Here's two places I've bought them before, but you're right - both are out of stock at the moment - sorry!info on the clutch spare part is fantasic - thank you very much.
Seems to be that google is letting me down on finding anywhere that has them in stock - anyone able to point me in the direction and/or of a search strategy that's going to help!
Yep, takes a few mins.So to tighten the clutch slightly in a zee is it as simple as tightening the little bolt under the clutch cover?
Tighten it to the point just before it breaks :thumb:How much? Half a turn? I don't want to overdo it....
Knuckles is my illegitimate son :tsk:Lol. You and Moorey are brothers aren't you....
So that's why you keep calling me a bastard! Gee thanks dad.Knuckles is my illegitimate son :tsk:
No lad, it's why I keep calling you a cunt.So that's why you keep calling me a bastard! Gee thanks dad.
I suggest tighten it only 1/4 to 1/3 a turn at a time.How much? Half a turn? I don't want to overdo it....
Cheers - glad I wasn't going mad and they're actually out of stock.Here's two places I've bought them before, but you're right - both are out of stock at the moment - sorry!

Not really surprising as there's a lot of these failing and people are starting to just replace the cam unit themselves rather than bother sending the whole thing back for warranty.
Have you tried asking your LBS to order one through the Australian Shimano distributor? Or are they out of stock also...
If you really want to know how much to tighten it, use a torque wrench in the centre of the drum to measure the actual friction being exerted by the clutch. See Shimano diagram below but substitute torque wrench with a 4mm hex bit for the allen key. Then adjust, check, repeat until you get within the torque specs for your model of RD...I turned the bolt in further almost 3/4 of a turn and really haven't noticed a lot of increased tension/resistance? ! Thoughts? I've left it at that by the way..

If tightening that bolt still doesn't increase the tension then it might be that your cam unit has already failed - and no amount of tightening will work. Check the cam bracket - here's what it looks like when they fail...
