Subject: Re: windscreen wiper system lubrication
So yesterday evening I opened the system:
I removed the two wooden cappings. Then you can see the whole system: from the left side the speedo like drive comes into the left gear. Inside the continuous rotation (in only one direction) is transformed into the back and forth movement of the wipers by the internal gears: a worm gear to a big cogwheel moving a toothed rack. This is connected to the right side drive with just one internal cogwheel (sorry for my limitation in correct wording for all these gear parts).
The right side gear front plate can be opened by just removing 4 screws. It was very old hard grease inside, which I replaced by new.
The left side gear has to be removed from the car (2 screws) to be opened from the back side. Here grease looked better but I also cleaned and put new in.
The tacho like inner cable could not be removed easily so I have bent the cable upwards and trickled oil in.
I have put all back and it works again a bit faster. But the most important was the first gear in the wiper motor because this is rotating fastest.
