Our reconditioning centre in the Netherlands has just completed the repair of yet another externally damaged cylinder liner. We carry out this kind of repair quite frequently.

External damage to a cylinder liner is usually caused by rough handling. Liners are made of cast iron and cast iron is brittle. If a liner is dropped on the floor or is otherwise handled roughly, then material may chip off. Most damages occur in the vicinity of the o-ring grooves, where the material is thin.

If such a liner has to be scraped, then it is obviously a big waste. This is why we frequently repair them. Typically, the repair costs amount to approximately 20% of the replacement costs.

The following pictures show three examples of such repairs on liners of different sizes: An 84-bore liner, a 72-bore one and a 60-bore one.
