Cum mins 6CT Engine Gasket Kit OE 4025271 for Hyundai R300LC-5/R305 Excavator for Cum mins Engine Parts
This Cum mins 6CT Excavator Engine Gasket Kit (Core OE No. 3938267 / 3800750 / 4025271) is a professional heavy-duty sealing solution engineered exclusively for Cum mins 6CT, 6CTA, 6CTAA inline 6-cylinder turbocharged diesel engines — the reliable power core for 25-35 ton class excavators and mid-to-large construction machinery.
Manufactured to Cum mins' strict OEM standards and certified by ISO9001/IATF16949, this full gasket kit integrates all critical sealing components required for engine maintenance and repair, featuring premium multi-layer steel (MLS) head gaskets and high-temperature composite gaskets (steel + graphite, non-asbestos) optimized for extreme sealing performance in harsh working environments.
Designed to match the 6CT engine's 8.3L displacement (114*135mm bore-stroke), 185–325 HP (138–242kW) power output, and 680–1220 N·m torque range, this gasket kit excels in extreme operating conditions (temperatures up to 600℃, pressure up to 16MPa) common in earthmoving, quarrying, and medium-scale mining.
