Bent / Broken / Seized Cotter Pin Removal - Vintage Bike Restoration

- In this video I tackle the seized cotter pins that were stopping me progressing with one of my bikes.
My usual method for cotter pin removal:
- Clamp bike securely in a maintenance stand
- Fit a piece of wood (with a hole for the cotter pin to fit in) securely under the crank arm.
- Loosen nut slightly
- Use a large hammer and heavy chisel / punch to knock the pin out.
Unfortunately that didn't work this time and the pin decided to bend. Once it does bend it is very hard to get out with force alone. The best was I've found to tackle them is to drill them out. Good quality bits are a must.

Superb Video. I’ve got one stuck and bent without a nut. That’s my weekend job with the help of your video. Back in the day you used to have to file these in using engineers blue to get the taper right. The new replacement ones seem a bit Mickey Mouse but time will tell. Thanks !
Yeah some need a bit of filing still. I need to get around to tackling a couple of bikes with cotter pins again.
I love your channel. I've watched half dozen of your videos today since I came across them. I can tell you really love these old bikes and the challenge of restoring them, as I do.
Thanks Bullwhip. Appreciate it. I do and I love getting my hands dirty.
Old video I know, but this is a big help. Might have to do this tomorrow. I bought an old Raleigh rsw. First time messing around with an old bike so you channel is so helpful.
As I've discovered, if you end up using a lot of cotter pins a cotter pin press is worth it's weight in gold!
@@MonkeyShred Yeah might need to get one, I had to drill out the one side. Just bought the tool to remove the old bottom brackets. The right tools make it so much easier.
Thanks for mentioning about the axle being made out of hardened steel. Thanks for the video!
Thanks friend to your video. I am also facing these days remove the cotter pin the same position. I also decided to use drilll and getout it like.you...Because I never done it before and confuce me how to do it correctly.
Now I can do it like you..thanks once again I am from Srilanka. We are facing many difficulties to use enough fuel in thease days
Awesome... i want to see your workbench setup for how you have your frame mounted... any videos that show that setup? Thanks!
Awesome video man
Hi just wondering if you used a cordless drill and what brand bits? I'm having trouble with mine! Left side off but drive side stuck!
I think it was cordless. Makita 18V jobby. Drill bits would have been DeWalt Cobalt bits.
argh im in the same boat same broken drill bit as well
Did that damage either the crank or the axle? I am slowly drilling through a cotter pin and am trying to avoid damaging either axle or crank (it's a very pretty crank)
It won't damage the axle, or it's unlikely to. Hardened steel. The crank on the other hand could get damaged if you drill off center.
Question ... once the cotter pin is out is that the end of it and the crankset? For example, it is time to just buy a new/more modern crankset at this time? I'm trying to figure out if there is any point in removing it all if any bike I am working on is still in good functional order. Thanks in advance all.
Nah you can still use the crankset if you’ve drilled / cut without damaging it too much. Just get new cotter pins 😌
Loved the video, thanks. Just an FYI, I don't think the background music is adding anything.
Thanks. Noted!
I wish it was easier to take off I must say.
You could have just get out the left cotter than remove the axle with crank and ball cup on it with just rotating the right cup. Chainring and cranks are garbage anyways.
You could.... but the damaged cotter pin would still be in there!
@@MonkeyShred Getting the cotter out is much easier in outside you know.
first of all why everybody in these videos removes cotter pin off a cog right side arm?? its totally pointless going through such effort, time wasting, and then risking breaking the connection later while riding. To remove the bottom bracket with the bearings the left arm needs to be removed, not the right one with a cog.
