Thank you so much for this video I am restoring a Columbia road bike from 1970 something and I use to work on bikes all the time but haven't worked on vintage bikes in years and forgot how to do basic vintage bike repairs this really helps thanks
Really appreciated the video. Thank you. Please note based on this video I bought the HCW 18 wrench. It probably works on a Schwinn, but the span was too wide for my old Western Flyer tandem.
Holy cow where was this 5 years ago for my super old MTB one crank I figured it out on my own took some time. New Bearing were cheap thou :) I removed the Cups with a Hammer and a Stick, then I reinstalled them with a Hammer :)
I noticed that in my country, all these bottom bracket cups have a really small inside diameter hole, so it's not possible to take the crankarm off without hammering one or both cups with a wrench. I already worked with old and new bikes, watched a good amount of videos about this BB and never seen a cup like this in the video
Thank you so much! Best video, and I have watch too many. Very well done! Love your care to explain as you go! I feel more so much more confident to do this next week when my bearings arrive.
how do you remove the cups from the frame? I have a complete new kit, and I don't want to leave the original cups in, if I don't have to. Love your videos BTW. I am learning soooo much.
Is a little bit "better method" to just install loose individual bearings, so MORE bearings are sharing the load? I know to do that you'd have to have the frame laying on its' side to keep the bearings from falling out. Thank you again!
I have a folding bike with this kind of bottom bracket cups, but the crank is a three piece?? What would I do if I want to replace it with something more modern? It doesn't seal at all so it gets creaky even if it just gets wet.
Thank you! I was thinking I would never figure out how to remove the pedals from this bike. Turning it into a plow but the plow video didn't show how he got the pedals off
I'm trying to do a bafange mid Drive I need to know what size adapter I need to make it fit I think it wants BSA but I can't find it an adapter that fits my bottom bracket and takes me to the the thing mid Drive
Great video, can you help me with a brand new bike - one piece crank that wobbles in casing - Huffy Cranbrook. Can I just tighten to secure more? Can't budge the 30mm piece, so thin and hard to grasp. Can I turn it to tighten? Or is it the other piece with the 2 notches and needs a special tool?
Hello, I have a 1 piece crank but my chainring is rubbing on the frame. Is there any way i can put a spacer for it not to rub? If so where do i put the spacer
I have the same style on exercise bike and even i follw installation perfectly it always come loose even after using double nut and loctite there is always play from side to side after 3 or 4 hours of using the bike from thigthenig the bike
How to remove a stubborn lock nut? I used the spanner counterclockwise at first to remove it and got it ready stuck! I should taking notes from this video to clockwise my turns to loosen it. The lock nut is worn out. How do I remove it and the worn locknut?
Arrange yourself and the cranks for best mechanical advantage. If you stand behind the bike, have the right arm face to the back. Select the wrench flats that will have the wrench face to back the back. Reach over the frame (or through the frame) with your right hand. Pull up on the right arm while pushing down on the left. Keep the wrench straight and apply force. Two arms moving opposite direction.
Kind of think that this old fauber crank had it's good sides compared to todays hollow tech bearing which wears out pretty fast and you have to buy new bottom bracket which on the other hand is not so expensive.
It matters which way the cage is facing. The open side should face the cone. The wrong way will mean the metal cage rubs against the bearing surfaces, rather than the ball bearings. Put the cage on the cone, and spin it. Now flip it over and spin again. One side rolls on the ball bearings, that is the correct orientation.
FORGOT RUST. Greatly helpful, but If were new to this on a 50 year old bike there's a solid chance that cone ain't sliding off like it does on camera. It would be nice, and realistic, if you included assumed rusted threads and solidified grease removal in all of your vintage parts videos. My answer was hammer, screwdriver, steel wool and an hour of toil so I would love to find an easier solution next time around.
Typically when a crank arm becomes loose on the spindle of the bottom bracket it will need to be replaced. They will continually come loose. New arms are fairly cost effective from a local shop or online if you know the length and the orientation of the square.
The caged bearings for the One Piece crank sets are not universal. If you are replacing the entire unit with cups and cones, it should come with new bearings to match.
can a one peace crank be replaced with a different type? im looking to replace the one on my bike with a crank with a free wheel sprocket for a project of mine.
There are adapters that be fitting into the large shell that reduce the diameter to the common BSC threading (1.37x24). A cartridge bottom bracket can then be installed.
I was able to successfully remove my one piece crank from my bottom bracket and take everything apart to replace the bearings, but I have no clue where I can find new bearings. Where can I find these bearings for a 1979 Schwinn suburban? I don't know what size they are either. The bearings have a code on them "6178a" if that helps at all. Thanks
Can these types of cranks be upgraded to something better? I got a free Murray that has this type of setup. Would like to make it a bit higher tech. I know it's like putting lipstick on a pig, but it's for an ebike I'm building.
NUTS. Every video I find isn't showing me what I need. I'm trying to REPLACE the crank arm. HOW do you get those parts OFF the opposite side???? Mine wont budge. Then again, I see a special tool you folks use. Not sure what that's called or where to find one.
The crank needs a crank remover tool, also called a "crank puller" or "crank extractor". For the three piece cranks, the arm is pressed tightly to a spindle. The bolts are remover, but then a remover such at the CWP-7 is used to un-press the arm. www.parktool.com/product/universal-crank-puller-for-square-taper-and-splined-cranks-cwp-7
The cone on the driveside is removed either with a large wrench or a vise on the wrench flats on the outter most part of the cone. Or sometime there are notches for a spanner tool.
after ungreasing and regreasing whenever i pedal it gets stuck while turning like somethings pushing against it making it wayy harder to pedal and makes a sound like medal is touching medal any help anyone?
You are on the right track. Hammer and a large punch from the opposing side is how these are removed. Might need a slightly larger hammer and to walk it out hitting one location and then a location 180 degrees from it.
@@parktool yes I had to go to a bigger hammer and bigger pice of pipe that covered the entire cup from inside and still had to give it 3 good hard hits before it popped out. The inside feels and looks was glued in place
Man, you are saving lives with these videos! Love the effort you put in. This is so clear and easy to understand. THank you so much
He's saving my wallet! Just to add!
Thank you so much for this video I am restoring a Columbia road bike from 1970 something and I use to work on bikes all the time but haven't worked on vintage bikes in years and forgot how to do basic vintage bike repairs this really helps thanks
Another great video from Calvin Jones, clear and accurate, not a second wasted with useless words. Thank you!
I really appreciate this video. Very simple, straight forward, easy to follow.
The most detailed example of removal and Install so far 👌
Funny when I'm doing jobs on my bikes I normally watch the video first and then have Calvin's unique voice playing in my head 😆 great videos
Thank you Calvin! With the explanation I didn't fear of a possible bad installing after.
Thank you very much for sharing your knowledge with us. It's been many, many years since I've done this work.
0:26 30mm? I think you meant 32mm 😉
I love one piece cranks, though these days the bearing outer cups are a bit soft.
Love this video. Clear easy to understand instructions. Thank you!
Thank you park tool, without your vids i wouldn't know how to fix my bike
Thanks. I followed your instructions and fixed my problem.

