With expertise and reliability, TMH Drechsler offers customized repairs for your cylinder covers. Our qualified specialists with many years of experience deliver efficient and precise optimal results. Customer collaboration is highly individualized and extremely flexible.

Your cylinder covers are inspected, measured, and, if necessary, pre-machined, joint-filled, welded, and stress-relieved by annealing. The areas around the injector bores are hardfaced. All contours are then re-machined back to their original dimensions.

Systematic quality inspections and reliable diligence accompany every stage of the process as a matter of course, right through to on-time delivery.

The acceptance of the refurbished spare parts is carried out in accordance with the guidelines and regulations of DNV GL.
