How to Remove a Generator Armature and Stator

okay so better engine all broken down and this engine is garbage but the powerhead is good so I want to get this off if I can so I can put it on a new engine so the first step was removing these long bolts that go on outside here like that so there are four of those two on the top two on the bottom and then there are also four shorter bolts which went through this housing as well so once those are out theoretically the stators free to pull off the one catches this bearing in the housing here is tough to get out if you're lucky you can pull this housing out by hand but usually that's not the case so I have a puller setup I'm going to apply some pressure you have to be careful not to apply too much because you will break this end housing it's just a thin aluminum and it can't take too much pressure also i unbolted that housing from this frame rail so it is completely disconnected and should well allow it to come off so I did try this the other night and I was not getting very far and I was afraid I was gonna you know push this too hard so I did put a little lubricant over by the bearing where it meets the housing and I'm gonna try it again and see if it will come out this time okay good now this stator should slide right out in it's heavy so make sure you fold it well that's it so this is the easy one okay so that came off pretty easy actually as it should fun part will be getting this off they almost never come off easily so I will do some prep and turn you back on for this all right so today I'm going to be taking this rotor off this tapered shaft you know to do this you have to obviously remove the stator first which exposes the rotor and going down the center of the rotor is this bolt and it's threaded at the end and that threads into the tapered shaft so once that bolt is removed you need to inspect right at the collar here and see if you have threads sometimes you get lucky and those threads there in my case there were no threads so I had to tap it and I was able to forget it about three-quarters of an inch down so I bought the appropriate sized bolt that matches these threads now and I marked how far this boat goes in so it's about three quarters of an inch and then the next thing to do is to get a rod and stick it down the shaft all the way until it hits the tapered shaft and then mark where the rod is coming out so the rods all the way in just going to mark it and the idea behind this is you want to cut the rod a little bit short so it actually when you put the cut piece in it should go past the end here and go in at least a quarter of an inch probably more you want to have enough threads so that when this bolt starts pushing there's enough threads and it's not going to tear out and you want to have at least a quarter inch of threads left to push that rod into the tapered shaft popping this off so I want to cut this rod to size and then crank down on this and see if we can't get this off all right so the rods been cut down to size so it just goes in like that okay and for this I put a moving blanket under here these things do tend to launch off so I want to try to give it something soft to land on and to loosen it I'm gonna use a breaker bar it's not a huge one but it is probably about a 2 foot bar so that helped give me some leverage this engine as you can probably see by the hole is no good otherwise I would have stuffed rope down the cylinder to keep it still for now I have it kind of Jerry rigged with something kind of holding the flywheel I'm not sure how well that's going to hold but uh I guess I'll give it a shot there it is so that is how you remove a rotor this method I've had the best luck with you know you do have to have some patience to tap this out properly and make sure you get a proper sized rod I've done this before with a a threaded rod and that actually went into the thread a little bit here and I kind of messed the thread up just a little bit so when you get a rod you do want to try to get one that's not threaded and one that'll sit you know outside so that doesn't go in that thread hole so I hope this helps someone and thanks for watching
