Finally finished and all reassembled, no leaks after re-filling the transmission with 90wt gear oil, 1 1/2 pints. Probably should add the remaining other half pint to accommodate the PTO? Anyway, thanks for all the help with this little project, on to other needs of this old but very nice truck e.g. terrible steering, etc.
Just so you know, I searched high and low to find any truck co., any alleged PTO restorer (many advertise, few interested in, capable of delivering any old truck service), anybody who was capable of giving this particular PTO a rejuvenation, and I finally found one. He and the trucking company, in business and wrenching since way back when these units were still relatively fresh, have the necessary experience, memory, and resources to refresh an old PTO, with a welcoming attitude ("sure, send it up here"), and, in their words, "gotta keep these old trucks goin' ". Fun to work with, not in a hurry, lots of resources, and at a price very affordable to me. Some good people out there.
