TurboGlizda Posted July 27, 2022 Share Posted July 27, 2022 Hey everyone! I recently damaged my generator rotor, so im in need of replacing it. Does anyone have experience removing the generator rotor, and how exactly do you do it? I have read the service manual, but it doesnt really go in depth. What flywheel puller did you end up using, if it wasnt the $350+ oem yamaha flywheel puller. any tips and tricks would be greatly appreciated. I've its a pain, and im scared of damaging my crank. Thank you! tried to take it off, This is what im trying to remove, for reference ^^^ Link to comment Share on other sites More sharing options...
Triple Jim Posted July 27, 2022 Share Posted July 27, 2022 (edited) I haven't needed to pull mine, but it looks like a generic puller like this would work. This isn't a recommendation, just the general idea of what I'd probably look for. Be sure what what you get is the right size for the job. This one says it's about 3" in diameter. https://www.amazon.com/AUTOKAY-Universal-Flywheel-Snowmobile-Kawasaki/dp/B0789HBP1M/ref=psdc_15690151_t1_B014VG20JM If you don't mind a little work, you could make one. I recently had to pull the harmonic balancer on my boat engine, and I used this, which I made a few decades ago, and modified for different applications: Edited July 28, 2022 by Triple Jim 1 Link to comment Share on other sites More sharing options...
AP996 Posted July 28, 2022 Share Posted July 28, 2022 This is what I made to do the job when I pulled my fly wheel and the other is the cheap tool I later bought in case I needed to do it or a similar job again. 1 Link to comment Share on other sites More sharing options...
Global Moderator mjh937 Posted July 28, 2022 Global Moderator Share Posted July 28, 2022 Some of the local auto parts stores have tools they lend. I have borrowed a spring compressor before. They put an authorization on your credit card and then remove it when you return the tool. I am not sure if a rotor puller is something that might be available, but it is worth a phone call. 1 Link to comment Share on other sites More sharing options...

So does the flywheel puller bolt go into the generator rotor hole, or does it just push on the rim of the generator rotor hole? Link to comment Share on other sites More sharing options...
Triple Jim Posted July 28, 2022 Share Posted July 28, 2022 Sometimes you can leave the rotor's center bolt in place, but backed out a little, and push on that. Otherwise you need something for the puller bolt to push against other than the crankshaft threads. 3 Link to comment Share on other sites More sharing options...

As @Triple Jim said, you need something between the puller bolt and the end of the crank. My flywheel came off without a great deal of effort.
