Trials Dave Posted May 14, 2006 Report Share Posted May 14, 2006 (edited) as the title says it has stripped. i have a spare pedal either left or right one which i can put in.are there any fixes for the meanwhile until i have money.i thought about maybe drilling the back of the crank arm out and then putting a nut in. so i can thread my pedal into the nut.

Jaffacakes Posted May 14, 2006 Report Share Posted May 14, 2006 If you don't mind losing your pedals your best bet would be glueing them into your cranks with alderite.I forget which side the normal thread is but you could always helicoil it if its the side with normal threads.

Davetrials Posted May 14, 2006 Report Share Posted May 14, 2006 errrm, araldite wont do a lotthe thread usually isnt long enough to get a nut on, there isnt a lot you can do bar forcing it in cross threaded and make it last a bit, pedal wont be flat though.get it helicoiled, it isnt too much, 25-30 quid Quote Link to comment Share on other sites More sharing options...

IOLO Posted May 14, 2006 Report Share Posted May 14, 2006 im presuming they are aluminium cranks, and of course a steel pedal axle.it a vert triky one for bodging,put your pedal into the crank, then drill a 2mm ish hole straight through the crank ends and the pedal alxe, and put a thin nut/bolt through the whole thing, or a split pin, or just some thick wire, and bend both ends,hmmor..get hold of a tensile pedal thread unsert and use that, by grinding some crank away, liek you said,both plans so far weaken things.. but they may get u on your bike for a week ish.bodge away !!iolo.

the_soon_to_be Posted May 14, 2006 Report Share Posted May 14, 2006 first, fix the pedal in the crank using araldite..centre punch the middle of the crank, with the arm lenght ways, so it is like...erm, cannot explain, imagine you have a hard on, and you nob is on end, centre punch where you japs is, going down itonce you have done that, going through the pedal...use a tap, maybe, 5-6mm, and tap all the way through the pedal.... should be ok for a while Quote Link to comment Share on other sites More sharing options...
craigjames Posted May 14, 2006 Report Share Posted May 14, 2006 the pedal inserts are probably the best way forward. drilling a pin through the end of the crank arm... cant imagine that lasting too long!! Quote Link to comment Share on other sites More sharing options...
the_soon_to_be Posted May 14, 2006 Report Share Posted May 14, 2006 well it won't but it will last a bitdepends how handy he is with tools, might not be able to tell a drill from his arse hole Quote Link to comment Share on other sites More sharing options...

Trials Dave Posted May 16, 2006 Author Report Share Posted May 16, 2006 is it possible to get opposite thread helicoils? Quote Link to comment Share on other sites More sharing options...
Bionic Balls Posted May 16, 2006 Report Share Posted May 16, 2006 i'm sure you probably can...but it's hard enough to find left-handed taps, let alone inserts..adam Quote Link to comment Share on other sites More sharing options...
Trials Dave Posted May 16, 2006 Author Report Share Posted May 16, 2006 i am going to get it helicoiled tomorrow. do they last long?worth the time, money and effort etc? Quote Link to comment Share on other sites More sharing options...
Simpson Posted May 17, 2006 Report Share Posted May 17, 2006 is it possible to get opposite thread helicoils?This may sound REALLY stupid but with cranks cant you put the thread round the other way??i think you can get reverse threads but doubt they will have them down the garage - i dont know anything :$ Quote Link to comment Share on other sites More sharing options...
the judge Posted May 17, 2006 Report Share Posted May 17, 2006 i am going to get it helicoiled tomorrow. do they last long?worth the time, money and effort etc?If done properly it'll be better than the original thread. I've had my 4bolt mounts done in my frame and they're sound Quote Link to comment Share on other sites More sharing options...
Tom Booth Posted May 17, 2006 Report Share Posted May 17, 2006 Will a heli-coil not just wind out thou? 'Cus theres nothign on the ther side to stop the coil "undo'in" surely it will just thread outwards? Tom Quote Link to comment Share on other sites More sharing options...
MrSuave Posted May 17, 2006 Report Share Posted May 17, 2006 find your local bearings and transmission supplier, go see them and buy an insert to suit your pedal thread diameter and pitch (little fat brass looking things with threads in one side and knurled bit otherside), youll have to drill out your existing crank thread then whack this in with a hammer, your pedal with thread in perfectly and you wont have to buy new cranks and the insert will cost about 20p. very similar to getting a tensile insert except you save a good few quid Quote Link to comment Share on other sites More sharing options...
sir trial a lot Posted May 18, 2006 Report Share Posted May 18, 2006 Daves sorted now. ULTIMATE bodge He came to mine so we drilled about half way through the crank arm with a large drill and found a nut to fit the pedal thread, next i had to grind all the sides of the nut down for it to fit the drilled hole and we pressed it in with a vice. Next we put the pedal in and tightened it up. A good job jobbed:) Im sure Dave will get pictures of my fantabulous bodge Quote Link to comment Share on other sites More sharing options...
