Troubleshooting Guide

SYMPTOM
Low discharge pressure
Overheating
Excessive belt wear
Unit stalls
Excessive noise
(knocking)
10 www.chpower.com
CAUSE
1. Air leaks
2. Leaking valves
3. Restricted air intake
4. Slipping belts
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
plate
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.
