huge hole in crankcase

[770]

I have gotten a huge hole in the right side crankcase and I wondered if it is worth the money or possible to fix this hole.

That is...

If you wanted that fixed it would need welding then the entire thing cut flat perfectly. It would be a better option to get another crank case unless it's cheaper to have it welded then machined. Is it a 2 stroke or a 4 stroke engine?

Take it to a weldor and ask them to weld it. How did it get broken?

It could be welded. I wouldn't bother.

How did you manage that then?

What's it off and how much do you give a shit?

I'm looking at that and thinking you could probably lumiweld it back in place then glue an aluminium patch over the outside with JB weld for good luck. Do up that bolt last.

Another (really, really bad) part of me thinks that if you were to put the bolt back in so that piece was held onto the cover with an appropriately thick piece of paper gasket, coated the broken edge in instant gasket then bolted the cover back in place, it'd probably be oiltight.

It's not like its pressurised, it just needs to be oiltight.

Both are bodges. The latter an utterly horrific one (although I know people who'd try it, might have myself once upon a time). Both have the potential to dump your engine oil out at any time.

Just find the elves that were working on the pit and dirt bikes at the BCF BBQ. I swear, they made a piston out of grass at one point...

Fixable with a top quality aluminum adhesive / epoxy or as said aluminum weld. Both are probably cheaper and less hassle than splitting and replacing crankcases

[gavbriggs]

I would clean the break with acetone or similar to remove any oil residue. Then chuck some sort of oil resistant glue/liquid teal etc in the joint, bolt in opposite casting and join it all up. One set remove case and bolt, tidy it up. Apply more gloppy shit and put it all back together and ebay, you can get the outside looking standard as the inside will be sealed and no one will ever know there's a join!

is it wrong that I hear the derp song https://www.youtube.com/watch?v=ooNbVgSSguI in my head while picturing him hitting it with a hammer. "Smack, Smack, Smack" scratches head, "this is on tight" "smack smack smack, Yay its off!" "awwww"

I'd try a durafix welding rod and blowtorch, have successfully welded a hole in my VTR1000 clutch cover when I dropped the bike damaging it.

I'm sure some normal home superglue would do the trick on that.

[Ed Case]

JB Weld is the stuff, it'll work a treat.
