This Komatsu 6D125-5 gasket kit (OE No. 6148-K1-9900) is a professional heavy-duty sealing solution engineered exclusively for Komatsu 6D125-5 / SA6D125-5 turbocharged aftercooled diesel engines — the robust 11.04L 6-cylinder power core for mid-to-large construction, mining, and material handling equipment. Meeting Komatsu's strict OEM standards, it fits iconic machinery including Komatsu PC450-5/PC490-5 excavators, WA470-5 wheel loaders, and HD325-5 dump trucks, delivering 191kW (256hp) for heavy workloads. Featuring premium multi-layer steel (MLS) gaskets and reinforced metal-core seals, every part is precision-machined for leak-proof fitment, durability under 600℃ high temperatures and high pressure, and restored engine performance. Passing ISO9001/TS1649 quality tests, this kit is ideal for engine overhaul, full rebuild, or critical sealing maintenance in construction, mining, and industrial applications.
