442 011 02 59 MERCEDES BENZ Piston & Liner Shim

This precision-engineered shim plays a vital role in the piston and liner assembly, ensuring the exact clearance required for optimal engine performance. Designed for high-stress environments, this component provides the necessary stability and dimensional accuracy required during engine rebuilding. It is manufactured using high-strength components to meet the rigorous demands of heavy commercial vehicle maintenance.

442 011 02 59 is the OE equivalent of the MERCEDES BENZ piston and liner shim used in MERCEDES BENZ heavy commercial vehicle engines. This specific part is essential for achieving precise tolerances within the cylinder assembly, maintaining the structural integrity of the engine system under heavy-duty operating conditions.

For workshop technicians, this shim offers reliable assembly ease due to its precise dimensions: a 153,50 mm outside diameter and a 146,90 mm inside diameter. Given its 0,40 mm thickness, it is a critical element in fine-tuning the piston clearance. Technicians should verify all measurements against the service manual to ensure perfect fitment within the engine block during overhaul processes.

Maintaining proper engine tolerances is essential for preventing premature wear in the piston and liner system. Regular inspections of these small but crucial components during major service intervals can help prevent larger mechanical failures in heavy commercial vehicle fleets.
