If you plan on replacing the window motor or end up having to in the future, don't plan on the tech article being a big help. I just replaced mine today and tried going off the tech article and about the best it served was to give me an idea of how the regulator is riveted to the door. In fact if you go off the article step by step you may end up breaking the regulator!!! One simple step that can be performed and the whole assemble slides right out the door with little effort. There's no need to force and bend it to pull it out as stated in the tech article. For those of you who have already performed this job you may know what I'm talking about.

Theres a track that is bolted to the inside of the door which the window slides up and down in. Three bolts hold it in place. Mark the location prior to removal with a marker or spray paint so as to relocate them back in the proper location. Remove the bolts and slide the track up and out of the way. From there on out removal of the regulator is easy.

 

well i also used the tech article to change my window motor.
but only used it as a reference! i used other info also..

Great article Vader! Where do you get the brushes?

 

...The Department of the Navy.

Actually, any motor repair/rewinding shop should have a selection of brushes, as well as some well-stocked electronics or electrical supply stores, auto parts stores, or at worst, Helwig Carbon in Milwaukee can get/make/customize anything you need in brushes. If I recall, I've found alternator brushes that are pretty close to the correct size, but I can't remember what type. GM alternator brushes don't have teh spring shoulder, and would require removal of the pigtail and a lot of sanding to fit. You should be able to find the correct fit brushes since they are a relatively common size.


Hint for those with access:

Take a look at the turret azimuth drive on the old M-60s. The motor has huge brushes, but the resolver (on old D.C./pre-encoder types) brushes are about perfect. The elevation drive might be the same, but I'm not so sure.

SSHHH! (Don't tell them I told you so.)

Besides, you'll get in less trouble finding them elsewhere.
