## 📋 Kit Contents

-   AIR COMPRESSOR PISTON KIT

## 🔌 Function

The engine-driven compressor supplies pressurised air to the vehicle or machine air system. The repair kit restores compression, sealing, oil control or valve operation in the serviced compressor section.

## ⚠️ Common Signs of Failure

-   Slow air-pressure build-up or insufficient system pressure
-   Excessive oil carried into the air system
-   Air leakage, overheating or abnormal compressor noise
-   Compressor cycles continuously or cannot unload correctly
-   Scored pistons, damaged valves, failed gaskets or cracked cylinder-head components

## 🛠️ Service Notes

-   Confirm the kit is the one for your unit before starting, and lay the contents out against the parts you remove so nothing is left in the packet
-   Replace every seal, gasket and wearing part the kit supplies, even where the old one still looks serviceable — mixing old and new sealing parts in one joint is the usual reason a repair leaks again
-   Work clean and cap open pipes and ports; most repair kits serve fuel, oil, cooling or hydraulic components where dirt does the damage
-   Check what the kit does not include — bores, sealing faces, threads and shafts — because a kit cannot compensate for a worn housing
-   Assemble in the order and to the tightening figures given in the workshop manual for your engine, then test for leaks and correct operation before returning the engine to service
