Mitsubishi Cylinder Liner for Fuso Heavy Truck 8DC10 | OEM ME062536

Technical Q&A: Mitsubishi 8DC10 Cylinder Liner

Why do 8DC10 cylinder liners suffer from pitting on the outside wall?

Pitting on the exterior of the liner is caused by “cavitation erosion.” In massive V8 engines like the 8DC10, the violent combustion process creates high-frequency vibrations in the cylinder wall. These vibrations cause microscopic coolant bubbles to rapidly form and collapse against the metal, literally blasting tiny pieces of iron away over time. Our ME062536 liners are cast with a specialized boron-alloyed iron that significantly increases the material’s density and tensile strength, effectively resisting this destructive cavitation process and preventing coolant from leaking into the crankcase.

Why is the cross-hatch honing pattern critical for the ME062536 liner?

The inner bore of the cylinder liner cannot be perfectly smooth; it requires a specific micro-finish known as a cross-hatch pattern. This precise plateau honing acts as a microscopic reservoir, retaining a thin film of engine oil on the cylinder wall. This oil film is absolutely critical for lubricating the piston rings as they travel up and down at high speeds. Without the correct cross-hatch angle and depth, the rings will either experience dry friction (causing severe bore scuffing) or fail to seat properly, resulting in immediate compression loss and heavy oil consumption in your Fuso truck.

Do you supply the associated piston rings and liner O-rings?

Yes, we do. When replacing wet cylinder liners like the ME062536, it is mandatory to install brand-new, high-quality rubber O-rings to seal the coolant jacket and prevent oil-coolant mixing. We supply complete 8DC10 engine rebuild kits, which include the cylinder liners, matched piston assemblies, piston rings, and all necessary sealing gaskets for a professional overhaul.

Is this cylinder liner suitable for marine 8DC10 applications?

Absolutely. Marine environments place continuous, high-load stress on the 8DC10 engine. Our boron-alloyed cylinder liners are engineered to withstand the sustained thermal loads of marine propulsion and auxiliary generator use. The exterior is treated with a specialized anti-corrosion phosphated coating to resist rust during transit and provide extra protection within the engine’s water jacket.
