Well, the Super M transmission sub-project is now officially out of hand! Pulled the top plate just to give it a good cleaning inside and check things. Then the "might as well"'s started. .
Now that I'm in one of these, it's not hard at all to work on. I'm thinking about pulling things apart and completely going through it. I've already got new axle, brake and PTO seals.
When I had the bull pinions in hand I noticed that the bearings had some play in them. Is there a way to check and quantify play in ball bearings? Obviously there has to be some play or they won't roll. But other than obvious mechanical damage what is the best way to check for wear?
Also is there a tolerance or spec for play in the input shaft pilot bearing? I couldn't find anything in the I&T manual. I haven't put a dial indicator on it, but my built in hand indicator feels like it's at about 5 thou.
It's my understanding, too, that the bull gears are symmetrical and can be swapped from side to side so as to run on the less worn side. Is that true? Can the bull pinions similarly be swapped side to side. That should put the teeth face that were reverse to run forward and reduce play, right?

To top that off, you have a cup with oil in it ("why would you want to lubricate your carburetor?"). On closer examination (and some reading in a AC D-14 service manual), I found out that this is a pretty ingenious method of cleaning the air in the tractor's intake tract.
