removing a crankset without a proper crank puller

[BigonaBianchi]

I dont have the right tool....apparently....cough....
anyway.....i removed th ebolts on the crankset to be faced with a square looking recess and a crank stuck like glue. I read online that riding with the bolts out may shift them but it didnt....I can order a crank puller online (which one??) will this work or I can find another way and get these off today while i have time and it's raining.....is there any way I can shift the cranks without a puller? Would a hammer wrapped in a rag shift them?

It's a fsa crank....think it's old oldstyle as very big and heavy...

any serious and lunatic suggestions welcome as usual Ta,

Get the puller.

I've hit cranks from behind with a chisel before but the bikes were old knackers. The tool will save your bike and fingers.

The crank puller is not that expensive, most cycle shops sell them but they will sometimes loosen by riding round the block with the bolt in, nut on but loosely as if it does come free with no bolt/nut there it will drop off.

Get the puller.

Most of the other methods could damage either the cranks or the bottom bracket. It's well worth spending £15 on the correct tool that can then be used again in the future, rather than risk cocking it up and having to spend well over £15 on replacement parts (and the correct tool after all).

Don't try it without a puller - it will end in tears !

Just a tip, avoid that Park one you linked to and get the Park one that doesn't have a handle - you then use a big spanner - gives more leverage to get the crank off.

Advice taken...handleless park puller invested in ...

you've got perfect justification to buy a tool, a cheap one at that, and you're trying to not buy it.

normally the issue is contriving a tenuous justification for some shiny item you don't really need.

joking aside, just buy the proper tool - they are cheap and will do the job

I've got a couple of copper wedges I've used when the cranks are so 'welded' on, the puller has stripped the threads.

I bought the tool at lbs and removed the crankset ok. Now I am looking at a square end spindle, and can't get the inner casing of the bottom bracket ( I guess these are what peeps call cups??) Out. The inner ring of these cups has a circle of what look like small castle battlements . I guess these are wherei need another tool??? The veloce crankset does not fit over the square spindle as it has a hexagonal recess. The guy at Merlin bikes said the veloce crank would fit a square end spindle...erm..they don't as far as I can tell.
Soooo.....

What other tool do I need?
I am assuming I need a new bottom bracket now and nit just the veloce power torque cups I have in my hand?

I'm trying to upload a picture but failing on my phone..sorry...

I can visualise the tool would look like a cylinder with matching ' battlements' to slot in to this bottom bracket...which I think came with the fsa tempo crankset I have just removed.
This must be the bottom bracket removal tool I don't have right?
...inserts vulgar profanity here.

You need an olde fanglede bike spanner, that is flat with a concave edge and a little bibble on the end. The bibble fits into the battlements on the lock ring and the concave edge fits around it and it unscrews. Then depending on the age of the bike you can undo the removable cup (old bike) or the whole enclosed BB (new bike). If it's an old bike and you take out the axle and bearings and want to put a new modern BB in, you'll have to remove the fixed cup (non-drive-side). THat can be a bugger of a job, but Sheldon has instructions for a magic home made tool.

Ye Olde Bike Spannere

hmmm..that one looks like something I saw in braveheart during the disembowlment scene ...eek lol!

I am going through this 'pain' so I can learn really...then once I have a full set of bike shop tools that fit I will be able to do this stuff without LBS labour costs....which I am realizing arn't unreasonable given the pain...but my guess is it's all about the right tool for the job......question is am I the right tool? Lol!

Back to LBS on the Morrow to add to my tool set collection....I'll get there!

You can tap the cups round with a screwdriver and a hammer, though the proper tool is the way to go. The one in the picture above will do the job, but a long handled C spanner is better. Just be sure you know whether you have a British bottom bracket which has a left hand thread on the right side cup (Chainside) or an Italian one which has R/H threads on both cups.

this is pretty much what im am looking at without the tool to remove it.....i'll try the screwdriver thinng gently as i need to use this bb on an old bike re build afterwards.

 

[Smokin Joe]

Aha!

I was thinking about a different type of BB cup, as was Dogtrousers hence the picture he posted. I would not attempt to shift that one with a hammer and screwdriver, get the proper tool.
