Thrust Washer Set

The thrust washer set (Model TW610S) is a critical internal engine component engineered for General Motors Duramax diesel engines. These precision-machined washers manage axial (end-to-end) movement of the crankshaft, preventing harmful contact between rotating and stationary components that would otherwise accelerate wear and compromise engine reliability. For any mechanic rebuilding a Duramax or addressing crankshaft end-play issues, this OEM-equivalent kit from MAHLE ORIGINAL/CLEVITE represents the trusted choice for long-term durability.

Thrust washers work by creating a thin, controlled oil film between the crankshaft thrust surface and the engine block, reducing friction while maintaining precise clearances. The TW610S set features a nominal thickness of 0.106 inches, a specification critical to maintaining correct crankshaft end-play in Duramax applications. MAHLE ORIGINAL's manufacturing standards ensure uniform hardness, consistent surface finish, and exact dimensional tolerances—factors that directly impact how well these washers distribute loads and resist fatigue under the extreme pressures of diesel combustion. Using undersized or worn thrust washers allows excessive crankshaft movement, leading to timing gear noise, oil seal failure, and premature engine wear.

Engine builders, transmission rebuilders, and Duramax specialists rely on this kit during full engine overhauls or when addressing crankshaft play diagnosis. Proper installation requires careful alignment and clean engine internals to prevent debris from compromising the oil film. Technicians should always measure crankshaft end-play with a dial indicator before reassembly to confirm that washer selection matches the engine's requirements. For anyone investing in a Duramax rebuild or running high-output diesel power, OEM-spec thrust washers from MAHLE ORIGINAL/CLEVITE ensure the crankshaft operates within design parameters for thousands of reliable miles.
