Hi,

This isn't the normal question about the cartridge bearing size, but the balls!

The phb515 and 700 bearings on my hub are worn enough that the cone adjuster/preload is full in and I get play.

My hub's had heavy use for over a decade, so no complaints from my side.

Getting the cartridges replaced is silly money.
You can get a new hub for the cost!

I do hate profiteering on spares.

Fortunately the cartridges can be rebuilt.

The balls are now down to 3.14mm.

I neglected to measure them when new!

The closest standard sizes are 1/8", 3.5mm and 5/32".

The 1/8" is too close, so I don't think that's the one taking into account wear/play.

Does anyone know the original ball size, or have a newish hub they could measure?

Thanks

There is significant play, which could not be accounted for with such a small ball reduction.

I'm guessing you are suggesting that the wear is on the races then?

That leaves me pretty much in the same situation though....

I've now got extra worn races.... How big a ball to squeeze in to take up the gap =)

It's more of a shot in the dark now though.

Why not ask CK?

3.5 and 5/32 are both way to large to fit.
It's clearly a 1/8" ball with worn races.

I've spaced the back of the small bearing.
This has moved the cone adjuster back in to range.

I've had it confirmed that this is an '08.

So I've abused a CK hub for over a decade and so far all its needed is a couple of plastic spacers made from my Ardrock name plate.

These hubs are great value!
