I learned a lot about right crank threads and right pedal repairs

You're the Greatest. I bought a reconditioned spin bike eight years ago (I know...I know... you live and you learn) and I immediately used it. Within two days the right hand pedal fell off. I examined the pedal threads and they were stripped and the pedal crank as well. Since that time it became a paper weight until I saw your video and right away it made sense. I checked off all the tools and materials that I would need from your video and waited a month for all of it to eventually be delivered. The Unior bushing and the pedal tap took the longest to arrive since they were out of stock domestically, they were ordered from Spain and France respectively. I reviewed your video countless times to detect any nuances that might benefit a successful repair. Aside from that I checked other taps and bushings that were sold on Amazon and the reviews were discouraging. Most of the purchasers revealed horrible results. Finally I was able to use all the tools, parts, cutting oil, thread locker, and air canister in your video to commence with my repair work. It only took five minutes from start to finish. It was successful and I couldn't be any happier. I 'm allowing the Loctite thread locker to set a couple of days.

Thank you for this. You gave me hope to revive my smart bike which has the crank threads stripped.

Thank you! Just threaded my left Chester pedal in and it went in like butter. My right went in smooth half way then I encountered resistance. Wrenched on the pedal all the way and I thought stripped out the threads. Looking at the back side of the crank I can see the threads are somehow smashed Flat completely. This kit will come in handy! Thank you.

Ah finally found the right video solution and the products I need to order. Thank you, you solved a problem nagging me for weeks!

Great video and very self explanatory! Ordering my repair kit today. Thanks for sharing.

Thanks! I thought I'd need to replace my crank. Ill comment when I'm done. 👌🏼

This is a great video. You have a pleasant on-camera demeanor. You speak clearly and the video shows precisely what to do. Great work. (Oh, I think you are the doppelganger of Sanjay Gupta.)

Thank you this was really helpful.

man i thought i needed a whole new crank set thank you!

Your video was use full thank you

Nice video! Thanks for an awesome tutorial

Thanks for this. Great video.

Great video, clear explanation!

EXACTLY WHAT I NEEDED!!! THX- I stripped my statist left bike pedal crank arm.... your a life saver☆☆☆☆☆

Really understood...quite clear...will try doing my own because your video was clear

Like many of you that have experienced this I had spent hours trying to figure out the best solution to fix this problem the bike shops were charging high prices and the unior kit itself was too expensive being from the uk I tried to source the pedal tap but was costing too much to have it shipped here. I had the threaded crank issue on my drivers (right hand) side so here’s what I did(extremely simple did not require any vices/ grips or unnecessary attachments. After waiting ages I managed to source a single unior pedal tap from *deporvillage* and a helicoil from *sjs cycles* all in all I spent £42 for these 2 items I simply laid my bike upside down used an adjustable wrench to turn the pedal tap once it was inserted in the crank and simply turned. The measurements confused me as I had no idea what size helicoil or pedal tap I would need but I believe more than likely most bikes nowadays have the measurements of 9/16 which could also be called 5/8. Make sure when purchasing that the measurements of the helicoil and unior pedal tap are the same for example my bike required a 5/8X 24 also seen as 9/16X24 I made the mistake of purchasing a pedal tap off of eBay and the size was 5/8X20 which also did not thread correctly 🤦🏽‍♂️avoid buying cheap to save money and purchase the unior tap. Also thanks to the creator of this video made this extremely easy to follow

Thank you for very informative video💯🙌

I just had a Crank Arm Thread issue a couple of days back. After some attempts finally found the solution through a Local Forge expert, who used the same rethreading tool (eventually arm thread was fine, only it needed a torsional forces with a heavy thread sleeve). Was talking about this frequently during the whole time & KZfaq comes with this today ! SCARY AI & Tech !

Helped a lot thank you very much

Beautiful video

You need to reverse the tap around every turn to get rid of any steel chips. former machinist.

Thank you, I’m going on a long journey to save my exercise bike. I thought there was something wrong with the pedal and just kept screwing in back in. Needless to say, I destroyed the crank threads and am mentally kicking myself. Your video explained a lot and at least I know where to start.

i think i may have runied my thread on my giant tcr, but after watching this im not to worried as you explained it so well to fix..

Thanks for sharing! Just have to find that union kit, have not been able to locate yet.

For the last part of the process, it works out easier if you thread the new bushing ( Helicoil ) onto the pedal first, then use the pedal as a delivery system for introducing the bushing into the crank.

Fantastic video, thank you sir !

I loved the video, so thank you for that. I understand these are special tools. Now... $178 + $11 = $189 --> Almost $200 to be able to perform this service is a little too much. Unfortunately, it looks like it would be cheaper (and easier) to order new crank arms and just replace it.

