A1: Symptom: Blow-by gases in the crankcase and excessive lubricating oil consumption. Diagnosis: In mining equipment like the Komatsu D155, cavitation pitting on the outer wall (water-side) or ring-groove scuffing on the inner wall are common. Solution: Our 3055099 liners are made from boron-alloy cast iron using a centrifugal casting process, which creates a denser microstructure that resists vibration-induced cavitation and ring scuffing.
A2: Technical Detail: Protrusion height (liner height above block deck) must be verified between 0.03mm – 0.10mm. Pro-Tip: Never install liners without inspecting the block counterbore; an uneven counterbore will cause the liner to tilt under pressure, leading to instant head gasket failure.
A3: Diagnosis: The NTA855 engine generates high thermal loads that can soften standard cast iron, causing it to wear prematurely against the piston rings. Our Solution: We use boron-alloy cast iron, which provides extreme hardness and self-lubricating properties. This ensures the liner maintains its cross-hatch honing pattern for the entire duration of the engine’s service life, even under the high-dust, high-load conditions of mining operations.
