6736-29-2110 Cylinder Liner for Komatsu 4D102 6D102 Engine

6736-29-2110 Cylinder Liner for Komatsu 4D102 / 6D102 Engine

The high-performance 6736-29-2110 cylinder liner serves as a premium precision-ground salvage sleeve engineered specifically for the robust Komatsu 102mm engine block family. Optimized to handle severe thermal cycling in heavy-duty mid-sized excavators, this dry-type liner maintains absolute structural equilibrium within the engine block core.

Technical Specifications & Structural Dimensions

Thermal Distortion Challenges in High-Boost Applications

Mid-sized earthmovers like the Komatsu PC200-6 excavator subject turbo-intercooled S6D102E engines to relentless combustion spikes and radical heat loads. Under heavy breakout force, poor cylinder cooling can induce microscopic wall distortion. If your block exhibits parent bore wear, installing the high-grade 6736-29-2110 sleeve completely eliminates localized hot spots, securing standard circular integrity and saving the engine block from scrap.

Cross-Brand Lineage & Interference-Fit Overhaul Best Practices

The Komatsu 102 series shares a direct mechanical heritage with the industry-standard Cummins B-Series engine block architecture. Because of this high-pressure cross-brand relationship, dimensional tolerances during interference-fit installation are critical. Technicians must check the engine block block bore condition for taper or rounding before pressing the new 6736-29-2110 salvage sleeve. Liquid nitrogen or specialized cooling induction is strongly suggested to slide the sleeve into place effortlessly without scuffing the critical outer mating surface.

FAQ

Does the 6736-29-2110 fit both 4-cylinder and 6-cylinder Komatsu 102 engines?

Yes. This specific cylinder sleeve is standard across both the 4-cylinder (4D102 / S4D102) and 6-cylinder (6D102 / S6D102) powerplants, as they share identical 102mm cylinder block bore architecture and piston stroke constraints.

Is this thin-wall sleeve a finished or semi-finished component?

The 6736-29-2110 is generally supplied as a semi-finished liner. Because dry salvage sleeves encounter massive squeeze pressure during the block insertion process, the inner bore must be honed to exact standard cross-hatch specifications post-installation to achieve a perfect piston ring seal.
