This air compressor cylinder head is a vital component responsible for sealing the combustion chamber and directing air flow within the compressor unit for Volvo trucks. Manufactured to precise specifications, it ensures proper compression and heat dissipation, unlike a cracked or warped head. Operators may experience a significant loss of air pressure, a noisy compressor operation, or the compressor failing to build sufficient air for the braking system when this part is compromised.

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.
A failing cylinder head may initially manifest as a persistent air leak from the compressor unit or a noticeable decrease in air system pressure. If the issue progresses, the compressor may become excessively noisy, run hot, and fail to maintain adequate air pressure for safe braking. The ultimate risk is the inability to build sufficient air pressure, potentially leading to a loss of braking effectiveness.
Ensure the mating surfaces of the cylinder block and the new cylinder head are perfectly clean and flat before assembly. Use a new head gasket and torque the cylinder head bolts in the specified sequence and stages to prevent leaks and warping.
Always replace the cylinder head gasket when installing a new cylinder head, and inspect the valve plate for wear.
