Dude - I've rebuilt my forks 4 times. You don't need the tool, or at least I didn't.
Ok, but then how do you stop the cartridge tube from spinning, when doing the allen bolt up?
Fair question. Thing is, I'm not entirely sure it's even necessary to have the tool.
I know I must sound like I'm talking bollocks, but I've done this four times now, it's just not an issue. If it was spinning, you certainly couldn't torque them up correctly either, but I am talking about a bike that's done 149600 miles, 4 trips up the Alps and passed 14 MOTs with not even an advisory, so I must have done something right! I can't imagine I've just got lucky....
For getting them undone, an impact driver is very handy, by the way. You don't even need a clutch puller to take the flywheel off an engine with one of those. Brrrrr, click, and it's off... simple.
Edit: I probably am talking bollocks.Did I just use a spanner... I honestly can't remember...
