Doosan D1146 Engine Overhaul Kit OE 65.03901-0092 for DX420LC/DX480LC Excavator

This Doosan D1146 Excavator Engine Overhaul Kit (Core OE No. 65.03901-0092 / 65.99601-8092) is a professional all-in-one rebuild solution engineered exclusively for Doosan D1146 inline 6-cylinder turbocharged diesel engines — the high-torque power core for 40-50 ton class excavators and large wheel loaders.
