Doosan D2366/D2366T Overhaul Kit OE 65.06500-6125 for Doosan Excavator Engine Parts
This Doosan D2366 Excavator Engine Overhaul Kit (Core OE No. 65.03901-0076 / 65.06500-6125) is a professional heavy-duty rebuild solution engineered exclusively for Doosan D2366 / D2366T inline 6-cylinder turbocharged diesel engines — the high-torque power core for 28-33 ton class excavators and large construction machinery.
Manufactured to Doosan/Daewoo's strict OEM standards and certified by ISO9001/TS16949, it integrates all critical components required for full engine overhaul, including premium composite graphite gaskets (meets JB/T 7762-2018 standards), high-strength alloy pistons, semi-finished dry-type cylinder liners, and precision bearings.
Designed to match the D2366 engine's 11.05L displacement (123*155mm bore-stroke), 177kW (240hp) power output, and 824 N·m torque at 1400rpm, this kit excels in harsh operating conditions (temperatures up to 250℃, pressure up to 10MPa) common in mining, quarrying, and large-scale earthmoving.
