You are correct the pins are shot. Brass sleeves are a good idea?

Re: Aermotor A702 head/gearbox removal


Are you going to use the mill to pump water or for pleasure ?

Good question. Pleasure. However, I would like the wheel to turn. Don't need push rod to go up and down, as I'll not use it to pump water. That brings up more questions:
1. Do all the gears need to be installed in order to lubricate ...

Note in this picture on the casting where the drive shaft slips into the casting, and the hub slips over the casting, it is all wallered out pretty bad. Is this something that can be repaired? Or do you think the casting itself is junk? I guess I could try and weld up the ...

Re: Aermotor head/gearbox removal

IMG_20250214_165326.jpg This windmill has a few issues. It ran a long time without oil. Even with heat I was unable to get either of the drive gears loose so I had to cut the drive gears off and also cut the shaft off next to each drive gear in order to get the hub off.

In the picture above, is ...

Re: Some eye candy

See that one sign in the background says fertilizer. I didn't think they were fertilizing back then but I must have been wrong.

Once I remove the Nut, umbrella washer and pump rod, is there anything else, other than rust, holding the shaft into the gearbox?

Re: Aermotor head/gearbox removal

Thanks CTXmiller. I see the nut you're talking about. Need to borrow an open end wrench big enough to fit the nut. Looks like a 1-7/16. My 15" crescent dosen't open wide enough and my 18" is too big (tight quarters in there) to turn the nut.

Aermotor A702 head/gearbox removal

Attached is a picture of my Aermotor gearbox that has an 8-ft fan/wheel. I'm trying to determine how to disconnect the shaft that goes to the tower from the gearbox. Does the shaft unscrew from the gearbox at the point in the picture where I wrote an arrow? If not how does it get removed. I have ...
