[GreenKeys] Introducing Myself To The List

[Teletypeparts]

Rob,

Welcome to the list.  

You turn the motor using the fan.  Rotate the top of it towards the front of the machine.  It should move easily.  If you turn it backwards, you will encounter some binding even if all is well.  

You have done well already in removing the basic units for cleaning.  Just use 20 wt non detergent oil and lightweight grease in the few areas that might need greasing.  Mostly you will be using oil.  Most problems on old 33's are due to congealed grease on sliding parts.  

It sounds like someone sprayed contact cleaner into the reader and the wrong kind of cleaner will make the plastic disintegrate.  Unplug the reader Molex plugs on the back on the UCC-6 that go to the reader.  The tape reader, answerback and keyboard contacts are all in parallel with each other feeding the distributor, so a crossed contact in one area will cause errors even when using another one.  

Almost all 33 problems can be found by VISUAL inspection.  You have a good start on that already.  Look for keyboard contacts out of their slots or busted plastic where the springs connect.  Dont remove the keyboard cover unless the keyboard is installed or it will spring apart and you will have a basket case.  When you feel brave power up the machine in local and try typing.  

The pad is to collect oil and make the printer a little quieter and not essential until you get thru some other issues.  

Have fun!

Wayne

I have already had a couple of suggestions to turn the motor by hand. I tried that a few moments ago and it seems to turn OK, although I don’t know which way it is supposed to turn so I am wary of turning it too far in case I am turning it the wrong way and end up breaking something.
 
Regards

Hello,
My name is Rob Jarratt and I live in the Manchester (UK) area. I have joined this list because at long last I have managed to obtain an ASR33 Teletype, which I would like to get working. I don’t have any experience with restoring these machines and so need some advice. I have found some manuals online which tell you how to strip it down and what to lubricate, but there are still things I am unsure about.
I am told that this particular machine may have been in use up to about 1 year ago. I have to say that the main typing unit does look fairly clean. Are there any tests I could do on it without applying power to see if it is safe to try applying power? I would also like to know what kind of oil I should use to lubricate it, and any other tips on how to get it going again without damaging it. I would like to clean it all up too, but worry about dismantling the whole thing for fear of not being able to reassemble it or damaging or losing parts while disassembling it.
I did partially dismantle it, by removing the typing unit, keyboard unit, paper tape reader and call control unit out, so I could clean up the base and the outer casing. There was a foam pad under the typing unit which was disintegrating so I took that out and threw the bits away, it was also quite heavily impregnated with oil. I will need to replace that and a few other bits and pieces, some of the keys on the keyboard also seem cracked. I believe there may be sources for parts, suggestions for that welcome.
The paper tape reader and the paper tape punch don’t look to be in such good condition, and when I took out the reader I found various little copper bars that looked identical to ones at the side of the keyboard unit just stuck inside the reader, along with a number of little springs too. I am not sure if they came from the keyboard unit which is right next to it, or if they are part of the reader. I also found a piece of clear plastic that looked like it may have held the springs, but I can’t see where it came from. I don’t mind fixing the paper tape side at some future moment as long as I can get the typing unit and the keyboard working initially.
Any and all advice welcome.
Thanks and Regards
Rob
