Dura Ace AX cassette woes

[milko]

I posted about this quite some time ago but not really used the bike much so it fell from mind.

The issue is that every now and again the cassette does not engage and just spins. The AX hub had the set up where the bottom sprocket acted as the lockring, but even with the required 2 chain-whips and the LBS biggest spanner monkey on the case NOTHING.
So the question is is there a way of dealing with this without removing the cassette?

This is not a problem I have faced but could it be worn pawls?

I am hoping that its just gunked up with old grease but i guess it could be

Sounds like it could be. Whip off the cassette body pump it full of WD40 then again with liquid grease. If that don't fix it I'd look into relaxing it....

yeh but the issue is it aint coming off

Remove the axle and using a 10mm (?) Allen key remove the whole cassette body, including the cassette.

There is no 10mm allen fitting, it is a uniglide cassette on a freehub, I can remove the axle by removing the cone nut but this gets me nowhere as the freehub does not just pull off the hub body. This is the same point I got to last time I tried to fix this as you can see: http://www.retrobike.co.uk/forum/viewto ... p;t=195627

OK so things have now gone from bad to worse, this is a pic of the same style freehub as mine note the notches in the bearing race

there is a discontinued tool to remove the race which slits into the notches and unscrews it (clockwise) with the tool obviously not at my disposal I manufactured one using a piece of steel cut to the right dimensions, i then clamped it into a vice and tried to unscrew it however it has broken off the lip on both sides. I would really like to salvage this hub but this is looking less and less likely. Any idea how I can get this thing out now?

I may still have a 6spd cassette and freehub somewhere if you can wait, I will go looksee.

Cheers, but its a 7. I am gutted because these are a smashing set of wheels and I cant understand why the freehub + cassette is not just sliding off that way I could just replace the whole (freehub + cassette) thing without having to scrap the hub. Am I missing something?
