⚠️ Common Signs of Failure

• Slow air-pressure build-up
• Excessive oil in the air system
• Coolant or air leakage
• Knocking or gear-drive noise
• Compressor overheating
• Air pressure failing to reach governor cut-out

🛠️ Service Notes

• Before fitting, find out why the old one failed — a restricted or dirty oil feed, or a blocked oil return, will kill the replacement just as fast
• Check the drive gear, coupling or belt drive and its mating parts for wear, and set the drive up to the procedure in the workshop manual for your engine
• Fit new gaskets, O-rings and sealing washers on the mounting, oil and air connections, and make sure the oil feed and return lines are clean and clear before connecting them
• Clean or renew the air side downstream as required — a compressor that has been passing oil will have contaminated the delivery line, the dryer and the receiver, and that contamination will come back to bite the new unit
• Check the compressor's air inlet supply is clean, drain condensate from the receiver, and after fitting run the system up and confirm it builds and holds pressure, checking all joints for air and oil leaks
