicated.
