- Here is how to replace 1 piece BMX bike cranks with a 3 piece crank and a sealed bottom bracket. I also show how to Make a bearing press. It is easy to replace your 1 piece bike crank with a sealed bottom bracket and 3 piece cranks. Make sure you get
The right size sealed bottom bracket for your bike. The one in the video is American size. That is probably what size bottom bracket you have as well. The bottom bracket in the video is a Mechanik American kit with 19 mm bearings. The cranks are Sunday Saker cranks with a 19mm spindle.
Here is where you can buy a sealed bottom bracket and crank kit on Amazon:

Here is a 25 tooth sprocket to fit the crank set.

+Martin Binkier Thanks.
hoohoohoblin can you stage up to a 48 spline with the bearings n all? N is this 155 or 175mm?

Best american BB install video out
“Shut up jimmy”
Ion know why I’m watching this I already know how to work on bikes😂
8:25 “We actually could not figure out the equational of which way.. how.. we couldn’t take it off..”😂😂😂😂😂😂
“hey I have a pedal video too”😂😂😂
Thank you for this! I'm planning to do this on my '87 GT Pro Performer.
You’re welcome.
@5:36 shut up Jimmy!
Thanks 5yr old comment
You're officially voted King of Tutorials!! Great video! Highly detailed, step by step instruction was top notch! Thank you! 🔧⚙️🚴🏼♂️👍🏼
You’re welcome!
Hey...awesome video and very informative. I have always used 1 piece cranks and I am going to venture into the 3 piece and you made it too easy that I cannot mess it up.
I’m glad I could help. Good luck.
What rear rubs you have. Sound gorgeous.
I found the Sunday saker but it says it's a mid bb so we're did you find yours
There's also European size crank bearing as well
Jimmy needs to learn to shut his mouth...
+Gamingdaemon Ha ha!
+hoohoohoblin what tool did you use to loosen the nut ??? It's killing me

Awesome vid. My euro bearings broke and long term its cheaper to just get a new frame and bracket. Now i can use my old diamondback and turn it into something decent. Thanks
just finished. your video was very helpful.
Love this video to best tutorial.
Thanks
Thanks. But the link you sent me is a different one. I would love to buy the one that are in you're video.
canniggia morgan Sorry. We made the video a long time ago. I looked up the receipt, and found that it was a Mechanik 19mm kit for $19.99. Here is a link to it at danscomp. www.danscomp.com/products-PARTS/456061/Mechanik_BB_Kit.html
I this one of the better videos on you tube i think ive watched mainly cause when you watch a video explaining how to do something they treat you like your stupid but in this video is was good wasn't annoying and it helped inform me what i need to do with my bike
Riley Hayden Thanks!
*you're.
nioce. did not know you could upgrade the old standard 1 piece with shit ball bearings to the sealed bearings and 3 piece cranks. I may salvage one of my older bmx frames
You’re welcome. It isn’t cheap, but it can be done.
@@hoohoohoblin I looked them up on DansComp. Good price. And I already have 3 piece cranks from my other bikes. No big deal. Never knew about this. Thanks for sharing
Did the cranks come with bearings?
Hello would you point me to the same BB you bought from Dans Comp? I need to make this operation exactly as you did!
I put a link in the description to where you can buy one.
almost 3thousand views for 1pc cranks. that's interesting.
Yeah i have one piece cranks
Almost 8 years and still the best tutorial out here.👍🏼👍🏼 Did the kid figured out the equation already?😂
Thanks. Yes. He is majoring in math in computer science in college right now.
I watched one of your other videos and hoy said that you can't change the Bob to sealed because the tube is larger? Does that mean I can't do this??
+ItZ Joshy you can if you buy the right size bottom bracket. It is probably American size. Here is a sizing chart. www.danscomp.com/serve/products%7Ccharts/bearingchart.htm
Okay thanks bud :)
thank you just what i needed
You're welcome.
