Following job was done pertaining to engine block repair:-

The complete engine block was subjected to crack detection by MPI test by level 3 qualified technicians.
Main journal housings of engine block were dimensionally checked for taper and ovality was recorded.
The damage to engine block was so serious that we have no option but to cut off the damaged portion of the engine block.
The new casting piece was manufactured with the similar profile of damaged block of wartsila 12V32 and was given original profile by onsite machining. The piece was assembled by metal stitching and metal locking process.
All the main journal housings were corrected by onsite machining, maintaining the main journal housing bore size strictly as per the engine manufacturer’s limits.
