XS650 alternator rotor puller.
Rather than wait 3 or 4 days and pay $18 for an alternator rotor puller (yes, I'm a jew) I made a puller myself. The rotor has a threaded spigot on the outer, the thread being M24 x .1, actual outer size of the thread being 23.8 mm. Being as the thread is .1mm that makes the core diameter 22.8.
Using a 25mm length of 27mm pipe I skimmed the inside out to 22.8mm the thread core diameter and I skimmed the first 3mm out to 23.8mm as a thread depth reference, that being the actual thread diameter.
Once the thread was cut, I faced off the opposite end of the pipe and welded on a fine thread 12mm nut. For the pusher bolt, I faced the end and skimmed off the first 5mm of thread. This providing a nice flat surface for the rotor centre bolt to rotate on.
The thread on the spigot is extremely rough so these sizes gave a nice tight thread fit. Once screwed in place with the aid of a spanner so as not to risk stripping the spigot thread I screwed in the pusher bolt and the rotor came off with a minimum of effort, certainly easier than I thought it was going to be.
Bonus: It only took about 30 minutes to construct, I saved $18 and got the rotor off now, rather than in four days time.

No matter the cost it's always a better feeling making it yourself

Hi 4Me,
Nice work ! It is very satisfying when you make something like that to do a simple job. Since the tool is unlikely to get a lot of use the $18 is better in your pocket.Best Regards:

I don't mean to be picky, but I suspect that the thread was M24 x 1mm rather than M24 x .1 as mentioned in the original post. 0.1mm pitch would be extremely fine and shallow, and the maths for the recess in the tube for thread depth work out for 1mm pitch but not for 0.1mm.
I used to be an engineer, I'm not an engineer any more, but on the really good days I can remember when I was.

Absolutely correct. The phantom stopper put his stop there. I'll get up him forthwith.
