[GreenKeys] Refurbishing a KSR-33

[Teletypeparts]

Chris,

Where to start....

Cleaning the plastic cover, use 409 or Fantistic and your fingernail on the stubborn parts.  Get the real stuff, not the kitchen version.  Degreaser carefully on spots as a last resort. 

Changing the fuses to breakers is probably a waste of time as they dont blow that often.  Your time better spent on other stuff.  

Cleaning inside.  Degreaser sprayed carefully in the printer only in small areas at a time and wiped clean or blown out with air.  Dont spray on or near any plastic parts or contacts.  Breakaway sprayed on sliding parts will free up congealed grease which is a problem on many machines now due to age.  Lube felts and moving parts with 20 wt non detergent oil unless you have something better suggested.  

Changing a KSR to an ASR means lots of parts, new cover, new pan, punch, reader and many small parts on the printer.  Not too practical.  

There is no real great need to change the motor start system once you get it working correctly.  Only the start cap and relay are needed.  Again better your time spent on other issues.

73's

Wayne

Firstly, thanks to everyone who has responded for all the helpful
nformation.
I have no plans to muck about with the keyboard of my KSR-33, it's fine the
ay it is right now. (Little cleaning with a q-tip and some rubbing alcohol
on't
urt it, will it?)
I've managed to get the carriage returned; with help provided in that
epartment
y Mr. Dave Hunter. Though I've yet to get the system up and running to see
f
he carriage now travels freely.
I'm also handily getting a set of manuals on CD from Mr. Jim Haynes which I
m
ery thankful for, as well as a scan of the Model 33 training manual from
r. Don
obert House.
The issues with the motor burning out the fuse have been clarified by many,
specially
elpful has been Wayne. I'll have to take a look-see when I can get some new
uses.

ow, for a few questions. Firstly, would it be possible/advisable to replace
ll the fuses
nd fuse holders on the teletype with equivalently rated circuit breakers?
nd further,
ould the start capacitor for the motor be replaced with a modern
quivalent?
I ask about replacing the fuses with circuit breakers because honestly I
ind breakers to
e far more convenient then looking for fuses; plus they don't run out if
ou have an issue
hat you're trying to solve that results in the breaker popping all the
ime. The start cap
uestion is asked because it may or may not be part of the whole problem
ith the motor
uses.
As my second question, I'd like to know what everyone suggests regarding
leaning and
ubricating the machine. As a joke someone suggested "Why not just dunk it
n a bath of
ylene, toluene, or both for a while?" Now, I know that will absolutely and
ompletely remove
ll the grease in the teletype... however, I also know that that will also
ompletely destroy all
he plastic and rubber parts of the teletype too -- which is probably not a
ood thing. (Though
hat would probably work wonders on a 28 or 35; which are almost completely
etal, aren't they?)
I've heard good things of people using Marvel Mystery Oil on typewriters (I
aw it used on an IBM
electric and it's apparently exceptionally good), has one here used it on
heir teleprinter to any
ood advantage?
Also, as a third question, does any one know where one can get Molex
onnectors that fit the
onnectors within the teletype? And also, how do the punch and reader
nterface with the teletype
n an ASR-33? I'm asking because I've had the idea of creating a "sort of"
SR-33 out of the KSR-33
y using a spare PC, which probably won't be feasible, as I'm thinking the
eader/punch connected
o the KSR-33 mechanisms via mechanical means and not electrically.

ow, sorry again for a very long and rambling e-mail. I'm very thankful for
ll help and suggestions. I
hould be able to do some work on them KSR-33 when I get some spare
ime/fuses. Also, if any one
ants to, you can call me Chris.

heers everyone!