***** if u have a spare wheel u can also use an axle
hello, so my bike has a one pice crank the exact one is “175mm Cromo 1-piece, 44 teeth”, is that an american size crank?
Yes
Were can l get the3 pics in Johannesburg
6 thumbs down?!? a**holes, GREAT WORK HOOHOOHOBLIN. love the vids im subscribed!
Thanks! No matter what you do in the world, there are at least 6 people out there who will hate it.
I believe the sleeve in the middle is more than just a dirt cove, it also provides a stop for the inner bearing races, so that when the crank bolts are torqued you don't put a side load against the bearings. Thanks for a nice crisp How-To. also "shut up Jimmy " has been added to the things I yell at the shop. haha.
Thanks. You're right about the sleeve. Jimmy hasn't shut up yet!
Morgan Oliff )
i know this is old and probably wont get a response but ill try.
i have a Sunday 2019 blueprint complete bmx and it has 8 spline 3 piece cranks but an unsealed spindle and crankset i already know that i need to get sealed spindle when i get sealed bearing but will i need to upgrade my crank or should they work with an 8 spline spindle?
I think you can get an eight spline spindle for it. You’d have to check with the bike shop to make sure, but because it is a brand new bike, they probably use the same cranks on their sealed bearing versions.
hoohoohoblin thanks i just asked my bike shop if they would work and they said yeah they would, nice to know i dont need new cranks cause my sunday cranks are pretty good cause there 3peice 170mm and full chromo
This vid is very helpful. I have a newer kink curb with a unsealed American bottom bracket. The look of a sealed bb is awsome. Looking to get rid of the big nut and replace with the cone washers. So much cleaner looking.
It's an easy job to do, and the sealed unit works great, without ever needing adjustment.
its a very good video expect you never put the shins on your drive side, that should always line up with the rear driver, there always for non drive side
Thank you for helping me in 2020😁
You’re welcome
Sir can you please tell me where I can get that USA seal bearings bottom bracket to buy, I really want to change out mines.
canniggia morgan This is the one we bought: www.danscomp.com/products-PARTS/455021/American_3-pc_Sealed_BB.html
What size of Spindle do i need? I'm going to buy american bottom brackets.
I don’t have the bike anymore, but I think it was a 19 mm spindle. The most important thing is to make sure you buy a spindle that is the same diameter as the inside diameter of the bearings.
Any homemade tool to pop out the cups EVENLY, so powder coat doesn't get chipped? Park tool BBT90 on a budget?
Not sure how would be the best way to do that. Maybe put a flat short piece of wood through the hole, then turn it sideways inside against the edges, and pound it out with a stick or socket extension.
shut up jimmy XD
😂😂😂😂😂
I'm thinking of doing this may I please know about how much it costs
+Chandler Harrison Check the video description for part names and brands. Bottom bracket is around $20 and cranks are around $70 and a sprocket is $25.
om thank you for restoring my sanity. i had a whole load of problems when buying a new axle for my 19mm Spanish bottom bracket and now after watching this i can sleep at night :D
+AFOMEDIA You're welcome.
SHUT UP JIMMY😂😂💀broo best part in the video‼️💯💀😂😂
Haha! Thanks! I’ll tell Jimmy.
Get rid of those piss take to change 1 piece crank sets lol 😂
lol xD "Ohh sugar"
hey I have a bike like yours a 1 piece crank. But Dans Comp don't have the item number in stock..... So im looking for a American bottom bracket but I cant seem to find one...... But will a American mid work????
It depends on what size bottom bracket your frame was meant to use. Here is a link showing the different sizes with pictures. @serve/faq/bb_diagram.htm
Ok cool man thx
Mantapp
Que medida de rodamientos son ??
19mm
Excellent video! How long did you use it? Did it fail sometime?
It worked until my son got tired of the bike and wanted to buy a stronger lighter frame. I’m sure the bearings are still fine right now.
Man, I was looking how to tight that kind of axle correctly. And you instead replaced it.
