17504542s5658 Head Bolt Washer Hard — Cat C10

This hard washer is designed to be used with head bolts, providing a stable and even load distribution across the cylinder head surface during tightening. Manufactured from high-strength steel, it offers superior durability and resistance to deformation compared to a worn or damaged washer that can cause uneven clamping force. Operators might notice coolant or combustion gas leaks around the cylinder head, or a drop in compression if this washer fails to maintain proper bolt tension.

Installation & Application Notes

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.

Failure Symptoms

Visible signs of leakage, such as oil or coolant seeping from the cylinder head gasket area, can indicate a problem with the head bolt washers. If the issue persists, combustion gases may enter the cooling system, causing overheating, or coolant may enter the cylinders, leading to white smoke. Failure to address this can result in severe engine damage due to loss of compression and internal contamination.

Installation Tip

Ensure the cylinder head and block surfaces are perfectly clean and flat before installing the head bolts and washers. Always use new head bolts and washers when reassembling a cylinder head.

Service Note

When replacing head bolt washers, it is essential to inspect the cylinder head gasket for signs of damage or blow-by.
