Cylinder liner assembly 1878129861 for the 4HK1 6HK1 engine in 700P models

Product Design Philosophy

Heavy-duty dry liner set for 4HK1/6HK1 engines. Precision-cast wear-resistant iron alloy with 115mm bore and grade-matched sizing (1X/3X), ensuring reliable sealing and thermal stability under high turbocharged pressures.

How it works

Dry liner press-fits into cylinder block bore, forming combustion chamber wall. Seals with piston rings, guides piston movement, and transfers combustion heat through block to coolant for thermal management.

Problems the product can solve

Fixes bore scoring, power loss, and oil consumption from worn liners in 4HK1/6HK1 engines. Restores cylinder sealing and extends engine life without replacing the entire cylinder block.
