For Komatsu 6D170 S6D170 Engine Parts 6162-23-2210 Cylinder Liner

6162-23-2210 Cylinder Liner Sleeve for Komatsu 6D140 / S6D140 Engine

The high capacity industrial matching 6162-23-2210 cylinder liner is a precision engineered wet-type sleeve designed to rebuild combustion efficiency inside Komatsu 140mm big bore diesel platforms. Cast from centrifugally hardened molybdenum iron compounds, this heavy equipment core component ensures absolute wall stability and minimal ring wear under continuous earthmoving duty cycles.

Technical Specifications & Structural Dimensions

Bulldozer Back-Shock Deflections and Upper Flange Counterbore Crushing Mechanics

Heavy mining crawlers like the Komatsu D155A-3 bulldozer or D155A-5 bulldozer run through intensive rocky ripping tasks that generate massive structural shockwaves traveling back into the chassis block frame. In these high-impact configurations, the 15.2-liter Komatsu S6D140 engine crankcase block encounters intense variable twisting stress. This kinetic force can warp the main deck receiver joints, leading to localized uneven crushing of the upper counterbore seat area. Deploying our premium metallurgical grade 6162-23-2210 wet sleeve provides advanced flange load distribution, protecting the combustion fire ring line from tracking gas leaks.

Electrochemical Galvanic Pitting Defense Under Extended Fluid Thermal Cycling

Heavy production machines running extended operating shifts frequently encounter water system additive breakdown. When glycol components degrade over prolonged service intervals, the resulting fluid acidity breaks down the factory passivation film along the lower block seating lands. This specific environment triggers electrochemical galvanic pitting across the lower packing guides of the 6162-23-2210 liner, eventually letting coolant leak directly into the engine block base pan. Our replacement sleeves utilize specialized refined raw alloys to counter galvanic pitting attacks, maintaining tight sealing contact lines across long industrial seasons.

FAQ

Does the 6162-23-2210 fit both the early PC450-6 and late PC450-7 excavators?

Yes, this heavy-duty wet sleeve is fully compatible across all generation blocks within the Komatsu 140 series block framework, because the primary block internal bore and seating step constraints remain standardized. Please provide your exact emission specification prefix to verify localized tracking details before fulfillment.

What inspection tasks are required to guarantee a leak-proof lock with this wet liner?

Due to the extensive cooling water channels wrapped around the 140mm sleeve, total elimination of rust and scale deposits from the upper and lower block receiver seating grooves is a critical task. Rebuilders should verify the correct liner protrusion height using a dial indicator across all cylinder block holes before completing final head bolt torque assembly steps.
