Window open & close Gear Box

[gpscotty]

I have a 1984 Avion 30p, the gear box does not move the window it does turn in both directions. Do I need to find a replacement or has any one repaired one. I could not find a part number or name, it uses a knob rather than a crank to open & close the window and is riveted to the frame. Any help would be appreciated. gps Thanks in advance

These operators have a splined shaft that both the knob and crank will fit. I had knobs where a crank handle would stick out too much.
My OEM operators/gearbox) were also riveted, as were all the joints. I drilled them out and used small stove bolts and self-locking (nylock) nuts during re-assembly.

It is fixed. after getting it off and opened up, found that the gear was rotating on the shaft. J B Weld did the trick, you have to be very careful getting it just were you want it, a Drummal was used to remove & polish after letting it dry.
