This is a precision-engineered shim used within the engine of Volvo FH12 and FH16 series trucks, crucial for maintaining correct clearances in critical engine components like bearings or camshafts. Manufactured to exact OEM tolerances, it ensures proper lubrication and load distribution, unlike worn shims that can lead to excessive play. Operators may notice increased engine noise, oil pressure fluctuations, or reduced engine performance if a shim fails or is missing.

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.
A worn or missing shim may initially manifest as an audible ticking or knocking sound from the engine, particularly at idle or under load. If not corrected, this can lead to increased friction, accelerated wear on adjacent components, and potential loss of oil pressure. The primary risk is severe internal engine damage due to improper component clearances.
Always use new shims when adjusting clearances and ensure they are seated correctly without any burrs or damage. Reassemble components carefully to avoid dislodging the shim during installation.
When replacing shims, it is critical to inspect the associated components (e.g., bearings, camshaft journals) for wear or damage.
