Oh Sh*t - Now I Have To Split The Cases

Just realized that I didn't know what I was talking about. After checking my garage, came to understanding that I don't have as many shafts coming out of crankcase as 550--No chain drive! Quick look at 550 manual reveals a seal or two that mine doesn't. Since your going to expense of rebuilding, if reasonable, I would replace just for peace of mind.

Yes that 32mm nut is fun, I just used an impact gun to spin it off. Can be more fun to install trying to hold clutch basket tight. Likewise, not sure if 550 uses a couple metric allen bolts in front behind oil filter. These were particularly tough. Used a longish T wrench with short cheater to get enough torque to break it free. Word of advice, draw picture where each bolt goes and record length of bolt with diagram. It is real easy to screw up where the go.
 
How Do I Remove The Rotor

How Do I Remove The Rotor

As above. How do I remove the generator rotor from the end of the crankshaft. I have removed the bolt that holds the rotor onto the end of the crankshaft and the rotor appears to have a female thread inside it for a puller to be fitted. Is the rotor on a taper on the crankshaft? Is it on a keyway? How do I get the bloody thing off without the factory puller? HELP!!!!!!!!

The loctite actually does come labeled as the color. Blue is semi permanent (you MIGHT need to take this apart in the future) and red is permanent (This is for keeps, like a weld, never meant to come apart again). It's like gasket stuff that comes a "utra grey", "black" etc... "Blue Loctite" really is the the part name.

Permatex uses the same color coding for their products,

You don't need to remove the rotor to disassemble the engine.

Also, maybe you mentioned this earlier, but exactly which GS model are you working on? There are many important differences in the way you pull the rotor.

Brian the model is a '77 GS550B. Just pulling the motor to pieces to wash out the crankcases of grinding residue to fit 650 top end.

I was going to pull the rotor so I could fit a new crankshaft seal on the generator side when I put the cases back together.

Cheers. Don
