a. 36 mm spacer -  :thumb:   You'll probably have to make the spacer from a bolt that fits on the hole - cut the head off.

b. a M19 screw   - M19x1 bolt, about 5" long, judging from what I can see in the video. There is no harm in getting a 6" bolt, just to be on the safe side.

The alternator rotor ? we use a motorcycle axle bolt and a sliding hammer. It may be 17mm - but try threading it in and making sure its all in nice for a few threads to be sure.
Cool.

hi and good day dear Buddah

first of all : many any thanks for the reply. That is very cool. If i got you ritght: then you use the axle - bold: in other words - you are using the axle-bold ofthe GS 500 as a screw that fits into the rotor!?


i love to hear more ... plz respond.

i look forward

regards

That's not a sliding hammer. Its going to push it off by that inner bolt bearing against the crank - I don't know if the crank there is hollow or solid. Or how far it is down in there - I don't remember. I have only used an axle and a big weight that the axle goes through and you essentially hit the bolt away from the engine and it comes out.
Cool.

While I'm pretty sure that Buddha's method works, I think that other methods will also work; like with the puller (long bolt and spacer) in the video that you posted.

So, I think that the part (abzieher = puller) in the picture will actually work, but you will also need the 36mm spacer. I can't tell you the diameter. You will have to see what size fits.

There are many ways to do this. Been awhile since I did it but this is what I remember:

One way is the bolt/spacer method:
The bolt to remove it is M14 x 1.5
The spacer is 36mm long
Use a strap wrench or jam the gears to prevent the rotor from spinning while you crank the bolt.
This is the method I used.

Another way is the improvised hammer method:
Put a large washer on the end of the GS rear axel bolt and then a weight that fits around the axle then you can thread it into the hole where the crank bolt was, and you have a homemade puller tool:
                              |
==========[w]=|D
                              |

the "=" is the axle bolt. Left side threads into rotor.
|D is the hex head end of the axel bolt.
the [w] is the weight that slides up the axle
the | is a large washer the you can slam the weight against to pop the rotor off.

hello dear all  - good day dear buddah,good day dear SK Racing and Bluesmudge,

first of all : many thanks for all the hints and tipps..

at  the moment i have a tool that seems to do it.  All i do is to muse how to do the setup - in other words how to set the toll

- should it pull only the rotor
- should / could i include even more "stuff"!?


what to do to center the whole stuff - perhaps i take a scew like  shown in the picture - the one on the right side... to center the tool

what do you say!?

That 3 jaw puller is one tool that you should not use on the GS style rotor.
I can even see how the one you posted earlier may work. But the 3 jaw is guaranteed to fcuk up the gear you're using it to bite onto.

Find an axle man Maybe the GS'es front axle will work. Then a washer and a barbell weight will do it.
You're hell bent on everything else. Walk into a junkyard and you'd get hit with 20 of those - if not for the fcuking quarantine - I'll have dragged out 20 by now.

Cool.
Buddha.

the rear fork axle is usable there, cut a 36mm long bolt and put it inside the rotor and tighten the  axle, rotor should pop out easily this way, the thickness of the bolt must be thicker than the original fastening bolt, so it doesnt fuk up the threads
also, use impact wrench if available
