This is a precision-machined shim used to adjust clearances within engine components, such as valve trains or bearing assemblies. It is manufactured from hardened steel to meet strict dimensional tolerances, ensuring proper component spacing and preventing premature wear that occurs with a damaged or missing shim. Symptoms of an incorrect shim include abnormal engine noises like ticking or knocking, and a potential loss of engine power or performance.

Cross-reference part number with serial number before ordering to confirm fitment. Keep original parts until new ones are confirmed correct. Record part numbers replaced for future reference.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
An incorrect or worn shim can cause audible ticking or knocking noises from the engine, especially during operation. If not corrected, improper clearances can lead to increased wear on related components and a reduction in engine efficiency. The ultimate consequence is potential damage to critical engine parts due to excessive play or binding.
Always clean the mating surfaces thoroughly before installing a new shim to ensure a precise fit and prevent contamination. Avoid reusing old shims, as they may have compressed or deformed, leading to incorrect clearances.
When replacing shims, inspect the associated valve lifters, camshaft lobes, and bearing surfaces for signs of wear or damage.
