Trivia - found these old blueprints, probably some of the few that survived if not the only ones, maybe Alan Jones has a set, of the AC power train .  Note the original units had a release bearing  and clutch in front of the power .  Trivia FYI.

Just to set the record straight, this is the 7010 and up 6-speed Power Shift transmission, not the model 7000 tractor. I'd like to see a date on this too. Might be from the 7030/7050 prototype era ??

My 7060 PS takes off very smooth in 4th low or high range and and first high and low. Second and third are really jerky and erratic as the pedal is let out, I think it has to do with the way the valve body is made or designed or maybe adjusted. The operators manual says always take off in first, but in low range this seems too slow and taking off in fourth low is smooth as can be and it is a good speed to start hay into the round baler. I wonder if all the 7010 and up P/S trannys act like this? The dry clutch in front of the P/S might have let you take off smooth in any gear. Definitely a great find and a mystery drawing.

I would think all of the plans are at the patent office?
I see a lot of their early stuff on there like the Mills.

If I'm looking at this correctly, this appears to be a cold weather disconnect so that you could start the engine without hydraulic and transmission drag. You wouldn't want to use that in normal operation as you would lose all hydraulics(steering and brakes)and PTO.

actually the blue print stated , in hand written numerals,  6/29/72 and some material sheets are dated 1971..   the first power shift units were assembled in 1974 and tested in 1974 and 75 - the 76 7040 and 7060's  - (small filtered power shifts - some may have been built in 75?)   1977 units had the larger filter for the ps.
