Some prefer TIG and other MIG (metal inert gas was invented to weld aluminum). The joint preparation is crucial, well open joint, preheat and clean. During welding, making sure dross are remove prior to deposit a new weldment. Dont over heat the joint during welding help prevent hotcracking. What is the most omitted is aging after welding. Aging is accomplish by holding the part in an oven at 350 F for 12 hour. Slow cooling and let alone for a couple days, in a sunny place. After this, machine the casting. The aluminum need to relax itself before being put to stress; bolting the part together, inserting a bearing or machining inducing stress. You patience will be rewarded with a good solid job.

I will need to machine an aluminum collar, if you will, to slide over that counter shaft piece and weld that in. Then, make a solid plug to fit in the speedo hole & weld it from the outside. The main shaft hole has nothing done to it, other than being welded to the c/s collar.

Am I looking at this right?
Theres a photo of Monte's bolt on steel type ring in this thread:
http://www.xlforum.net/vbportal/foru...1347604&page=2
I cannot find the photo from the outside, possibly he can redirect or post pic.

Please jump in if someone thinks Im missing something.
I believe its the fit between the new ring outer face and the radiused wall that makes it stronger, these need to be fixed as one. This area needs more case surface area to support the load.
Take a look at the your non repaired c/s bearing boss, its only maybe 3/16" wall and protrudes toward the trap door. Thats alot of overhang and possible leverage that can bust that corner.
The only meat supporting the bearing/shaft is the perpendicular area of bearing boss to the case wall. So making this overhang have more support radially is the way to go.

The bolt on ring may be easier for some machinists or shops.
Some guys are terrified of welding aluminum, not all machinist can weld and not all weldors can machine. You need a guy that is proficient at both.
Just giving you an idea of options.

There is a threaded plug you can install in speedo hole: http://www.ebay.com/itm/SPEEDO-BLOCK...#ht_665wt_1348
I think the real issue is the c/s area.
Anyone else think the speedo hole should be welded?

See how strong the factory made it w/ no speedo gear relief (newer gen. case):

Exactly. Think of it this way : the gears are trying to spread the two shafts apart. The more power you transmit, the more they will try to spread. For regular use it's probably okay but say you go over some railroad tracks or a slippy white line while you're on it. The wheel spins. You get sudden traction on the other side. Wheel grabs. Wham ! Loads go to the moon. Case breaks.

So anything you can do to support the bearings against spreading will be a help.

That's what needs to be done for a never-worry-again fix. The closer you can get to that the better. Or just ride it more gently. People drive MG TC's around without fixing all their weaknesses .... carefully
