The Stovebolt Site Forums The Shop Area Interiors Seat Adjuster disassembly

I've learned two things about these:
1. Even a rather thick monkey can disassemble them. In many cases they virtually fall apart, in fact. You may have to use a screwdriver to pry one side of the top piece out to release it, but maybe not.
2. Re-assembling them is no fun at all, but it can be done. Sorry I didn't take a bunch of images as I normally do. I made the grave mistake of greasing mine before I re-assembled it and got grease from fingertips to elbows in the process of figuring out the solution. My digital camera is so old it still uses floppy disks, but it still does a decent job and I'm trying to keep it nice. For what it is worth, the stick lube I was going to use didn't turn out to be the best choice. Too thick. I used wheel bearing grease. Seemed to be the best common ground between oil and thick goo.

When re-assembling you may see things that look like clues. Har de har har. They aren't, but sure do look look like they could be. Let me show you a couple. First and second images below, you'll see a slot in the top piece which might look like a place where you could drop in the roller after getting the thing put back together with only the cage and ball bearings. I don't know what that slot is for, but the rollers won't fit. Too wide.

Then, on the front end of the lower piece, you'll see a sloping ramp-looking part. You may (as I did) think "oh, that's nice. A clever engineer added a way to roll the cage and roller up so you can easily get it back in." You can try this like I did for half an hour or so. You may create some brand new profanity, but you won't have any success. Image 3 below.

Kevin mentioned above you have to bend up the tang on the ends of each mechanism. That's good advice and a nice starting point. Here's what else you have to do: screw a nut onto the screw on the top half, set it on a socket and smack it, knocking it out. You can replace it later, but you'll need to remove it to have any chance at all of getting these back together. Image 4 below.

From this point on it becomes sort of a complex Oriental puzzle but with a bit of patience you will figure it out and feel good for it. You may have to use a screwdriver to pry on the top piece...I did. I'm waiting on a 3/8" ball to repair my other one and if I think about it I'll try to take some images of the re-assembly procedure.
