Cylinder Liner Kit Set for Weichai R4105 / R6105 / R6113 / K4100 / K4105 Diesel Engines

This cylinder liner kit set is engineered for the Weichai R-series and K-series diesel engine families — covering R4105, R6105, R6113, K4100, and K4105 models. Weichai is one of the largest heavy-duty engine manufacturers in the world, and their powerplants drive a vast range of equipment including 3-16 ton forklifts, wheel loaders, excavators, generator sets, marine propulsion systems, and heavy trucks. Cylinder liners in these engines must withstand extreme combustion pressures and temperatures while maintaining precise bore geometry for thousands of operating hours. When liners wear — indicated by excessive blow-by, high oil consumption, low compression, and hard starting — a quality liner kit replacement with fresh piston rings restores compression, oil control, and power output to original specifications without the cost of a complete engine replacement.

Each liner is manufactured from centrifugally cast alloy iron with a refined pearlitic matrix for exceptional hardness, wear resistance, and dimensional stability under thermal cycling. The inner bore receives a precision plateau-honing treatment that creates a controlled cross-hatch surface — retaining oil in the valleys for ring lubrication while providing flat load-bearing plateaus for rapid ring seating. Wet-type liners (R4105, R6105, R6113) feature precision-machined O-ring grooves at the lower register to ensure a leak-tight coolant seal, while dry-type or wet-type configurations are available depending on the specific engine model. Each liner is matched with a complete piston ring set: a barrel-faced or chrome-plated top compression ring, a taper-faced second ring, and a spring-expanded multi-piece oil control ring for consistent oil film control throughout the service life.

Compatible with Weichai-powered equipment across multiple industries — forklifts (3-16 ton diesel models from Heli, Hangcha, Lonking, Tailift), construction machinery (SDLG, XCMG, LiuGong wheel loaders and excavators), generator sets, marine engines, and Weichai-powered trucks. Please specify your required engine model (R4105, R6105, R6113, K4100, K4105) when ordering so we can confirm the correct liner type, bore diameter, and ring specifications.
