Iv finly worked my way back to the P.T.O. / belt pulley attachement on my "A" in this little restoration project and and am stuck on a problem. This is a 1940 model and has a different P.T.O. setup then the latter A's. How is the gear oil supposed to stay in the belt pulley box? The bearing I took out (the one between the pulley box and the P.T.O. box) is not sealed on one side. It looks to me that when opperated, that the pulley box oil can run through the bearing and into the transmission, and possibly starve the Belt pulley gears for oil. I bet those 2 bevel gears can really sling the oil when running.
The original owners manual doesnt have a section on the P.T.O. as it was an option, and the I&T manual is kind of vauge. The IH bearing # crossed over to is a 206-J which is an open bearing, no seal. The latter style box that I have also doesent have a seal on it, but has a hole through the case between the transmission and belt pulley box, and no slinger. The `40 style setup has a big wafered oil slinger disk bolted to the front of the P.T.O. shaft to help keep the transmission bearings oiled when the tractor is stationary and using the belt pulley.The latter style transmission doesnt have this slinger, but instead has a "oil roller gear" mounted on first gear on the lower gear cluster. (I updated the transmission to include this gear.) Does the waffered slinger help pass oil back through the bearing into the belt pulley box? Or do I need a special sealed bearing? If any one has a parts breakdown for an early "A" P.T.O./ belt pulley setup, could you please post the belt pulley box bearing numbers for me? Or if you have had one of these early box's apart for a rebuild, what was in your box? Thanks for your time. Steve T in MT

Pitfalls of Tractor Engine Rebuilds - by Chris Pratt. The first pop after you have put the machine together with your own hands is exciting and pleasing. The whole experience can be marred if one moves too fast and makes too many assumptions that they can just use "as is" some parts they should be closely scrutinizing and possibly attended to. In such cases, rework makes what could have been a fun project turn into an irritant or even a nightmare. Minor Irritants To give you an example of an minor but irritating proble
