Case 222 Frankenstein PTO issues
I recently bought a Case 222 (serial 9736811 - built in 1977) from a guy that had several other Case tractors. I got it cheap, but it had some issues. The Kohler engine smoked like a chimney, so I knew I'd be rebuilding it. He threw in two mower decks and a snowcaster, as well as the mounting assemblies. I didn't know it at the time, but only one of the mower decks actually fit the 222, and the snowcaster is a G81, which also doesn't fit. So I got to work and rebuilt the Kohler. Works like a charm now. I combined parts of both mower decks and ended up with a working J44, which fits the 222 and that works perfectly as well (after some new bearings). Some hydraulic fluid leaks from somewhere, but a very small amount - not enough to cause an issue - yet. The last thing I need to repair - the PTO.
After internet search after search, I believe what I have is a Frankenstein PTO - parts from two or more variations of the PTO over time. The drive hub has a slot cut all the way around it for a snap ring to fit between the inner and outer cams. The snap ring was missing, so I ordered one on-line and thought it would work after that. It still wasn't working though. that's why i think I have mixed parts. So, I think my best bet is to simply start over. It seems like the best variation of the PTO is the EZ adjust nut and the outer guide nut. Buying an entire PTO clutch online is prohibitively expensive. So I want to try and make a drive hub. If I can do that, the only other parts I will need to buy is the adjusting nut and outer guide nut, which I can get for about $30. I am not a machinist by trade, but I do have a nice metal lathe and have made parts like this in the past (spindles, hubs, etc). All I need are exact dimensions of the part. So, I'm wondering if anyone here has that drive hub lying around that they could measure for me, or if there is anywhere on the internet I can get these measurements?
