PTO is reassembled today. I used a very small amount of auto grease on the end of an exacto knife to place the bearings in the race. Of course, I did it three times because, if you leave the dial on, both the 'stop' rod and the idler rod for the plastic gear must be in place BEFORE you reinstall the Dial Shaft and Bearings. As I had not soldered the other end of the braid I put a hole in the end of the braid and tinned it. The other end of the braid went under one of the screw heads that holds the circuit board down. Hopefully this will work fine. The excess grease (of which there is hardly any) was wiped off from around the bearing race. There were ten balls in the race.
Hooking up the PTO yielded a signal on the counter and I ran the dial back and forth several times adjusting the 'stop' point until the PTO was covering 4.9 to 5.5. The gears feel good and the stops are working at the correct points. The PTO seems ready to go back into a radio. I have three more I could and probably should do but the TR-4 has a 'Jumpy' PTO and my original intent was to just swap this one but I may tear it down after I pull it and see if I can give it the same cleaning and reassembly and see it it improves. Put a few more pix of it on the blog.
