„ COMPRESSOR PUMP OIL CHANGE
1. Remove the oil drain plug (A) and allow the lubricant to
drain into a suitable container.
2. Replace the oil drain plug.
3. Follow the filling procedures in OPERATION section.
„ BELT ADJUSTMENT

CHECKING BELT TENSION.

„
Check belt tension occasionally, especially if looseness is
suspected. New belts must also be properly tensioned upon
installation.
A quick check to determine if adjustment is proper may be
made by observing the slack side of the belt fora 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 or
engine anchor screws, pushing the motor or engine away
from the pump, and retightening the motor or engine anchor
screws. Some units are equipped with a belt tensioning bolt
that, when turned, pulls the motor or engine away from the
pump. Otherwise, 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.
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.

MAINTENANCE
2. At the center of the span, perpendicular to the belt,
Ensure the pulley and sheave are properly aligned and the
motor anchor screws are adequately retightened prior to
restarting the compressor.
A
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.
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
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 table.
