My passenger door window regulator is old and worn out. How do I know this you ask. The window winder handle will sometimes rotate a little without the window going up or down. I can hear and feel that the gears are slipping out. As time goes on, the gears would not engage consistently and the window travel would stop or even drop a little. Bummer, time to figure out if this is something I can fix.
These parts, the gears, were not, are not available separately. You'd have to buy the entire window regulator. And that part is listed in the Moss catalog under...unobtainium.
Has anyone opened up a window regulator and tried to repair it? It is riveted together you know. Well that's not going to stop me, I have a drill and a rivet gun. In case anyone wants to know what it looks like in there, here's some photos.
The teeth of the small gear were getting shaved at the top edge and the ends were getting rounded (photo attached) by the larger gear teeth. The larger gear was sliding to the top end of the small gear because the bent tab on the case, which keeps the large gear in place, was pushed up a little. Most likely because something was under stress from not being aligned properly, forcing the large gear to arc up, press against the tab, and over time slowly started bending the tab up. That play let the large gear slide up to the ends of the small gears teeth, which started and continued the wear process on the edges of the small gears teeth. Plus the pressure the large gear was putting on the small gear affected the housing area of the shaft that held the small gear. That area got enlarged letting the shaft have just enough play as to let the small gear tilt enough to let the large gear slide up the edges of the small gear's teeth. Clear as mud?
I bent the tab back down, and filed the small gear cluster thinner, so that the top ends of the small gear teeth were now less rounded. The amount I filed down, I replaced with a washer of the same thickness. I placed the washer under the small gear to press it to the top of the plate, where the large gear makes contact. Now the teeth on both gears align better and the housing tab which is now pressed back where it should be, keeps the larger gear from arcing up. I also made an insert to go around the top of the shaft to stop it from having any play. It's a big improvement, no skipping gears and rolls up and down like it should... almost like new. How about that.
Cheers,
Roger
