From memory the odo on my SD was a bit different than this. I just removed the screws that held the plastic cover/cap on at the end of the gear housing, replace the gears and put everything back together. It still works well.
I need to repair this SE odo so I can use it in the diesel conversion if I want to have an accurate speedometer/odo. It appear that the small circuit board is hard fastened to the clear plastic cover.
Does desoldering this board appear to be the proper way to replace those gears?
