Dont forget to use nickel welding rods

Ummmm.....



I haven't quite given up on opening the box, it just isn't a priority for the moment.

I ground the shaft flat with a view to drilling it out. I figured that if I drilled it out I can get a stepped drift in there to help aim the blows better without mushrooming the end.

I'll try the propane torch though.

No time now until next week by the look of things.

That hub looks like cast iron so you'd use a nickel or 29/9 rod to weld it.

Have you tried differential heating and cooling? Dry ice on the shaft and a propane torch applied carefully to the case

Not yet.

I think the plan will be to bore a large hole, 10mm, through the centre, heat the case and then quench the shaft from the inside with a can of WD40 or a squirt of water.
I will need a drift with a reduced shank made ready to drift it out quickly.

I managed to drill out the shaft. I decided to drill off centre and open the hole out until it split the side of the shaft. It came out quite easily then.

I got the box opened up, spilling a bit more paraffin (kerosene) and mayo on the floor.
It looks ok.



There is a very small amount of rust between a couple of the diff gear teeth and a little on the gear cluster shafts but nothing that would affect function.

The teeth are showing a little wear but again nothing that I can go much about and nothing that is threateningly bad. The half shafts are showing a little pitting on the outer ends where the needle roller bearings are but the rollers look fine, I suspect they have been changed at some point.

It should last a while and by then I would have another solution. I'll most likely have broken it again doing something silly!

I have stripped as much as I can, cleaned and lubed and reassembled the box now. I made a paper gasket to seal it with but will need to find a Wheelhorse dealer to get a couple of axle oil seals.

So far so good.

I've had nothing but grief from home-made gaskets and not much better from store bought paper gaskets. I use Permatex Copper Formagasket now for almost every use but high temp applications.

Woody,

Now thats the Woody I know, I knew that you couldn't pass up a challange like this. Didn't think about drilling off center, I'll have to remember that one.

I feel much better that the internals are in reasonable shape for something that old. I wish my internals were were as good as those parts look.

It looks like a lot of the pieces you built for the other trans will mount up without too much work needed. Save a bit of work.

I'll be watching over your shoulder.

Jim

PS if you can't find seals let me know, my buddy might have some plus there is a dealer near by.

I've been lucky so far with home made gaskets. The plan is to add some kerosene and see if it wets the outside. If not then I will drain and add gear oil. Need to check what sort.

It sorta dawned on me as I thought that if I drilled a central hole and it was still stuck I would saw a slot to split the tube. It then seemed sensible to 'split the tube' intentionally.

I'll bear it in mind about the seals, thanks Jim.

Hi Woody

need to find a Wheelhorse dealer to get a couple of axle oil seals.

Have you tried your local bearing supply house? -these things are almost always standard sizes

Designing with a non standard size seal leads to the design engineer being fed to the wild seals

Big engineering companies keep a tank of them ready just in case