Hi I love your video and I will work on my right hand pendal which have wear out and I would be using your video to fixed. My bike is Carera Crosscity ebike Folding bike. I will send you a feed back too.

That's very handy now I don't have to buy a new crank arm all together

life saver

Can you do this on a chromoly crank arm? I have re-thread alloy before but I do know chromoly is a harder steel. ?? Any replay

Excellent video! Thank you! Stripped pedals all because the #1 bike shop rule isn't followed: "All the way on or all the way off!" Never "just snug it down and come back to it later" in bike repair. Doing this may kill you, someone you love or a customer. Your pedal may fall off, your stem may twist, your front wheel may fall off! This has happened and will happen time and time again when this rule is disregarded or forgotten. This is what employs lawyers and ruins lives. Three rules to follow when working on bikes (and stuff in general) and you'll go far (figuratively and literally!): 1) All the way on or all the way off! 2) Grease metal-metal contact. (Yes, there are exceptions. But they are few.) 3) Test ride all your work.

I bought used Dahon vybe D7 folding bike. The pedal is foldable. It wad broken today. Could it be fixed ? thanks

It looks like Unior has discontinued the kit, but added a new kit to their site with a tap handle for $300. Kinda rough for just fixing a crank set arm! The taps and tap handle are easy enough to source elsewhere, but the thread inserts are a bit harder to find. How can Unior be the only ones that make them at 9/16" 20TPI?

Thanks for this tutorial. I just bought a vitus nucleus and ony first ride pedal gor loose and came a bit off. Then i noticed a bit stripped thread. Can I claim warranty on this?

I keep stripping the pedal on the left side of my bike thank you for the information

thanks i will apply this also to my mtb. same isue 😐 i hope i can fix also

Can this be done on a fork for stripped brake calliper bolt holes?

Realky Thanks , it saved my bike, and just for only 50€ ( 40€ for the tap and 10€ for the insert )

Are all bike pedals the same? 9/16? i got the inserts but my pedal doesn't seem to fit the insert.

Can I use this method on an exercise bike?

I have a carrera vendetta what size should the thread insert be?

where can I purchase a pedal re tread kit and the cost pls thanks

Hi, Nice video. Very clear. I wanted to ask you if you think I machine a bushing with 1/2 20 TPI threads inside and )/16 outside soI can fit a set of 1/2 pedals into 9/16 crank without adding extra length as it’d happen ifI but the adapters available in the market.

Thank for video. I'm having trouble locating a kit on line. Or did you buy the parts all separately?

How long it will hold the bushing?

I think I can fix my left stripped crank arm myself; however, I would prefer a professional. Now I know what repair to ask for.

I find that any existing thread from back side of the arm is a good quote for the thread cleaner/cutting tool

Thanks for the video, how do you cut the extra thread, mine keep hitting the chain.

When you get to the thread making you should move forward a couple turns and then reverse the same. this removes the cuttings that can compromise the new thread.

My guy listening to candy paint😎😎respect

The grey grease is likely a molybdenum disulphide (moly) based grease. They are very slick and grey colour like what you found.

Hi there great video, could you please tell me the exact kit and tools/items i need to carry this repair out ? Thanks in advance

I’m having some trouble finding the coil thread kit. Do you have a part no. Or like for those? Thanks for the great videos!

Hi thanks for the video. Unfortunately the tool is no longer on the UK version of amazon and the company that makes it hasn’t gotten back to me. So I had to order separate parts from a German bike company, hopefully it works. Cheers.

What kind of grease do you recommend for the pedal ends (assume new pedal and new crank arm)? thanks

Curious if basically same technique would work on front wheel "plug and play" threads that are stripped? Brand new bike. LBS installed front fender. I removed fender to check on a front end noise and when went to reinstall and screw I tried several) won't line up with the hole. Is it just a matter of re-threading? TIA!

What size is the thread insert?

Where can i get the tools from to dl this guys

So when you do the other side you would use a different tool and go anti... sorry, from England! counter clockwise when making the new thread? Good video, good teacher.👍

Question: If I am repairing the left pedal instead (vs. the right in the video), does the coil and threading tool go in clockwise also? (I understand for the left side, the pedal tightens counter clockwise). Thank you.

I bought an ebike. I was able to smoothly install the left pedal but the right pedal got super hard and it wouldnt go in all the but like 3/4 of the way.

Boom! Subbed, I needed to look this up for work in the shop. You just hack off the extra or leave it on?

