Removing old bicycle crank cotter pin after 45 years! Cheap tool & easy method, works every time!

[@shauntaylor4758]

Very satisfying, especially the suspense of waiting for the cotter pin to release.

I'm glad I'm not the only person who uses one of these for removing cotter pins. So much easier and less damaging than whacking with a hammer.

When I sent my bikes to the shop, they use a hammer.

Hi Rowan, great video as per usual. Hoping with restrictions being lifted this next few weeks to come up to Blackpool with the traveller all being well.

That's a nice tool. You can buy a new version of the same at Halfords - and a dremel to make the dimple. The only improvement I could suggest would be a dab of grease on the driver thread each time.

I was ready to grab a hammer and pound away until I saw your video. I have one of these tools, and it never occurred to me to use it for this. Thank you for the revelation. I can now remove the cranks from my Raleigh Sports 10.

[@shipsidedutyfree9981]

What do you call that tool and where can you buy it? I need one . TY

[@threespeednut3091]

Nice way to get them out, always a challenge to get them out undamaged after a few years. I tried your recommendation on an ealier video about using Tcut today, excellent results, my 82 Raleigh Hercules now really shines, the metallic bronze looks dull and uninspiring in the shade but always looked good in the sun, now it radiates colour when in the sun.

Thankyou! Much better than a hamering.

Great video. I always look forward to them.

I’d have put the nut on loose by a few mm to protect the thread from deforming under pressure

On my own bikes I decided that if I ever have to take a cotter crank off, the one that goes back on will be square taper. Not original but also not horrible.

[@JustClaude13]

I tried that but didn't understand the purpose of the dimple. As a result I bent the threaded end and broke it off when I tried to straighten it. This let me drop a 1/4" socket extension down into the resulting well and give a solid strike with a hammer that finally popped off the cotter. This wasn't a major problem, since I had already decided to install new cotters, but I wanted to emphasize the importance of the dimple. Without it, the tool won't push straight down on the pin and will destroy the threaded section.

[@unbalancedcrank]

Sounds pretty much like how I refined the design to include a dimple! Also grinding the curve flatter before drilling the dimple seems to help too.

Nice video ,very informative .

[@farouqomaro598]

Wow thanks!

[@ocelot2234]

Exactly how I do them lol 😂