Is that a sapient BMX bike? I have the same one!
It's a Mirraco Debut bike.
Ok man, I just found my old Scorpion Breakdancer BMX in my Dad's garage and I am not up to speed on all the sizes of parts especially the BB.....but from your video I know I have exactly the same set up, retaining cups, 'loose bearings etc. Can anyone give me the correct measurements or links so I can buy some new parts to bring my old BMX back to life??!!!
TIA all!!!!
Cool vid! I have a question. Can these crankarms be used with a chainring used on a regular one piece crank? And what about an offset chainring? I am asking because I am considering upgrading the drivetrain on my Felt cruiser. :)
You might be able to drill holes in the chain ring if you could get it off the old crank. But it would be better to just buy a new chain ring with the new cranks. Sometimes it just makes more sense to buy a whole new bike, as these parts can get expensive.
@@hoohoohoblin I guess I wasn't quite clear. My Felt cruiser (tank frame) has originally one piece crank. It also has offset rear sprocket and an offset chainring, because I run a 3" wide tire. So I want to know if I can still use the offset chainring if I switch to 3 piece cranks.
Been wanting to replace my old haro cranks with new ones and this helped sooooo much! Thank you
You're welcome.
Hey p0 🐞
The "little tube"is a sparser to keep your bearing from creeping inward
Now my bros bike wont look jank
BMX Radio Evol 2012 www.playbike.ro/produs.php?id_produs=10185 fit because I just bought bb 19 mm spacer and simple without that did not fit?
where did u buy the sealed bearings
Panda BMX 1975 is the only one in the world that had screw in bearing cups on their one piece crank with quarter inch automotive ball bearing, Let everybody
Very helpful, thanks for posting...
And,uh... SHUT UP JIMMY!
Thanks. I will pass that message along to Jimmy.
If you need to replace bearings in a sealed American bottom bracket kit for a 3 piece crank it takes mid bottom bracket bearings
Have u played WACONZY - ‘NA GOD’ Music video ?
If no, kindly watch
it Here>
buy mp3 - #christainMusic
Exact crankset I am installing right now! Those cups I actually thought were part of frame and kept me confused for weeks! Very helpful vid! Thanks!
You're welcome. I thought those were part of the frame, or welded or pressed in place when I first did this as well. I wish bike parts came with instructions. I'm glad I could help.
Maybe i should pay you to build my bmx bike when i get a new one 😂😂
What is a USA loose ball is that mid or American
I think it's American
Alot of people don't want to tell you how to upgrade ..They want you to buy a Bmx that cost more than my car. SHUT UP JIMMY...
lol that was she said
I found the same crank set on Dan's Comp but I could only find a Mid BB. Would that fit to replace my American BB?
Best bottom bracket conversion video on TH-cam. Seriously. No1 else went thru the process as good as that.
+Albeezy6 Thanks!
"SHUT UP JIMMY!!!" 😂😂😂😂😂
wow
i went to a bike shop cuz i didnt know how to take 1 pc cranks off and they told me you cant take them off
Hoohoohoblin , while removing my press fitted cups on the loose ball BB i dug into the frame a bit using a flathead. Do you think ill have any problems
My sprocket has a spacer built into it. Do you have to have an additional spacer of any kind between the sprocket and the euro bb? Clearance is fine and chain in straight.
I need an answer, if your frame is american bb should i use also a american bb?
What if you were doing this to a mountain bike or something? Do they have the complete kits for that? 2x 0r 3x?
Hey how much did this cost you?
I'm Zoid The bottom bracket kit was around $20. A good set of cranks can cost anywhere from $70 on up.
This video is a life saver ive been searching the galaxy for sealed bottom brackets and all i need is 19 mm thank you so much man
+Christopher Walker You're welcome.
First of all I would like to tell you that this video helped me out tremendously. It still was a ball buster but without this video I would have been twisting in the wind. So, again I thank you 💯
You’re welcome.
Thanks man that really helped me ... You are awesome ... Keep up the good work.
