Corrective Action - Kobalt VT6389 Manual De Instrucciones

TROUBLESHOOTING
PROBLEM
Low discharge
pressure
(Continued)
Excessive noise
(knocking)
Large quantity of oil
in the discharge air
NOTE: In an oil-
lubed compressor
there will always be
a small amount of
oil in the air stream.
POSSIBLE CAUSE
4. Blown gaskets
5. Leaking or damaged
valves
1. Loose motor pulley or
flywheel
2. Loose fasteners on pump
or motor
3. Lack of oil in crankcase
4. Worn connecting rod
5. Worn piston pin bores
6. Piston hitting the valve
plate
7. Noisy check valve in
compressor system
1. Worn piston rings
2. Compressor air intake
restricted
3. Excessive oil in
compressor
4. Wrong oil viscosity

CORRECTIVE ACTION

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.
CAUTION
Unit care and maintenance. Install a new
head gasket each time the head is removed.
1. Tighten pulley / flywheel clamp bolts and set-
screws.
2. Tighten fasteners.
3. Check for proper oil level; if low, check for
possible damage to bearings. Dirty oil can
cause excessive wear.
4. Replace connecting rod. Maintain oil level and
change oil more frequently.
5. 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.
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. See Lubrication
section for recommended oil.
7. Replace check valve.
DANGER
Risk of Explosion. 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 or replace filter. Check for other
restrictions in the intake system.
3. Drain down to full level.
4. Use Mobil 1 10W-30 or full synthetic.
