Cast Iron Repair

Cast iron repair is never a job for a simple weld. Before you get out the welder or have your local welding shop attempt it, understand that most often welding actually ruins the cast iron around the weld by making it brittle and hard with additional cracks and leaks. A permanent fix will require metal stitching, but don't expect to be able to drill and tap the damaged cast iron after a failed welding attempt.

LOCK-N-STITCH Inc. has over 30 years' experience in dealing with the toughest and most mysterious cracks in cast iron. Among these difficult issues is the cracks endemic to the Cummins 5.9-liter "53" block engines built between 1999 and 2001. The "53" is cast on the lower front of the block on the drivers side.

Many truck, bus, motor home, and tractor owners have discovered cracks in their engine blocks, even with regular operational use. And although the 53 block crack issue is not present in every one of these engines, where it does exist, the problem has been difficult to solve. Now LOCK-N-STITCH offers the most comprehensive and long-lasting solution, based on the compilation of several years of experience and interviews with drivers.

The technicians of LOCK-N-STITCH can perform this repair for you, no matter where you are in the world, or they can provide you with training in the Cummins 53 block repair process and send you the repair kits, which include easy-to-understand instructions.
