What do I need to service above mentioned freehub? Serviced the hub before, bearings ect but never the freehub. It's starting to engage when freewheeling. Happened a couple of winters ago and I had the lbs sort it but I'd like to have a go myself, I do all my own servicing now bar wheel truing.

Thanks!

    Hi,

    Sounds like you are in exactly the same situation as me - i managed to get water into the freehub so wanted to get it off and cleaned up re-lubed and re-fitted as ive done with a shimano in the past.

    The one I have came on a 2011 Rockhopper Comp SL and I cant find much at all about them - infact most say that it has sealed bearings which mine doesnt :?:

    so, ive got the axle and bearings off at the moment but i cant seem to get the damn freewheel off!

    i've tried a 10mm, 12mm hex and 12-point key - from either side and both seem to be coming up short... any ideas?

    thanks,

    Dan

    Oh right, you're a person having the same problem.

    On shimano - it's a 10mm allen key right into the center of the freehub, like you've tried? Other wise how does the 12mm fit in? Can you see a hex shape in there?

    I've only ever serviced a shimano and was easy as pie.

    this stout however....... looking down the axle hole it seems to be a 12-point fitment and 12mm hex isn't big enough, I'm using an old 12mm long hex key I was lent but have a newer one on order to play around with but can't say I'm holding out much hope.

    Got a selection of allen keys? Chose a 5 and 6 put them together and does it fit inside? A 8 n 4? easy way to see what size allen fittings are.

    Try a 12mm but coming in from the non drive side to get it off. That's what it's been for the last few specialized bikes I've worked on.

    Mine looked like a joytech freehub body once it's off though.

    got one on order but the crappy 12mm which i borrowed that was only just long enough didn't seem positive.

    is it clock wise from the non drive side to get it out now?

    I tried the keys together trick and definitely didn't seem like an 11mm will hopefully know a bit more when this new key turns up.

    thanks for the help so far

    Yeah clockwise to undo it from that side. I usually have the allen key held in the vice and use the wheel is leverage to remove them.

    Yes, but a bit larger, if the 11mm key is slightly small and with a 12point cut head an 11 may spin where a 7/16 may not!

    Hi all,

    thanks for your continued help on this - sending back my shiny new 12mm hex as its too large an have a 7/16" on order to try..... fingers crossed!

    your the man! just arrived in the post and it's a fit, so based on that the 11mm would - as you said - would have been just slightly smaller and a worse fit.

    just got to get the bugger off now.

    hoping that if it's as unserviceable as people say I can just stick a shimano body on the existing hub.

  • Hi,

    Did you manage to repair the freehub or did you end up replacing it?

  • id read somewhere else that it would do the trick as i couldnt seem to get the bugger open
  • Any idea where to get one, or if a Shimano free hub would be a direct replacement?

    If you're using an allen key it's actually 7/16 inch that you need. 11mm comes up a tiny bit short here. But you don't need an allen key to remove the FreeWheel hub. Try the 3/8 inch SQUARE drive extension from your socket set. It works a treat. Off in seconds.. Good luck..
