description

Cylinder liner is the inner wall of combustion chamber. Wet liner outer surface contacts coolant directly, inner bore is sliding surface for piston rings. Bore scoring, excessive wear, cavitation perforation and aged O-ring leakage cause oil burning, blow-by gas, coolant mixing with engine oil, overheating and power loss, even piston seizure and water ingress into block.

Part No.: 1878159960
Part Name: cylinder liner assembly
Matching Engine: Isuzu 6WG1
Installation Position: Cylinder liner seat of engine block
Matching Parts: piston, piston ring, O-ring, overhaul gasket kit selected as overhaul set on demand

Application Scenarios

Fit for Isuzu 6WG1 series engines, compatible with Hitachi ZX450, ZX470, ZX670 large excavators and Isuzu heavy-duty engineering trucks. Suitable for heavy mining and large earthmoving conditions. Used to replace old liners with cavitation, scoring and excessive wear during engine overhaul.

FAQ 

Q: Can I replace only one cavitated leaking liner?
A: Not recommended. Other liners share same service time with hidden cavitation risk, single replacement causes recurring leakage and piston seizure.

Q: What will happen if liner protrusion height is incorrect?
A: Insufficient protrusion leads to low clamping force and blown head gasket; excessive protrusion deforms cylinder head and causes crack or gasket failure.

Q: Can old O-rings be reused if they still look elastic?
A: O-rings degrade under thermal cycling with invisible microcracks. Reuse often causes delayed water leakage, replace all O-rings.

Q: Can lightly scratched liner bore be reused after polishing?
A: Polishing damages honing pattern if scratch depth exceeds limit, oil film cannot form properly and piston rings wear rapidly, new liner replacement is required.
