About Cylinder Liner/ Engine Block/ Crack Repair of MAN Main Engine/ Metal Lock and Metal Stitching

Repair undertaken by RA Power Solutions

In the case of cylinder liners, the crack was repaired from the inside and from the outer diameter as well by a metal lock process. We used special alloy locks and keys to repair the crack. The two cracks in the engine block liner sitting area were repaired by a metal lock. After repairs, the proper grinding and polishing was done on the crack area to maintain the specified tolerance.

The liners were assembled in the presence of our technicians and the engine was put on operation after the leak test. The performance of the engine after crack repair of cylinder liners and engine block is observed satisfactory.
