Ouch!

I removed my cylinders over the weekend, it was not pretty. By the time I realized that they were stuck on a stud, the pistons were out of the sleeves, so I ground off the offending stud. That is not the OUCH. I somehow managed to ding the case.



Is there enough good surface there to make a seal? can I fill the dent with something like JB Weld, or will this have to be welded and machined?

The seal is the O ring, so the oil shouldn't leak from there, and it's on the side away from the cylinder bore. I bet it will be fine, although filling the nick can't hurt. Sure welding and refinishing would be the correct fix, but I bet it's OK.

I've used what used to be called Marine-Tex to repair stuff like that, no problem. I'm sure JBWeld for aluminum will be fine.

+1 to this...

I've seen a guy patch a hole in his outboard motor cylinder wall when his engine threw a rod with Marine Tex, he said the motor had over 450 hours on it since it did that. That's got to be good stuff.

OK, I can breathe again!

Thank you all for putting my mind at ease. I will get some Marine Tex, fill the nick and move on. My next step is to evaluate the cylinders and pistons.

thanks again!

There is even enough surface left for the paper gasket to seal against. That, plus the o-ring will do the job. If you want to fix it for appearances, it's probably a good idea, but I don't think necessary.
