Main Bearing tunnel in worn engines often exceeds factory specifications and to rectify this we re-machine to factory quality tolerances. With a capacity of 2500mm long and be able to a diameter of 680mm, the L2500 V can also re-machine worn thrust faces and re-machine camshaft tunnels.

Sunnen Line Honing is extremely accurate, allowing us to re-size main bearing bores to tolerances that exceed original factory (OE) specifications for concentricity and alignment.
