His son not knowing this hopped on the tractor tried to start it so he could move it out of the way, oops. Well you can see the results. I plan on either welding it back together or making a plate to bolt over the hole, any pro's or cons for either idea. Rod. [Reply]   [No Email]

Call lock-n-stitch ,tell them how thick the casting is ,they will sell you the plugs for that thickness, and also the tools needed to lace it with their plugs . Grind it to a square edge and fit another piece of cast in the hole ( fit it tight ), I use pieces of bath tub as they are very good cast iron. When finished hit it with needle scaler and you will not be able to see the repair. It is best not to use the tapered plugs for that job as you can overtighten them and bow the block . Send me an email with a phone # and I'll call you. george [Reply]  [No Email]

I looked it up online and it looks very interesting. It should work good. I'll have to find out what it costs. [Reply]  [No Email]

He did a piece for me. Looks & held great. He said the mig doesn't develop the heat that the stick will. Any thoughts? [Reply]  [No Email]

The area surounding the weld is cool and it will suck the heat from the weld area, that rapid cooling makes the heated area extremely hard and brittle. george [Reply]  [No Email]

Far as I can tell the only difference is it's very hard to weld it with nickel unless you lay it down. Brazing or doing the bolted patch can easily be done without removing the block.

I would be more concerned about the rod, if it's bent or if the brg bore is knocked out of round. [Reply]  [No Email]

My tractor (411) was at my sons with the oil pan held on with two bolts and no oil while I got the new gaskets. I put a big sign on the steering wheel. DO NOT OPERATE THIS TRACTOR. I was very concerned that something such as this would happen. Wishing you the best success. Let us know how you fix it and how well it turns out. gobble [Reply]  [No Email]

I have made many cast repairs in the past and it makes good sense. [Reply]  [No Email]
