I came a cross a Stover M head this weekend (I think it's an M). It looks to be an 8ft or 10ft, the crank gears are 11-1/4" diameter which may be a clue. It's in pretty good shape, but won't turn.

I built a stand to adapt it to my 3 legged Rigid Plumber's stand, which worked pretty well with disassembly of my 10ft S model. In any case, I'm tearing it apart piece by piece, I got the crank gears and their short shaft, loose and removed. I got the internally splined pinion gears to rock in their bearing bore, so they are no longer frozen in their bearing, but...

The mainshaft is stuck.

I removed cover 23, which was roll pinned 25, bolted w/studs, nuts, 24) to splined shaft 19. This decoupled the hub 18 from the mainshaft 19.

With penetrating oil PB Blaster and an 8ft cheater pipe that I welded tabs to, I was able to work the hub and it's frozen bearings, free. Disconnecting it from the mainshaft helped.

I now have the mainshaft isolated from the hub, but it's good and stuck.

I removed the grub screw and 2" wrench-size nut, the bearings turn, but the hub and bearings are stuck on the nose 20.

What's my next move?

That does not look like any Stover Mod M that I have.

Just don't get in a hurry. That's always a good step to remember.

Maybe post some pictures? I'm not sure what that is.

Kind of looks like an Airflow. Photos would help.

Edit*
The more I look, the diagram looks like an Airflow. I have a few photos of my AirFlow disassembled with the shaft/hub removed.

Great! Nice discovery!

Yes, that looks like the drive cover and shaft I'm working with.

My job keeps getting in the way of my hobbies... I'll get some pictures up later this evening.

Boy do I know how that is....

After finishing up then selling my teardrop camping trailer, I'm finally back on the windmill.

I made a 'puller' of sorts, from a piece of 3/4" steel plate, I think it was an ear I cut off a truck bumper years ago... Anyhow, I was able to carefully pull the hub and bearings, separating it from the main body.

No cast iron was injured in the making of this film LOL

more pics so you all can see what I'm working with, and for ID purposes

more pics

backside of the hub and lined brake shoes. It's a Timken bearing model.

Haha! Got bored with the M, so you switched to the AirFlow. LOL
