Product Description
The 65.02543-1458 Liner Kit is the core overhaul component for Doosan DB58-5 engine installed on DH220-5 excavators. This complete kit includes cylinder liners, aluminum pistons, piston ring sets, piston pins and snap rings, matched with precise clearance for one-stop engine rebuild. The cylinder liner adopts high-hardness cast iron with anti-wear treatment, resisting abrasion from dust and high temperature under construction site heavy loads. Pistons and piston rings are precision machined to seal combustion chamber tightly, effectively reducing engine oil consumption and blow-by gas. All parts are 100% tested for size tolerance, hardness and air tightness, realizing direct installation without extra matching work.

FAQ
Q:What is the function of a cylinder liner kit?
A: It forms the main friction assembly of the engine. The liner provides smooth moving track for pistons; pistons convert combustion energy into power; piston rings seal gas and scrape redundant oil off cylinder walls; piston pins connect pistons and connecting rods. It ensures sufficient power, low oil burn and stable heat dissipation for excavator engines.
Q: What are the fault symptoms of worn liner kit?
A: Excessive blue smoke during startup, serious engine oil consumption, weak excavator power, loud engine knocking noise, large blow-by gas, and cylinder scoring in severe cases.
Q: OEM or aftermarket?
A: Premium aftermarket liner kit fully compliant with OEM original technical standards.
Q: Delivery time?
A: Stock goods ship within 3–5 days; bulk mass orders take 7–15 days based on order quantity.
Q: Packaging options?
A: Neutral export cartons, OEM branded boxes and customized printed packaging are all available.
