Fix Cracked Engine Block

When you're ready to fix your cracked engine block, turn to the experts of LOCK-N-STITCH Inc. to give you a real advantage. For over 30 years, they have brought the best solutions to market with products and full repair kits that fix cast-metal cracks permanently. For those with a Cummins 5.9-liter engine with a number 53 cast on the block, LNS has just the cure.

This crack repair in the cast iron of the Cummins block should absolutely not be attempted by electric welding. It's important to know how the metal you want to weld will respond to arc welding--in this case, cast iron. This metal cannot absorb the contractive stress and hardening caused by the rapid heating and cooling of an electric weld. Cast iron sets the rules, not a welding rod manufacturer.

LOCK-N-STITCH Inc. developed and patented the best way to solve the problem with their C Series metal stitching pins coupled with their LC59RB reinforcing bracket.

Metal stitching seals the crack while adding strength and avoiding all of the problems that prevent welding from working. Professional casting repair companies never arc weld on cast iron because it causes more problems than it solves. The stitching pins are screwed into the crack, slightly overlapping into each other, to seal the crack mechanically. The new bracket spans the repair to provide additional reinforcement for the long haul.

LOCK-N-STITCH Inc.'s technicians and products are used by all the heavy hitters, including Cummins Diesel, Mack Trucks, Caterpillar, and Chrysler.
