Working on cleaning and refurbishing R-4B s/n 15533B, I removed the PTO and started to clean and re-lube the bearings. After some 3-in-1 oil and Rem Oil in all the usual places, it was still a little stiff, so I removed the cover and started backing off the tension adjustment. I now know that it doesn't take much tension removal to make the ball bearings start dropping onto and rolling about the table! It was a bit of a bear getting them all back in, but about 20 minutes later - mission accomplished. It's tuning smoother but I'm still feeling some roughness when turning it by the shaft. I suspect the action will be easier with that big knob back on it.
Watch the bearings when adjusting tension! The R-4B has been washed on the top only, rinsed with distilled water, air-blasted and is now sitting in its sauna in the kitchen, where I'm keeping the temp at around 140 to help with drying it out. It will get re-capped over the coming week. 73, Steve Wedge, W1ES/4 To be is to do - Socrates To do is to be - Plato Do be do be do. - Sinatra All my computers have my signature with various pearls of wisdom appended thereto.
