Thanks, Don! I think I'll try it when I screw up the courage. What the
heck, if I mess things up, the result is the same--an unusuable piece of
equipment.
But I think you forgot a very important step:
"First, pour yourself a good stiff drink..."
Cheers,
Chuck

At any rate, I've got a very nice Selectric II typewriter with a broken
drive belt. I've got a replacement, but I'm very wary about taking
screwdrivers and whatnot to the mechanical marvel.
Does anyone know how to do this who'd care to give me a step-by-step?
I'd
hate to throw the thing out--it is/was a great
machine.
I'm not sure how this is done on a "Selectric II" -- I
didn't know they made I/O's of the II.
But, on the "regular" Selectric I/O, you remove the cover
(obviously) and slide the carriage to the far right. This gives
you access to the left dust cover (be careful not to mangle the
tapes as you remove that!)
On the left side (YOUR left) of the carriage there is a
cover over the idler gear. Take it off. While you are there,
loosen the 2 screws? that hold the bracket carrying the
C1 contacts and the lower idler gear.
Take off the selection switch assembly. Don't mangle any of
the blades. Try to notice the positions of the screws that
mount it (mark them) so you can get a headstart aligning it
correctly when you reassemble. Use a piece of string/wire
or rubber bands to hold it out of the way towards the front
of the machine.
Then, take out the two screws that hold the pusher cam follower
onto the bottom of the machine.
In the guts of the machine, you have to carefully take off
the spring and pawl for the cycle clutch. Don't drop the
spring! :> Or the little horseshoe clip that holds
the pawl on its fulcrum.
Now, you disembowel the machine :>
First, take off the three screws that hold the cycle shaft
in place (on the left side of the chassis). Carefully pry
the plate from the frame of the machine. Slip the spring
off the positive latch bail (this is the follower that rides
on the positive cams).
Push/pull the positive bail down and, while holding it there,
remove the selectors from behind the bail. Now you need
patience and/or a couple of extra arms...
Push the -5 and rotate 2 links out of the way (hard to describe
what/where they are... just watch for interference and THINK
about how you can coerce these things out of the way).
While doing this, slide the shaft out the left side of the
frame. You don;t need to pull it all the way out. Just
enough to get the drive belt off the shaft. Watch for any shims
that might be there to hold the shaft aligned properly.
To reassemble, just do everything backwards! :>
This is not really a task to be tackled casually. You
really need to THINK about each step as you are doing it
so you don't bust anything. And, you want it all to fit back
together with minimal amount of tweeking required.
Avoid any of the cams that move the tapes since any little
alteration there will affect printing.
Good luck!
