1969 Formula S owners needs help with Variable Speed Windsheild wipers

Yea.
After looking the situation with fresh eyes.
Your's should look like my Levi's.
Not that funky 3 speed motor.
It's real easy to take apart and clean.
Should do that.
The only part that might be tricky is when you take the armature out with the worm gear on the end there is a brash thrust plug under that "adjustment screw" with a little disk of some material . Must be a "seal".
I used compressed air to blow grease out at that point.
And almost "lost" those things in the gravel.
Fortunately they both stayed in the housing.
