6128-21-2216 Cylinder Liner for Komatsu

6128-21-2216 is a dry cylinder liner for the S6D155 engine used in Komatsu equipment. It is a new aftermarket spare part manufactured by CTP (Costex Tractor Parts).

The component is intended for installation in the engine cylinder block as the replaceable cylindrical surface in which the piston operates. The listed application identifies the Komatsu S6D155 engine as the compatible engine model. The part is described as a dry liner sleeve, meaning that the liner is supplied as a separate sleeve for installation in the cylinder block rather than as a complete engine assembly.

Fitment

• Equipment manufacturer: Komatsu
• Engine model: S6D155
• Application: Komatsu equipment powered by the S6D155 engine

The available application data specifies the S6D155 engine but does not provide a machine model or series list. Fitment should therefore be confirmed by matching the engine model and the required part number before installation.
