The chain broke and whined it self up in the case. Don't know why the selector house broke because of this. One of my engineering friends said they can weld it for me, Has any body done something like this before?

that blows man.. i have seen someone do a nice pyramid weld on that spot and made it work for a while.. in the end you are going to need a new case unfortunately :(. before you ride again i would look into getting freek to hook you up with a case saver if he currently has any. it even protects that shift shaft where yours is broken.
 
damn that suck, you could repair it to last a little longer. but it would be better to get new case. and yes that is why you get a case saver.
 
Would love to get one from freek but i wonder what would postage be to here? It can't be to much normal postage would do i think!

hmmm, i know the case savers themselves are $30 shipping to SA is no tgoing to be cheap im sure. BUT it will be cheaper than haveing to fix another busted case. im imagine if that wasnt repairable, alllll those bearings and seals would need to be changed to a new case, crank swapped over..
 
I would think if you took down your cases and pressed out the bearing and seal and had the case mocked up properly a good welder could repair that case completely and maybe even lay down a little extra filler rod to strengthen that area.

Unfortunately, it will require you to completely tear down your engine to repair and the common logic is, it's complicated and costly to tear it back down if the repair doesn't hold do you want to chance it?

The only problem is, you live in SA and getting parts might be a little fun (and expensive) Repairing it may be the only viable option depending on how your finances and parts availability are. If it's done right, it should be able to be repaired.
 
That is true, i phoned a MX Alliance(direct importer) and he said i will get a new price list for tusk and other people tonight. So i hope there is some nice one nearby to buy!
 
It's is repairable but by the time you break it down and pay to fix it you mine as well buy a new set of cases.
 
dual, I would agree with you here in the states where we can just find someone on the BF who can pop those new cases right over to us using USPS.

In his case, it might be different with increased shipping rates, duty taxes, exchange rates, and shipping delays. Especially if he knows someone who has a TIG welder and some time who can put it back together he may be better off repairing that case.
 
To break it down and reassemble it is not the issue, done it before a few times, The welding is also not going to cost me much my consern is only if it will work. If it would i will firstly try to fix it and then replace it

You are probably correct,I forget he lives in South Africa.lol Time to weld it up.
 
In summation; the transmission case is not under pressure from the fluid, only when you shift gears. There is enough aluminum in that area of the case to work with that it can be repaired as long as the weld is done properly.

Tear the engine down and remove the bearing and seal from around the shifter. Clean everything very well with some mineral spirits before starting the weld. Don't use tetrachloroethylene (brakleen) to clean the cases:

Brake Cleaner = Phosgene Article

If your cousin knows what he's doing he'll pop a few parts together to align the broken piece and then you can reinstall the shift rod to check alignment before he finishes with the filler rod. Once everything is all beautiful leak check it before reinstalling in the frame. If it's a tiny seep you can use some epoxy putty to fill in the hole if it's a huge leak I would question whether the weld is strong enough to hold against the abuse. As long as everything turns out ok a repaired case should be 95% of the strength of the factory case and it took your chain exploding to mess up the factory!

Oh, replace your chain while you're at it LOL
