Taking the plate and some 200 grit sandpaper rolled into a tube (emery cloth or a Dremel with a sanding drum will work, depending on how much you need to take off the plate), sand/polish the bearing surface of the plate until the gear is free to move when placed back into position. Sand/polish evenly to maintain an even circumference.

Why is my windscreen wiper on my 85 740 wobbling?

The Haynes manual showed a picture of a cable adjusting nut with no explanation. Removed the entire assembly and found the nut under the left side shaft.
What to do if your wiper motor is broken?
Also take a look at the wiper switches at the very bottom of the case to make sure nothing is broken or bent. If you wish at this point and if all the small gears are clean and where they should be, you can apply 12 volts to make sure that the motor works.
