Troubleshooting Guide

SyMptoM
Excessive noise in
operation
Knock – same cycle as
RPM of pump
Knock occurs while
compressor is loading
Milky oil in oil reservoir
Excessive oil
consumption
Oil in discharge air
Compressor vibrates
Air blowing out of inlet
CauSe
1� Loose pulley, flywheel,
belt, belt guard, cooler,
clamps or accessories
2� Lack of oil in crankcase
3. Piston hitting the valve
plate
4� Compressor floor
mounting loose
5� Defective crankcase
6. Excessive crankcase end
play
1� Main bearings
2� Connecting rod bearings
3� Loose flywheel
1� Connecting rod bearings
2� Wrist pins, wrist pin
bearings
3� Loose connecting rod nut
Water entering oil reservoir
due to compressor
operating in high humidity
environment
1. Restricted air intake
2� Oil leaks
3� Worn piston rings
4� Wrong oil viscosity
5� Compressor tilted too
much
6� Scored cylinder
1� Compressor air intake
restricted
2� Worn piston rings
3. Excessive oil in
compressor
4� Wrong oil viscosity
1� Mounting bolts loose
2� Compressor not properly
mounted
3. Pulley and flywheel mis-
aligned
4. Belts loose or mismatched
5. Bent crankshaft
Broken inlet valve
Solution
1� Tighten�
2� Check for possible damage to bearings, replenish oil�
3. Remove the compressor cylinder head and inspect for foreign matter
on top of the piston. Replace with a new gasket and reassemble the
head�
4� Tighten�
5. Repair or replace.
6. Adjust and shim properly.
1. Replace bearings.
2. Replace rod.
3� Tighten�
1. Replace rod.
2. Replace complete piston assembly.
3� Tighten�
a. Pipe air intake to less humid air source.
b� Service unit (change oil, clean or replac�e air cleaner element, drain
tank) more often�
1� Clean or replace air filter�
2� Tighten bolts or replace gasket�
3. Replace rings.
4� Drain oil, refill with oil of proper viscosity� See "Lubrication" section�
5� Level compressor�
6. Replace cylinder and rings.
1� Clean air filter element and check for other restrictions in the intake
system�
2. Replace rings.
3� Drain down to proper level�
4� Check viscosity� See "Lubrication" section�
1� Tighten�
2� Level compressor so that all feet touch the floor before tightening
down� Use shims if necessary�
3. Realign.
4� Tighten belts� See "Maintenance" section�
5. Replace crankshaft.
Replace valve plate assembly.
