This air compressor repair kit contains the necessary seals, gaskets, and small components to restore the functionality of the air compressor system on Volvo D12 engines. It is designed to replace worn or leaking parts, ensuring the compressor can effectively generate air pressure for the braking and auxiliary systems. Operators might notice a drop in air pressure, continuous compressor cycling, or air leaks around the compressor housing when this kit is needed.

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
Initial signs of a failing air compressor include a noticeable decrease in air pressure or the compressor running excessively to maintain pressure. If left unaddressed, this can lead to insufficient air for braking systems, potentially affecting vehicle safety. The compressor may also overheat, leading to internal damage and a complete loss of air supply.
Thoroughly clean all mating surfaces of the compressor housing before installing new seals to ensure a leak-free seal. Be careful not to pinch or twist any O-rings during assembly, as this will compromise their sealing ability.
Inspect the air dryer and air lines for moisture and oil contamination, as these can degrade compressor seals and lead to premature failure.
