    Thaaaaaaaaaaaaaaaaaaaanks…. u amazing

  3. Matthew Kent on July 6, 2019 at 8:32 pm

    Rip me when I was torquing down one of the cranks my torque wrench broke! The tip literally broke off.

    I found this really helpful for removing the crankset from a 2006 Bianchi 928 with ISIS bottom bracket. I bought the Park crank remover but didn’t fully understand how to use until I watched this video. Of course one common issue is that you can’t get the crank bolt out after it’s been in place for a decade. Impact driver worked well to get the project started. I agree with other comments, that this guy is really good.

  6. limyohwan on July 6, 2019 at 8:36 pm

    never knew that not lifting could come in handy. Now i can just jam it as hard as i can without exceeding the recommended torque!

  7. Jared Gulaga on July 6, 2019 at 8:37 pm

    Instead of using a crank remover couldn’t I just use a hammer?

  8. Filip Tideman on July 6, 2019 at 8:40 pm

    Absolutely amazing, thanks Park Tool!!

  9. Engela Conradie on July 6, 2019 at 8:41 pm

    What if the crank arm is seized?

  10. Jamey Lane on July 6, 2019 at 8:43 pm

    Note that on square tapers, tension from the bolt is not the only thing keeping cranks from creaking. Initial tension on the bolt keeps the crank arm from migrating down and rounding itself – at which point no amount of tension on the nut will be a lasting fix (so don’t jump on top of your allen wrench and pray – it won’t work). You MUST keep the nut tight and check them, as riding on it "popping" under load will round out the soft aluminum of the crank arm, and it may be already too late if it pops (need new crank arm). Now this can happen also even with good bolt tension if the arm or taper shaft are out of spec to each other too. It can also happen on it’s own with heavy force exerted (or high rider weight or high miles) as it’s aluminum (arm) on steel (taper shaft).

  11. Morning Riders on July 6, 2019 at 8:43 pm

    Is there any alternative to remove the crank arm if we dont have crank remover?

  12. jack4688 on July 6, 2019 at 8:48 pm

    As per the display of crankset types at 4:12 my bike has an 8mm bolt and I should be able to remove the cranks with the CWP-7 but for the life of me I can’t get it to screw on to the thread of my cranks! I am absolutely sure it won’t go on and that what I have removed indicates my CWP-7 should work but the threads don’t seem to match up.

    I have a GT Avalanche 2.0 and the cranks themselves appear to be SR Suntour items but I can’t find any further details on them, for instance if I have a model of Avalanche that was supplied with cranks that have some obscure, seldom used thread size.

    I am removing the cranks, crankset and bottom bracket to convert my bike to electric pedal assist so I can remove them and sacrifice the cranks if need be, but can anyone advise me how?

  13. KP Schulze on July 6, 2019 at 8:49 pm

    great man,great explanations ,everything is much clear..thank you!!

  14. AngusB Liddell on July 6, 2019 at 8:49 pm

    do you need a special tool to remove the crank or are there other ways ?

  15. Vali Munteanu on July 6, 2019 at 8:50 pm

    Amazing. Cutting the pedal arm to see inside was brilliant.

  16. Carmen Herrera on July 6, 2019 at 8:51 pm

    Do you have a video for the sealed bottom bracket and removal, service and installation for shimano octalink?

  17. David Duganne on July 6, 2019 at 8:52 pm

    Very good video. If you’re upgrading to another crankset, be sure to pull your pedals off first, before removing the cranks from the BB!

  18. Pete McKinlay on July 6, 2019 at 8:54 pm

    Hey Calvin and team,

    Quick BB question for you- I just replaced the BB in my training bike with a Shimano BB-UN55… The non-drive side went in really easily, but the drive side was a right pain, and I couldn’t get the outside of the shell to bottom on the BB shell. I couldn’t apply any more torque without the BB tool popping out of the drive side.
    I used waterproof grease, and my 5 minute test ride was a 1000% improvement on the old BB… But I still feel like that BB shell should be seated on both sides. The only thing I can think is that my BB tool is a bit crappy (a SuperB from about 10 years ago) and might have stopped me from driving the whole way home.

    Have I done something wrong, or if this OK?

    Thanks for the content,it’s always fantastic 🙂

    Very informative video. Thankyou

  20. Geofan on July 6, 2019 at 8:57 pm

  21. emperor's paradox on July 6, 2019 at 8:59 pm

    I cant remove my crank fck

  22. Casey Neistat on July 6, 2019 at 8:59 pm

    Thank you.

  23. Spencer Marfing on July 6, 2019 at 8:59 pm

    I’m repairing a bike my Dad gave me, with very little bike maintenance experience. It’s a sentimental project which is why I didn’t opt to take it to a shop. I went to my local bike shop and explained this while asking for some tools. The employee directed me to the items I was looking for recommending Park Tool, adding that they had great video explanations. After watching this, I couldn’t be more happy with every dollar I spent towards this company. My project is well underway and I will definitely turn to Park for further tools and resources.

    Thank You!!!

  25. dellam04 on July 6, 2019 at 9:01 pm

    Is one of the sides is the reverse thread?

  26. Rick Hindman on July 6, 2019 at 9:01 pm

    This video came in really handy, I have been handed the task of updating some tandem bikes to run on train tracks and need to pull several cranks off.

  27. bluebloodp71 on July 6, 2019 at 9:02 pm

    And that’s how you ruin a TQ wrench

  28. Rinyotsu on July 6, 2019 at 9:02 pm

    On the torque, where can the torque spec recommendations be found for each bike? I have a breezer thunder 26" and a trek 8.2 ds as my main bikes (I also have a hyper shocker 26" I got for free that I’ve used as a bike to tinker with so I don’t feel too bad if I mess up because the original owner broke the rear derailleur).

  29. Kyaw Tun on July 6, 2019 at 9:05 pm

    Thank you so much for every single video, It is really helpful for me. The way you teach is I feel you come and teach infront of me. Perfect teaching and presentation. Love you😃.

    Brilliant commentary and easy steps demonstrated. Thank you very much.

  36. TheSkystrider on July 6, 2019 at 9:10 pm

    I don’t understand why the crank removal tool I bought only works for square taper… I need yet another/different crank tool for a Specialized bike?! 🙁

  37. whatathon on July 6, 2019 at 9:10 pm

    I buy Park Tools exclusively now because your video series on Youtube is so good. Thank you for putting this knowledge out there, these videos are incredibly helpful.

  38. RandomRoulette on July 6, 2019 at 9:10 pm

    Cant I just use a hammer and whack it off?

  39. MJ Fuwausa on July 6, 2019 at 9:12 pm

    How much torque for a square spindle?

  46. Bard on July 6, 2019 at 9:21 pm

    My crank fell off and I lost the crank bolt, was not sure if I could fix it myself with out proper tools. Thanks for the video, I think I may be able to do it, off to the bike shop!

  47. Ricardo del Rey on July 6, 2019 at 9:22 pm

    what is the size of the spindle length in the beginning of the video where you cut away part of the arm to show what the inside looks like? thanks.

  48. Ferda Boys on July 6, 2019 at 9:26 pm
