Generator rotor removal on xj700

Right now I'm taking apart the engine in my xj700. I'm going by the manual and I'm at the point where I need to take out the rotor, but when I try to turn it with the bolt the whole crankshaft moves along with it. Manual says to use a rotor holding tool but I'm not super sure what tool this exactly is. How should I go about removing this rotor. Any advice would be appreciated.

 

If you find that you need to "lock" the rotor to prevent it from turning while tightening or loosening the retainer bolt, and don’t have the special Yamaha “rotor locking tool” (which, honestly, no one has….), as an alternate solution you can put the bike in gear (preferably 5th) to lock the engine and tranny together, put the bike on the centerstand, and then slide a 2 x 4 (or something similar, but it’s preferrable that it’s something “soft” like wood)) thru the rear wheel spokes so that the ends of the 2 x 4 will eventually come to rest on the swingarm after the wheel rotates a distance…….in this way, the engine/transmission (and thus the rotor) are now locked together, and you can proceed to apply torque to the rotor bolt, which will eventually pop free (sometimes with a rather loud “bang!”) once the rear wheel locks itself in place

Or you can carefully employ this creative method of locking the rotor:

Will shifting it into 5th still work even if it is off the bike?

You would have to stop the driveshaft flange on the engine rotating. If you had a long flat bar bolted to it it should work. You are better with someone to assist you.

 

This is how I did it.
