How To Replace 1 Piece BMX Bike Cranks With 3 Piece Cranks And Sealed Bottom Bracket

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.

[@chandlerharrison539]

I'm thinking of doing this may I please know about how much it costs

[@hoohoohoblin]

+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.

[@trevorreardon8855]

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

[@ortizc1989]

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.

Excellent video! How long did you use it? Did it fail sometime?

[@hoohoohoblin]

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.

[@MorganOliff]

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.

[@hoohoohoblin]

Thanks. You're right about the sleeve. Jimmy hasn't shut up yet!

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.

TIA all!!!!

[@betoen]

Man, I was looking how to tight that kind of axle correctly. And you instead replaced it.

[@bradfordbmx]

The "little tube"is a sparser to keep your bearing from creeping inward

Can you leave your old cranks

Ralph Fisco Not usually. If they are 3 piece, you may be able to buy a new axle that fits and use it with the old cranks.

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.

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?

[@Koyadon]

I need an answer, if your frame is american bb should i use also a american bb?

[@luigiprovencher]

What if you were doing this to a mountain bike or something? Do they have the complete kits for that? 2x 0r 3x?

[@jaymags3458]

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.

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

[@eltoro747]

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. :)

[@hoohoohoblin]

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.

[@eltoro747]

@@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.

[@POFlee]

Best bottom bracket conversion video on KZbin. Seriously. No1 else went thru the process as good as that.

[@VaderIsKing]

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!

[@hoohoohoblin]

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.

[@BerserkerNick]

If you need to replace bearings in a sealed American bottom bracket kit for a 3 piece crank it takes mid bottom bracket bearings

[@StuartOnWheels]

Thought I had to get a screwdriver in there to get the cranks off! But forgot to take the peddle off first 😂😂

There's also European size crank bearing as well

[@biggameorlivestock]

Thank you for your help hoohoohoblin.

[@hoohoohoblin]

You're welcome.

[@TheOlim01]

i cant afford 2 or 3 piece cranks. will one piece cranks do fine, what are the cons?

[@hoohoohoblin]

One piece cranks are strong enough and work well. You may have to tighten up the bearings every once in a while, but they've been making bikes this way for 100 years, so it is reliable technology. If the sprocket is big, and you drop into skateboard ramps, the big sprocket might get caught on the edge.

[@TheOlim01]

okay ty

[@beanjaxson99]

Before I got my 3 pc on my bike, I badly bent 2 sets of 1 pc cranks. I also ride really hard though

[@TheOlim01]

Oh thx im getting the 3 piece cranks anyway now

[@beanjaxson99]

***** no, not harder. But if you hit big stuff, and are hard on your bike, they will bend

[@clevelandcavaliers8619]

that tube that you call the little tube is called a spacer

[@hectoralexander985]

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 💯

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

[@hoohoohoblin]

+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

[@martincruz-gz8rz]

Hey the 3 pice cranks the tube in the middle can go to any side

[@BryantSupply]

Will this work as well? www.danscomp.com/products-PARTS/456007/Profile_BMX_BB_Kit.html ...for converting american to 3 piece

[@hoohoohoblin]

It should work. Just make sure you choose the right size option when you buy it.

[@billieyklepto7514]

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?

[@hoohoohoblin]

I think you need to buy a new axle, built for sealed bearings. Probably new cranks too, but maybe not,

[@jrk3029]

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??.

[@hoohoohoblin]

The sprocket can be changed. I made a video showing how it fits on. kzbin.info/www/bejne/kHebg3ljmqlsY80

[@theduckalolis4108]

This method also works with 3 piece cranks that have sealed bottom brackets

[@hoohoohoblin]

Yes.

[@iambilly610]

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.

[@hoohoohoblin]

+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.

[@CapeFilms]

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???

[@hoohoohoblin]

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

[@tomodaniels7208]

That is right on!! I got a YST coming. & I wlll be heading to Lowes or Home Depot soon!! Thanks Very mucn!!

[@hoohoohoblin]

[@whitehorse609]

my bb is threaded is it possible to install the bearings?

[@matthewabt2545]

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

[@hoohoohoblin]

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.

[@joseplayer2144]

Did you tighten it too much cause it didn't spin very freely when you spun it. I'm just wondering cause I thought you weren't supposed to over tighten it? Do I just tighten it as much as I can?

[@hoohoohoblin]

+josepla yer21 You want to tighten it enough so it won't move from side to side, but loose enough to still spin freely.

[@Aberod155]

What size washers did you use for your dyi bb tool?

[@eightbitriddle]

you can split your cranks if you aren't careful, always dry the spindle before you attach the cranks the grease should only be applied to the middle of the spindle

[@mitchellroddan9340]

how can you even split cranks? what does that mean? I've run 8 spline cranks with grease and it works fine.

[@johnavery864]

What size washers do I get to make bearing press?

[@DadeRich720]

Aint gotta worry about a loose crank or sproket anymore
