212-4893 2124893 Crankshaft Thrust Washer Bearing for C7 Diesel Engine Excavator Construction Machinery Parts

The 212-4893 Crankshaft Thrust Washer is a replacement diesel engine bearing component offered for compatible C7 engine applications used in excavators and heavy construction machinery.

Also known as a Crankshaft Thrust Bearing, Engine Thrust Washer, or Thrust Bearing Washer, this component is designed to help control axial movement of the crankshaft within a compatible engine assembly.

During engine operation, the crankshaft may experience axial forces generated by mechanical and operating loads. The thrust washer provides a designated bearing surface to help limit excessive crankshaft end play and support proper crankshaft positioning.

The 212-4893 thrust washer features a semi-circular metal bearing structure, smooth inner bearing surface, and curved profile designed for installation in the corresponding engine crankshaft bearing arrangement.

This replacement component is suitable for compatible diesel engine rebuilding, crankshaft maintenance, engine bearing replacement, and construction machinery engine overhaul applications.

JISION supplies diesel engine bearings, thrust washers, crankshaft components, and construction machinery replacement parts to equipment owners, engine repair workshops, and international spare parts distributors.
