1300 02 047 VOLVO 0,50 mm Shim, Piston & Liner

The precision-engineered shim plays a critical role in maintaining the exact tolerances required within the piston and liner assembly of heavy-duty engines. This high-strength component is designed to ensure optimal mechanical alignment and performance under demanding operational conditions. By providing exact spacing, it helps maintain the structural integrity of the internal engine components during high-temperature cycles.

1300 02 047 is the OE-equivalent of the VOLVO 422621 shim used in the VOLVO TD100 engine system. This component is manufactured to match original specifications, ensuring seamless compatibility with the engine block and piston assembly. It is specifically designed to meet the rigorous standards of heavy commercial vehicle maintenance and engine rebuilding.

Workshop technicians should ensure that all surfaces are clean and free of debris before installation to maintain precise tolerances. Given its role in the engine's internal geometry, careful measurement of the thickness—exactly 0.50 mm—is essential during the assembly process to prevent improper clearances. Regular inspections of engine components during routine servicing can help identify if a replacement shim is necessary to maintain peak engine performance.
