Cracked Case!

[305explr]

I know how the case goes together and how the bearings and pins have to fit, so can scarcely believe I did this...but apparently I did. Sigh. I'm sick over the situation.

Certainly I'm not the 1st _______ (insert label there) to do this. Can this be welded?

Advice appreciated--as always.

May be better to get another half.

May be able to weld it but you may warp the bearing and seal bore in the process.

I'm with Joe, get another case.

Sorry,

Gary

Folks do this all the time. Peal the raised area away and wash it and the area with spray contact cleaner. Mix a small batch of J.B. WELD and put it in the area followed with the chip then put a batch on the entire area and let it set. Make sure the whole area is covered when hard and you have it repaired enough to use the engine. If you don't want to do this then split the case and remove the chip and drive the knock pin out and wash with cleaner and J.B. the chip in place and before hard punch pin in until it moves the chip then push the chip down and add more J.B. ...............lm

LM,

I used JB Weld on a spider crack in the head of a Matchless. Rode the bike for two years that way and it was still holding up when I sold her. JB Weld is good stuff, with Marine Tech running a close second. I would certainly give it a try before I went through the time and expense of locating another case.

Thanks for the advice, everyone. I walked away from the project for a short while, and am now preparing to do the repair. I'll keep you posted.
