Hi all,
How do I remove this crankset without a puller? Appreciate the advice.

I gotta agree with this. Anything else will not only be difficult but the chances of damaging either the frame and/or the crankset are high. Even higher if you use a hammer :eek:

The tool is inexpensive and worth every penny.

I hear you guys - just seems like a big expense for a single use. Stripping an old bike - spray painting it and putting it back together.

Do you know what exact puller I need? Are there diff types?

Well yes - I need it for a minute. A E10 tool for a minute is E600 per hour. I see that as a 'big expense for a single use' which isn't the same as expensive.

Are there different types of tool puller? Is so, which should I get for this job. Thanks.

Undo any bolts and cycle around on it for a while. My work bike has a square taper bb and the threads are gone on the cranks. Any time I need to change the bb or tighten it, I loosen the bolts with an Allen key and by the time I've done my 9 km commute the cranks are loose and just about fallen off.

False economics! You need that tool to remove cranks. They are designed not to fall off...
The €600 per hour comment is ...can't think of s suitable word. You can't pay something for something and then apply a higher nominal cost for it.

Alternatively pay a bike shop! That will make the crank extractor spins cheap at €10....

Meh I reckon 5 minutes (max) should do it. Assuming you remember to undo the bolts first! (Which Is what I forgot to do the first time I ever tried to remove cranks...now that was an expensive mistake!)

Who's to say you'll only use the tool once? The tool suggested costs less than €4! Your alternatives are as follows. 1 bring it to a bike shop and pay multiples of the €4. Pending on the shop and their charging system you could be looking at €10-€20 for removal.

Your alternative is as follows. Lay the bike on it's side and prop the crank up with wood or something. Get a bolt that strong but small enough to sit on the bottom bracket taper without touching/blocking the crank arm. Get a rubber mallet and hit the crank arm from the back until it comes lose. Now that sounds pretty simple however. I've only ever resorted to this with older cranks that were stripped so a puller wouldn't work. This method is always carried out with the understanding that the crank is for the bin anyway and you potentially damage the frame, forks etc... in the process.

If you ask me it's insane to even consider this option when you can buy the tools anywhere for next to nothing. Cost of €4 tool -v- cost or replacement cranks and possibly frame/forks. You decide what is better value.

My advice is to do the job really slowly, thereby ensuring excellent value for the cost of the tool.

Kaisr Sose

I have another suggestion that will save loads of money and leave you with a small profit.

Assuming the nominal cost of tool excluding your time is €600, if you go to a shop and pay them say €30 to do it, you will save €570. You could then buy another bike with the money saved. Then sell the old one, giving a super normal profit on the sale as the new bike was actually free.

Thanks for the reply. I appreciate it.

In general this thread is the problem with boards - too many smart Alec comments by keyboard warriors not related to the question that was posted. I asked a question about what could be used INSTEAD of a pulling tool. I didn't know that nothing else really could be used or else it would damage the bike. I didn't know - therefore I asked.
The pulling tools I saw online were €20 - but I was unsure which pulling tool (if there indeed were different ones) because I couldn't figure out the different crank sets (I thought there was only one type). I'm new to this.
And then to be ridiculed does put people off boards. You don't know my financial situation - €10 is a lot of money for me. Particularly as I'll be buying a chain, and maybe a new sprocket and I don't know what else as I'm LEARNING about bikes (you'd think you'd find support on this forum for that kinda thing). How was I to know there wasn't a cheaper way. If the tool cost €100 would everyone be as much of a smart arse about lying for one or would someone try to figure out a cheaper way to do things. Since I imagine someone somewhere would try to figure a cheaper way then why wouldn't the same be done for a €4-€10 tool. Hence why I asked. So yes - for me €4-€10 is a lot of money. I'm sorry I don't earn as much money as you do.

So I genuinely want to thank this poster for his sensible and well received comments. But for the rest of you perhaps keep your sarcasm to yourselves, and maybe be more supportive in your posts to fellow cyclists.

(Here's where I acknowledge my smart arse €600 comments and apologise for same).

All of that bluster and not one person asked where OP was based.

OP if you mention where you're based someone local might be able to swing by and loan you a crank removal tool it will take 2 mins to get the crank off.

I have one you can use if you're local to me.

When aldi have their tool kits for sale it might be no harm picking one up they're about €30 but you'll save more than €30 with them doing your own work.

You risk doing more than €10 worth of damage, especially if you're not sure what you're doing.

You're €600 comment was a bit silly too.

People gave you an honest opinion

I guess that's my point - they gave an unwanted opinion on something I didn't ask.

My point still stands that I can't really afford it and I don't know what other costs are ahead as I learn how more about bikes. This is a cheap bike that I couldn't even sell for a tenner.

And the €600 isn't that silly. If a hospital buys an MRI machine and only uses it once - there is a lot opportunity cost. If a bike shop buys the same tool for the same price as I do and use it a million times more than I ever would then obviously it's better value to the bike shop than it is to me. In other words it's far more expensive to me to use it once. As I said above - my comment was meant in the stupid way it sounded.

Actually I asked about how to remove a crankset without a puller. Thanks for your input though. Hilarious.

Besides - the nominal cost of the tool is €4. The opportunity cost is a little different. But don't let that get in a way of smart arse comment.

If you're in Dublin, I believe the charge for using the Rothar workshop is 5 euro per hour. They're well equipped and should have what you need.

It does not change the fact that if you buy something for €10 (the price you used for your €600 comparison) that's the cost. Opportunity cost does not come into it. The cost to you is what you pay for it. You are not a business with complex accounting.

As for the MRI example:...I thought you wanted this to stay on the topic of a crank puller?

