TROUBLESHOOTING CHART
SYMPTOM
POSSIBLE CAUSE(S)
Low discharge pressure
1. Air demand exceeds pump capacity
2. Air leaks
3. Restricted air intake
4. Blown gaskets
5. Leaking or damaged valves
Pump overheating
1. Insulating gasket between filter and
causes air filter to melt
head is missing
2. Broken valves/blown gasket
Excessive noise
1. Loose motor or compressor pulley
(knocking)
2. Lack of oil in crankcase
3. Worn connecting rod
4. Worn piston pin bores
5. Piston hitting the valve plate

CORRECTIVE ACTION
1. Reduce air demand or use a compressor with more capacity.
2. Listen for escaping air. Apply soap solution to all fittings
and connections. Bubbles will appear at points of leakage.
Tighten or replace leaking fittings or connections.
3. Clean the air filter element.
4. Replace any gaskets proven faulty on inspection.
5. Remove head and inspect for valve breakage, misaligned
valves, damaged valve seats, etc. Replace defective parts and
reassemble.
Install a new head gasket each
time the head is removed.
1. Install gasket.
2. Replace valves or install new gasket.
1. Loose motor or compressor pulleys are a very common cause
of compressors knocking. Tighten pulley clamp bolts and
setscrews.
2. Check for proper oil level; if low, check for possible damage
to bearings. Dirty oil can cause excessive wear.
3. Replace connecting rod. Maintain oil level and change oil
more frequently.
4. Remove piston assemblies from the compressor and inspect
for excess wear. Replace excessively worn piston pin or
pistons, as required. Maintain oil level and change oil more
frequently.
5. Remove the compressor head and valve plate and inspect
for carbon deposits or other foreign matter on top of
piston. Replace head and valve plate using new gasket. See
Lubrication section for recommended oil.
6. Replace.
Do not disassemble check valve
with air pressure in tank.
1. Replace with new rings. Maintain oil level and change oil
more frequently.
2. Clean filter. Check for other restrictions in the intake system.
3. Drain down to full level.
4. Use Mobil 1
10W-30.
®
1. Drain tank more often. At least daily.
2. Add a filter to reduce the amount of water in the air line.
