Not sure exactly how it happened, but a rock is the culprit.
The outer chain guide case was crushed, and I bought an OEM replacement. But when I mounted it all up, the alignment is off, indicating that the mounts must have been bent in the process.
I can't tell how much its bent, or if its the front, rear or both. Possible bent both up and in.
Anyone had to massage these back into place? I'd appreciate any suggestions.

Looks about right to me so I doubt it is that far off - the sprocket should line up with the center of the guide. You can just use a hammer to bend it back.

Thanks Riddler.

You are right, it doesn't look too far off, but I can't find a good view on line of what that mount looked like before we bashed it to know how far off and in what directions it needs to come back.

Rotating the wheel, it's definitely pushed in, but almost more it seems like its pushed up too as it wants to pull the rubber guide out the back.

Pulling or BEATING it back downward is a little more concerning to me than straightening the mounts vertically.

The persuasion technique is at the top of the list for now though...hopefully its close enough that it wont take too much...like you said.

Rather than bashing on it I would try to use a bar or lever inserted in strategic spots to use leverage to control the realignment.
Pry bar, tire tool or just a round piece of bar stock.

Take it real easy.

I would be careful bending and beating on that aluminum as its very soft and prone to crack, also when you stretch any metal you change its properties and it will never be exactly where it was or as strong. meaning It will never make the same shape it was and will either snap off or bend very easily next time you bash a rock. worth a shot to get you by and the worst you'll have to buy a new swing arm or pay a machine shop to make a billet one and weld it on for you. good luck with any way you go about it.

I agree with HP - Be careful & use finesse.

If it shows signs of cracking of does happen to break, it is easily weldable.

Good luck & just take it easy.

Thanks for the replies.

So last weekend I figured it had to get fixed, for better or worse, so I took the wheel off, strapped the bike to a post, and put a bit of heat to the mount. I have a wide punch that I wrapped with some rubber around the bottom (an old vacuum cleaner belt) just to try and minimize excessive galling...and proceeded to persuade it.

Honestly by looking at it I couldn't tell if I was moving it at all, but when I put the wheel back on it was good enough. Still rubbing the side of the chain guide a bit, but it'll do.