I thought your €600 was silly too (that's the word I was searching for) but I hope you can manage to get a loan of a tool. If is worth paying money on bike maintenance of the aggregate of that expenditure saves you more in transport costs.

Hi Op,

I am currently in a very similar situation to you: I snapped a crank, and then, when I was trying to take the crank off, very foolishly managed to make sh*te of the plastic cap that covers the bolt. This bunged up the threads that the puller would normally go into with little bits of plastic.

Now, I learned my lesson with the next crank, and took the little plastic cap off properly - this one took about 5 mins to take off (w/ crank puller). The one that I can't use the puller on, I have spent, so far, about 2 and half hours trying to get the crank off, with no joy yet.

So, speaking from bitter experience, I would strongly encourage you to buy the puller, it will be the best €4 you have ever spent.

Btw, if anyone has had any success removing a crank with the old hammer and flathead screwdriver method, and would like to give me any advice (or just some moral support), I am all ears.

If your not interested in saving the crank, why not cut it off with a hacksaw? Cranks are aluminium, so it should be fairly easy to do (note: ive never cut off a crank myself, but I suspect cutting it off would be easier than trying to force it off with a hammer)

As I keep saying - I have a crap bike that I want to learn on. I've now realised that I need two other tools to remove the cassette (locking nut and chain whip). And I need a chain tool to replace the chain. So the cost is getting quite high quite quickly for a crappy bike that I want to try and pull apart and put back together as cheaply as I can. Cheap means not buying anything if I can cos I can't afford it. €10 might as well be €600 to me. And since I will only be using these once (as I get the bike shop to do the maintenance on my commuting bike) then again I say - this is expensive and isn't just costing €4 like everyone keeps saying.

So unless you're gonna offer advice on how to do this without buying more tools then disengage from the thread.

If you can't or don't want to buy tools, the only option is to borrow the required tools.

Whatever you do, dont buy each tool individually.....buy a tool kit:

I will gladly help you with any tool you need...and others may too if you say where you live. For a few € you can buy a full kit and it will save you lots - it's an investment (thus an asset) - not a cost!
If you speak nonsense, well you know my opinion on that by now. It's not personal as I don't know you. But nonsense is nonsense.

I have used gas blowlamp with a small well directed jet to heat an alloy crank and it came off easy enough. The only problem is that I forgot about the plastic gear cable guides under the bottom bracket which doesn't like heat and melted slightly. I think its almost impossible to remove the crank using brute force without marking it or the bike.
The right hand crank (with the chain ring) is particularly hard to remove without the proper tool, as the chain rings get in the way and are easily warped/buckled and have to be straightened.

poor cramcycle, having to deal with cranks and tools online. they're just yanking your chain.

CramCycle

It can be done with a screwdriver and and a hammer. It will damage your cranks (although only slightly if done right) but it will also wear your BB alot quicker and there is a good chance the life and use of the BB will be reduced quite a bit. google it and it will be in a few youtube comments. It takes alot longer than youtube makes out, it is tiring, you will probably slip and hurt your hands a few times. If you value your time, it is very costly.

To the OP, if your in Dublin or Wicklow, I can lend you a crank puller. The cost of meeting up though would probably rival the cost of delivery of a new one but you are welcome to borrow one. Any method without a proper tool, will be cheaper initially, if it works, but in the long run will cost you far more if you plan to reuse the parts.

Lastly, and in the nicest way possible, your 600euro comment made no sense. It costs 10euro. It does not cost 600euro even if you used it 60 times. In fact no matter what way you look at it, it would either cost less (price per use at 60 times would reduce your model to 0.17euro) or the same (one off cost).

magicbastarder

yep, it's a weird one. you would expect the time calculation you'd do based on ROI on a tool is the time *saved* by using it.

i.e. if a job will take one hour without the tool, and five minutes with one, and costs €20, your calculation would be that buying the tool is worth €20 per hour, rather than the €240 per hour suggested.

Good man. Thanks for that.

At the risk of repeating myself - which I will - I know it doesn't cost €600. I was being facetious. I took the bait very easily on the 'expensive' comment. But my point still stands - the purchase of any tool is an outlay. I've been cycling for a few years now and never needed one. I have a 'new' crap bike that I'm happy to damage. If I buy the tool, it is a relative expense for the amount of times I'll use it particularly when compared to a proper cyclist/ shop who will use it multiple times thereby getting better value than I. I also don't know what other costs are ahead - I do now.....chain whip, nut and new chain - so a very cheap project where I want to pull things apart to learn is startling to rack up in cost. If this tool cost €200 rather €10 I'm sure there would be very ingenious ideas to keep the cost down instead of being told to go out a buy more tools.
What I was looking for was advice - which the mod kindly offered in his first paragraph.
Thanks all.

How much is a hacksaw?

Either 4 euro or 240 euro. I'm getting confused.

magicbastarder

well, that depends on how many teeth per inch there are in the blade, and how fast you saw, which will give you the teeth per second on the sawing action, which you've to convert to hours, then calculate the cost of the tool vs the time and money otherwise taken by bringing the bike to the shop, so you just give up and spray some WD40 on it and hope for the best.

Basically my point was while there is an outlay, if you use the free method, you firstly don't value your time (but neither do I and would happily potter about the long way on projects, I get enjoyment out of it and therefore it is a net bonus, you may be the same). The second is that is you use the free one, while you save the initial outlay (under 10euro, or free if you borrow), the cranks will be damaged and both the cranks and the BB will not last as long (you slightly round off the square tapers and they will self wear themselves). So while your bank a/c will look better this month, you will be replacing one or the other sooner than necessary. If you do this again, the same thing will happen again, so in the long term, you will be down multiples of the initial outlay.
