cracked trans case

[724wd]

looks like the dowel was stuck when they tried to pull this trans.  Anyone ever seen this kind of damage repaired or run a trans in this condition?  It was dark when I bought it and it's long past due to do anything about it.  It's a K-case 350 and that's the only reason I'm at all interested in options to fix or run.

I cracked a TH350 case one time like that. Took it to a shop and I'm pretty sure they tig welded it. It worked fine and it got the holy crap beat out of it.

Skilled welders repair cylinder heads all the time with different welding techniques. Should not be a problem.

Just pulled a similar case out. We had a spare laying around so dumped the guts in that but most radiator shops have a tig guy that can weld it up for you or a marine repair place.   Or farm fix - drill a hole at the end of the crack, layer on a bunch of jb weld on both sides and your golden.

I have a BW super t10 that has a welded area about the size of that right around a bolt boss in the bell housing. I've hit that trans with 550 to 650 n20 assisted hp in a 3000lb car with slicks on a vht covered track, no problems so far. Clean up the mating surfaces well, that's what takes the brunt of the force anyway. Unless your running some goofy trans mount I doubt you'll have any issues. Will it have a married t case hanging off of it?

If the bolts still line up and the crack doesn't run into a mated surface you can weld it. If the bell housing is a bolt on I'd replace it. Driving on it ling term you run the risk of the crack going from minor fix to catastrophic failure.

stop drill the crack and make sure all the bolts are tight . my guess is you wont have any issues . if your gonna rebuild it have it welded .

Looks to be aluminum? If so clean real well, lightly gouge out the crack , drill the end a bit and make sure who ever welds it uses 4043 tig Rod as it is a casting
Good luck

This.  First thing that came into my mind when I looked at the photograph of the crack.

It'll be backed with a Dana 18, and live behind a 4 cyl 153 Chevy.

Kinda what I was thinking... and hoping!     It will be rebuilt, so I'll look for a local guy that can weld'er up.     Thanks everyone!

so when you guys are talking about drilling a hole to stop the crack... are we talking 1/8th inch?  1/4? 

[JDHasty]

Any welding shop can repair it for ~$30 -$50.  The local vocational school will probably do it for $15

Don't use it as is, the crack absolutely will propagate

The problem is where does the crack terminate?  You don't know is the answer.   Just take to a welding shop and have it welded.  It is a simple job.
