This Cum mins M11-0 Excavator Engine Overhaul Kit (Core OE No. 4025297 / 4090008) is a professional heavy-duty rebuild solution engineered exclusively for Cum mins M11-0, M11, ISM11, QSM11 inline 6-cylinder turbocharged diesel engines — the high-torque power core for 36-50 ton class excavators and large construction machinery.
Manufactured to Cum mins' strict OEM standards and certified by ISO9001/IATF16949, it integrates all critical components required for full engine overhaul, featuring premium multi-layer steel (MLS) head gaskets and high-temperature composite gaskets optimized for extreme sealing performance, paired with forged steel crown articulated pistons, mid-stop design cylinder liners, and precision-ground bearings.
Designed to match the M11-0 engine's 10.8L displacement (125*147mm bore-stroke), 220-350 HP (164-261kW) power output, and 1376-1600 N·m torque range, this kit excels in harsh operating conditions (temperatures up to 650℃, pressure up to 18MPa) common in mining, quarrying, and large-scale earthmoving.