You’re welcome.
Yeah Jimmy!
What MM size is the allen wrench for the end bolt? I have a 6 but is too small. Must be a 7 or 8.
+sirbrad4 we made this video along time ago, and we don’t have the bike anymore, but I think it is an 8 mm.
I am trying to change my bearings on my Sunday 2018 blueprint. It has the same cup things in the B.B. do I need this special American bearing or am I good using a 19 mm bearing or 22
+Nikolas Iwankiw Take a look at this website. It will show the different sizes of bottom brackets, so you can see which one you need. Most likely you need an American bottom bracket conversion kit. www.danscomp.com/tech-help/types-of-bottom-brackets/
The Sunday blueprint comes with seal bb bearings
Ima save this video so informative on how to do this
hello im kinda new to BMX im having the same problem im going from 1 piece cranks too 2 piece cranks would I need to change the sealed bearing bottom bracket???
Cape Flims Yes, you would need to install an American Sized sealed bearing kit. We bought this one for $19.99. www.danscomp.com/products-PARTS/456061/Mechanik_BB_Kit.html
Thought I had to get a screwdriver in there to get the cranks off! But forgot to take the peddle off first 😂😂
Shut up jimmy lol
time to upgrade my mid school 1 piece gt interceptor to a 3 piece.
vid was on point
thanks
Thanks! Will run to HD and buy the bolt and washers was not sure how to install my new bb cups. Will also be using the bolt for headset installation as well.
You’re welcome
I turn my bearing cone clockwise like 8 times it keeps getting stuck please can someone help me out
what is the crank called? sunday crank or somthing?
They're Sunday saker cranks

So any 19 mm conversation kit will work with any American style bottom bracket?
I think so
i recently switched from the old school ball bearings and ordered a redline american 22mm bb, the center tube will slide over the spindle but, the spindle is threaded and will not slide through the sealed cartridges...any suggestions? its an old school DK General Lee with an iron cross 3-piece, 1995-99 model i believe, are some spindles just not compatible for a bb?
I think you need to buy a new axle, built for sealed bearings. Probably new cranks too, but maybe not,
that tube that you call the little tube is called a spacer
I'm using 1 too with about 52-4 teeth sized sprocket... so I cant effort 2 or 3... Is there a way to use small sprocket like 24 or any without changing cranks or making it ugly??.
The sprocket can be changed. I made a video showing how it fits on. th-cam.com/video/ZF8RF-eD9-k/w-d-xo.html
My first bmx bike was American unsealed bb. Over and over the bearings would fall apart and usually end in the cranks locking up and tossing me over the bars. Finally i wised up and bought a bike with mid sealed. I don't know why i never got this kit. It would have saved me some headaches.
+Billy Celli I had the same troubles with bottom brackets, and I was kind of surprised to find that someone actually made a conversion kit.
Thanks bro! Totally Awesome!
You’re welcome.
I found this funny cause I have the same crank and pedals accept my pedals are red
What size wrench is needed for the first bolt you took off with your hands
Do a day at the skate park video
That's a good idea. The kids haven't been to the skate park since we built a half pipe in the back yard. We should go back there and shoot some video now that they have some skills.
How do I keep the little tube thing inside the bb straight when I tap the cups in
i have a unsealed three piece crank set but i don't think i have that washer the goes on the sprocket do i need that to make my bottom bracket sealed? or does the washer that is on my set up now work?
Dylan Nolan that was just a spacer you don't really need it
Dylan Nolan it goes in the sprocket making the inner diameter smaller if not there the sprocket would flop up down as you pedal
I have an old diamondback bmx bike from like 10 years ago , it has lots of upgrades such as tires , hubs ,bearings , chain , pedals and stem , it also has a 1 piece crank with unsealed bearings. Would it be a good idea to do this or just keep running the stock crank
Not sure. It may be worth more money as a collector's item with the stock crankset. If it works fine, I'd leave it alone.
