IBM center pulley

I remember seeing a couple of "in-machine" fixes for the center hub, and I thought I copied and saved them, but I can't find them.

Thanks I'll give them a call and see how much they cost.  The customer might have us order them one.  And I might order one for mine too.  I have one someone game me that all it needs is a steam cleaning and complete pm.

On a similar note.  Does any one have a platen for a 15" selectric II?  Have a customer that doesn't want to give hers up. And the platen in her machine is so worn you can almost comb your hair with it. So I am looking for one, new or recovered doesn't matter.  Or even a source for one.  Can't seem to find Tech Support Associates anywhere.  That's where I used to get recovered platens years ago.

OK.  Here's what I did. I got a radiator clamp, the one with the screw-type tightener, cleaned it, and glued it. Stay tuned. I actually can replace the hub reasonably quickly, but I like to solve puzzles.....
Anybody have the hubs?

If I remember the procedure it involves a bit of wire and some two part epoxy glue.  Slip the drive belt off of the pulley, just don't remove it.  Mix the epoxy and paste it into the cracks.  Wrap the wire around the inner hub and use a pair of pliers to twist the wire tightly around the hub so that the cracks in the hub close.  Just make sure that you don't put too much epoxy in the cracks.  Trim any excess epoxy off of the pulley.  Let sit for enough time for the epoxy to cure and slip the belt back on to the pulley.  I have tried this two times.  It held up once for six months and the other the pulley teeth were too far gone and broke anyway after a few days use.  Truthfully I only tried this repair because I did not have any new pulleys and the customers needed the machines right away.  If I had had the pulleys I would have replaced them.  It takes about the same amount of time to do the repairs either way.  But then I replaced dozens and dozens of the pulleys on Remington SR101's in the seventies.  The Remington's were assembled in two countries back then.  The ones from Holland were almost as good as IBM's.  The ones from Italy were fairly good boat anchors.  Which is why I had to replace dozens of the pulleys in the beasts.  They had cracked center hub pulleys regularly within two years..

I hope somebody responds to this with an easy answer.  The last one I did was 5 or 6 years ago, and altho I still have one hub in stock, I told the last customer that I would rather refurb another machine for them than replace that stinking hub.  I even asked the guy who taught me if he would do it, and he said NO!

Thanks for your response.
There was a fix I saw here that just involved a little glue.  Anyone?
