Can someone put up a link for a crank removal tool for redline and peregrine 3 piece cranks.

Been having a look on ebay but some don't say what cranks they remove!  :-\

Thanks in advance  :daumenhoch:

You should not need a tool to remove these cranks, if you undo the pinch bolt , this should loosen the cranks grip on the spindle allowing them to be removed without a great deal of force, hope that makes sense

I've never removed a 3 piece before and not tried it on mine yet.

Once I removed the arms, I thought I needed one of these tools to remove shaft bit inside bottom bracket  :-\.

Also how do you remove bearings, is it the same one as you remove one piece bearing cups.

The crank extractor is only for cranks that use a square taper (or similar) axle and have no pinch bolt. Bit of wood and mallet hammer also used to tap out bearing cups and the bearings themselves from the cups.
Post a picture up if you're unsure :daumenhoch:

Thanks for advice chaps I'll have to get frame out and have a look.

Yes I dont think the cranks were the pinch type, so would the tool below work?

http://www.ebay.co.uk/itm/300774839971'ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649

I'll post some pics if I get stuck.

Heres a pic chaps.

1) I've removed the nut and washer off the crank arm.

2) How do I remove the crank arms (as you can see its not the bolt type on arms, like a spline inside)?  :-\ Is it just a hammer, a block of wood against the arm and tap it off?  :-\

3) Then how do I remove the bottom bracket?  :-\

I know it may seem easy questions, but I've never dealt with 3 piece cranks before, as I only ever used 1 piece.  :-[

Is there a thread inside the end of the arm for a puller tool? If not then one of these should work.

Use the socket set extension like Betty said. Failing that fella, you can have a lend of my Profile removal tool if you like, although as it's near Chrimbo the post prolly won't get it to you before the 25th :)

Quick edit - I'm off to the posties tomorrow, so if you want to borrow one of my Profiles tools, pm me your addy and I'll send it tomorrow.

Thanks for the offer, seems a bit silly posting if I can get one cheap just need to know what one.

Happy to buy a second hand one off you, if you have 2. Send me a pm with PP details.

Don't really understand how the socket set extension works.

No worries - don't really want to flog one as it's good to have spares (having broken two wellying cranks out....no cranks were harmed though :) )

The socket extension - take the female (sticky-inny bit) end, making sure it's not larger than the crank spindle, pop that end onto the top of the crank spindle and hammer the poop out of the male (sticky-outy) end. Job done.

Thanks mate I think I know what you mean now.

Do you know of any place that stock them in UK?

You can make your own tool for pulling arms on or off. All you need is a longer bolt and a bunch of penny washers taped together.

To get your cranks apart right now, put the bolt back in the arm, but leave it a turn or two loose. give the head of the bolt a whack with a hammer - you'll see things start to move. Loosen the bolt a little more and give it another whack. Assuming it's all moving now, take the bolt out before you do any damage to the threads and as others have said, use the extension bar from a socket set (or any other decent drift) and continue knocking the axle through. Eventually a crank arm will fall off, you can then knock the axle and other arm out of the bike completely. Three piece cranks are supremely simple, the axle just sits within the bearing and can be tapped in and out easily. The whole thing is clamped in position and held tight by the crank arms.

Be sure to reassemble with a good amount of copper grease on all mating surfaces.

Just realised I've got these in me photobucket, might help for a spot of reference.

Profiles assembled how they'd be on a bike:
