FINISHED UP WITH PRINT CAM DETENT LEVERS
The usual formula - lots of Nye 140 clock oil and careful repetitive manipulation of each lever - broke up the sludge keeping the parts from moving. Once the levers were moving smoothly and restoring under spring power crisply, I set them aside to move on to the next group of parts in the printer.
ORDERED MORE OIL
My clock oil is down to about 1 ounce and there remains quite a few parts to loosen up. I am going to need to get more. I placed an order and hope to have it within a week.
REMOVED DRIVE BELTS TO WORK ON POWERED PARTS
I loosened a pulley to release tension on the belts and take them off. One was previously identified as shot due to a cut but the other one looks a bit rough and is deformed from sitting in that position for decades.
CHECKING TO SEE WHAT PARTS CAN BE ROTATED
The first drive belt ran from the motor to a pulley. The second drive belt goes from that pulley up to the Print Clutch Shaft. It has a gear on the end of it which meshes through a neutral gear to drive the Print Wheel gear. With them all connected, I couldn't get anything to budge.
By disconnecting the pulleys I found that the Print Cycle Clutch shaft and the Print Wheels turned relatively easily. It was the motor itself that had enormous drag. I could barely turn it at all by hand. My suspicion is that the grease has degraded in the motor bearings, but we shall see after I pull it off the frame and examine it more closely.
STARTED WORKING ON THE PRINT CLUTCH RESTORE LEVERS
These where the most frozen parts of all in the machine. I had to flood the slots and pivot points, then force the part to begrudgingly move before I could work the old lubricant out. It was one by one, sometimes two at a time, a very slow process. Once freed up they moved nicely.
