I have a little John deere 6k generator that binds when I try to turn it over. It has a yanmar diesel motor. Anyway, I'm trying to pull the stator off of the crankshaft so I can separate the case halves. But I can't get the stator off of the output shaft. I assume the output shaft (crankshaft splines) and the stator shaft are simply joined by a spline collar, but the stator simply won't budge. Anyone familiar with how the stator is typically joined to the output shaft? This is as far as I have gotten.  I tried using a slide hammer on the other end of the stator, but I only succeeded in partially removing the bearing on that end. | ||

The piece attached to the crankshaft is the rotor. Most generators have tapered crankshafts with rotors press fit. You will need a long bolt like tool, or a rod and bolt to push the rotor off the crankshaft.  | ||

These old fellers have a vast well of knowledge....give them a try. http://www.smokstak.com/forum/forumdisplay.php?s=b 1d7b31f82fdeb6c8ea2827efd4d7979&f=6 http://listerengine.com/smf/index.php?PHPSESSID=7f bnlnv9o36n2dmga1kuh2ptc1&board=15.0 | ||

Model number on the engine? | ||
| Torquehd |
Thanks for the help guys. I'll post my findings when I can get back to work on this project. Model number is LV100. From what I've read online, these are good little motors. The crank turns over almost twice before binding, which tells me the binding has something to do with the cam, as I know that (for 4 stroke engines) the camshaft rotates at half the crank speed. | ||

What's the model number of the complete genset? Being a Deere, I might be able to dig up more info. | ||

I'm not sure what I'm looking at, but most alternators used in this type of gen set has only one rotor bearing at the rear. The crankshaft itself acts as the front bearing. To facilitate this, a flexplate is bolted to the flywheel, often with spacer rings to position the rotor within the alternator case length wise. The flexplate will have a female spline at its center, into which the drive splined drive shaft of the rotor fits. If the spline is stuck, try removing the perimeter flexplate bolts. Once the rotor shaft is removed, a puller can be used to remove the flexplate from the shaft spline. | ||

I have to ask the dumb question: "are you sure it's not just on the compression stroke?" we're talking 22:1 ratio here. See the decompression lever on the top? | ||

If you PM me the model number I can pull up the tech manuals for it. Judging by Griffmeister's location and comments, he'll have access to the same info as me.  | ||

Also, before splitting the case, I'd probably start with the rocker cover and head to make sure it's not something like a broken valve spring binding up | ||
| Torquehd |
Thanks for the vid, bandm. Yes, I flipped the decompression lever. And removed the rocker cover. And removed the head. Still binds. Hopefully i'll get back to work on it this weekend. I'm assuming it's damage to the cam drive. We'll see. I have about 2 months before I have to move across country, I'm hoping to have this thing up and running by then, so I can use it to power my travel trailer. | ||

Where ya headed? What size trailer? I'm thinking about full timing it myself! | ||

PCS'ing back to Ft Bragg from the PNW... I love NC, just not the Bragg area. But, I've got to go do my time there. Again. My trailer is a 28' with no slideouts. My inlaws bought a brand new 36' trailer with 4 slideouts, and sold their old trailer to me for 1/3 of what it should have cost, so I couldn't really say no. It's nothing fancy but I really like it, there's something about having your own house that you can take anywhere. And I keep it stocked up so I can bug out in it if I ever had to. I still refuse to call sleeping in a trailer "camping". "Camping" involves a sleeping bag, a tarp, and boiled creek water that tastes like campfire. | ||

Sounds great  Let us know what you find in that little engine. I have the chinese knockoff version. Hasn't blown up on me yet. If it does, I will probably pony up and get the real thing. |
