Thanks for input. I took one apart. What a mess. Rust rust everywhere. Water gets in at the top where the motor attaches with nowhere to go but down - Sloooooowly. If it had not been for a ton of grease in there it would have rusted away. That bottom gear was a pickle since it had rusted to the shaft. Next time I may drill a hole just below it to allow me to get a screw driver in there to pop it loose.

Bummer.... Well now you know how to do it.. Just got to keep the sequence of the spacers/shims and bearings in the proper order.

Is the jack going to be useable or toast?

Just a curiosity...how did you get the gear off? I'm happy you got to it before it was really toast. I said your going to have a time getting it off but rusted on? Wow, I guess I was lucky myself. I have mentioned many times before that if your drains are hitting the motor housing that you need to cover your motors with a plastic bag and get extended drains along with sealing the base of the motor at the square tube. Either way does it still work?
