Hi, I just got a mid 80s Centurion Pro Tour 15, and it has Suzue Sealed hubs, and I can't figure out how to adjust them (if they are adjustable). Here is a bit more info on the hubs: https://www.sheldonbrown.com/centurio...s/20specs.html

When I take the nuts off, instead of a dustcap there's a sealed thing which is black. I'm guessing this may be a cartridge, but isn't there some way to adjust them sometimes?

I had Suzue "Sealed Mechanism" hubs supplied OEM on an '85 Bridgestone 400. These were just ordinary cup-and-cone loose bearing hubs with a plastic seal to ****** water and dirt incursions. They adjusted like any other loose bearing hub and were not cartridge bearing hubs.

I've got an '83 Centurion Pro Tour myself, and it has Suntour cartridge bearing hubs, they've got a sticker that says "sealed bearing hubs" on them. I've had them apart, and they are indeed cartridge bearings. I had an '85 Centurion Accordo at one time, and it had Suzue hubs with a sticker that said "sealed bearings." But the hubs on the Accordo were cup and cone hubs. So "sealed bearings" can mean different things. However, I'd bet the Suzue "sealed bearing" hubs on your Pro Tour use cartridge bearings. Check this thread out that I started some time ago regarding this. If you read through the thread you'll get some great info on cartridge bearing hubs and towards the end there's a poster who states they have Suzue "sealed bearing" hubs that use cartridge bearings-

Sealed Bearings and Sealed Mechanism (which my hubs were labeled) are not the same thing so if your hubs truly say sealed bearings then they are cartridge bearings. Mine weren't

My experience with cup and cone tells me this is not cup and cone since the second of the two nuts that lock together is the cone, but in this case it's a seemingly useless set of things that must only hold the cartridge in solid.

Also, if this is cartridge, what is the proper procedure for tightening the nuts together? With the nuts off, the unit is pretty well in place, but there's play, so I assume I have to use the innermost nuts to remove the play and then tighten the outer nuts against them, but how tight do I need to make the inner ones?

Do not attempt to remove the play in a sealed bearing. Clamping it in the bike should be sufficient. ALL Q/R hubs should have play when out of the bike. Even if some minimal play remains it will not cause the probs that occur with a conventional cone and cup bearing.
