BELT ADJUSTMENT


• CHECKING BELT TENSION
Check belt tension occasionally, especially if looseness is suspected��
A quick check to determine if adjustment is proper may be made by
observing the slack side of the belt for a slight bow when the unit
is in operation�� If a slight bow is evident, the belt is usually adjusted
satisfactorily��
• TENSIONING BELTS
Belt tensioning can be achieved by loosening the motor anchor screws,
pushing the motor away from the pump, and retightening the motor
anchor screws�� The motor can be easily moved by placing a prying tool
beneath it�� A commercially available spreader or other belt tensioning
device can also be helpful should tensioning be necessary��
Follow the procedures outlined below to correctly set and measure belt
tension��
1�� Lay a straight edge across the top outer surface of the belt drive from
pulley to sheave��
2�� At the center of the span, perpendicular to the belt, apply pressure
to the outer surface of the belt with a tension gauge�� Force the belt
to the deflection indicated in the table below�� Compare the reading
on the tension gauge to the following table��

0��17
Ensure the pulley and sheave are properly aligned and the motor anchor
screws are adequately retightened prior to restarting the compressor��

CAUTION
Improper pulley/sheave alignment and belt tension can result in
motor overload, excessive vibration, and premature belt and/or
bearing failure��
To prevent these problems from occurring, ensure the pulley and
sheave are aligned and belt tension is satisfactory after installing
new belts or tensioning existing belts��

TANK INSPECTION


The life of an air receiver tank is dependent upon several factors including,
but not limited to, operating conditions, ambient environments, and
the level of maintenance�� The exact effect of these factors on tank
life is difficult to predict; therefore, Ingersoll Rand recommends that
you schedule a certified tank inspection within the first five years of
compressor service�� To arrange a tank inspection, contact the nearest IR Air
Center or distributor, or call 1-800-AIR SERV��
If the tank has not been inspected within the first 10 years of compressor
service, the receiver must be taken out of service until it has passed
inspection�� Tanks that fail to meet requirements must be replaced��
WARNING
Failure to replace a rusted air receiver tank could result in air
receiver tank rupture or explosion, which could cause substantial
property damage, severe personal injury, or death�� Never modify
or repair tank�� Obtain replacement from service center��
