Motors are all good but white large internal gears have disintegrated. Are there spares or do I have to replace the motors too?

Window Motor Gears Available?

perhaps somebody like odometer gears could make them for us ... if there's enough of a market. anybody out at o'fest should ask them.

A long, long time ago (maybe 30 years) I inquired of someone about window gears for the wife's Bavaria, which had been specially fitted with electric windows from the factory. IIRC there was some mention of a gear from an MG that might fit, but lotsa luck confirming that, or finding one.
As above, best option would be to provide a gear (preferably intact) to an aftermarket fabricator for duplication.

I have someone who has expressed interest in making a batch of gears.
How many are we talking about?

Probably a few little drill holes around the hub will do it. I'm working with completely destroyed ones...looks like the grease ate them.
Is there a knurl on that shaft...or a flat spot? The owner has the car.

I can get the covers off to regrease them, but removing and replacing the gear looks like it would require a hydraulic press. The plastic gears get worn down from sticking window regulators.
OK. This is not going to be a simple as I had hoped. The big white plastic window gear isn't all plastic. It's a steel gear with it's own set of teeth with the white part molded on top and held in place by the steel gear's outer teeth. I'm not sure an all-plastic gear will stay on the center drive splines.
Anyone have a dead window motor so I can have the gear?
I'll ask the plastic gear guy what he thinks. Maybe there's a way, but aluminum would be best.

Early motors or late? Adding year of coupe to your signature helps, also location to your profile. Converting to e28 motors might be easier.
I do not have electric windows so don' t know size or pitch but I recall a post talking about radio controlled car pinion gears as an option for odometers. Maybe a larger one will work for the windows.http://http//www.amainhobbies.com/i...53/n/RC-Cars-Trucks-Option-Parts-Pinion-Gears

The RC gears thread was me. Since then Matthew at Garagistic has popped up and you can't beat him. Take the old odo gears out, count teeth, contact Matthew. Badda-bing.
I'm not sure plastic will do the work here on the windows. I had the equivalent gears made from aluminum a hundred years ago for the old Maseratis. No clue who made them for me.
Sorry about the location being missing. I'm in Topanga CA. This is an eccentric friend's back-from-the-dead car, so it won't be going in my sig. The car is a 73. I wasn't aware there was an old and a new window gear. I'm sure converting to newer parts would be easier but we don't have an E28 parts car and he doesn't have a visible budget. I patched his final muffler for him today.
No clue how to do the profile thing. I had a BMW shop in Marin in the 70's and worked on this stuff when it was new. I have owned well over 100 coupes, turboed them way before the 745 offered donor parts, cut one into a convertible with an electric canvas top, put 3-piece BBSs, custom sway bars and Bilsteins before anyone knew where that stuff came from, and built 30 or 40 customized (properly) cars for Hollywood folk in the '80s. I do not currently have a CS, as I'm diddling with turbo E23s and have a spiritual problem with $100K CSs and $35K Tiis. I think the coupes are great $15-20K rides and beautiful to look at, but $75-100K is pushing exotic car money and the coupes are handsome but plentiful and far from exotic under the skin.
My BMW knowledge stops in the 80s. The girls have a 94 318is and an 05 325ci convertible...and I can keep them running but that's it. Too much computer for me.
Matthew at Garagistic is examining the idea of remanufacturing the big white window lift gear. The parts from the 73 we are looking at have a steel center with a white plastic toothed ring - like a flywheel ringgear - molded on the outside.
Question: Are the older ones all-plastic also? Did they press on? Or did they have a flat place on the shaft?
