Dakota Boy, thanks for your comment. If you don't understand my explanation, that tells me others probably don't either. Please, let me know what you need clarification on. Sometimes I assume too much. If you notice, the only ones who responded were members who already rebuilt their motors. They speak from past experience, which leaves the novice somewhat in the dark.

Ford window motors are not typical 2-wire motors. They are quite different in their construction and operation. What part should I clarify? - Dave

Yes...the bushings are cinder bronze with oil. But there would be no effective way of getting oil back into them. I used a light "green" grease. Just enough to assemble. I turned .004" off the commutator and finished with 400 paper. I think it is most important to clean between the segments. They were packed full. Packed like that will not allow a good contact between the commutator and the brush's. Resulting in a slow turning, torqueless motor. JMO

Dave, from memory (based on my last power-window problem!!) the window motors seemed to only have three wires,- one for up, one for down and an earth.

I guess I need to read up on electric motor theory and then just take one apart. It's all that strange terminology that's leaving me in the dust!

My window motors could be described as above: "slow and torqueless". I bet all they need is a good cleaning inside?

Before going to the trouble of disassembly and risking breaking anything, consider drilling a hole in the rear housing, on center. Small spout oilers, or pin oilers, are available or even use a toothpick to get a drop of oil on the shaft and bushing. Often this rear bushing gets dry or gummed up and the shaft won't spin easily. Since the motors are in an enclosed space the hole could be left open or you can seal the hole with what ever, epoxy, silicone, caulk, or seam sealer. If it didn't help, you can always take it apart. It saved a couple of heater fan motors and a seat motor for me.

I was going by the wires at the plug nearest to the motor, the one you have to unplug when taking the electric motor out.

The '66 shop-manual shows three wires at the plug,- yellow, red and grey (looked black on my car!)

The short answer is, you're both right. As I said, Ford motors are not like most DC motors. They have different fields and are wired differently. Today's motors only have two wires because the fields are permanent magnet.

I will explain DC Motors (and Ford DC motors) in a different thread. It will take me a while to draw it out, so give me some time. - Dave

I put a few pages together and made a PDF file about DC Motors.

Please read through it and let me know what you think:
