[GreenKeys] Model 28ASR in Texas - typing unit

[Kevin H. Phillips]

Attached are some before and after pictures of the typing unit. All I 
have done thus far is clean it; I have not started re-lubricating it.  
Looking at the first picture you might understand why I almost passed on 
this deal when I first opened the cabinet and saw the typing unit in 
this condition.  But, I decided to take a chance and give it a try, 
hoping that most of the rust and dirt was superficial.  For once in my 
life, I seem to have been right.  What I did to clean it was give it a 
brief soak in a vat of Simple Green (I have a large plastic storage bin 
with several gallons of the stuff in it which I keep covered and use as 
needed).  I also bought a small 1/2-gallon pump garden sprayer which I 
filled with Simple Green and "fired" it into the hard to reach spaces to 
try to give a little pressure to the solvent. Then I washed it off with 
a garden hose with a spray nozzle, then I dried it  in the oven.  Many 
of you know just how excited wives get when you use household appliances 
for Teletype repair.


The stunt box does not seem to be heavily populated.


I also used a little Naval Jelly in spots to remove some rust but you 
can still see some on the main shaft.  There are also springs which have 
a little rust on them which worries me a little.  I intend to hit some 
of the high spots with Scotch Brite pads and penetrating oil.


When turning the motor and shaft by hand, the typing mechanism seemed to 
rotate and the typing head moved along as it should so it seems that 
none of the mechanism was actually rusted to the point it would not move.
