Currently taking apart one of my engines. Got the rear iron and rear rotor housing off but for some reason, the E-shaft is not budging at all since I need to lift the E-shaft a bit to remove the intermediate iron.

I put back the flywheel and tried turning it by hand but it won't move at all. Tried hitting the front end of the E-shaft with a rubber mallet. Won't turn and won't go up or down.

What else can I do? And what is causing this? Before I could turn it as well but it is still pretty tough compared to my other engines.

 

Did you take everything off the front?
front cover
oil pump sprocket
front counterweight
thrust bearings

Yup, took off everything.

 

Spun/locked bearing on front rotor or front stat gear? That's usually what I see on engines like this.

Have you tried taking the remaining part off the engine stand (i assume it is on one now) and sitting on the floor, and see if the front iron can be pursuaded off the shaft? Cores are easier to take apart on the floor, than the stand, because you dont have to try and lift the e-shaft and int housing at the same time...the rear comes off rearward on the floor, and the front comes off frontward.

One time I actually had to mount a e-shaft/front iron onto a hydraulic press to seperate them. I was able to get the rotorhousing off the iron's surface by a few mm, enough to get some metal plate in between there, to serve as the press foundation. I had to rig up a "landing pad" for the int. housing, rotorhousing, rotor and e-shaft once it seperated. Obviously the shaft and front iron will probably be toast, and possibly more as well.

 

Its actually on the floor right now since I removed it off the stand (putting a different engine on the stand.) I tried hittng the front iron but it still won't come off. I'm going to try using a pry bar later on the front iron or remove the front stationary gear with the pry bar.

Hmm...I just remembered something. When I was removing the thrust bearings/washer, I noticed a few very small bits of broken metal around that part of the E-shaft.

But I think you're right. The bearing seems to be fused/locked on the E-shaft. Thanks a bunch for your help!
