Reassembly of the 1132 printer - part 1

BEGAN REASSEMBLY OF PRINTER MECHANICAL PARTS

I began assembling onto the frame the subassemblies I had worked on. I first installed the Print Clutch Cam shaft onto the machine with the Print Clutch Cams all resting in their idle position. This is where they will sit if the Print Clutch Dog is held out of the shaft flutes by the Print Clutch Latch lever. 

The cams are separated by the comb slots of the guide I inserted while working on the workbench. When I put the Clutch Print Cam shaft onto the machine, there was another comb guide at the bottom into which all 120 cams had to fit. This was a very slow and tedious process, taking about an hour of time to move them carefully to fit into the comb teeth before the shaft settled down in place on the frame.

A couple of Clutch Dogs popped off their pivots

In the process of getting the cams into the bottom comb and installing the shaft, I ended up with a few of the cams rotated compared to all the others. I also had a couple Print Clutch Dogs pop off their pivots, which I will have to resolve with a 'laparoscopic surgery'. 

I finally had the full set of cams engaged in both top and bottom combs. A third comb was added at right angles, but that was a breeze now that the top and bottom of the cam disks were properly spaced.

Third comb bar added to further stabilize the cams

I installed the two bearing caps and tightened them down. There were a number of restraining screws to reinstall that keep bearings from walking out of the side of the frame.

I then reattached the ribbon mechanisms and other parts that had been removed when I took the bearing caps apart. The left and right ribbon mechanisms are connected by a bar that runs through the print machinery, between the Print Clutch Cam shaft and the Print Wheel Drive shaft. I got that squared away.
