Adjust windshield wiper speed

[Stoneage]

Hello.

I just got cleaned my wiper motors, and wonder about this numbers on it, and the little screw on the top.

Can i adjust the speed of the wipers with one of that things? And if it is possible, how?
That would be really great, because i got only two speeds! The first one is like every minute two times wiping, the second one like wiping three times in one second!

Greetings

Is there any kind of timing mark on the metal casting in the area of those numbers?

Perhaps the screw is the positional indictor. The numbers on the creme colored cover sure do look like adjustment numbers.


If you feel adventurous, mark the current position, loosen the two nuts a little, turn the cap on way ot the other and RETIGHTEN the nuts. See what effect it has on the wiper function. If it is not right, try the other way. Return it to the original position if it does not work at all.

I believe the numbers on the plastic cover are refrences for adjusting park position.

Ah, could be. I remove the wiper blade and set it back on one or two cogs in the direction desired to adjust the resting point.

that is not a adjustable motor. it will only be 2 speeds as thats how its wired. you can replace it with a adjustable but you will have to replace the switch and wiring too

With the little screw on the top i can adjust the speed a little bit, but not so like i wanted to, but it's ok.

The wiper switch is at the panel in the left of my seat, is it possible to change the turn signal switch to a switch with a wiper control integrated?

This is my actual turn signal switch:

Is some other switch fit to that one from these dealer, it's one of the dealer who sends to germany.

Wiper speed is generally a function of voltage and amperage to the wiper motor, also controllable by what is usually called a pulse control board, where delay wipers are used. I don't think there's much you can do with this setup without modifying it in a way it was probably not meant to be.

If your bus is based on an incomplete truck chassis, as many are, you might look around to see if the truck model on which your bus is based had an option for delay wipers. Could possibly be swapped to what you have, but I think it might be more trouble than it is worth. Will likely have to swap wiper motors, switch and some wiring.
