Cylinder Resleeving, Boring, Honing & Porting

Serco is able to bore, hone, or resleeve any cylinder. When boring or resleeving a cylinder the cylinder needs to be completely torn down. The typical time to resleeve a cylinder is between 2 - 3 hours. Please note: It is sometimes necessary for the cylinder to be welded. Welding the cylinder is an additional charge.

Wet Blasting

The Wet Blast process is a unique blast finishing technique that can be used on motorcycle, automotive and marine parts and is best suited for ferrous and non-ferrous metals. The wet blast process utilises abrasive media, water and compressed air to induce a scrubbing action on the surface of the material being processed. Wet Blasting does not cause surface damage to components, therefore threads, seal surfaces and other sensitive areas do not have to be protected before wet blasting.
