Nice,sunny day yesterday and thought I should get a jump on yard work. Riding along noticed the right side foot rest had some little dots of moisture on it. Wasn't drizzling, then I noticed oil spewing from the crankcase.
3" crack.( I can't figure out how to post a picture), It starts at the top of the case. New engine, plus bit of work to install it, $1260.00. New 46" mower, $2350.00. Can I weld it? maybe, but not sure it will last long.( I am a competent welder, have a tig and mig welders). Mower is a Cub Cadet LT 1040, 15yrs old and this engine has been a lot of trouble.
Any thoughts?
Sorry but to me JB Weld is hell of a con job. Nothing I have tried to has held. Either find a welding shop that an experienced aluminum welder or just replace the short block.
Besides it takes nearly 3000 F just to break the aluminum oxidation layer and the aluminum itself will melt quickly at 800-1500F. And that oxidation layer is pretty thick too.
After taking it apart and looking inside, I can see the crack split in several directions. It looks like a bit more cracking and a piece will fall out. Don't think it is worth trying to fix.
Engines for Less has a replacement for $1200. Any recommendations on engine suppliers?
Thanks,
Will

I count six threads on this LT1040. What's up with that?
