RECONDITIONING
Reconditioning a worn engine component is frequently more economical than buying a new one, average cost being only 40-60 per cent.
Parts such as exhaust valve housing and piston crowns are available on an exchange basis. The return of a defective, but repairable item is promised and the operator must immediately supply the vessel with a reconditioned component. Among the components, which are likely to be continually reconditioned, are piston crowns, cylinder covers, main bearings, crosshead bearings and injection elements.
Damaged exhaust valve seats of an engine are cut off from the valve housing and are replaced by new hard-surfaced seat rings. Piston crowns with worn ring grooves must be cleaned, subjected to crack detection and machined to the original drawings.
If the damage requires, the complete crown will be machined to the original drawings, so that, after reconditioning, parts of the piston are restored to the original quality. The cost of such repair amounts to only 50 per cent of the price of a new component and the life-time is nearly the same.
