I'd ditch the vacuum motor for an electric conversion, anyway, if I drove in the rain much. The vacuum wipers were lame in the best of situations. Even vacuum reservoirs didn't help much.

The 50 Ford Chassis parts catalog shows the vacuum hose goes to the right side port of the ww motor an the left port is left open to the atmosphere. A cable moves the on/off valve. I am not sure where the engine side of the vacuum hose goes, but most of the cars had a port on the intake manifold for the wipers. The parts catalog does not show the ww wiper connection. The port on the carburetor was for the vacuum advance.

I have scanned and attached some info on the wiper setup that uses multiple inlets in conjunction with a valve control. Through at least '53, the vacuum wipers used both cable controls and vacuum switches. From your description, I suspect you have the latter.

Try Kent Jaquith in Oregon. His contact information is in a post about 39 wipers. Do a search on 'wiper' or '39ute' in this forum.

Hi EWATERS, I have an an old issue of SKINNED KNUCKLES that goes thru the taking apart and repair of vacuum wipers. It is a great step by step article. Tells how to get the paddles moving inside without taking it apart. It is written for a novice. If you'd like a copy e-mail your snail mail address to me.

Thanks for your insight "supereal." I am relieved to know I only need one hose. As I said in my original posting, there is partial movement and then it hangs-up. When I engage the wiper I can hear air which seems to vent from the top of the motor where there seems to be three openings with some kind of screening (or maybe accumulated debris) material. Do you know where I can send the motor for repair if I am unable to achieve full functioning?

One inlet is for vacuum, the other is open as a vent to the atmosphere. There are usually two problems with the vacuum motor: the paddle seal is hard and not holding vacuum, and/or the "flipper" valve that changes the direction of the paddle is either leaking or stuck. Sometime theflipper spring is unhooked or broken. In most cases, a faulty wiper motor is best sent to an expert who has the parts and skill to fix it. Before you do that, be sure that the linkage and wiper "tower" is free. The vacuum motors are not strong, and any binding, such as a hardened gromment, will stall it, and be sure the control cable or linkage has full travel, or the motor will always go to "park".

Thanks for the hints; I have tried lubing the pivot points and inside the stem for the hose(s). It still doesn't work. Do I need a vac. hose to each of the 2 stems with a "T" fitting to join them to the carb. vac. hose?

You can use a light machine oil to lube the paddles, the shaft that goes through the cowl and the pivot points in the drive arms. Then operate the motor without the wiper arms and blades until the motor runs smoothly. Then put on one arm and blade, keeping the glass wet with a hose to see if the motor will drive the arm. If not, repeat the procedure without the arms.
