power window motor bushings and brushes

These pictures are great. I really appreciate the share of your trick to hold the contacts in place. Great job!

my driverside motor looked much smaller as did the replacement for my 91 mgm. i still have to fix my passenger side motor in which i was gonna use the motor that came out of the drivers side because it was only the neoprene plugs that were bad in that on. my worry is it dosnt look like i can remove the motor from the gearhead. i didnt study it real good at the time i just threw it in the box to be done at a later date. does anyone know if these motors can be disassembled from the gearhead?

look at the first post in this thread. It shows the thing completely disassembled.

i did look but like i said my motors look slightly different it looks like this...

but on this image it looks like the motor seperates ill have to look at mine better when wife gets home.

for that one, it looks like it's got screws that hold the casing of the motor to the gearbox. should just be 2 screws and out everything should come. remove the plastic gear first of course.

yeah but i remember when i looked at it briefly i remember saying to myself "fuck its sealed!" ill look later though.

Here is a picture of the smaller flat one

One screw holds the gear cover on those.

hmm... I wonder if it's one of those "bent tabs at the top" kind that doesn't actually have any screws holding it together.

Now I am confused...What exactly are we talking about? Splitting the entire motor in two or just removing the cover for the gears, bushings etc?

[HATNINJA]

ok she just got home i went out grabbed it out of the trunk and it does have screws. i hate old age its fuckin with my memory! it is identical to the pic ringting posted.

Bunch of pics of thin motors. I am worried this is hijacking the gentleman's post, thread, whatever you kids call this stuff. OHHHH Good news I learned I have a microsoft paint, look out world.

I don't mind more pics and info at all! These are all things that are good. I don't mind corrections and criticism either, I'm no genius
Those newer ones look like the brushes are trickier to get back in place... Another technique that works well is two "L" shaped picks and an extra hand or two. I reckon one could use their feet if they had good prehensile toes.

Moisture won't help that's for sure. Are the gaskets in the motor still intact? If they're missing or torn, it will be more susceptible to moisture problems.

Well I definitely tried to re-use a gasket on the end cap, it made it even more a pain in the ass and I remember feeling like it was a waste of time anyway. I guess there would be a gasket on the other end of the shell too... I didn't even pay attention to that end
I did notice this time that there are little notches that seem like they need to line up on re-assembly, and that the magnets in the shell aren't right in the middle so there is a right and wrong way to put it back. (they should fully overlap the action end of the gyro thingy, right???)
I didn't notice these things when i did one in the 85 back in 2005... it still worked up until a week ago when the new bushings crumbled... only got 5 years out if bushings in a passenger window??? c'moooonnnn!!!!!!

I might gut a died-after-a-year re-manufactured one I have for parts. What bits out of them to you use when you rebuild yours??

Honest to god I have done this with my feet. I think you just won best post of the month award for the twist tie picture. That's fuckin genius.

The green arrows point at the brushes, these make electrical contact to the rotating part of the motor and are designed to wear out. Once they wear out enough they can slip out of place and get covered in their own crud, leaving a poor connection. These aren't too bad, but I replaced them with some better ones I had.

Harvesting tip: you can pull just the end caps and attached brushes through the speaker hole with the door panel still on... the passenger side is *usually* better off than the drivers side. save the springs if you can, they are easy to loose and crucial.

Hose everything off with electrical cleaner, and polish the copper contacts on the electro-end of the motor (red) with some fine sandpaper.



Twist-ties are one method to ease re-assembly. This is another test of patience, since the strong magnet will want to pull the motor out of the end cap, letting the brushes spring back out of place. try to re-use the thin gaskets if you can salvage them. Some silicone might work well in its place (to keep moisture out)

Where did you buy the brushes at? Mine wore out in the bronco and found this thread via google. Hoping they are only a few dollars so I don't have to drive to the JY and pull a brush housing.
