TOP COVER REATTACHED
The top cover went on next, hinging at the rear and held open by a dashpot and lock plate. The dashpot moderates the rate that the cover closes.
ORDERED NEW RUBBER DRIVE BELTS
The motor to pulley belt is a 34 1/2" x 1/2" V belt and the pulley to clutch pulley cam shaft belt is a 36" x 1/2" V belt. I ordered one of each from Amazon and had one of them when I returned from a week trip to Rhode Island; the other will arrive in a few days.9
DEALING WITH BROKEN GLASS ON TOP COVER
The printer had a glass window on the top cover, but it had been broken prior to my receiving the equipment. It won't be a complicated repair since it is a simple rectangle shape, I just need to measure, order and install a replacement. In the meantime I installed the top cover to complete the reassembly of the printer.
GOT MY PCB TO REPLACE REED RELAY ON THE SIDE PCB
One of the three reed relays on the printed circuit board mounted on the left front of the printer frame had an open coil. I bought a pair of reed relays that will fit on a small daughter PCB I will mount above the IBM PCB to replace the functionality. The remainder of the IBM PCB works properly and just needs to be mounted and connectors attached once I finish up the daughter PCB connection to the IBM board.
WAITING FOR REPLACEMENT RIBBON
This printer uses 3/4" wide black ribbon wound on open spools. Each end has a rivet that will trip a reverser so that when the end arrives as the machine winds in one direction, the reverser begins using the ribbon in the opposite direction. I have to buy an inked 3/4" ribbon, put on the rivets and attach it to the IBM spools. I found a supplier who provides as many yards of 3/4" ribbon as I wish. The original IBM ribbons are 18 yards long.
AWAY FOR A WEEK
I am away for a week visiting my daughter, but that gives time for the drive belts and some other things to arrive for when I dive back in early next week.
