Anyone have an idea if this is repairable by a skilled welder, or am I buying a new crankcase?

It's the front engine mount on the right side.

Ugh, it's embarrassing. I was trying to install a frame slider/bobbin and it didn't go as smoothly as this:

It could be fixed.

Would require a complete tear down then welded up with 4043 rod.

Yank the engine and start calling around.

Mistakes happen been there before. keep your head up!

Did you just tighten the piss out of the frame slider bolt?

It happened when I was lightly hammering the new frame slider bolt in. The engine dropped like 1mm as the new bolt pushed the original bolt out of the frame, then (I'm guessing here) the new bolt didn't go smoothly into the crankcase.

I'll yank the engine and ask around. Maybe just buy a good engine from a salvage.

That sucks a lot man. I'm sorry, I imagine you were hyperventilating a little at first. I know I did a couple of times when I had a SNAFU working on a bike like that. I'm interested to see how you resolve this.

Ugh, that's awful. Cast metal is difficult to weld, but doable buy a skilled welder that has experience with it. I agree, pull the engine and take it to a welder. I've seen used scrambler engines on eBay with $2,000 price tags, so it will definitely be cheaper to fix it.

OMG!
My engine dropped when I put my sliders in, I got the hammer out but decided to get the car jack out instead, sooooo glad I did. Hope you get it sorted.

The older I get the lazier I am doing my own mods. I don't mind paying for the shop most times. I guess there are some positive aspects to becoming an old fart.

Hello

Ugly situation...
In mechanic, hammer is not the right tool. If a bolt doesn't go in, you first need to check alignment of the path it should go through.

Welding the crankcase is not the solution in my opinion. The crankcase is part of the frame solidity on a Ducati, I'm pretty sure that it won't resist after welding. In your case, I would look for a replacement engine. If you find a working one, just replace yours and sell it in parts to be refund. If you find a broken engine, but with correct crankcase, replace your crankcase and sell the rest of the parts of the other engine to be refund.

FYI the Monster 796, and probably a few other Ducatis, the Monster 795, S2R, M800 and M800S, use the same crankcase which could make it easier to find a replacement.

If done correctly, the weld will be stronger than the actual crankcase material.

The entire frame is welded together...

So sorry about the mishap, man. This kind of stuff happens sometimes to those who are brave enough to do some work themselves. You'll be OK, keep the chin up.
