Hi, 

 

I've taken off some hubs off a mini to recondition. The part number on them is BTA186 which took me by surprise as checking the Minispares website prior to having them off I thought they'd be a FAM part number. 

 

Going by the Minispares description "THE original BTA186 with chamfered end is 72MM in external width where the bearing sits but FAM2391 with step on end is 75MM wide to stop bearings flexing with bigger wheels. (THIS WAS ROVERS THEORY)"

 

 

Does anyone know if there was any advantage of the later type with the larger 3mm width? Lastly, what should I be looking out for when looking to assess hubs before reconditioning? Should I buy new on the safe side? As these are going on a mini with a conversion that will have a lot more power going through it than it originally did!

 

Cheers

Also DSN classics website says that late model of disc hub has a habit of "spinning' the wheel bearings".  

 

Is this due to the larger width?!

IIRC the early ones would not fit the 8.4" disc set up unless more material was removed. while the later ones would fit any disc set up. We always went for the S type when running 10s .

All hubs are prone to having the bearings spin in them and that's the 'trap' with used hubs.

 

I've found the later hubs also have a change in King Pin Inclination from the earlier types.

 

I don't find the cost of new hubs objectionable at all. That's the way I always go these days.
