How To Remove Stuck Crank Cotter Pin With A Vise On Vintage Bike

- I use a vise to remove a stuck wedge cotter pin from the crank of a 45 year old Raleigh bike. The pins in cottered cranks can be VERY difficult to remove. There are multiple ways to do it. The best way is to use a pin press if you have one, but most people don't. You can also hammer the pin out. In this video I use a vise to press the pin out. I also use penetrating oil to help get it loosened.

Brilliant idea! I’m restoring a 1963 Armstrong. The hammer wasn’t doing anything for me, so I gave this a shot. It took a lot of setup, since I had to remove and transport a bench vice, but it worked well. The resulting explosion of the cotter pin letting go was fantastic. Thanks!
Thanks fella. It worked a treat.
This worked perfectly for me, thanks! The only thing I would change is put the pin in the center of the vise jaws. Looks like you have a good old vise, but a cheap vise might break. I put my bike sideways balanced between 2 chairs so the pin was in the middle of the vise and after some penetrating oil and a cheater bar it came out easily.
Yeah, my vise is pretty heavy duty.
Yeeeesssss this actually worked, thanks dude
Perfect! Did the trick although with much more rudimentary tools, but the same idea. Thanks a lot
I modified your approach using a socket and an 8" C-clamp to get the pin out of an 1890's bike crank. I had not been able to drive it out with a wood block and hammer. With the C clamp tightened down just enough, I gave the clamp a whack with a hammer and the pin popped out instantly. The clamp makes a nice big target for the hammer, BTW.
I have been looking for this video for a week, I knew you had one, and will now employ your technique. I will report back with update.
Bummer that my video didn't easily show up.
THATS SO BRILLIANT. i'll be putting this to work tomorrow

As a lifelong cyclist, I am puzzled as to why it took me forty odd years to learn this secret to removing cottered pins! I've read that some cycle tool manufacturers used to make special cotter pin removing tools, an one time ("...at band camp...!"), I even saw photos of some of them ; but honestly, do they even exist??!! Get a vice----- everyman needs a vice!. Notes: penetrating oils/ heat/ tapping(ultrasound!) ----- all are unnecessary as the power of the Acme threads in a vice are supreme. Do however ensure the pin is centrally located in the jaws of the vice. Lastly : the perfect spacer washer to use over the end of the cotter will be found on the old style five speed blocks ; it's the axle spacer washer on the drive side.
This is a great resource channel for cyclists, please keep it up. 🚴🙏
Great idea....Only thing I do different is when using a hammer on any bicycle, I use brass or bronze hammer.

That was pretty smart using that socket like that, a large clamp might work too possibly, but so now are the threads ok?
I have a tuck tricycle wheel that the pin is rusted on so bad that i can't twist the pin to move but you have me a good idea with the vice & the socket so i can remove the wheel.
I'm restoring my dad's shimano aerodynamic and has also the same pin from the crank. I have a problem with the pin because it's broken and vise grip(small one) wont unscrew it. I don't have tools to do the things you did in this video. BTW your vids helped me a lot :)
Sorry for bad english.
Then get the tools or take it to a bike shop that has tools.
We dont have bike shops here in our town :( Btw thanks for replying
I was able to get cotter pins out of a 1970s Peugeot this way - thank you!
You are a genius! I'm going to try that on my bike! Thanks!!
Thanks, that's an excellent tip.
Thanks for that. I bought this bike from charity I bought these modern tools but I realised it was a vintage one 🤣.
If you don't have a spare loose vice, you can use a G clamp instead. Put the moveable foot on the socket side, the fixed foot against the pin. Do it up tight and then go and get a cup of tea, you'll find all the pieces on the floor when you get back.
That's what I did with my Raleigh Sports 3-speed in junior high school. The CLANG! at 3 AM woke the whole household; nobody else shared my exultation.

2:39 at this stage i tap the vice with a hammer a few times, and continue tightening more but without a cheater bar. This way the impact force really helps breaking the pin loose without damaging it.
thousand thanks, had an old legnano with the pin cut in an half and this the only way out of that :)
question...before I saw this video, I tried removal using a hammer and now have a mushroomed over pin. Any thoughts on how to remove a pin once mushroomed?
Yep, sometimes they just don't want to come out. Drill down through the pin to relieve pressure, and then pound it out with punch.
I had to do that in this video: Overhaul Bottom Bracket On Vintage Peugeot Bike
i have just removed the cotter pin from the opposite side of the chainring, but on the chainring side can see no sign of there being a cotter pin, any ideas?
+alex carter Nope. Never seen a cotter pin on only one side.
have you got a contact email so i can send a couple of photos please, thanks
You can post them on my facebook page.
I use this method to break chains
I just use a chain break tool.
@@RJTheBikeGuy that is if you don't have one or you lost it
Rolly? RALEIGH. RA as in RABBIT.
Not to a British
@@ashs3380 I'm British and its pronounced either way.
Ok, the problem is that I did smash the pin, now looks like a mushroom now what ?
+imagringa Replace it. You will need to get a new one.You will need to find one of the same diameter. And file it down to match the profile of the old one. Check this video around the 6:45 mark: th-cam.com/video/9Qc2wzyeXk0/w-d-xo.html
can u control your breathing on your videos
The camera was right next to my face to get the shot.
What kind of comment is this?
RJ ignore that.
