My 1944 model A I'm currently working on came to me with a few "farmerized" additions. Most of which I'm guessing are from a late A or model 60.
It was a running and driving machine when I purchased it from a guy that deals in old tractors out of Wisconsin. It came to me with what I assumed was a 6V system. At least it had a 6V battery in it with a positive ground and 6V lights which weren't hooked up. The generator is 12V according to the tag though. Model number 00955 as best I can make out. What do I really have here? I'd like to change the whole system over to a 12V negative ground but what all does that entail with this setup?
I've also found the all to common worn splines on the clutch end of the crankshaft. They aren't quite as bad as some that I have seen though. I have a new clutch driver and it does fit tightly when installed but it fits tightly almost flush with the end of the crankshaft. I was pretty sure I heard that the driver needs to fit with a bit of room from the end of the crankshaft to the outer end of the driver when installed for proper clutch operation. Is that correct? Is it possible to gain that little bit by shimming it out with some thin material?
I may be moving soon and I'd like to have the tractor back together and operational by that point. I really don't want to tear it all the way down and find another crank for it if I can get by with what's in it. Its not a working tractor anymore so it wouldn't be pushed hard with this repair.
All thoughts are appreciated.
