5) Check compressor housing for casting or manufacturing deficiency (whether the oil return hole
is unblocked), repair or replaced the flawed housing.
(7) Air compressor overheating
Fault phenomenon: Air compressor exhaust temperature is too high; the running parts are hot.
Possible causes:
1) The relief valve or unloading valve isn’t working, which caused the compressor fail to take a
break.
2) Severe leakage in air brake system, which caused the compressor fail to take a break.
3) Insufficient oil supply to the running parts or scuffing.
Troubleshooting:
1) Check relief valve module when unloading intake, clean the jammed valve or replace valid
parts. Check unloading valve module when unloading exhaust, clean the jammed/blocked valve
or replace valid parts.
2) Check brake system, replace unserviceable parts.
3) Poor lubrication between piston and cylinder sleeve, undersized clearance or scuffing will
result in overheat, check and repair or replace unserviceable parts.
