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

Initial signs of worn shims include ticking noises from the valve train and a slight reduction in engine power. If left unaddressed, improper valve clearance can lead to increased wear on camshaft lobes and valve seats. Continued operation with incorrect clearances risks significant internal engine damage.

Installation Tip

Ensure all mating surfaces are meticulously clean before installing new shims to prevent premature wear. Avoid overtightening any adjustment screws, as this can damage the valve train components.

Service Note

Inspect valve springs and valve guides for wear when replacing shims.
