Help! How do I remove this vintage Crank?
I've only ever removed cotterpinned crank and BB sets. However, here we have a Gipiemme Royal crankset and I don't know how to go about getting it off:

Also, I've been thinking of picking up a reasonably priced tool kit, will any of the tools in here help me do the above?: https://www.halfords.com/webapp/wcs/s...egoryId_242558
They're all probably pretty crappy, but I've only got a weekend to do this and there's no closer shop.
Thanks

You remove the nut with a box wrench, most often a 14 mm, and sometimes a 15 mm. Then you screw a cotterless crank puller in, while making sure you don't ruin the thread. Old cranksets like that all have a 22 mm thread, so most pullers fit. And when the crank puller is in, you turn the inside axle down.

Make sure you know what crank you have cause they DO NOT all use the same tool. Most are 22mm, TA cranks use a 23mm, and Stronglight uses 23.35mm. Using the incorrect puller will ruin the crank.

It looks like there may be a crank puller tool in that kit, but it's hard to see, or tell if it is the correct size. That crank bolt looks a little rusty, but it may just be surface oxidation. Don't forget, after you remove that bolt, there is a washer underneath it that must be removed before you thread the crank puller into the crank arm.

Biggest thing that most people miss when removing square tapered cranks for the first time is to remove the washer under the crank mounting bolt before installing the crank puller. A lot of cranks have had their threads stripped this way as that washer is very easy to miss.

And... it helps to lube the threads of the crank puller with lithium or moly grease prior to use - this decreases effort of removal and preserves the tool for further use. Good luck!

Great! thanks guys, it's off now, cleaned up and looking good. The BB is in perfect nick too, all going well so far.
I don't know what this crank puller machine is, I vary carefully used a socket wrench and that worked fine, didn't damage any threads.