Maybe a silly question but I have just bought the same parts for my left pedal. Do I need to screw the tap in anti clockwise? I'm a little confused and don't want to do it wrong way and wear it away

Would this work on a stationary bike as well? I'm concerned about getting the right size if I buy from Unior

Thanks for posting! I recently damaged my brand new XTR 9120 L crank and stripped most of the threads. I use it on my enduro MTB. Ive had bike shops tell me the crank is finished and don't use a bushing, but this looks very solid. Do you think there are any safety issues with this? I'm definitely tempted to give it a try considering how much $$ these cranks were.

Can you use the insert for the sides the right and left pedals?

Just came across this video notice it said San José 👍🏽 I’m from here.. So just bought a bike pretty much new. The bas is both pedal and crank tread are both gone so you said if pedal tread is gone toss it 😆 so now does that mean I need to buy new right side pedal and also the kit to fix tread on crank? Can I just weld the pedal on?

Do bike repair shops do this kind of repairs? I live near a bike shop but they're closed right now. Thanks.

I actually have a problem with a new bike, new pedal where the right pedal won't screw on the right side. Any tips?

Great video. Have a 15 year old that needs to repair his Schwinn Discover Hybrid Bike 21-Speed, 28-Inch Wheels, any recommendations on what parts we need to order?

You'll find this alot easier if you take the crank arm off first, then hold it in a padded vice. Then using a long handle ratchet set, and cutting fluid.

I've got a Pedal Crank Thread Repair Bush Bushing Insert 9/16-20 and size tap thread do I need for my Crank for it to fit in

Thanks but my fatbike too broke my bike pedal treads broke what type of treads i need ?

I did all the steps then I tried to put insert in and it would not go in smoothly like your did. I added some grease too but I couldn't get the the insert in all the way. Any ideas?

Do you have videos about installing a crank arm?

What the size of thread replacement, and the size of tapping tools?

How sturdy are these inserts? I just stripped my left crank arm and the kit was more than a new crank arm set I found on ebay. Before ordering, I called a LBS to see if they'd do it and they just recommended a new crank arm, since he felt one or two good pedal strikes would ruin the insert. Thoughts?

Will a new pedal be needed to fit the fixed hole?

Size of tap for heli-coil ？

I have a 9/16” interior diameter 5/8” outer diameter 20-tpi thread insert. What exact pedal tap should I get as in size and tpi? Please help because 9/16” as described in the video description for pedal tap was too small!

Would you recommend using JB WELD instead of threadlock

So the thread kit is 9/16 and bushing or helicoil is 5/8?!

Hi, I need some advice. My bike's right pedal crank arm's thread stripped.. pedal thread size is 9/16, 20 TPI. What's the size of Thread Tap I should use for the crank arm thread? I tried with 9/16, but the thread insert (9/16 20 TPI) is not going in... Should I use 5/8 20 TPI for crank arm thread? Thanks in advance..

How about installing helicoil on Shimano crank arm pinch bolts? I find myseld in a situation now that I've stripped those pinch bolt areas as I kept on removing and reinstalling for a deep clean.

Hi, What if majority of my threads are ok? I had screwed up and now my i cant seem to get it past the first few

Hello, So if the hole on my crank arm is 1/2" do I purchase a kit the same size or do I purchase one that's a little bit bigger ?

Great vid! Rather than turn a socket inside out, I would have grabbed a 12 point socket.. I'd think that would work and be more snug?!

Can i know what's the thing that you put inside of hole of pedal?

hi, what size is the tapping rod?

Would this work to fix stripped threading on an ebike where you attach the crank? Right now it goes in a bit crooked and falls out pretty quickly. Tried quickweld but didn't stay, gunna try green loctite if I can't do this.

So will this work for my exercise bike?

What should I do if the threads are somehow bad, they keep the pedal but the pedal axle is not completely horizontal, it stays a bit bent.

Are all bikes the same size threads I have 26" beach cruiser

Very helpful! I didn't know what to do! I was getting My 10 minutes in on my Exerpeutic Recumbent Bike. I knew that Left Pedal was wobbly, tried to tighten it up to no avail. Anyway, the pedal fell off... I'm going to get supplies I need. Amazon was out of kits and didn't know when they'd have them. I feel knowledgeable thanks to your informative video & links. Just have to find the tools. Hardware Store, here I come! Thank You Very Much...

The pedal tap size is 9/16", a threaded insert of the same size was placed into the new hole. A pedal with the same dimension of 9/16" will fit into that insert. That's what I am understanding. But if I attach the pedal directly to the crank arm with the newly threaded hole, will the pedal still fit? I am a little confused...

is the loctite 277 good??

Hi so do u need the helicoil, cause i cant seem to find them anywhere...

What If the first 1-2mm of thread is damaged on the pedal? Can it be reused?
