description

The cylinder liner kit is the core wear-resistant inner lining of diesel engine cylinder. It provides precise friction surface for reciprocating movement of piston and piston rings, isolates high-temperature combustion gas and transfers heat through cooling system to ensure normal combustion. Scoring, out-of-roundness, excessive taper, inner wall wear and aged sealing o-rings will lead to oil burning, blow-by gas, low cylinder pressure, power loss and coolant leakage into cylinder, and severe cylinder scoring or seizure in serious cases.

Application Scenarios

Fit for Isuzu 4BG1 series engines, compatible with Hitachi ZX120, ZX130, ZX200 excavators. Suitable for earth excavation, sand and stone transportation and light & heavy mining working conditions. Used to replace worn, scored and leaking old cylinder liner kits during engine overhaul.

FAQ 

Q: Can slightly worn cylinder liner be reused without scoring?
A: Measure inner taper and roundness first. It can be kept if within OEM limit. Replacement is required once wear exceeds tolerance even without scoring, to prevent oil burning later.

Q: Why must the sealing o-rings be replaced together with new liners?
A: Used seals lose elasticity after compression aging. Reuse will easily cause water leakage and oil-coolant mixing failure.
