Having completed the PTO shaft, I turned my attention to the gearbox as the drive collar was sill in place but had been soaking with daily applications of WD40 and similar penetrating fluids.
This did the trick and with the threat of a copper mallet and an even bigger drift, the collar seemed to jump off without much of a tap? Surprising considering the resistance it gave last time.
As can bee seen in the photo, a repair is required to the collar and the picture shows the steel I plan to use.
I used a different piece of steel that was a little wider than the piece I first planed to use. Having scribed out the sizes I drilled (using my restored Mancuna B2 hand drill) the first hole with the biggest drill bit I have, 15mm and then preceded to hand file the rest using the pin as a guide until I has happy that the correct roundness was achieved.
I then measured where to cut the steel such that it would match up with the break on the drive collar and allow the pin to fit.
I cut long allowing me to chance to file down until I was happy with the fit, which can be seen was not a square fit. I had to adjust each side of the hole to get a good and level fit.
Once the fit was where I wanted it, I beveled the edges so that when it is welded, the weld will fill in the join rather than just on the surface.
Hopefully, when it is welded tomorrow, it should appear to be one piece?

Glad you got it off. Check to make sure that the pin is snug in the main hole next to the wheel hub and if you can make the hole where you weld the new ear on a very loose fit around the pin. The reason I mention this is that I repaired a hub on my 1050 about three years ago using a similar method and the ear broke off again this winter one morning while I was blowing snow - wondered why the tractor quit moving as the pin had slid sideways into the free wheeling mode. The reason I think the ear broke was the pin on mine was a little loose in the outside hole next to the wheel hub and worked sideways against the inner ear hole every time I backed up or went ahead causing undue stress on the ear where it had been welded on.
