Iv been all over the web trying to find a rebuild kit for my 1940 Chevy 1/2 ton truck vacuum windshield motor. Iv contacted Wiperman and he said he does not work on that type of motor. Its a 1 inch wide bowel. Is there anyone else that can help on this. Iv got the flapper soaking in brake fluid right now hoping it will soften some. The fiber washer that the spring connects to is broken at the spring contact. I'm trying to glue that back together. Be so much better if I could find the right parts to put it back together with.
Ficken in New York used to advertise regularly in Hemmings, they did a good job rebuilding vacuum wiper motors. Are they still around ?
Will you might try posting a question on the Vintage Chevrolet Club of America's tec forum. Good chance someone there has the needed info.
You will have to sign up but it's looks to be a good place. I have used it when working on vintage Chevrolet's.
Until you can get that wiper motor rebuilt, get a electrical motor conversion from
once you get used to steady wiper speeds and not having the blade stop when you accelerate, you might not go back!
Fickens rebuilt my Model A wiper motor and it is amazing. Been playing with old cars for 40 years and never had a vacuum motor run so well!

The Wiperman is Mr Ficken, He told me he doesn’t work on my type of wiper motor.
I got the motor working. Between the brake fluid soak and gluing that fiber washer it seems to be working great. Im going to take it apart again and coat the barrel with a light coat of grease.
