Hope everyone is having a good day. I just spent the afternoon disassembling my power drivers seat. What an ordeal!
Once I got the passenger side rail off the mechanism, I couldn't get it to move at all. I hit it a few times with a 16-oz hammer in both directons with a very big swing and it would move about a thirty-second of an inch. I ended up using a 10-ton hydraulic press to push it out. It required several setups in the press to clear all the protruding bits as the slide moved.
When I finally got it out about 2 hours later, the inside of the track was severely rusted. Because I couldn't get to the rear bolt when removing the seat because the seat was covering the bolt and wouldn't move, I had to pry the bottom part of the track out of the way in order to get a socket on the nut. Of course the nut was supposed to come off, but instead the entire stud came out...the nut never moved.
So I've got the track soaking in evap-o-rust at the moment. I'll have to straighten it when the rust is gone. But, for some reason took off the motors from the gearbox. I'm sure I could have reassembled it with much difficulty and aggrivation, that was until I dropped one of the motor cans and broke the magnet. Great, now I have to remove another seat for parts. Hopefully the donor will be in better shape than the original and I can use that mechanism!
I do hear people talking about removing all that old grease and replacing it with fresh. Are these fold talking about the grease in the slides? If so, my slides are dry as in no grease whatsoever. I'm hoping that the suggestions don't refer to disassembling the gearbox and replacing that grease. That would involve drilling out rivets and looking for alternate fasteners for reassembly. Please tell me this isn't the grease folk are referring to....
I guess I now know way more than I ever wanted to concerning MN12 power seats!
