A customer asked me to replace the brushes and turn the armature on his '89 Grand Wagoneer rear window motor. The motor looks and runs amazing. The brushes were a unique size, but no issue. I decided to degrease, clean, and regrease the main gear. I noticed some slop between the metal "transmission" and the plastic gear. So, I separated them. Bit's of grease and shattered material fell out and scattered on my bench.
Does anyone know the size, shape, and material of these buffers? There are several other window motor gears available for sale with a similar set up, but I really don't want my customer's rear window to break because I misunderstood something.
Any help would be great. I called one reseller today, and they would not share with me on how they tackle this particular problem.
By the way, I believe the material is called delrin, as it's a hard plastic but it has some give, and will reform after a time.
