Maximum Durability: Komatsu 6D140 Cylinder Liner for Industrial Diesel Engine Parts

Featuring boron-alloyed cast iron construction, this Komatsu 6D140 Cylinder Liner (OEM: 6211-21-2210) delivers superior SA6D140 Sleeve durability for high-horsepower mining applications. As a vital component in our Industrial Diesel Engine Parts wholesale catalog, it provides a direct-fit solution for restoring cylinder compression in heavy-duty Komatsu power units.

Designed to withstand the extreme thermal cycling of 140mm bore engines, this liner addresses critical stability issues in high-hour blocks. It is engineered specifically for equipment like the PC600 and PC750-6, where structural integrity is paramount to prevent coolant contamination and maintain job-site productivity.

Engineering Specifications for Cylinder Liner Casting

Technician’s Note: Installation & Inspection

Technician’s Note: Always measure the liner protrusion (stand-out) above the block deck before final assembly. Incorrect protrusion is the primary cause of head gasket failure and flange erosion due to vibration in the SA6D140 series.
