Honing is the process of conditioning the surface of the cylinder to ensure the piston rings are well lubricated during operation. Honing creates small cross hatched imperfections in the cylinder bore. These small imperfections ensure oil is retained in the wall of the cylinder. Without correct honing, your pistons could wear out very quickly due to the friction during operation. Walkers ensure the honing of your cylinders is done correctly and with precision keeping you running for a long time.

A cylinder liner is a cylindrical part that fits into the engine block to form the cylinder. The liner not only prevents the combustion gasses from escaping, it transfers the heat generated by the piston to the coolant in the engine block. The liner is a vital piece of kit for the engine block, so ensuring correct fitting is essential. At Walkers of Rochdale, this work is carried out with absolute precision.
