Precision Remanufacturing Backed by Real Testing
At Turbo Kings, every WABCO 9124120290X air compressor is rebuilt through a controlled, OEM-grade process that restores factory performance, reliability, and verified output.
Originally manufactured by WABCO for Volvo D11 and D13 engines between 2008 and 2016, this single-cylinder, water-cooled, gear-driven compressor delivers the steady air volume required for braking, suspension, and auxiliary systems across Volvo VNL, VHD, and VAH platforms.
Rated at approximately 15.5 CFM @ 1250 RPM, it uses a heavy-duty cast-iron crankcase for durability and a precision-machined aluminum head for efficient heat transfer—ensuring consistent pressure even in long-haul and vocational applications.
Each core that enters Turbo Kings is completely disassembled, cleaned, and dimensionally inspected. Crank journals, piston bores, and valve seats are measured for taper, scoring, and wear before being resurfaced within strict WABCO tolerances. Every wear component—rings, bearings, gaskets, and valves—is replaced with OEM-grade parts that restore original compression balance and efficiency.
All air and coolant passages undergo ultrasonic cleaning, removing internal scale, carbon, and oil residue that conventional washing can’t reach. This guarantees unrestricted flow and balanced thermal performance through every duty cycle.
After reassembly, each compressor is bench-tested under simulated engine load, validating pressure build rate, cut-in/cut-out accuracy, oil carry-over, and leak integrity. Only compressors meeting or exceeding WABCO and Volvo flow standards are serialized, logged, and cleared for shipment.
