Repairing Stripped Crank Arm Pedal Threads

I fix the stripped pedal mounting threads in an aluminum crank arm. The original pedals had been seized in the cranks (probably galvanic corrosion between the steel pedal axles and the aluminum cranks). I managed to get them off, but they removed some of the threads with them. Using a Unior Pedal Tap and Thread Insert Set, I remove the original thread, widen the hole and put in new threads. I then install the inserts/bushings which will have the new pedal threads. This kit is kind of expensive. If you work on a bunch of bikes, it might be worthwhile. Otherwise, you might want to have it done at your local bike shop if they have the tools. VAR makes a similar set of taps/inserts.
For those who have asked, this is the tool set I used (Unior Pedal Tap and Thread Insert Set):

I was surprised though, to see that the cranks RJ had stripped were exactly the same cranks! It made me feel just a little better. Good to know that there's a fix too.

Bacon grease will give you a fine clean smooth tapped hole. You can spin the tap clean through at the end to avoid galling the threads or otherwise damaging the threads. This type of thread repair is stronger than the original tapped hole. I could explain why, but then....you get the idea. Great video and thanks for remembering the part about clearing the chip out of the tap.

Thanks RJ excellent demo on installing heli-coils. Recently had some seriously seized pedals on a dated mountain bike. Applied a few drops of kerosene around the thread ends and left over night. Pedals come loose the following morning. Always enjoy your clips.

@joepiol5105 4 жыл бұрын

The inserts RJ used don't appear to be Helicoils. The label on the package calls them "bushings". They appear to be solid inserts. Actual Helicoils are more like springs made from diamond-shaped wire.

@BramBiesiekierski 11 ай бұрын

Heli-coils are a spring shape insert. This type shown looks to be a solid threaded bushing insert. I would suggest a heli-coil style insert would be a stronger repair than a solid insert like these. Although I have not tried either specifically for a crank/pedal repair, (yet). The reason being, when a bolt is put under tension, the tension in the bolt is not uniform. The threads towards the head end will carry alot more of the load, than those further away. Because a heli-coil is effectively a spring, it has elastic properties. Meaning as the bolt puts load into the coil, the coil will deform, both in diameter and length, and distribute that load more evenly from the length of the bolt, into the parent material. This coupled with the larger diameter/surface area from the larger external thread means that heli-coil type of insert is usually stronger than a simple tapped hole of the same size. Especially so when put into softer materials like aluminium and brass.

@BramBiesiekierski 11 ай бұрын

Im only here because I have just pulled the threads from the crank arm on my eMTB. I plan on attempting a repair and have just ordered a heli-coil style repair kit. (Heli-coil is a trade name, but there are numerous other products that function the same.) There are many crank arm thread repair videos on you tube, and they mostly seam to use the Unior brand kit, with the solid inserts. Although I have opted to use a Re-coil brand kit. Which is an Australian company. They have a coil repair kit for 9/16-20 UNEF, both left and right.

When cutting threads on a through hole, I like to keep a brush handy and brush the chips off before backing the tap out. On a blind hole, especially when you switch to a bottoming tap to thread the full depth, re-clamp the work with the open end down so chips don't build up in the bottom of the hole.

And then you will have to buy the little insert adapter 9/16 size as well . Remember you have to specify if you need it for the left or right side because they are all different. As February 23 2022 I paid $26 for both of them on Amazon. you don't need any fancy tool for this .. just the regular ones you have at home and also you don't need that lock tight liquid .. it's just for a bicycle and not for a motorcycle

Just a side note on a choice of lubricant for cutting/ drilling/ tapping aluminium and its alloys - not oil, but isopropyl alcohol (a.k.a. rubbing alcohol) or regular denaturated alcohol (a.k.a. ethanol) is the recommended lubricant (and the former seems to be better than the latter). Also, two pieces of wood (medium-hard to hard) would do better job of hoding the crank steady in vise without leaving any marks on it. A piece of playwood, HDF/ MDF board would also do the trick. (OSB board is not recommended, as it may contain small hard debris, like grains of sand or tiny pieces of rock.) Best, BTC

I got a M9000 shifter band clamp that has decided to strip itself at less than the recommended 5Nm. Since that's also a hole all the way through like the crank in this video, this should be a useful video to see how to do it. I was going to get the part replaced since it's still under warranty but what's the point if the new part is going to be a steel bolt going into soft aluminium threads again - I think if it's got a helicoil put in and done properly, it will be stronger than it would be as standard. The question of why Shimano isn't shipping these supposedly top-tier shifter band clamps with a helicoil already in - like they do with their braze-on front derailleurs - is a mystery! Shimano XTR stuff has become cheap and flimsy compared to the old 8-Speed and 9-Speed XTR stuff of the past that was near-impossible to break. Cheers RJ The Bike Guy.

