760 Window Regulator Interchangeability

[blurp]

Hi all,

The driver's window on my 1988 760 does not go to the top and never has... it gets to within about 1/4 to 1/8 of an inch and then the motor starts skipping (buh-buh-buh-buh) and it won't go any higher.

I took the door panel off and discovered that the semicircular metal gear that the motor engages has had the last 4-5 teeth stripped off.

As I doubt there is any way to repair that stripped gear I'd like to replace it but I haven't been able to find anything on eBay except the whole window regulator. I don't know of any convenient wreckers (there's an overpriced one 90 minutes away where they do the pulling) so I'm trying to find another solution.

My questions:
1. Can this gear exist separately or be removed from the rest of the regulator or is it stamped into place?
2. Can the regulator from the rear door either yield this part or the entire regulator in a swap?
3. Can the regulator (or this part) be substituted from another vehicle (the 740 seems so similar to the 760)?

Thanks,
blurp

1. No.
2. No.
3. Yes, but there may be differences. If you get a different one, make sure the motor is included.

Howdy,

I haven't seen the inside of the 760 so I can't answer your questions, but I can say don't get the Pimax replacement part. I bought this from thepartsbin.com, it said it was a fit for the 740 and the 760, and it doesn't even come close to fitting the 740. Not to mention it's manufactured in france, which after Jackass Chirac's behavior over the past two years, is good enough reason not to buy something.

I have to say I'm a little preterbed about the bakelite bracket that holds the window regulator together on my 740. Not the best piece of swedish engineering. More remeniscent of a trebant. (Isn't that what those little east german plastic cars were called?)

Anyhow, good luck.
