Description
What does a valve adjusting shim do?
This precision-ground shim serves as a critical component within the engine valve train, specifically designed to maintain precise valve clearance in heavy commercial vehicle diesel engines. By adding exact thickness between the rocker arm and the valve, it ensures the valve seats fully during every cycle, which is essential for optimal compression and engine performance.Vehicle and engine compatibility
This specific 2.35 mm component is fitted to Volvo FH12 engines with the D12D engine code. It is an essential replacement part for workshop technicians maintaining heavy-duty truck engines where clearance must be set to strict manufacturer tolerances to prevent premature wear of the valve seating face.Installation and maintenance
During installation, it is vital to ensure the shim seat is clean and lightly lubricated to prevent scoring upon first start-up. Technicians should always measure each valve individually, as each cylinder may require a different grade to achieve the correct lash. Always verify all clearances after assembly before closing the valve cover.Troubleshooting and selection
Selecting the correct thickness is crucial to prevent compression loss or excessive mechanical noise in the engine.OE cross-reference
1300 05 008 (Valve Adjusting Shim Engine Valve) is the equivalent of the Volvo OE number. This part directly replaces Volvo OE number 1547974.Other OEMs

FAQ
What is the function of a valve adjusting shim?
A valve adjusting shim is a precision-ground spacer that brings valve clearance back to the manufacturer's specified tolerance in heavy commercial vehicle engines.
Which vehicles is this shim compatible with?
This 2.35 mm shim is designed specifically for Volvo FH12 models equipped with the D12D engine.
How can I know if a shim needs replacement?
Symptoms like compression loss, increased engine noise, or irregular idling often indicate that valve clearances have drifted out of spec.
Can I grind a used shim to adjust clearance?
No, you should never grind a shim as it removes the hardened layer; always install a new, ready-made shim of the correct grade.
What are the OE reference numbers of this part?
1300 05 008 directly replaces Volvo OE number 1547974.