If I want to convert this to Hollowtech bottom bracket how do I size it?
Thank you so much!!! ♡♡♡ I took apart my daughters bike to repaint it and got stumped putting it back together!

Hey Kal thanks for the great lessons 🎉
Great video. I needed this to fix this broken Schwinn falcon crank. It got ran over and the crank broke where the pedal starts.
Thank you so much! Best video, and I have watch too many. Very well done! Love your care to explain as you go! I feel more so much more confident to do this next week when my bearings arrive.
Thank you so much. Information in detail. Thanks a lot again.
Thank you, you are a great teacher
Is there a video showing how to upgrade from The one piece to a different type of bottom bracket
No video on that yet.
how do you remove the cups from the frame? I have a complete new kit, and I don't want to leave the original cups in, if I don't have to. Love your videos BTW. I am learning soooo much.
For these one-piece system, use a punch and hammer to drive out the cups.
Awesome video!! Thanks for the info!!
Thank you so much this video was exactly what I needed!!
Thanks for the easy to understand presentation!
это самое полезное и подробное видео по разбору данного вида шатуна. Спасибо большое. половину РуНета переискал, спасибо.
Runet govno, Putin huylo
Thank you for this. I could not figure out how to get the cone tight so it didn't wiggle. I didn't know working on bikes was that complicated lol.
So awesome and thorough. Thank you!

Do you take out the cups or just replace the bearings thanks
Thank you! I was thinking I would never figure out how to remove the pedals from this bike. Turning it into a plow but the plow video didn't show how he got the pedals off
It doesn't need to be tighten on the drive side?
Only the facts. Great detailed video.
I'm trying to do a bafange mid Drive I need to know what size adapter I need to make it fit I think it wants BSA but I can't find it an adapter that fits my bottom bracket and takes me to the the thing mid Drive
Nice old Schwinn Super Sport

Pregunta: ¿Se puede reemplazar con "Press-Fit" en caso de que se acaben este tipo de componente?.
Gracias.
Parts for these cranks and bottom brackets are still available. The bottom bracket is a press fit but cannot be replaced by a newer pressfit standard.
@@parktool Oh. Entiendo. Gracias.
How do you install the cups though????
What is the pluses and minuses of a one piece versus a three piece?
That really helped me understand how to service mine
Gee that was a great video. I can fix my kid’s bike now.
I have the same style on exercise bike and even i follw installation perfectly it always come loose even after using double nut and loctite there is always play from side to side after 3 or 4 hours of using the bike from thigthenig the bike
your videos are great
Huge fan !!
Are the cups replaceable on this bike ?
Yes. Use a punch and hammer from the inside. Use a press to install new one, greasing the press interface.
Where can I buy a whole new crankset from scrach
How does the main gear come off as I snapped the pedal of my one piece crank
If you have a one-piece crank, the right side bearing race is threaded to hold the chainrings. Loosen this nut to remove the rings.
SOO helpful. Thank you

Can you do a video about swapping a one piece to a 3 piece?
This is just for one brand of converter.

