Window winder motor overhaul
Posted: Fri Apr 17, 2020 6:17 am
Please be gentle with me, my own stupidity!
Ok, mea culpa. I dropped it whilst cleaning up the outside, and would barely work after It was working before removal.
See photograph of the post mortem, my first time inside one of these!
The main problems are:
One permanent magnet fractured into two pieces, one of the fragments is loose.
Broken plastic pillar contacts - looks old (I think this is the wiper parking contacts, disabled in this application with a cut black wire?)
Near solid gearbox grease.
Filthy, but apparently un-worn commutator.
50% worn brushes.
Bearings seem ok with minimal wear.
Gears seem in good condition.
A few questions please.
My research tells me this is a Ford Escort Mk1 wiper motor?
I was thinking of glueing the broken magnet fragment back in place. Best glue for long life - epoxy or suggestions?
What is the best gearbox grease?
I can ignore the broken pillar contacts?
Best way to clean up the commutator?
A quick look on eBay, I didn’t identify new brushes - anyone know of a supplier for these?
Apologies for so many questions.
Malcolm.
