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.
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.
