[GreenKeys] Need ASR33 repair help, in Ann Arbor MI

[Teletypeparts via GreenKeys]

Keith,

I dont live near your location but I can give you a few tips.  

Dont type too much without inspecting the rubber hammer that hits the typewheel.  If the rubber hammer falls of or disintegrates you will ruin the typewheel quickly.  

Most 33 troubles can be found by visual inspection.  No adjustments unless you have exhausted the visual stuff.  Look for things out of place like contacts in the keyboard, tape reader and answerback.  

There should be nothing in the machine that needs force to fix or correct.  Go slow.  

33's that have been sitting a long time usually have congealed grease on the codebars and other areas that need freeing up.  The codebars ride on slotted round bars on each end and in the middle.  I use "Breakaway" in those areas very carefully sprayed on.  Very Carefully!  

Dont spray any solvents into the keyboard contacts or other plastic contact areas.  Use a pipe cleaner with some contact cleaner sprayed on the pipe cleaner and clean carefully.  You may not need to do this.  Remember that the kybd, TR and AB contacts are all in parallel feeding the distributor.  Thats why its good to be able to test the printer from another source before assuming that you have printer problems when the problem might be in one of the three subassemblies that feed the distributor.  

Most 33's come with 20 MA full duplex (4 wire) setup in the UCC-6.  You need a current loop to RS 232 adapter to connect to a computer.  Some computers have a current loop interface in them.  PDP's etc.  Ask on Greenkeys.  

I will include some pics that might help identify stuff.  

Happy Thanksgiving from Vermont where we have 4 to 8 inches snow overnight.
