6UZ1 Overhaul Kit Excavator Engine Repair Kit For Isuzu 6UZ1 Engine

Complete in-frame overhaul kit for the Isuzu 6UZ1 9.8L engine. Includes gasket set with seals, cylinder liners, pistons with pins and rings, rod bushings and main bearings. Fits CASE CX500D, Doosan DX490LC-3 and other 6UZ1 powered excavators. Matched by engine serial number.

The Isuzu 6UZ1 powers some of the largest machines in its class, from 50-tonne class excavators such as the CASE CX500D LC and Doosan DX490LC-3 to Isuzu Giga heavy trucks, and it runs for extremely long hours under full load. When oil consumption climbs and power fades, an in-frame overhaul with a complete kit is the proven way to bring the engine back, because it replaces every wear item that determines compression, oil control and bearing life in a single pass. The kit is matched by engine serial number, which is essential on the 6UZ1 with its electronic injection configuration. It turns a costly engine replacement into a predictable, cost-effective repair.
