Just picture a circle ie the rotary drive gear inside the wiper motor box and then a pin located at the outer circumference and one half way to the centre of the gear.
For each rotation the pin closer to the centre will not push and pull on a crank as far, which when this motion is translated to the wiper wheel box to which the wipers are attached, you get less rotary effect or a different degree of wiper arm sweep.
So if you set the pin at the right distance from the centre line you will get 130 degrees of sweep which is about what you need.
I had to drill out the pin on my gear, re-position and spot weld to get the amount of sweep I was chasing. Not so uncommon a thing for this crowd though.
