Cracked Boat Engine Block Repair

If your boat engine block is cracked and in need of repair, make sure you make the right repair. This means getting to the heart of the problem and never trying to weld it. If you're the owner of a Cummins 5.9-liter engine with a number 53 cast on the side, you may have found a crack--even after regular operation. LOCK-N-STITCH Inc. products offer you a definitive solution.

What the LNS technicians have found with this particular crack issue is that it has no bearing on the quality of the casting or on your load placed on it. Rather, it's a confluence of physical characteristics, plus the pressure of thermal expansion that can cause the crack. Incomplete warm-up after a cold start is the biggest problem.

LOCK-N-STITCH Inc. offers cast iron fusion oven welding at extreme temperatures, in general, for welding of cast iron. But for an assembled engine, that is not possible. For repairs to assembled components such as this Cummins 5.9 engine block, LNS has developed a distinct solution that consists of metal stitching to fix and seal the crack and a reinforcing bracket that spans the repair site to provide optimum support and strength. This is the absolute best way to avoid additional cracks and get the full life out of your boat's engine.

The technicians of LOCK-N-STITCH Inc. can come to your site to perform the repair, or they can simply send you the repair kits with detailed instructions. The choice is yours. To find out more, call 800-736-8261 or 209-632-2345. Or email LNS directly at gary@locknstitch.com.
