Anybody know for sure whether the early vdub wiper motor has the transmission built into it? I need a small motor/trans with an output shaft that "wig-wags" instead of rotates.
I've actually looked at those and thought they'd be too big to fit my space. Here's a pic of where the stock motor went, up inside the cowl with the actuator arm towards the rear. I've had my dash mocked in and there's less than 4" from the rear of the dash to the flat where the arms meet up. I've got the arms temporarily screwed to the (ww) motor opening. For an idea of scale, there's prolly 3" between those two screws...
I ended up with a waterproof 2-speed, fully adjustable marine wiper motor, made by Ongaro-Schmitt. A little more than I wanted to pay, but it will fit into my cowl and not get damaged by rain...
I don't believe they would have, as they were designed for a single 12" blade. This one is also designed for a single blade, but 24" so it will likely work. It's all fabbed up and in place, fits like a glove. Only (hard) work needed was making an adapter from the shaft to the pivot arm. Had to make it from a 1/4" steel brake nut, spent prolly an hour filing it into a "DD" oval. The factory adapter was brass and wouldn't weld...
I had a similar problem with space and found that there were several rear window motors that would work in a small space. You would have to be somewhat mechanical to work out the linkage but if space is an issue, they would work. Someone else mentioned the Ongaro marine units. I ended up using one for my truck since I wanted two speed and self park. Instead of a hidden linkage to the second wiper, I went with a stainless linkage on the outside and the effect is cool for my hot rod International Harvester pickup. The motor, inside the overhead cowl, drives the left side and the right side is just a matching pivot to hole the wiper arm. I only had a little over three inches in the cowl for the motor. https://www.youtube.com/watch?v=AilT1Q1tN10

I don't see how one could build a wig-wag linkage around a constant rotation motor. Since the arm points would need to be 180° apart, they would foul each other during rotation...
The drawing you referenced in post #13 shows the wiper blade posts have some kind of transmissions attached to them. Mine do not, they are straight-through posts that only transmit the motion they receive from the arms. Think about two arms 180° apart trying to rotate in a constant direction, they will make one-half a turn before running into each other...
Here is what I *think* you're getting at, but it requires moving the motor offsite and adding an additional link bar. Your method would require more work than what I'd want to do. Besides, the Ongaro has a left/right park selector that you can swap plus an adjustable (65° - 110°) sweep angle...
Sorry about getting all pi$$y, I'm an old man and sometimes have trouble seeing what others consider obvious. BTW, I use the same old CorelDraw (v9) that I've had since the late 90's. Another symptom of age, don't want to "upgrade" and have to relearn everything...
