Description
What does a Piston & Liner Shim do?
This Piston & Liner Shim serves as a critical adjustment component within the engine assembly, specifically positioned between the cylinder liner and the engine block seating surface. By providing precise thickness, it allows technicians to achieve the exact liner protrusion required for proper cylinder head gasket clamping pressure. Maintaining correct protrusion is vital for preventing leaks and ensuring long-term engine sealing under high combustion pressures.Compatibility and engine fitment
This specific component is designed for Volvo applications, particularly within the TD100 engine series. It features an outside diameter of 146.10 mm and an inside diameter of 141.10 mm, with a thickness of 0.50 mm to meet strict OEM-standard fitment requirements for heavy-duty diesel engines.Installation and maintenance guidance
During engine overhauls or liner replacements, workshop technicians must measure the liner protrusion to select the correct shim grade. Using high-strength materials ensures that these shims resist crushing and maintain stability throughout the service life of the engine. Always verify dimensions before installation to ensure optimal compression and thermal management.Selection for engine overhauls
Selecting the correct shim is essential for maintaining fuel efficiency and preventing premature gasket failure in heavy commercial vehicle engines.OE cross-reference
