Mahle Clevite Engine Crankshaft Thrust Washer Part No: TW583S

For dependable heavy-duty rebuilding, the Mahle Clevite TW583S Engine Crankshaft Thrust Washer Set delivers OE-equivalent crank endplay control for Caterpillar 3400-family engines. Thrust washers are critical at the #1 main saddle, preventing excessive crankshaft axial movement during clutch engagement, torque converter loading, or gear thrust. TW583S washers are engineered with durable bearing surfaces and tight tolerance control to maintain an oil film, resist scoring, and protect crank journals under sustained load. Installing TW583S during overhaul helps prevent crank walk, stabilizes bottom-end geometry, and extends engine service life. Sold by Wofford Truck Parts.
