tomplum, I looked at it more closely tonight, including opening the electrical box. Seeing where the wires go is somewhat reassuring, I think I can label them sufficiently, if they have to come off. For now, they're all still connected, from the stator to the Rear Bearing Carrier, and then into the electrical box. I had enough slack to simply move the Bearing Carrier to the side, for now. However, I would welcome any tips on how to remove the rotor. I removed the long bolt, it came off easily. I had read something on another forum (http://www.broadbandreports.com/forum/r18965592-Portable-generator-disassembly-help-needed) where the person took his (different) genset to a shop. They threaded a longer bolt down through the rotor, into the crankshaft (so there was still "extra" bolt sticking out of the rotor). They then suspended it by the rotor, with the engine hanging down, and hit the bolt with a hammer, which succeeded in popping the engine off of the rotor. I tried something like that (the long bolts that hold the generator closed are the same thread, but a few inches longer), without success, so far. However, I can't hang it with the engine hanging below the rotor :) I still have the engine bolted down in the frame, but it's bolted onto the rubber mounts, so it could still briefly move away from the generator, if it wanted to. The generator is being supported from below by my car jack. I was leery of actually unbolting the engine, since the engine & generator could then slide out of the frame and fall on the floor. The stator is still installed. Any thoughts on how to loosen this would be quite welcome :) Thank you!

Yeah, um, sorry honey, I must've gotten knocked up after using one of my pills to stop my African Violet leaves from curling...but hey, look at those leaves! ...I used the urine for the pregnancy test, and what was left over I threw in the yard to keep the deer and rabbits away...errrr, the the deer. The rabbit already died. ...we're on the right track because that baby shampoo sure is going to come in handy someday with Jerry Baker's recipes. Would you like some Bourbon, honey?

Midi's are notorious for having wacky default volume settings. I avoid them if at all possible.

The lime build up would be laying in the bottom of the boiler sections, that why if it builds too much the casting at the bottom will crack. There is one other thing that can make a boiler make this noise. Depending on the size of the boiler you have to pump the right amount of water through the boiler. If your water flow has slowed down you could be flashing off steam in the hot spots in side the boiler. Some times this can happen if you have zone values and only one zone is open, you don't get enough water flow through the boiler. I would not use muriatic in that boiler. Check with the suppliers to see what they sell to remove lime in a boiler that has neoprene gaskets between the sections. later paul
