276-8134 10 Pieces Cylinder Head Bolts — Cat 1104D E44T

These are high-strength cylinder head bolts designed to secure the cylinder head to the engine block, crucial for maintaining compression and preventing leaks in the combustion chamber. Manufactured from premium steel alloys, they offer superior tensile strength and resistance to stretching compared to worn or damaged bolts. Operators may experience a loss of engine power, coolant leaks into the combustion chamber, or rough engine operation if these bolts fail.

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

Early signs of failing cylinder head bolts may include minor coolant loss or a slight drop in engine power. If ignored, the clamping force will diminish, leading to increased combustion gas leakage and potential coolant contamination. Continued operation risks severe engine damage due to loss of compression and overheating.

Installation Tip

Ensure the cylinder head and block surfaces are perfectly clean and flat before installation; even minor debris can compromise the seal. Always follow the manufacturer's specified torque sequence and values precisely.

Service Note

When replacing cylinder head bolts, it is essential to inspect the cylinder head gasket for signs of failure and replace it as well.
