140-8454 Thick Steel Shim — Cat C27 C18

This is a thick steel shim used to maintain precise clearances within engine components, such as crankshaft or camshaft bearings. It ensures proper alignment and load distribution, critical for the longevity and efficient operation of the engine's rotating assembly. Wear or damage to a shim can result in increased bearing play, noise, and accelerated wear on related parts.

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

Increased engine noise, such as knocking or rattling from the bottom end, may indicate a worn shim or incorrect bearing clearance. If left unaddressed, this can lead to premature bearing failure and potential crankshaft damage. Continued operation risks severe internal engine damage.

Installation Tip

Ensure the shim surfaces are perfectly clean and free of any burrs or debris before installation. Do not reuse old shims, as they may have deformed.

Service Note

Inspect all related engine bearings for wear and measure journal clearances carefully when replacing shims.
