In case there's interest here's a pictorial of the Sherman install that consumed a bit of time over the past few days -
I have a TO30 that needed engine work that necessitated pulling the engine - I had scored an Sherman combination 3-4 years ago off of eBay and had cleaned it up, inspected, and procured a few minor items (shims and gaskets and a seal) in case this day would ever come -
engine pulled, I went ahead and removed the steering pedestal, starter mechanism, brake and clutch cross shafts, and input shaft to clear the area - nasty oily (leaking rear main seal on the engine) - I later went ahead and pulled the shift cover so I could see what was going on with the preload on the bearing
a quart of kerosene and half a can of brake cleaner later and the area was fit to work in
The mounting flange and shims and gasket - to make a long story short, I didn't need the shims and I also made a gasket out of thin material to get the input shaft acceptably close to the bearing
flange installed and Sherman about to be bolted into position
after a couple of times in and out I tightened things so to locate the shifter hole - I was worried about this aspect, large holes in heavy metal is a weak point in my skill set -
I used a bit of angle iron and machinist square to locate the center of the hole
removed the transmission again and drilled a pilot hole and then went with a bimetal hole saw
I was pleasantly surprised at how straightforward/easy it was - I cleaned up the hole with a grinder, shot a bit of gray primer on the area and put the Sherman back in position - I'm satisfied with the result
for future reference, this hole is centered at 2-7/16" down from the pedestal machined surface and 14-1/8" forward of the transmission flange
filled with GL-1, new seal on the input shaft, shifter in position - the Sherman and the piece it replaced -
tomorrow I'll put the starter (needs work) and cross shafts back - also trying to move ahead on the engine...
