WABCO 9122180020X Remanufactured Single-Piston Air Compressor

PACCAR MX-Series | Remanufactured by Turbo Kings

Precision Remanufacturing

This WABCO 9122180020X single-piston air compressor is remanufactured by Turbo Kings to exceed OE operating standards for PACCAR MX-series applications. Each unit begins with a complete teardown and inspection to identify microscopic wear patterns on the crankshaft journals, piston skirt, bore surface, delivery-valve seats, and governor-control passages. Components are measured with precision gauges, and any part that does not meet OE tolerances is replaced with new, premium-grade components.

Housings and cylinder blocks undergo an alkaline cleaning process followed by media finishing to restore proper sealing surfaces. The cylinder head receives resurfacing where required, with valve plates and delivery-valve seats restored to ensure consistent pressure retention and leak-free cycling. The piston assembly is rebuilt using new rings, new wrist-pin bushings, and a properly honed bore to maintain correct lubrication flow and compression balance. Every sealing interface is refitted with new gaskets and high-temperature O-rings, eliminating the blow-by problems commonly found in high-mileage cores.

Air System Reliability & Flow Efficiency

The 9122180020X compressor is designed to provide stable output for demanding PACCAR MX-13 duty cycles. Turbo Kings focuses heavily on optimizing crankcase sealing, discharge-valve response time, and head-plate flatness — three factors that directly influence air delivery stability and hot-idle performance. Each unit is set up to maintain consistent pressure under rapid load cycling, preventing over-cycling of the air dryer and premature wear of downstream pneumatic components.

Oil-control pathways are reconditioned to ensure proper lubrication delivery to the piston assembly and crankshaft. Worn drain-back channels are corrected to reduce oil carry-over into the air system, protecting service valves, brake chambers, and air-suspension components. The final unit is validated on a calibrated test bench to confirm idle efficiency, maximum output, recovery characteristics, and proper thermal stability during extended run cycles.

What Makes Turbo Kings Different

Turbo Kings remanufacturing goes beyond basic reseal procedures. Each compressor receives:

• Full dimensional inspection and corrective machining

• New piston rings, gaskets, valves, and seals

• Bore refinement for optimal compression

• Ultrasonic and alkaline cleaning for all internal passages

• Restored seat geometry on the valve plate

• Independent verification of oil-control characteristics

• Bench testing under controlled temperature and load simulations

Our goal is to deliver an air compressor that performs as reliably as an OE new unit while maintaining cost-efficient uptime for fleets and owner-operators.
