Folks,

You must be talking about me - I am still here!

I will still work on them free except for parts.  I am retired and enjoy working on them but I am not in the business.  So I will not commit to specific delivery dates. I can be predictably slow at times.

They are not very difficult to make operational but most need lubrication, cleaning, and some adjustment.  Like an old clock! But parts are hard to come by.

The big problem with your original machine was weak magnets in the selector mechanism.  They had to be replaced to get it back to good functional specs.  I think Paul Kleinschmidt (sp) provided the replacement. 

I will help if I can.  Best to use email to contact me.

Mark, 

The shaft under the moto drivs the keyboard.  If it is turning you should be able to transmit.

The grinding you hear may be from the function clutch , behind the ribbons.  It has teeth that engage the two halves of the clutch, but some times they don't disengage fully, making a grinding sound. There are two arms on one side of the clutch. One should hit a ball  bearing to disengage the clutch..

Try to push on it to fully disengage the clutch

Good luck

Subject: [GreenKeys] TT-76 Help/Howard Weeks

It's been 10 years since I last had a TT-76, it was in a GRC-142 shelter which I sold about 10 years ago.  When I secured a TT-76 for it I put out a call for help on here and I believe his name was Howard Weeks responded, I shipped it to him and a short time later I had a 100% working TT-76.  I hope I have the name right, it's been a while, I think he was from GA or nearby.

Well here I am again with another GRC-142 and a sick TT-76, the motor turns and I am able to adjust the speed but it sounds like a meat grinder instead of just a motor hum.  I lightly touched up the bearings with some Kroil and it did not change.  When I type I get no response, I do see what looks like a clutch linkage front right just under and left of the motor closing when I type so it's doing something.

This machine is really out of my area of ability and I am hoping I can find MR. Weeks again or another to get it back up and running again.  I have the UGC-74, radio's, modem etc all working again.
