This complete compressor cylinder head is a critical component for the air brake system on various Volvo truck models, responsible for sealing the combustion chamber and directing air flow. It is manufactured to precise Volvo specifications, ensuring optimal sealing and durability, unlike a cracked or warped head that compromises air pressure. Operators may notice a hissing sound from the compressor area, reduced air pressure build-up, or frequent compressor cycling when this part is failing.

Flush hydraulic lines before fitting new components. Use only manufacturer-specified hydraulic fluid. Check O-rings and backup rings for correct orientation. Bleed air from system after installation.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
Early signs of a failing compressor cylinder head include audible air leaks from the compressor assembly and a noticeable increase in the time it takes to build air pressure. If ignored, the air leaks will worsen, leading to insufficient air pressure for braking and other air-powered systems. The critical consequence is the potential for brake failure due to lack of air pressure, posing a severe safety risk.
Always use a new head gasket and ensure all mating surfaces are perfectly clean and free of old gasket material. Tighten the head bolts in the specified sequence and to the correct torque to ensure an even seal.
Inspect the compressor valves, piston rings, and cylinder bore for wear or damage.
