We have a selectric 2 in for a motor belt job, original belt failed after 40 years, go figure......here is the procedure for that. Same procedure works on selectric 1 , 2's & 3's. This is our first attempt at filming this & we will probably do another in the near future hoping for a better end result. This is a complicated repair since it usually involves re-timing of the operations shafts. Only takes about 50 times before you can do them really proficiently. Machine got a general clean & service afterwards.
Fixed all kinds of IBM field equipment in my territory in Iowa in the 70's. When ever I replaced a drive belt I always put a second belt in so that if the belt breaks I can replace it quickly by just finessing the second belt around the gear and done. I would just let the second belt hang loose around the shaft. Never had a problem doing so and this becomes a five minute repair.
If I see an IBM with a second belt sitting there ready to go, I will know that this might have been one you had your hands on back in the day & thank you in the process !
Seriously, thanks for this. I'm a writer and have wanted one for years. Got one for a BUCK at a garage sale, took the lid off, sure 'nuff, belts broken. So appreciate your videos.
Nicely done.... That was my first job at IBM. I noticed you have IBM issued tools too, specifically the nut driver. :)
Nice. By the way, one trick I use is to half-cycle an M, and the rotate and tilt latches let go, making it much easier.
i worked on selectric's for 22 years, took ibm training in atlanta ga. back in the early 80's still fix a few every now and then too !!!
Well your defiantly in an limited elite group of tech's
started a courier company 8 years ago, i got tired of working 7 days a week, went back to my old job this week working on office equipment, not had a typewriter to fix yet, it feels good to be back doing repairs, i actually missed it , working on canon network copiers and computers mostly..
can you fix my selectric please?
@@phoenixtypewriter2136 There's not a lot of you guys around. I need to show my dad this vid and specifically this comment you made. Even though the comment / compliment was to someone else.....he's definitely one of yall and it will bring a smile to his face. He just turned 76 years old in March.
@@kidcreator2719 Yes bring it on by to the shop . . . .
Now is the time for all good men to come to the aid of their country.
This is the phrase my dad has always typed when done with a repair.
I assume you were typing the same phrase.
What. a trip!👍👍
It's a phrase I've used also except it misses a few characters - b, j, k, p, q, v, x, z. For a full keyboard / character test "the quick brown fox...." wins out :-)
Wow, I never thought I’d see someone replace the belt.
Just found one of these in the company trash bin, thanks for posting this so i I can fix it !
Thanks for the nostalgic return to my early career at IBM. Spent 15 years there, starting out in the Office Products Division. I loved working on these mechanical marvels. They were simply the finest typewriter made, till they came out with the first generation Electronic Selectrics. those were horrible machines...
Are you talking about the wheelwriters? What's so bad about those?
The Wheelwriters were an answer to the Electronic Selectrics, they were the last generation of typewriters produced by IBM/Lexmark. The Wheelwriters used a daisy print disk, while the Electronic Selectrics used the same golf ball printheads that the Selectric III's used. At the time the Wheelwriters were introduced, IBM also pioneered some thermal printing technology, that was utilized in the Quietwriter...
@5:45 a small assembly with spring hook is removed. I do not see where in the video it is reattached. Nevermind... saw a comment further down where you acknowledged it was not reattached in the video. Thanks
You didn't put the spring and clip back on the back of that long screw that held the bracket, at least in the video.
You're right, I'm sure I put that back on afterwards. That piece is to keep operational shaft from backing up, it's also a good way to eyeball one of the time procedures. That's one of only a few parts you can take off an IBM Selectric & unit will still work 100%.
I feel like open heart surgery is easier than a belt replacement on one of these bad boys! Fortunately I won’t kill anyone if I screw up. Wish me luck!
I bought a Selectric II at an auction about 30 years ago to use in my office. Plugged it in and did not turn on so it sat in my basement forgotten for all these years. I recently rediscovered it and got it back working thanks to your videos!
Curious tho, could you clean and mark the gear orientation with say a sharpie so a guy would not have to fiddle with the timing after reassembly?
Thanks again for the videos!
Feel free to mark your gears before disassembly, I used to, but they sometimes would not line back up
That was 40 years ago, now going thru the timing process is easy for me
Would anyone in their right mind think they could reassemble all the parts you removed? Personally, I would rather hitchhike to your front door with that machine on my back, than try what you made look so easy. Regards,
i had an Olivetti electric at one time i got for free. the only problem it had was the main bearing in the motor was egg-shaped. 75 bucks to fix it. the first time i hit the return it returned all right but didn't go anywhere else. found the screw they forgot to tighten. loaned it to a friend's mom and never got it back.
