USMC Wrangler started a thread about his vertical seat adjustment creeping down on its own. I was having the same issue and followed the thread. Smitty chimed in and suggested changing the clocking of the handle to keep our big butts [emoji33] from bumping it every time we hoist in and slide out. Genius right?
I started by popping the cover and marking the original position with a paint marker.
Note that the original resting position is about 20 degrees from level.
After removing the handle I carefully mounted it in a vise while using a socket to push the spur wheel and a second socket to support the plastic. IMPORTANT - the spur wheel had the handle molded around it! It will take an uncomfortable amount of effort to press it out! Support the surrounding plastic with a socket or you will risk breaking the handle!
The spur wheel has a groove about the diameter filled with sheared plastic. Clean off the flakes.
Remount the spur wheel on the seat and align the handle horizontal (shifted two teeth from original in my case).
Mount the handle assembly back in the vise and gently press the spur wheel into its new position. Again I used sockets to press against the metal spur and supported the plastic on the other side.
Reattach the handle and cover and enjoy! [emoji481]
