Could someone tell me how to remove a 1980'S Shimano 105 Crankset?

The crank arms have a plastic dust cap over the crank bolt, I thought they just popped off but it looks like they are threaded on?

They have two little holes in both of them, do I need a special tool to remove the caps? Or am I missing something? Thanks.

just unscrew them.
spoke ends, pin spanner, biro ends, thin screwdrivers....
maybe a bit of WD40 in there first.

I had to do this exact thing last night. I used two skewers and twisted them round together. They came off quite easily.

Assuming none of the above works, this is the exact Shimano Tool you need....Shimano TL-FC21

They are normally available on Ebay. I got one because my Arabesque Crank Dustcaps were exceptionally tight. Even with this tool quite a bit of force was required. The other end of the tool is used to hold the Chainring Lock nuts while tightening/loosening.

Thanks for all the replies everyone, ended up using the two nails in a piece of wood technique! Worked fine, But I'm going to get hold of one of those tools anyway.

I broke the first dust cap trying to take it off with a screwdriver, does anybody know of anywhere to get a replacement?

Thanks again.

So that's what the wide side of the tool is for, always wondered that.
Many copies of that are available as well for not a lot.
