What is the name of this tool?

Unfortunately I only know the german name ('Klauenabzieher') which does not help much when trying to buy it in the UK,
it is used to pull off cogs from large machines or to pull off a crank with a mashed thread:

"gear puller"

or "Jeff"

bearing puller

excellent, thanks. would you recommend a 2- or a 3-arm puller for a stuck nondriveside crank?

hmmm, I could use one of those...

This one is interesting as it allows you to tighten the legs like a clamp:

(ebay, 16 GBP)

It's for extracting bearings from sea-side arcade machines.

This one's looking good too, but no clue if the size is right,
might be a miniature tool (Fastrax FAST641):

3 arm puller might be better than 2, tbh though they are a bit shit for anything thats not round. A big hammer, and a blow torch work quite well normally

it's my nondrive crank that is f*cked, so should work well I guess

Assuming you don't want the crank anymore, just whiz through it with a small angle-grinder than can be had for £10. Takes about 30 seconds.

has anyone said max crowe yet?

Actually I'd like to go on using it. If I find a nice gear puller I actually save the money for a new crank.

Ah. So when you say it's f*ed, you mean not actually f*ed then?

Well that thread isn't really important in everyday riding, isn't it?

Do you mean you've stripped the thread, or you've not got a crank extractor?

Sure I do have a crank extractor, but the previous owner mashed the thread

Extract and tap a new thread - job done good as new.

Borrow one off some one on here.

If you are near South East I have one at work.

i have one, west london

Thanks, that's very kind of you guys, but I think I will buy one anyway for future crank removals.

in french "tire-griffe" lol

alright, managed to get off the drive side and keeping the thread intact. but I know now why the previous owner mashed the other thread. this was the hardest crank I have ever removed in my life. it only came off after 3 days soaking in wd40, then heating with a heat gun, hammering with a wooden hammer from the underside and then applying brute force to the crank extractor (and then repeat the last three steps 3 times).

goddammit that was a beast... but it's off now, and I again, I can really recommend wooden hammers for that job, I think they are more suitable than the hard rubber ones as the weight is lower.
