3.
Drain the oil through the oil drain valve located at the base of the compressor and purge the
compressor until all pressure is relieved.
4.
Remove the compressor side cover (hand-hole cover) being careful to protect the gasket and
surface from damage.
5.
Inspect the crankcase inside for foreign material such as sludge, metal flakes, burrs, or anything
which may look unusual, indicating excessive wear or damage.
6.
Remove all remaining oil and wipe out the compressor with a lint-free cloth. The extent of
internal inspection should be dependent on the degree of evidence of wear.
7.
Inspect and clean the oil strainer. Cleaning can be accomplished with light oil, diesel fuel or
mineral spirits. Make sure excess cleaning agents are removed prior to closing the crankcase.
8.
Clean the oil sight glass and install the side cover plate using a new gasket if necessary and
torqueing bolts to the correct specification.
9.
Evacuate the compressor and add new oil to the crankcase.
10.Restore power to the crankcase heater allowing time to warm the oil.
11.Open the suction valve, discharge valve, oil return valve, and any other valves which may have
been closed for servicing and check for leaks.
12.Check and confirm sufficient oil pressure as you witness at least one complete cycle when
operation is resumed.
Belt Tension
. New belts should be checked after the first day running, after the first week for
tension, then at regular intervals for tension, alignment, and wear
1.
Always use matched sets or banded belts for multiple belt applications.
2.
Too much tension shortens belt life and motor bearing life.
3.
Never use a petroleum base belt dressing.
4.
The proper tension is just enough to prevent slipping.
Reasons for premature wear:
1.
Pulley misalignment
2.
Belts not matched
3.
Dirt or foreign material present
4.
Excessive slipping (loose tension)
Belt Replacement
. Belts which are worn, cracked, frayed, or over stretched should be replaced.
1.
Remove the belt guard and loosen motor hold-down bolts.
2.
Move the motor and sheave closer to the compressor until there is enough slack to remove the
old belts.
3.
Remove the old belts and clean the sheave grove if necessary with non-flammable, non-toxic
degreasing agent or commercial detergent.
4.
Install new belts by rotating the belt and sheaves to obtain seating in the grooves.
Note: on drives having more belt grooves in the sheaves than needed, use the grooves closest to
the motor and compressor. Make sure that the belts are all slack on the same side of the drive,
preferably the bottom, prior to tightening.
5.
Move the sheaves apart until the belts are snug.
