Where can I buy a Pedal Tap In North Dallas

I messed up the threads where the pedal screws into the crank ( arm) I stopped by a bike shop and said I would need a pedal tap...but they dont carry them.....Anyone know of a place in north dallas where I might find a pedal tap to fix the threads??

Thanks

You could try the taps, the size is 9/16" X 20TPI, right hand thread for the right crank, left hand thread for the left one. You could also try starting the pedals in from the inside and seeing if you can re-form the distorted threads enough to thread them in the right way. Understand that a tap can only remove metal so if the fit is too loose due to the metal being stripped out there will be nothing to tap into. In this case the repair is to drill the hole oversize and using a special tap make new, oversize threads and then install a Helicoil threaded insert. This will make stronger threads than the original aluminum. An older bike shop or a machine shop would be places to inquire about this. It is a quick and relatively simple job but the cost of the specialized tooling (taps and insertion tool) required makes it uneconomical to do yourself.
Grease the pedal threads and start them by hand so that you do not damage the threads again; if they do not go smoothly STOP and find out why. I use Tef-Gel anti-seize paste and also stainless pedal washers to help prevent the pedals binding or galling and to ease removal.

Call around for the Park Tool set-up,should be about $35.It will cost you more than that for a HHS left hand thread tap from a machine tool place.

Or like they said above,use the pedal to chase the threads from the back with some anti-seize or grease.

I did the same thing about a year ago, enquired at the LBS about getting the crank re-threaded, no dice, enquired at a local engineering works about it, maybe helicoil? no dice. I ended up throwing the crank and bought a new one on ebay for 8.00.

ya...i have tried putting the pedal in from the back....its just not quite long enought to get the last two threads. So...I either need the tap...or the Crank puller to take it off and take it to a bike shop......Finding either the puller or the Tap locally seems to be impossible......UGH..( i can find it on the net...just want to walk in somewhere and grab it and go! )

Any decent LBS should have a crank puller for sale.

If it is the right hand crank you might be able to find a 9/16-20 bolt that is long enough to do the job, or maybe pull the axle out of an old set of pedals and use that; yes, I'm stretching here. Are there any machine shops around that you could check with?

no...its the left crank......right prolly wouldnt be such a problem......I thought these were suppose to tighten as you pedal?? came right out while pedaling.....My fault for not getting it tight enough...needed an open end wrench instead of monkey wrench.....Think monkey wrenchs cause more problems than they fix!

LBS stands for Local Bike Shop, to differentiate LBSes that mainly sell bikes from places that might sell, for example, groceries, clothes, cheap sporting goods, and BSOs (Bicycle-Shaped Objects). If an LBS doesn't sell very basic tools like crank pullers, though, they are probably not very good.

You might be able to improvise a pedal tap out of an old pedal, as dsbrantjr said above, if you can grind off some of the wide bit with the wrench flats just above the threads to give yourself more length. You are probably better off finding an LBS with a pedal tap, though; even if they don't have one for sale, some place in your area must have one for them to use.

This is on a Proform Tour de france stationary bike.......Had it two weeks and its been completely functional for about 20 minutes......Came with some loose parts in front hub.....Couldnt get covers off to tighten ( No crank puller )......then after those got tightened...the pedal fell off....( My fault )......so......anyway.....looking forward to some competitons on IFIT...

Most decent bike shops will have a set of pedal taps for use by their own mechanics but won't have extra sets for sale. See if the shop can clean up the threads using their own taps rather than asking if they have a set for sale. I hope you don't need your own taps routinely.

Ahhh.....those days are mostly gone thanks to the low-price-at-all-costs internet shopping experience. And those of us who still bother to stock such things grow very tired of hearing people say "thanks, but I can get it cheaper online"....

Unless you or your shop have a drill press, it's unlikely you will have success with a Helicoil. Very annoying to go through all that grief only to end up with a pedal that isn't exactly straight. Sounds like the pedal wasn't fully tightened during assembly.

the bike shop can order you a pair for home use,
but will not have a set to buy on Spec.waiting..
Call first and they should be there in a fortnight.

got it fixed.....Found a CP 22 crank remover.....took it off and brought it back to the bike shop.....they chased the thread and all is good....And your are correct....."I" didnt get the pedal tight......but ....i thought the whole reason to have reverse thread was to prevent it from backing out while riding.......but in the end....I didnt get it tight....

Thanks again everyone....I was able to get 30 minutes in last night with everyones help.

I know I have been out of the business for quite some time but how do you run a shop without pedal taps? I know you don't use them everyday but still for the cost of a tool that will last 20+ years why not have them.

A pedal tap is an expensive purchase for a one-off job. Surely there is a bike shop in your area that can re-tap the arm for you.

So your saying you basically had a "failure to communicate" on the part of you and the shop employees?

Sometimes if you bugger up the threads, you can make it work
by threading the pedal in to the back side of the crank, and straighten out the threads,
then screw in the pedal the proper way..

He already tried exactly that. Read post #7.
