As I see it with the new parts in my hands, the black plastic rotor bolts to the aluminum carrier with three 2.5mm hexhead bolts. The carrier itself is a press fit on the end of the cam shaft(s). So to remove the rotor, you should be able to pull the rotor and carrier together no? Mine are stuck and are not coming off even with a lot of persuasion. I cannot undo the three bolts b/c they are stripped out but that does not seem relevant.

Any ideas on how to get the rotors off? Aghhh!

Thanks,

Adam

The rotors are screwed in like you said with three 3mm Allen screws.
It is flush fit/just screw pressed.
(Get the three screws out it falls to your hand.) ;)

Under it, is the rotor bracket.
It is screwed to the cam shaft the bracket is also KEYED.

( I don't remember the screw size... ) with a 4mm or 5mm Allen screw in the CENTER.

Now the new rotors don't fit the old brackets, but I don;t think that this applies to your case.

Regards,
aam.

I've just done this job, and those small Allen bolts that hold the rotors are a challenge to remove.
I too was worried that the hex would round off, but I used a really good quality Allen key and made sure that it was inserted fully and also squarely.
I thought a few times that the Allen key would break given the bending under torque, but there was a satisfying 'crack' as the bolts gave.

There is quit a lot of thread that goes through the rotor, so if you drill off the heads, you should be able remove the remaining threaded portion with a pair of grips.
