6128-29-2210 Cylinder Liner for Komatsu 6D170 / S6D170 Engine

6128-29-2210 Cylinder Liner Sleeve for Komatsu 6D170 / S6D170 Engine

The massive displacement 6128-29-2210 cylinder liner is a specialized industrial matching component engineered to handle extreme kinetic force distributions inside Komatsu 170mm big bore diesel engines. Cast from heavily refined alloyed cast iron matrices, this foundational engine core component ensures maximum operational durability and low coefficient friction tracking under severe rock excavation operations.

Technical Specifications & Structural Dimensions

Abrasive Ore Dust Mitigation and Piston Crown Thermal Radiation Protection

Ultra large earthmovers like the Komatsu PC800 excavator or D375A bulldozer operate in dense blasting zones filled with abrasive quartz and iron ore dust particles. If fine particulate bypasses secondary air filtration lines, it settles inside the upper combustion ring belt, triggering aggressive scraping wear along the top sleeve ridge. Our premium metallurgical alloyed 6128-29-2210 liner core features localized wear resistive compound distributions. This metallurgy successfully counteracts dust scraping abrasions while managing the extreme thermal radiation generated by high displacement pistons during full throttle operations.

Engine Block Deck Creep and Structural Counterbore Twisting Controls

The high displacement 23-liter Komatsu S6D170 engine platform exerts colossal rotational torque output exceeding 2000 Nm. Under deep pit quarry loading, these constant mechanical loading patterns induce micro-scale structural block deck creep and twisting across the cylinder block housing frame. If the replacement sleeve lack adequate flange shoulder ductility, these localized twisting moments can cause unexpected structural failure near the upper retention landing area. Utilizing our standard ground 6128-29-2210 component provides optimized uniform stress distribution across the parent block receivers, preserving a absolute fire ring lock line even under intense machine torsional deflection.

FAQ

Does the 6128-29-2210 fit both early PC750-6 and late PC800-8 mining excavators?

Yes, this heavy duty liner fits across multiple machinery models utilizing the Komatsu 170 series block framework, since the base cylinder block parent bore and sleeve landing parameters remain standard. Always double check your specific emission tier codes prior to finalizing logistics lines.

What unique steps are required to seal the 6128-29-2210 wet block liner assembly?

Because the huge 170mm block contains expansive water channels, ensuring meticulous debris extraction from the lower block receiver pack grooves is a mandatory task. Technicians must apply a thin layer of specialized hydraulic soap lubricant to the rubber packing seals before vertical deployment to prevent ring rolling or cutting during sleeve seating.
