Cylinder liner assembly 5878137440 for the 4HE1-T engine in NPR71 models

Product Design Philosophy

Dry-type liner design for 4HE1-T engines. Centrifugal casting ensures uniform material density. Precision machining provides exact fit with 110mm bore, guaranteeing reliable combustion sealing and durability.

How it works

Press-fitted into the cylinder block bore, the liner forms the combustion chamber wall. It seals with piston rings, guides piston movement, and transfers combustion heat through the block to coolant.

Problems the product can solve

Fixes power loss, oil burning, and bore scoring caused by worn or scored liners. Restores cylinder sealing, extends engine life, and eliminates the need for complete block replacement.
