Default Re: REbuild Early Vacuum Wiper

The best source of info on these wiper motors are the original patents. The one you want for the 'original' motor style is patent # 1,840,233. This shows the internal parts and describes the operation of the motor. I am attaching the patent in PDF format. Hope it helps you.
