Thread: window motor current consumption + more

i'm speaking about this one:

it has some plastic plug (white round thing covering a blind hole) and some screw (bottom right) - what are they for? what sort of grease is preferable for this unit?

My experience with Disco 1 windows.

If a plastic wheel in the scissor lift breaks then the scissor may jam. If you then try to raise or lower the window using the motor you risk chewing out the centre of the rubber damper inside the motor. You hear whirring noise but no window action. If scissor jammed, but rubber damper not yet broken then maybe high current flow?

Without the motor, scissor lift in good condition, the window should drop like a guillotine.

Old rubber weather strips can hold glass, but you would hear rubbing noise as you move glass.

I didn't hear any rubbing noise - just the usual noise of motor, my problem is the window is moving very slow - sometimes I have to help it with my hands (and it's working more hard when moving upwards).

here's what was inside the motor. just some small stains of rust on the shaft in this place (see my finger):

the threaded plug is used to shift the shaft along its axis (i don't know what for) and may be to add some oil.
it's clean and dry inside the magnets:

(the small plastic caps are probably designed to fill in oil to lubricate the bushing of the shaft?
the brushes also seem to be in good shape:

do not know what are these holes made for? (they are from the outside right into the redactor case, without any plugs (the upper two holes):

here's one of these holes from the inside of the case:

still, the main question is what sort of grease is best for these purposes?

What vehicle and year? For example slight changes in early disco 1 and late disco 1 window winders.

It could be lack of lube in motor, bent scissor lift, broken wheel in scissor lift, chewed out centre in rubber damper but in a cycle partially engaging then slipping. Just hope it is simply grease in motor.

If ball bearing race then oil? If bronze bush then bearing grease?

Can't really help you much beyond this. Let us know if greasing the motor works.

added a drop of machine oil to the bushings, the current draw increased to 3A ;-)
probably, I have to wash off all the grease from the worm thread on the metal shaft and may be from that plastic gear inside the casing and reapply a new silicone-based grease.
it might be so that the play in bushings also played some role…

it's and old style classic with hinges on the front doors.
when putting back the motor, I'll try to add some wd40 on the scissors' rails and may be some grease along the slots of the window (what sort of grease there?)
as the window's behavior definitely differs from the one of the guillotine