I am grateful and lucky you post these videos. I've said below other videos from you that I was training at the plant in Lexington, KY in 1966 but life took me away from IBM only a few months at my first post. But, now, I want to be able to work on Selectrics again and you are awakening the brain cells. Thank you. Where do you get the belt? It looks new. Is my future spent on eBay trying to find parts?
I was there in '66. They didn't teach us how to take the covers off. My first call was on the old one without latches. :) I retired as a senior tech (what ever) and OJT instructor on most stuff after 30 years! 3 IBM Means Service Awards. Many war stories :)
I was an IBM Customer Engineer. Rather than resting the weight of the typewriter on a screwdriver to hold it down, a method that could cause damage, the proper method is to pull the bail down and then insert a thin shaft thru the lower screw hole of the side bearing to hold it down. A good thin shaft is a Bristo wrench.
Later in my career I worked side by side (business partner) with an ex-IBM selectric instructor, I would drive him nuts with my non-IBM ways
We were a good complement to each other though, lots of times he got frustrated with a job, tossed it on my bench
Only a couple times I remember having him save me from frustration. I'm Gonna try your rod thru the screw hole trick
Broken belt and broken main hub were problems I always passed on and sold customers a replacement instead.
I recently got a hold of a black IBM Selectric II correcting. It came from a Humvee plant and was put in service in '77. It even has a AMC property logo attached to it. A neat collectors item I must admit. But upon powering it up I learned it had a burnt belt. It seems something is binded, and the gear shaft doesn't move well. Then again this whole thing is going to need degreasing. I thought about just spraying it down with wd40. Expensive way to go but I don't want to use water on the assembly. But the grease is just plain old. It's not lubing anything. Anyway thank you for a video on this topic. I heard this would be hard.
Thank you very much for such clear step by step!
Very informative, a lot of work for a drive belt; however, got to do what needs to be done. :)
Hi Duane,
Thank you for the excellent videos!
I finally freed up my recently-acquired 'stuck' SELECTRIC II, and once it was operating, the ball/ ribbon carrier made one complete circuit ( traveling left to right and returned) and then the drive belt lost a few cogs. it sounded so 'sweet' during that cycle that I have to fix it. I wish that I lived in or near Phoenix , as I would just bring it into your shop for repair & service. I am a bit concerned about the quality of some of the replacement drive belts that are available. Have you experienced any brands that should be avoided?
I will check out the condition of the center hub when I go to install the new drive belt. If it is bad, I am considering 'biting the bullet' and buying the aluminum center hub pulley from the dealer on eBay. The typewriter was given to me, and so far my only expense has been to invest in an IBM SELECTRIC hand cycle crank tool.
Didn't know there was multiple brands of IBM motor belts, I've gotten my aftermarket belts from the same place for 30+ years
Going to use this to help replace the belt in my machine, thanks for showing how! How much adjusting would be required after doing this (other than what you showed in the video)?
I would suggest a new cycle clutch spring after cleaning the old shaft clamps plus a new motor clutch, as they wore out on a regular basis, also the mylar shim wore like god knows what, resulting in the flutter sound while turned on.
Very nice video! How can i reach for a question on a problem with a selectric of mine? Thanks!
do you have any videos on smith corona coronet auto 10? i found one today and it needs cleaning and inspecting. and probably a new ribbon.
Great quality video! Good to see the profession continues. Any techies know if RemingtonRand 101 Golfball can use IBM Selectric II motor, clutch, belt?
I just acquired a SR101, low mileage near mint machine, but it's hermetically sealed & stored at the moment. I know the belt is the same, centrifugal clutch looks different but I believe is interchangeable but might need the matching IBM pulley. Motors are same but the mounts might have to be changed with each motor. If I remember the SR101 had a heavy duty retainer clip compared to the small thin IBM retainer, I used some of those HD retainers on some IBM's .
Whats yr general opinion of golfball typewriters in a nutshell? Very curious.
IBM Selectric could live on for a long time, now at the 30 - 40 year mark durability has proven itself. Looks like the center hub is biggest issue & sticky-ness from old oils. Still a great go-to typewriter that is right at home doing "Odd" jobs like filling in forms, blanks, labels, shipping stuff, 2 part invoices, envelopes etc etc. Selectric is user friendly, easy to set margins, roll paper in & thru with 2 platen knobs & a variable, nice clear card guide/holder to line things up easy, cheap ribbons & nostalgia to boot !!
