Hello.
I have an ASR 33 teletype that I am trying to clean up and make it run
well. It does work. I plan to have it hooked up to a PC via a current
loop to RS232 adapter and have HeavyMetal feeding it text. It is very
dirty. I replaced the ribbon. Basically, here's what I'd like to know:
What parts need to be cleaned and/or lubricated?
How do I clean out the paper tape punch scrap container?
Can I use compressed air to remove dust, or would that cause damage?
Thanks much
Joe

only those that move
keep in mind, wd40 is very very light. It's not a suitable lubricant for many
applications. You think you have your unit all nice an lubed, but rapid wear will ensue.
Do a little research and find out what is a suitable lube for the type of metal/s and what
it's coming in contact with. Some plastics need lubing too. "Here we go looby lu.
la la la la" LOL LOL LOL

possibly. Compressed air is a resounding no no in machine shops. But I've seen at
least one production shop that uses it constantly. You may run the risk of forcing
something into somewhere you don't want it. But then that just might be an urban myth.
Chances are you won't hurt anything.
You *may* also consider break parts cleaner. It might not be friendly to all materials,
so check first. Alcohol, thinner, ammonia solutions, etc.

In fact the lubrication charts in the manual indicate areas that must be
free of lubricant (cotnacts, the type cylinder, etc).

is it? the WD40 we get ovr here seems to be a mixture of may oils,
including som that are more like waxes. The lighter oils evaporate,
leaving the wax behind. This is ideal for the intended application of
displacing water, but not good when it leaves a heavy waxy deposit on
small moving parts.

For th espeed an laoding of the parts in an ASR33, the type of metal had
no real effect on the lubricant.

Didn't we just have a thread on this? My recoemndation is uncharged --
strip the thing down, clean every part separately, put it back together,
lubricating as you go.
I asusme you have the manuals (they must be on Bitsavers). About half of
volume one is lubrication instructions. Do every lubrication point shown
there.
How do I clean out the paper tape punch scrap
container?
Is this something more than 'slide it out from under the base pan and
turn it upside-down over a trash can'?
Can I use compressed air to remove dust, or would that
cause damage?
I doubt that compresed air at a normal sort of pressure will do any damge
to the machine, but it will cause paper tape chad to fly around. If some
gets in your eye, you will regret it!
