special produced to replace the weak original plastic wheel which usually loses the teeth over the years and then the rear sunblind starts to rattle and is often inoperatable. That is the large one of the 2 inside the gear. Used in all E32, E34, E31 and even E38 till 1996 for sure, even some till 1998, also some Mercedes Benz and Audi 5000 models of similar production years.

Reason:
Another problem for damages of the gear is the bush for the guide pin for the smaller gear part, when that bush get's damaged, the gear parts (small and large)touch each other too much. Since more than 1 year this bush was tested with good success together with the steel gear from me.

Repair work is of course at your own risk and ability, if the hole is not drilled very accurate, your repair attempt might not work
Price for the bush $8.00 if shipped with the toothed wheel.
Note: In Europe this drive was also used till around 08/1996 in 7 series E38, but even found sometimes in 1998 model years. Apparently the stocked items were plenty. Later the part number was changed to another design.I can only supply the toothed wheel with hex nut, NOT the one with torx, here the difference
