How to repair stripped pedal threads on the crank arm with Unior bushing and a pedal tap.

How to repair stripped pedal threads on the crank arm with Unior bushing and a pedal tap.

How to repair stripped pedal threads on the crank arm. In this video, I use the Unior pedal tap repair kit. It comes complete with the two in one reamer and thread tap and the left and right bushings (Helicoil). You just need to purchase a heavy-duty thread locker such as Loctite 271 Red and a T-handle tap wrench to fit the reamer. Down below is the link to locate the tools and the parts. Please shop around before buying it​.

    you didn’t add the link for the bushings



  2. Mike B on July 23, 2022 at 11:17 pm

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



  3. N P on July 23, 2022 at 11:17 pm

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



  4. RIMURU FF on July 23, 2022 at 11:19 pm

    Can u give me the links to buy them 🥺



  5. Gary Hee, owner, Paramount Computers Ltd, on July 23, 2022 at 11:22 pm

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



  6. Amirul Production official on July 23, 2022 at 11:23 pm

    What size of coil



  7. Lenient Bus on July 23, 2022 at 11:23 pm

    Does any know what size of pedals I would use after doing this



  8. LucidoMafia on July 23, 2022 at 11:25 pm

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



  9. Santo Sakowski on July 23, 2022 at 11:25 pm

    Thanks for the very informative video. However, after checking the prices of the taps and pedals, I will probably just weld my pedal back on! Otherwise, I could buy a good used bike for the price of the materials needed!



  10. Krystah Nash on July 23, 2022 at 11:26 pm

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



  11. Eric Ramirez on July 23, 2022 at 11:27 pm

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



  12. Thenfly WJAZ on July 23, 2022 at 11:28 pm

    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.



  13. Shan Te Kani on July 23, 2022 at 11:28 pm

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



  14. Hakim Shakoor on July 23, 2022 at 11:28 pm

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



  15. AL Adigue on July 23, 2022 at 11:32 pm

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



  16. Shannon Moore on July 23, 2022 at 11:33 pm

    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!



  17. William Fher on July 23, 2022 at 11:33 pm

    Actually I got that part for $20 on Amazon. The tool to make the threads size is 5/8 . Make sure you specify for the right or left side . And the little insert adapter for the pedal is 9/16 (same size of the most standard pedals) and also you have to order it for the side you need . That little adapter cost me $6 .. total: $26 with taxes . You don’t need any fancy tools , just the regulars you have at home . And also you don’t need the lock tight liquid. This is just a bycycle and not a motorcycle .



  18. Sammyyy Vlog on July 23, 2022 at 11:33 pm

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



  19. deritha barber on July 23, 2022 at 11:34 pm

    Do you have videos about installing a crank arm?



  20. Nurashid Noor Mohamad on July 23, 2022 at 11:35 pm

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



  21. Alan Feekery on July 23, 2022 at 11:35 pm

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



  22. Jay R on July 23, 2022 at 11:36 pm

    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?



  23. Jamie Garcia on July 23, 2022 at 11:37 pm

    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 ?



  24. Derek Watts on July 23, 2022 at 11:39 pm

    Thank you this was really helpful.



  25. Adobe am Gray on July 23, 2022 at 11:41 pm

    Where can i get the tools from to dl this guys



  26. Canada Life on July 23, 2022 at 11:42 pm

    omg so much narration…. sometimes i feel like hes justifying the way he does things, instead of teaching



  27. CHARLEY BURIGSAY on July 23, 2022 at 11:45 pm

    Size of the heli coil sir and the tap?



  28. Smartness on July 23, 2022 at 11:45 pm

    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.



  29. Tarek Faham on July 23, 2022 at 11:47 pm

    I got a new bike paid C$400 and after a few days the peddle went off and I can tell that the thread on the peddle and on the other side are gone, what do I do now?



  30. Luke Williams on July 23, 2022 at 11:48 pm

    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.



  31. David Low on July 23, 2022 at 11:48 pm

    Why are you showing this operation when you can’t even buy this kit, how did you get this kit. I go online and I can’t even buy this kit, why is this stupid kit so dam expensive. It does not make sense. This repair is stupid you can’t even buy this kit why is this kit so hard to get.



  32. Michael JLR on July 23, 2022 at 11:49 pm

    so are there two scenarios when the threads are stripped? 1) threads are damaged but able to be saved by cleaning and re tapping original threads and pedal, option 2 is there are beyond repair and need the union bushing and new wider diameter threads.



  33. Neil Thompson on July 23, 2022 at 11:50 pm

    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.



  34. Kali on July 23, 2022 at 11:53 pm

    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 & YouTube comes with this today !

    SCARY AI & Tech !



  35. Mark Lester Gamayon on July 23, 2022 at 11:53 pm

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



  36. Joey Joey on July 23, 2022 at 11:54 pm

    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..



  37. Jason Fyfe on July 23, 2022 at 11:54 pm

    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



  38. احمد on July 23, 2022 at 11:56 pm

    My crank is damage by pedal, can you tell me the causes?
    Thank you



  39. deritha barber on July 23, 2022 at 11:56 pm

    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?



  40. Tojo Rabemananjara on July 23, 2022 at 11:58 pm

    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!



  41. Yan myo maw on July 24, 2022 at 12:01 am

    can you provide me a link for thread insert?



  42. Kaywood Parsons on July 24, 2022 at 12:01 am

    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.



  43. Kassum Smith on July 24, 2022 at 12:01 am

    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



  44. Real Deal on July 24, 2022 at 12:03 am

    it might be ok ,but much cheaper and better way is to tig hole slightly closed , drill 33/64 bit and then use a tapered tap with 9/16 and retread again bingo done . Theres many tig rods types that are good and strong aluminum alloy .



  45. Manx Missile! on July 24, 2022 at 12:03 am

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



  46. Clint East on July 24, 2022 at 12:04 am

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



  47. Mud Trail on July 24, 2022 at 12:09 am

    Great video, clear explanation!



  48. mercedes walt on July 24, 2022 at 12:09 am

    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.



  49. Nigx Vic on July 24, 2022 at 12:10 am

    Can I get this in Amazon



  50. Reece Kurman on July 24, 2022 at 12:11 am

    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
