Freeing up 1132 printer components - part 3

FINISHED PRINT CLUTCH RESTORE LEVERS

I put in a couple of hours to free up all the parts of the Clutch Restore Lever assembly. They were stubbornly frozen and had to be handled a few at a time, using copious oil and lots of repetitive movement. By the end of the session I had them all behaving properly.

These levers are pushed by the lobe of each Clutch Print Cam. They push the Clutch Trigger and Armature Knockoff levers back into their idle position. 

WILL MOVE ON TO FREE UP THE PRINT CLUTCHES

The Print Clutch rotates freely around the Print Clutch Shaft as long as the tooth of the Print Clutch Dog is held away from the flutes of the rotating Print Clutch Shaft. In the idle state, the dog is held by the Clutch Trigger lever, sitting on the Armature Knockoff lever after being restored. A small notch on the outside of the Print Clutch is held by the Print Clutch Detent levers, so that they don't rotate around from vibrations even though the dog tooth is not engaged. 

The Print Clutch discs are stuck to each other by congealed lubricant. Some of the dogs have slipped off the Clutch Trigger, with their tooth jammed onto one of the flutes of the Print Clutch Shaft. The dogs pivot on one end and are pulled into to engage with the flutes by a spring. 

I need to lubricate the Print Clutch Dog pivots, then free up the clutch disc plates so that they all spin freely when not engaged. I have decent access to them from the top of the printer without disassembling this part of the mechanism. 

However, some will not remain free of the Print Clutch Shaft flutes because the Clutch Trigger is frozen in the wrong position (tripped). I will have to loosen up the triggers. Not sure yet how I get access to them - whether I need to remove the print wheels which is a big hassle.
