Is there a non destructive way to remove 3 piece crank without a puller?

[retrobiker273891]

It really bugs me to have to buy tools just for one job that I will probably only use a couple of times ever.

Is there not an improvised way to do it?

Looking at some videos it doesn't seem like a complex process- you are just trying to remove a tightly stuck thingy on another protruding thingy.

Can't it be done, albeit perhaps taking longer. with common workshop tools? I have no problem with the process being longer since it wouldn't be something that is done often.

The videos I have seen involve hammering or one, pointlessly, using a tool much more expensive than the puller itself. Well the only valid reason they gave in that case was if the thread had gone in the crank making a puller unusable.

I did have a go with the hammer and screwdriver method tapping on the chainrings but it didn't budge with medium hits such that I would not want to go harder at risk of damaging the rings.

A crank extractor is a marvellous thingy that has great value, even if you use it only once. If only for the satisfaction of doing something right.

This.

Any other method you'll likely ruin the taper due to uneven removal from the spindle. It's a small price to pay for something that just works.

Ok, I have to get a freewheel one too I guess so I shall buy that too.

Yes, if you have to replace your freewheel.

They are only around £5 to buy.

You can ride up and down the street with the crank bolts removed, that will loosen the arms on square taper bb's

On dead ones I've used a ball joint separator. It'll cost you a tenner for a good one or a fiver for a crhacnk extractor. Your call.

Buy a tool kit. Honestly. £50 gets good quality, and you can half that for second hand or deals on the usual platforms.

`You can use a cold chisel and a hammer to remove them. Place the chisel on the rear of the crank arm close to the axle. Give it tap - and then do the opposite side. I've done that when I have had ones which have been threaded. It does leave marks though, but perhaps a modified version might not.

Good tools do make a massive difference though reducing the risk of damage, but also just being a joy to use.

I am getting a feeling from the replies that tools are a good idea.
