250r case repair

[myles]

I have a set of 1985 250r cases, each side case on the inside between the crank, and the counterbalancer has a notch knocked out of it about 1 inch by 3 inches. I have a guy that says he can repair them by building up the hole with a tig welder I believe, and then grinding it into shape. I told him that I have an old case that he could cut the pieces out and weld into the notches, but he said his way was better. I'm just worried about him ruining the cases. Does anyone have any experience doing this, or having this kind of repair done for them?

That is a perfect example of why you should change your counter balancer bearings when you change crank bearings...cheap insurance. No, pooling the weld will not be the correct fix. It is better to cut those areas square and graft in new aluminum, seam weld and grind back out. I have a really good fabricator that could do that.

I had BDT fix mine.They did a great job.

Yes I agree 100 percent on the bearings, bought the cases like this. I'm no welder, but I think grafting a piece like you say, would be the proper way to go. Thanks

Thanks atc300r, but I think the shipping cross border and back, plus the repair would be really expensive.

Hopefully you can find a good welder locally, then you'll have to have them machined.

FYI: Guys that weld boat propellers are second only to certified aircraft welders and a lot easier to find locally. They are also usually better at dealing with the impurities found in used aluminum.

Good luck!

I have welded plenty of them and if a guy knows what he is doing, that isn't a tough repair to do. You can do it without an actual machine process. File off the tall part and then sand paper and a flat surface to lap it in.
