85104247 Cylinder Head for Volvo 8500

What does a compressor cylinder head do?

This cylinder head serves as the essential cast component that closes the top of the air brake compressor's cylinder block. It provides the critical seating for both inlet and discharge valves, ensuring that compressed air is contained and routed through the discharge port without leakage. By managing compression heat, this part plays a vital role in the longevity of the entire pneumatic system.

Vehicle compatibility and fitment

This specific part is compatible with Volvo 8500 models. It is engineered to meet OE dimensions, allowing technicians to rebuild the compressor in place rather than replacing the entire unit. This component is specifically intended for use in heavy commercial vehicle applications where reliable air pressure is mandatory.

Installation and maintenance

When installing this cylinder head, technicians should carefully inspect the valve seats and ensure all mounting surfaces are clean to prevent air leaks. Proper torque application on the cylinder head bolts is essential to maintain a consistent seal under high-pressure cycles. Regular inspection of the head and valve plates can prevent sudden system failures.

Troubleshooting air pressure issues

If you notice a drop in air pressure or visible oil carryover in the air lines, it may indicate a failure in the compressor's sealing components. Consult your authorized distributor.
