First numpty Pro II question
I am starting my first strip down of a Pro II rear hub. It’s about 5 years old and hasn’t been apart before (ahem).
How the ‘eck do you get the freehub off?! The Hope video shows a nice clean one and he says “twist it and it just pulls apart”. Yeah. Right.
I am twisting in the freewheel direction and pulling away but it’s not having it.
Sacrifice 6 virgins round a bonfire while chanting a Led Zep song backwards or is there a simpler technique here that I’m missing?Posted 5 years agoNorthwindSubscriber
If the wheel has a tyre on…
If the end cap is still on, spray some silicon lube onto it (helps to unstick the o-ring)
If it’s already off, apply a little penetrating oil to the axle/bearing meeting point
Attach a bit of cassette to the freehub (not the whole thing, just a big cog/cogs- to get a grip on)
Put wheel on blocks of wood, supported by the tyre
Stand on tyre over blocks of wood.
Crouch down and grip the bit of cassette (might want to wear gloves)
Lift while gently rocking back and forth
(don’t overdo it, a really strong squatter could probably destroy the wheel with the sideloading!)

A couple if 2p’s between the axle/freehub and your cassette lockring. Gradually tighten the lockring against the 2p and the freewheel will gradually be pulled off. Remember to put a chainring on the free hub so that you can remove the lockring again. It may take a few 2p’s.Posted 5 years ago
Thanks all. Halfway there – a stack of coins eventually blew the freehub off but it has then jammed further along the axle and I can’t get the (very tight) lockring off as the whole lot is flopping around. But I have something to work on now.
The Hope video puts me in mind of the Haynes manals for cars – they always use brand new pristine models and make it look so easy, eh?!
Great 2p trick. 2 euro coins also work.Posted 5 years agoNorthwindSubscriber

Be careful with the 2p method – if is really badly seized you could strip the thread on the lockring/freehub before it shifts (I did).
+1 for that, they’re not really designed for that sort of punishment, especially if you’re only engaging a small amount of thread.Posted 5 years ago
Thanks again everyone. Rebuilt the hub now with nice new bearings, will do the freehub tomorrow.
I stripped it as the cassette was wobbling expecting to find a broken axle, but in fact the single freehub bearing had broken up and was just a horrible rusty mess.
Once I got the freehub off, it’s really not been that difficult. A great way to spend an afternoon!Posted 5 years ago
