- Series make your own tools : I show how to remove your crank arms without the special tool. Without causing any damage. Using nothing but a piece of pipe, a bushing (or socket) and a bolt. I also show you how to create a bearing cup wrench. This will work for extremely seized crank arms where the actual tool will destroy the crank arms and probably itself. In the video i use the following: Gas line or fence post PIPE: 5"1/4 inches long, outside Diameter (OD) 1"5/8 inches with wall thickness of 1/8" inches (3mm) BUSHING (or socket) 1" inch long with outside diameter (OD) of 3/4" inch and inside diameter of 1/2" inch with wall thickness of 1/8" inch The BOLT used is a low grade 1" 1/2 inch long with 3/8" inch wide threads.
my other crank removal videos: other video's showing this • Remove cranks without ... and • Remove cranks without ... and • Remove cranks without ...
Correction : for the right crank arm (drive side) turn the bearing cup clockwise due to it being reverse threaded.
Also, i mention you dont need a tool to remove the left side (non drive side) bearing cup, however if it is stuck you can use a wrench over the flats of the cup in most cases. If there are no flats then use a flat screw driver to hammer the cup to unscrew. If you are dealing with an aluminum frame the bearing cups may be ridiculously tight as shown in the video of the supercycle bearing cups which had to be hammered for about an hour before they started to slowly unscrew. make sure to use a very large and solid flat screw driver for this and be persistent as its possible the cups will never really turn easily as was my experience with this supercycles bearing cups. Before you re-assemble the cups into the frame, grease the threads of the cups and inside the threads of the frame this will provide a moisture seal and prevent seizing and cold welding. For full transparency the left crank arm (prowheel brand) polished aluminum (not shown in the video) of the supercycle shown was hammered off with just a hammer on the inside of the left crank arm. If done carefully and with a limited amount of force then absolutely no damage will occur except cosmetic damage to the inside of the left crank arm. This will give you better access to remove the non drive side bearing cup IF it is severely seized. In the case of the SR suntour cranks shown i did not want to risk damaging them by hammering on them plus the degree of cold-welding was much more severe then the supercycle which instead had seized bearing cups.
Thanks, I got them off! Can you add the steps to weld my frame back together?
Hahahahaaa
Dude, that's the best video on this subject that I've seen so far.
You didn't just show how to do something, or pointed out things to consider, (many others do that too), but you've also opened up new ways to approach things, (at least for me:).
Thank you.
ill save everyone the pain:
-UNSCREW BOTH BOLTS ON CRANK ARMS
-UNSCREW LEFT BEARING RACE
-BELT SHAFT FROM OTHER SIDE WITH PUNCH & HAMMER.
-DRIVESHAFT & BEARINGS WILL POP OUT
Should I also cut my frame into a hand size section and secure it into a vice?
@@uidx-bob Yes - but be sure to take absolutely months to show how when you make the vid. No rush - honest.
I did everything he said and does...and it works...my problem now is how to weld my bike frame back 😬
lol
Finally a man who actually knows what he's talking about.
Jesus this was painfull watch
ya it was my 2nd video ... a bit too long. just too lazy to re-do it : P
@@BIKEMAN21 I think he's talking about the damaged bike 😂
You are an excellent teacher, thanks for your video
VERY HELPFUL FOR THIS NEWBIE, THANK YOU SO MUCH!!!
You're welcome, thanks for watching !
I gotta admit...u got brains man 👍🏽
Ive been deaing with this prob cuz i dont have a crank puller
I already broke a thick screwdriver like yours in half
Thx so much 😁
Right on ! I came up with this method after I found aluminum bike with Alloy cranks. The problem was the crank arms were hopelessly seized, even if i had the puller it probably would not work. And my usual go to method of hammering on the inside of the crank arms was out of the question, i wanted to re-use the crank arms. During a search of youtube i found everybody was showing methods that were quite bad so this is basically my first video.
Well i still didnt manage to remove from my other bike 😔
Do u see what u did at 1:07 i cant do that cuz its plastic , i tried to loose it with a grip tang and it just wont turn 😕
@@iseayabrucedolieveira4032 You may have a different type of bottom bracket such as hollow tech or something.
This vid has excellent points, i would add that using bbq lighter style butane torch from Costco on the outside of the crank (arm)will make its removal with a hammer easy with a slight tap. Thank you.
All I want to know is how you removed the left crank arm? By the you started, yours was already loose. I removed the nut, but it's still not coming off
You may be used to the Bird noise but my earpiece isn't!
