Shimano DX crank owners, have a ? for you..

[MSMXII]

who's running a set of OS Shimano DX's with a sealed bottom bracket? I'm going to be running a set on my new build and want to convert the looseball and cone they came with to a setup that uses sealed cartridge bearings. American BB or eur coversion, It doesn't matter to me,  as long as I can use the stock DX spindle.

Any help/info would be greatl appreciated...thx guys

they all came with loose ball as far as i'm aware, and due to the unique axle i dont think they have ever been made.....

Exactly what Sam said above I'dve thought 

The Sugino CV BB ( same as HLT cranks) are a threaded axle sealed bearing BB O/S set  ,, but do not have the all important splined edge to carry the spider for a DX crank set up 

As they say round here

" I think tha's puncin' up brew "

or you're gonna really really struggle 

Why is it so important for them to be sealedbb any anyway

If the BB is fitted and greased correctly it would be fine   

,,if you're thinking about using in competition (racing)half seriously ,, sell the DX and get Redline 401's with the Techmatic sealed BB

I suppose you could modify/ruin the axle by machining the threads of to a certain diameter to install cups with sealed bearigs cartridges , but that would be   

So not impossible

One option could be to use the standard bottom bracket, well greased, and use the outer plastic guards from a modern semi-sealed bottom bracket kit eg:

Correct you are sir  They all came from the factory with a sealed mechanism cone and loosebal, but I'm looking to upgrade due to the fact that I live on the ocean and looseball systems take a beating quick.

 I don't want the hassle and maintenence the looseball and cage bearing offers you, plus I like to ride and usually end up beating the looseball setups to pieces rather quickly.

Thanks for chiming in, I see you really dug deep and found this post as well  This is how I found the site... I was browsing the net and ran across this very same post.

This is exactly what I'm wanting to do since I'm sure it MUST use sealed bearings of some sort. I did contact the memebr that owns that P.K. and all he was able to tell me was that the BB was a Kajita branded unit.

It seems that whatever BB it is it allowed use of the original spindle  Now if I could only figure out what model # it is and where to source one, I would be set    PLEASE HELP!!...Mr P.K. Ripper man

this I'll have to check into. Maybe it will allow the use of the stock DX spindle? Depending on if it's 24 or 28tpi and if it accepts a 5/8" axle. If so then it's a possibility 

Thanks for the help/idea, much appreciated,

Right on my friend for the welcome...very     I usually spend all my time over at the Museum and live under the same name. I found this place while browsing for an answer to my question.  

I've had more members and people willing to help here then anywhere else, seems like a very "RAD" place to visit...thanks for all the input so far all

Basically, in it's stock form that's what the DX cranks came with. They are a cone and loosebal setup and they have these cool plastic cones that slip over the cup edges and somewhat seal the bearings from the elements.

Ideally I just want to have a total sealed cartridge bearing setup for lack of maintenance and better performance. If I find a setup that uses cartridge's then I can use full ceramics or Hybrids, huge difference in performance and smoothness compared to a OS ball and cage.

Well it was a longshot but I figured I would at least ask first. Looks like it's time to have a custom spindle made

I also have an question....

ever seen one like these...

Shimano DX cranks , with Motobecane written on it... Its a two speed ....dubble blade 
i did find it last weekend . It came from a new OS Motobecane ...and it was never used. They changed the Motobecane  to single speed ..

[MSMXII]

Nice score  You don't see too many of those re-branded DX's  http://bmxmuseum.com/bikes/motobecane/34835

think so..but this is a two speed crank. The one on the link is one speed.

Very rare any way... 

[hunterdubber]

That Motobecane was marketed over here as the Yamaha BYZ  , same build spec too

Bought some new Shimano DX crank decals from Dell
