It took me a while because I had a few problems to sonve, but finally all 4 window lift motors are done.
First, here is a stock configuration. Good to see what the base problem is on this motors.
I used POM-C, which is a special thermoplast used on heavy duty industrial rollers, gears or guides etc.
I bought a 12mm stick of it on Ebay for under 2 bucks. The bummer was, that it actually was 12,6mm and would not fit. So I mounted it to my column drill and sanded it down to 12mm (+- 0.2mm). Voila, perfect fit.
Nice, durable and easy solution to fix the broken Puks in the Front Window Lift Motors.
The two quarter window motors had different drives. So this part was easy.
Of course, I had to make my own gaskets again, but these were simle to make with a circle cutting tool.
The rest was just cleaning, polishing, a little bit paint for the housings and a lot of grease removal.