REALLY GOOD ADVICE HERE,CHEERS FELLA
OMG, The bird is trying to advise😮
That's clever. Thank you
Out
I want to say thank you I had to hammer just a little harder. I followed the steps and its off like that thanks the old bike can now get repaired with the other bike I took apart. what fun its going to be to put back together a Bianchi
My bike paddle drop with arm from crank shaft. I tried lock tite on threads but after five min ride arm drop with paddle.
Left side where no chain is there please advise.
sounds like the arm is damaged. Hammer it on and keep tighening the nut while riding it. make sure the nut does not get loose, lock tite will not work for this because the taper will always loosen the nut, you have to keep tightening the nut in your situation because your arm is slightly damaged. After a while it should be ok.
holy shit thank you so much, just spent like 4 hours frustrated trying to wack it off like a caveman. found this and it worked like a charm
OMFG that hurt my brain to watch your incompetence
QUESTION: I am looking to replace the left crank on a bike and got one that is a different weight than the original. The original crank is pretty heavy in comparison to my new one. Will this weight make a difference when riding the bike?
Thank you for your video!
nah it will work just fine
Part tool CWP-7, $15.00 could save you time and problems
you can't use that when the threads are stripped!
@@techjunkie68smusicandtech56
Then you might as well just angle grind them off
Errr.. if everything's already loosen before .. then you don't need tools .. most bikes nuts and bolts are probably stuck if we are searching for videos to remove a crankset ;).. update: yeah @bikeman mentioned about loosened screw in the first place. ;)
It was already loosened and I still couldnt unscrew it, I was pretending it was seized and trying to figure out how to loosen it. but i explained it in the description : P
@@BIKEMAN21 oh yes. Apologies. !
@@ryanyoutube7315 if your bottom bracket is aluminum it can be seized if not serviced in long time. at that point it may be required not to remove the bearing race on the drive side because it wont come out. Ive got other video's showing this czcams.com/video/XLjbaymxH-E/video.html and czcams.com/video/FagZ6jh_W1M/video.html and czcams.com/video/Jgn1ee3BGDg/video.html
I got a easiest way just remove carnk bolt and ride the cycle around your house after some time it came lose
The damn bird is the anti-christ! 100% lol It's driving me mad. Lol
It's like watching an episode from Thunderbirds.
What is that Fing squeaking?
Ah yes now I can go back riding 👨
I'm curious why you wouldn't take the crank arms off FIRST. Won't there be a bigger chance to cause damage because of the bottom bracket bouncing around?
bro thats what we are trying to remove lol
@@310smoker hahah lol
Damn that shit started kinda simple then bam bam bam you're 30 steps in wanting to quit
This is the non destructive method for aluminum cranks, if they are metal, just tap the insides gently with a hammer many times, vibration should release at least one of the crank arms, then just remove the bearing cup..
The bird disagrees.
That's great! No special tool besides making one from scratch. Do you have a pet rat in background
lovebirds, no rats lol
i got a rat , they just as messy
😀👍
Yup this actually works, i haven't seen anybody on CZcams disassemble an entire crank without the special tools. my way is better because the actual tools could damage the crank arms.
@@BIKEMAN21 it's how I've always done it . although I do leave the nut on it . and hit the outside of the nut ,to keep from mushrooming the axle. And instead of a punch.
I use a smaller socket and whack it. But I just like you fooling around with the bikes it's cool to watch. 👍
@@Jarrod_D Nice, what i found is best is to never leave the nut on, or bolt, inside the crank axle, as the only part that is strong here is the axle. I've never seen a crank axle get damaged from hammering, a pedal axle yes. But the crank axle seems to be much stronger and harder than any other part on a bike.
@@Jarrod_D You are going to strip the nut like that i think. I Havent tried it on the nut style though. but if it was a bolt it would strip immediately.. tried that.
@@BIKEMAN21 put the flat of the socket against the nut and the axle .back.the nut to the top of the axle to keep it from mushrooming. And whack the socket. That's how I do it.
no damage? look at the frame!
ya I dont know what happened there
Erase this.
Don't do heroin people 🙈
drugs bad except those mandated by the axis of evil
this is very painful to watch
You already had stuff loosened.isnt that why we are watching.awful
So slow lol
: P forgot how to do it lol
It's TRUE... when I go work on bikes without a camera I know what I'm doing but with a camera it's like, ah what should I say .... hmmm. And then i start shuddering
Noooooooooob