Yes, nostalgia and aesthetics. I'm sure I remember seeing a Selectric at my primary (elementary) school when I was 8. And more recently, the Selectric features heavily in the plot of the Fargo TV Series.
my carriage is frozen on the left side, the motor runs fine. Also I can no longer get my 1/2 spacer to work. Can you let me know what you think I need to do to get it running again.Thanks
Multiple things could be the problem, does it type? does ball strike paper? does backspace work? does shift turn ball? was it working recently? what happens when you press tab? I haven't seen anyone use 1/2 spacer in decades, a lot of selectrics don't even have a 1/2 space lever, must just be disconnected. my estimates are free while you wait & watch (5 minutes). basic repairs start at $48.00.
I have this same model of typewriter but my issue is if I hit any of the letter keys it repeats that same letter over and over and over super fast and won't stop until I pull the plug
Common, the oil in these are 40 years old and have turned to molasses, all sticky parts need to be flush completely, re-lubed
This is surely your repeating issue, th-cam.com/video/cHUYt-8vl94/w-d-xo.html
What is the goal of the electric motor? Can it be used without electricity?
Induction electric motor runs the typewriter, without it machine is useless
Motor turns the operational shafts at a precise RPM, everything is triggered from that.
All the cam's, clutches, drive train Etc. You can turn operational shafts with a hand cycle tool, but only 1/20 speed
@@phoenixtypewriter2136 Is it possible to replace the electric motor with a torsion spring motor where the potential energy in the spring is stored and then released in the form of movement, provided that the motor is well manufactured?
That would need a large spring to hold enough energy to turn the operational shaft to speed and maintain it.
Hi. Nice to meet you, I'm repairing vintage typewriter in Korea. Ibm selectric iiitypewriter of parts I need the belt. Do you have a place to purchase a belt?
안병조 www.typewriters.com/selectric-parts.html
So I just replaced my belt, and after using the screwdriver-under-the-selector trick you described, my whole selector is stuck in the down position. In short, the keyboard dosent work. Do you know how to remedy this?
Well without seeing it in person it's hard to tell what to do, but I have seen the selection latches get on the wrong side impeding selector from moving, just a matter of looking and checking all those plus or any other unforeseen binds.
Nevermind, I missed a linkage that got misaligned when I put it back together. You were correct about the latches
Hi, I was wondering, how much do you charge to repair and to do a general service?
My base price for service, repairs, cleaning is $ 48.00
👍👍
Not for the faint of heart….
If you can afford the $48 or so, let a guy with experience do it. You should be careful not to nick the tilt and rotate ‘tapes’ (actually steel bands), for these will break easily when damaged.
not replacing cycle clutch with belt is a crime sir.
Customers IBM, they are always given this option & others, they did the minimal.
If this was a machine that was getting refurbished for re-sell, Yes I would have changed the c/c.
I believe the clutch was replaced when we did the hub job on this machines years ago
That argument has been going on for over 40 years! :-)
At least clean it and grease the Cycle clutch, also check the basic tilt and rotate adjustments and timing. There is a stud on the side of the carrier you can use to line up the print shaft groove with. The amount of time it takes to change the clutch when the cycle shaft is out is minimal.
I still have my 1/4" - 5/16" nut driver with slide handle! So does my dad!
This brings back some memories from when I worked for my dad about 30 years ago.
He still works on Selectrics....all typewriters really.

Probably the cowboy way of doing this, not the correct way. The cycle clutch pulley should have been replaced did anyone see the huge crack in it, the gears should have been adjusted for the correct backlash and then re-timed, the belt tension should have been adjusted. You can download the adjustment guide for free from the internet, why not follow the IBM manual and do it correctly.
I like that description, Cowboy way ! Trained by IBM personal, my Business partner was an IBM trainer, so I know the IBM way. Never said this was the IBM way, in fact most my videos doing serious repairs I state it's not the IBM way, it's my way (Cowboy). BTW the Hub Pulley has been replaced with reinforced metal ring years ago & Robert Fallin, cycle clutch was reversed/replaced then too, mistake was not replacing belt then. Being this is a Noncorrecting, I'm sure that customer was under budget limitations. Cowboy Up !
Problem is...if you do it the right way, stripping the shaft, replacing the cycle clutch pulley, loosening all the pulleys, then doing all the adjustments, the average joe watching this video won't be able to follow it, without the right tools, hooverometer, etc..etc. Don't get me wrong, its great to see them still working, and great to see you passing on knowledge that people can follow. I was an IBM (trained) tech and worked on them for over 10 years until they were replaced with the electronics. Always amazed me how complex they were with, interlocks on almost everything.
Some very valid points you make. Got to be a very small amount of amateurs who would try this even the Cowboy way. Lots of people think it's like changing a vacuum belt ! And yes the mechanical selectric's are so different from any other standard typewriter that it does require a different skill set.