There was an Odyssey BMX stem that used a single bolt to clamp the stem and handlebar via wedges. It was an ingenious system, but it was a little annoying to get it right. In any case, the bolt threaded in to a spring thread inside one of the aluminum wedges. Why nobody else does this I have no idea, but after dealing with damaged threads on aluminum stuff I wish more manufacturers implemented the system.

As said above, reaming tools shouldn't be turned in opposite direction. Tapping tools (hand tapping) generally should be reversed periodically to break chips. This tool is both a reaming, and a hand tapping tool in one. For the amount of use your likely to see. It probably won't make any difference.

@justinhart7031 3 жыл бұрын

As I was watching I was thinking the same thing regarding clean up. Yeah, tapping fluid is better. More so though I watched as he applied lube to the pedal threads then using the same finger, you can still see oil on them, to apply the thread lock. When I apply thread lock I usually clean the threads first with degreaser then methylated spirits to ensure proper bonding, especially on what is effectively a permanent threaded insert. Regardless, this is a great video that clearly shows a technical bicycle repair and is done well.

Once you start screwing everything in, it's all gonna mix! Better to install helicoil in the crank arm first, let it dry, THEN install the pedal with some oil!

i noticed that all of my aluminum bike cranks will get their threads stripped when using a removal tool? is there a better way to remove them?

@gentjanhasani5955 8 жыл бұрын

How much cost the tools in compare to the new crank arms?

@RJTheBikeGuy 8 жыл бұрын

Depends on the crank arms. The tool is expensive but will do multiple cranks arms.

RJ, what's your take on redoing things you've already video"taped"? I see a lot of channels not redoing old stuff for what seems to be the only reason that they've already done it. But what's wrong with that? I say; keep posting videos on things like wrapping handlebars,wires, tires and all the simple stuff. There's nothing wrong with having 20 videos on wrapping handlebars on 20 different but similar bikes. Newer followers might not want to go back to watch old videos and imho the more the merrier. It would probably be sort of automatic marketing of your channel as well. Whats your take on it? Anyways great channel!

+Dennis Mortensen I will sometimes do new videos on thinks I have already done. With a newer camera, tripod, lighting etc, I can maybe make a better video. Sometimes I might do stuff slightly differently. I wrap a lot of handlebars. I am sure not going to video it everytime I do it. I try to come up with new things that I haven't do before. Or if someone else has a video of something, I may shoot my own, because mine won't be the same. Different people approach things in different ways.

A little off topic: I'm trying to remove pedals from a 1973-ish Raleigh Competition that has TA Specialties cranks. The pedals are supposed to be Raleigh 501, but the only mark I can find is, "Made in France." The drive side pedal was easy to loosen, but after unscrewing a few turns, starts to bind up again. I didn't want to force things and am looking for info. It doesn't feel cross threaded. Any ideas? I wish I could put my old Look or Shimano clipless pedals on this crank, but I assume it has French threads... Thank you for your excellent videos.

Make sure you are turning them the correct way. kzfaq.info/get/bejne/is-RaNxq0My6m2Q.html

@@RJTheBikeGuy I swap pedals around on bikes frequently, so I'm confident I've got the direction right. There's something odd about this one. Are there any pedals that you don't just simply unscrew? Some sort of other locking? I've never seen such a thing. If not, then I just need to wrench it off and hope it doesn't chase a new set of messed up threads.

would this work on carbon cranks with aluminum inserts?

NO! But your bike shop can probably replace the insert.

@vidjagameenjoyer 8 жыл бұрын

+Trippin Josh It is likely rounded instead of tapered so you will have to replace it. That happens when you ride on a loose crank.

@Mrscrapiron5 6 жыл бұрын

Don't bother trying to fix it. This happened to one of my wife's bikes and I tried a dozen fixes. Just buy a new crank. It's the only way.
