5� Blown gaskets
6� Low compression
1� Poor ventilation
2� Dirty cooling surfaces
1� Pulley out of alignment
2� Belt too loose or too tight
3� Belt slipping
4� Pulley wobbles
1� Low engine idle
2� Improper lubrication
3� Low oil level
4� Defective unloader valve
1� Loose engine or
compressor pulley
2� Lack of oil in crankcase
3� Worn connecting rod
4� Worn piston pin bushing
5� Worn bearings
6� Piston hitting the valve

7� Noisy check valve
Solution
1� 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�
2� Remove head and inspect for valve breakage, weak valves, scored
valve seats, etc� Replace defective parts and reassemble�
Be sure that the old head gasket is replaced with a new
one each time the head is removed.
3� Clean the air filter element�
4� Loosen engine clamping bolts and move the engine in a direction
away from the compressor, being sure that the engine pulley is
perfectly aligned with the flywheel� Tighten engine clamping bolts�
The belt should deflect about 1/2 inch under 5-lbs of force� Do not
"roll" belts over pulleys�
5� Replace any gaskets proven faulty on inspection�
6� Low pressure can be due to worn rings and cylinder walls� Correction
is made by replacing the rings, cylinders, and pistons as required�
1� Relocate the compressor to an area where an ample supply of cool,
clean, dry and well-circulated air is available�
2� Clean the cooling surfaces of pump and motor/engine�
1� Realign engine pulley with compressor pulley�
2� Adjust tension (See Drive Belt Section)�
3� Adjust tension or replace belt (See Drive Belt Section)�
4� Check for worn crankshaft, keyway or pulley bore resulting from
running the compressor or motor with loose pulleys� Check for bent
pulleys or bent crankshaft�
1� Increase idle, refer to engine manual for details�
2� See Lubrication Section�
3� Check oil level� Fill if necessary�
4� Replace�
1� Loose engine or compressor pulleys are a very common cause of
compressors knocking� Tighten pulley clamp bolts and set-screws�
2� Check for proper oil level; if low, check for possible damage to
bearings� Dirty oil can cause excessive wear�
3� Replace connecting rod�
4� Remove piston assemblies from the compressor and inspect for
excess wear� Replace excessively worn piston pin or pistons, as
required�
5� Replace worn bearings and change oil�
6� 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�
7� Replace�
