Hi there all,
I've got really **** hubs on my MTB - I mean bog standard, simple hubs - fitted as standard on my
Trek 4300... Now - as I've done with most of the bits of my bike - I thought I'd give them a service
- disassemble, clean bearings, grease, reassemble...
All has gone very well - all the bearings seems to be intact and undamaged, after I degreased them.
Now - I might need to explain how I took them apart, and what parts it consists of in case thats
important. Basically, I held the drive side locknut with one spanner, and unscrewed the non-drive
side one. So the drive-side assembly has not moved at all, and shouldnt need touching...
The locknut is a flattish hex nut with indentations on both flat faces. Then came a flat washer,
which fit snuggly into a rubber 'seal' which no doubt keeps all the **** out. Then under all that,
there is the nut with a tapered side which rolls against the bearings. Is this the 'cone'? Anyway -
I'll assume it is for now...
So I unscrewed the cone, and took it off - then pulled the axle through, took all the bearing out,
and cleaned it all nicely... Then came the reassembly.
OK first - greased the inside if the hub where the bearing sit (the cups??) with a thin line of
grease. This allowed me to stick the bearings - 10 per side) to the grease to stop them moving
around. Once they were all in - I greased on top of them and put the axle back through. When I
screwed on the non-drive side cone, what I did (as I say - I don't know if this is correct or not),
is to tighten is up until resistance is felt against the bearings - then loosen it a tiny tiny bit -
the wheel runs really smoothly, and there is no play at all in the axle... Cool - all going well so
far. Now comes the annoying bit. no - I put on the rubber seal, and the washer - and tighten up the
locknut - but the wheel then locks up - what must be happening is that the motion of turning the
locknut is turning the washer - then turning the cone too - so it locks up against the bearings !!
What can I do to stop the cone from moving from its position I set it to?
Cheers all - sorry for the long winded post
