Align Boring & Align Honing

Align boring restores the alignment of your engine’s main bearing bores. Over time, heat and stress can cause distortion or misalignment, leading to excessive wear or even engine failure. Precision align boring ensures the crankshaft runs true and smooth.

Align boring corrects the alignment and size of the bearing bores, while align honing provides the final surface finish and exact clearance for smooth crankshaft rotation. They’re often done together for the best results.

Symptoms include unusual engine noise, low oil pressure, or bearing wear. However, the only sure way to know is through precise measurement during inspection — we’ll check and advise if machining is needed.

Yes — restoring perfect alignment reduces internal friction, increases efficiency, and improves overall engine balance and longevity. It’s especially important for performance and high-revving engines.

We can perform line boring and honing on most petrol and diesel engines, from everyday vehicles to high-performance race engines and commercial fleets.

Our CNC equipment allows for extremely tight tolerances — we ensure every main bore is perfectly straight, correctly sized, and finished to exact specifications.
