Line Honing Information

Why It Matters

When the main bearing bores are no longer properly aligned, additional wear can occur over time. Line honing restores these surfaces so the engine block is ready for continued use.

What Is Line Honing?

Line honing is a machining service that restores the main bearing bores inside an engine block. It’s commonly performed when wear or previous machining has affected their condition.

What Are Main Bearings?

Main bearings support the crankshaft as it rotates inside the engine. Because they rely on a properly prepared engine block, the condition of the main bearing bores is an important part of engine machining.