Can It be replaced with external bearing bottom bracket? thanks
There are adapters that can be pressing in place that accept threaded bottom brackets. The external bearing style can then be installed.
@@parktool Thanks for the reply, what's the name of the adapter ? It looks like a double threaded ring, doesn't it ? Kind regards.
Thank you. You save me 70 bucks today :)
Thanks а lot for the helpful video 🤝
does it matter wich way the ball bearings are facing
It matters which way the cage is facing. The open side should face the cone. The wrong way will mean the metal cage rubs against the bearing surfaces, rather than the ball bearings. Put the cage on the cone, and spin it. Now flip it over and spin again. One side rolls on the ball bearings, that is the correct orientation.

I had to constantly buy new cage bearings because I wasn't reinstalling them right. Thank you.
Thank you.
All the left hand side lock nuts on one piece cranks i have experienced have been 32 mm.
I have a bike with this crank arm. However, it is loose and wobbles when pressure is applied. When I open it, what should I do to fix it?
Typically when a crank arm becomes loose on the spindle of the bottom bracket it will need to be replaced. They will continually come loose. New arms are fairly cost effective from a local shop or online if you know the length and the orientation of the square.
I need to swap bottom brackets from frame to frame and cant seem to get the cups on the new frame??
For this style, the cups are tapped out with a punch. The cups are then pressed into a new frame using a press.
Very beneficial
Hello, are the shell, cages bearings universal size ? I want to replace the whole crank set because the chain ring is bent
The caged bearings for the One Piece crank sets are not universal. If you are replacing the entire unit with cups and cones, it should come with new bearings to match.
Nice demo. Thanks.
Super helpful. Thank you!!

There are adapters that be fitting into the large shell that reduce the diameter to the common BSC threading (1.37x24). A cartridge bottom bracket can then be installed.
awesome, thank you for the information.
this is for a 50mm bottom bracket, because in a 45mm you have to remove the cups from the frame to remove the crank arm
I was able to successfully remove my one piece crank from my bottom bracket and take everything apart to replace the bearings, but I have no clue where I can find new bearings. Where can I find these bearings for a 1979 Schwinn suburban? I don't know what size they are either. The bearings have a code on them "6178a" if that helps at all. Thanks
I believe they're universal and that you can take the old ones to a bike shop and they can get you new ones that fit.
@@PatrickDSimpson yeah I was able to find them on eBay I believe
I had that exact Schwinn :-) Had to sell it, which I hated. Cool bike.
is there a substitute tool for the hcw 18 wrench for the left cone?
Danman_ 28 did u find it
Danman_ 28 have you tried using two flat head screwdrivers?
Can I replace the one piece with a three piece ?
Yes, you can install adapters the reduce the sizing and provide internal threading for the three-piece bottom bracket spindle units.
Can these types of cranks be upgraded to something better? I got a free Murray that has this type of setup. Would like to make it a bit higher tech. I know it's like putting lipstick on a pig, but it's for an ebike I'm building.
You sure can. We have a video on the adaptor. It can be seen at this link. th-cam.com/video/W9zPkrCtWEM/w-d-xo.html&t
@@parktool Awesome! Thanks!

Very good.
Is it a bb30 or pf30?
Neither. The "American" style is nominally 2" ID. It is an early press fit, but is not BB30 nor PF30.
Is it possible to switch out a two or three piece crank for a one piece?
The one-piece crank requires a very large shell. The bikes made for the two or three piece cranks do not come close to the size needed.
Park Tool
Sad to hear it, but thank you.
What size wrench for drive side cone. LoL
I’d go with a left-handed bockmist.
@@gregnixon1296 sure but which bike tool
He didnt take ot the last part. I cant get out my crank without that last ring removed. I don't have the tool
How to you remove the right site bearing cone with the chainring on???
Its the only part you didnt remove..
The cone on the driveside is removed either with a large wrench or a vise on the wrench flats on the outter most part of the cone. Or sometime there are notches for a spanner tool.
after ungreasing and regreasing whenever i pedal it gets stuck while turning like somethings pushing against it making it wayy harder to pedal and makes a sound like medal is touching medal any help anyone?
Double check the bearing retainer is not backwards
@@parktooldidn’t work, any other reason why?
Did happen to me when I bend or warped the caged bearing replace the caged bearing they are cheap
Thanks a lot!
It was hard to see how much grease to put in the bearing.
Good point. A Lot. Pack it in, just wipe off any outside.
Ok how do you remove the cups.
I hit one side out with a pipe and got it out but the non drive side is stuck on and I can't get it out
You are on the right track. Hammer and a large punch from the opposing side is how these are removed. Might need a slightly larger hammer and to walk it out hitting one location and then a location 180 degrees from it.

One piece cranks still far superior to all the rest why they change them is beyond me
Those cranks bend so easily when you jump on your bike
Bruh it looks so easy on video, But literally mine is just frozen on there no amount of PB blaster and hammering can free it.
the inverted bolts and threads make me so uncomfortable, I just feel sometheing breaking inside of me xD
Nice,thank you
