Rear Wiper Gear Repair

Hi all....thought you might like to hear how a friend of mine fixed my rear wiper on my 87. The
motor worked, but a gear was stripped and the motor just went through its cycle and nothing
moved. We took apart the motor assembly and saw that the big nylon gear was stripped on the
inner hole, so the rod that is inserted into it was not grabbing anything and no wipers. My
friend drilled out the middle of the nylon gear to fit a nut....then used a hand file to file down
each side into a six sided shape that would fit snug with the nut. The nut was then pressed
onto the rod on top of the small teeth.....it presses well and is very strong. The nut was placed
into its freshly cut home with a little glue on it to secure the fit for a long time. Re-assemble the
unit...line up the female part that moves the wiper arm and you have a wiper that works great
and will not slip under load.

My friend was the mastermind behind the job......and a great idea it was. The Porsche dealership
said they do not sell the nylon gear separately and that I would have to order the whole
assembly at some crazy cost...can't remember it now. So this alternative is much cheaper (a bolt
and time is all that is required) and much stronger.

Hope this solves somebody's problem....Dan Becker '87 black/black , 5 speed
