Wobbling Crank! Help !

[chris4stars]

big post with diagrams

again..it makes no sence?! not sure what you were trying to 'bring to the table' other than a peadofile joke, some random claim about an allen key and a validation vote for yourself

at a guess, you weigh at least 50kg? so hanging of this pole would subject the allen key end of the pole to atleast 2 tons of shearing force....as well as the obvious forces on the pole...

id have said +1 for effort, but anyone who does a 'good deed' and then tells the person about how much work it involved....to me just negates the whole point of trying to help anyway. matt is still to post pics for the experienced members to try and diagnose the problem as so much has been speculation due to matts very limited descriptions.

Ok, i consider myself told, and the the allen key bit was agreeing to saying give it welly, i didnt actually hang of it any genius could see that would shear it, i used the leverage, and guessed the amount of pressure, and hey presto it worked, just said that. But obviously i can see i didn't help so in that i have said sorry for it not working. I can see it, as did 'multi tasking male' maybe matt will, maybe he wont, but untill he comments we wont know, so we will have to wait, and what with the validation thing, a cheap hack at me trying to help someone else, just because you dont see it dont mean no one else will. and for the record 62kg

Hi, just reading through, and i, like everyone else had the same problem, but, if you have the cranks i had, then this should help

|-----|-------- <-- bolt end of crank, if you can imagine the square taper being perpindicular to the shaft of the crank (Taper is the wierd square

| [-] | -------- <-- thing, middle left, incase you can't understand the diagram) this type, in my experience, is about as useful as a peado

|-----|-------- <-- trying to thread a needle in a nursery, right now if you can imagine it being 25 degrees turned like this

````````/

``````` /

`````` / ``````/``<-- I know not exactly 25 degrees but it gives you an idea, as oppossed to the above it is not perpindicular and i find this works alot

````` / ``````/ ``<-- better, i have been riding this design for the best part of 7 months and it has not failed me yet, i havent ugraded because mainly

`````/ ` [-]``/``` <-- i cant save up for love nor money, ha ironic, sorry, anyway this works well. sorry for the random commers it wouldn't fit properly

```````````/`````<-- on the page and would not look like anything i wanted it to

``````````/

And i really hope this works well for you guys cus' if you cant understand it then its been a massive waste of my time, bout 3 hours, and i accidentally deleted the first one i did, very annoying, so if it helps, much appriciated, again very very very apolagetic of the diagram i just hope it can make as much sense to you as it does me? and the bloke who said give it welly, THAT IS VERY GOOD, i got a mate to hold my bike, and got a 4 metre'ish scafolding pole, attatched it to the allen key on he end of the bolt and had some fun hanging off it, was PRO!

EDIT: the first one is crap, the second works!

hi mate , it may be my screen but it makes no sense.

maybe in words will help

thanks

thats initially what i thought about hanging off it...but it didnt really come across as a joke in your reply did it?!

you mentioned it could be to do with resolution of the screen...could be a suggestion to let people know what you use, and perhaps help people see your 3 hours of hard labour

as for the topic itself...for somthing as important as cranks, unless the problem has arisen from an initial incorrect setup or a known manufacture problem with that particular item, id not bother with any sort of fix...repeated tightening of a screw thread beyond its recommended torque is surely not a good idea either...the recommendations are there for a reason id think. with the sorts of riding trials involves and the potential for injury if a crank all of a sudden gives way, i just dont think its worth the risk.

never said 'hard labour' just 3 hours, and i aint exactly a computer geek, so i dont know bout res. just a thought, its internet explorer 9 thats what i use, maybe you need to be physically shown how the diagram is describing it, instead of a description by the side, i'm not trying to get into an argument, but i didnt say repeated tightening i just said once i understand the point you have on it, but i just said FT one time and it all good now.
