Boring and Honing
Even if a cylinder is too damaged to be bored we can still reclaim it by ‘sleeving’ with a liner.
If a cylinder block has been subject to heavy wear through the main bearings damaging the main line surfaces, we can line bore and also supply oversize main bearings.
Boring takes the ‘wear’ out of a cylinder using a precision cutting tool, re-sizing the bore to take the next available piston size.
The cylinder is then finish honed to obtain the correct surface finish and finally plateau-honed to create a surface that will provide good life span and aid lubrication.
