Vacuum wiper motor Just asking if any one has had good success rebuilding the vacuum wiper motor like whats on my 35 coupe. Or am I better off replacing it with a 12v motor. Thanks in advance, Paul

Re: Vacuum wiper motor I "rebuilt" mine without any parts. Just took it apart, figured out why it wasn't working right, fixed it, cleaned it, lubricated it (with distributor cam grease - nothing else) and it works fine. Give it a try. You might get lucky like I did. Be sure to test it hooked up to vacuum sitting on the fender before re-installing it to make sure you've really fixed it.

Re: Vacuum wiper motor In many cases, an old vacuum wiper can be fixed with a little brake fluid (some use ATF) . What happens a lot of the time is that the "paddle" inside dries out and the brake fluid or ATF makes the paddle swell again to provide the seal needed. If still on the car, this can be done by pouring a little brake fluid in a bottle or can, inserting the vacuum hose going to the motor into the fluid and manually working the wiper blade back and forth about 6 -8 times. This should suck up the fluid into the wiper motor. Let sit overnight and then test it. Remember to put a rag under the motor (inside) to catch anything that may leak. Car may smoke some at first start up, but it will clear up. Do it again if needed.

Re: Vacuum wiper motor Thanks everyone, this gives me some options. Paul

Re: Vacuum wiper motor I did the same on my 33 as Old Henry did, just took it apart, freed it up, greased it and put it back together. It seems to be working ok.

Re: Vacuum wiper motor Thanks Mart, I took mine apart also but my gasket did not hold togather. So I have to at least replace that, I see Macs has them. Thanks

Re: Vacuum wiper motor When you test it on the car wet the w/shield to simulate rainy conditions as the wipers work easier when wet. Pete/Ct

Re: Vacuum wiper motor They say, around my auto shop, that brake fluid can be bad for paint. Be careful there.

Re: Vacuum wiper motor On my 46, I disconnected the main hose from the motor and squirted sseveral drops of 3 & 1 oil. It's been working great so far.

Re: Vacuum wiper motor Quote:
My '39 1-1/2 ton flatbed has the vacuum wiper motor. I removed it and, next time I started up the truck, heard quite a bit of vacuum noise going on at the open end of the hose so clearly THAT end works. I sucked up some ATF by working the mechanism - some suck and some blow = a bit messy. But can someone give me an idea how easily the motor should operate? Should it operate with little effort or should it take some push & pull to operate? Also, I do need the wiper arm and a blade - any sources for those? |
Re: Vacuum wiper motor I think I would get an eye dropper or hypodermic needle and put ATF in the wiper before trying to check it out. Let is sit overnight at least. This will lube it up and soften the paddle. It shouldn't take a LOT of effort to get it to moving, but as everything gets a good coating of ATF it should work with very little effort.
Most any of your vintage parts dealers should have an arm and blade. I know, at least on 35-36 pickups the wiper arm should be black. Not chrome. |
Re: Vacuum wiper motor Thanks, Lawson.....that's what I needed to know; level of effort for proper operation.
(Already knew about the tomato but that's a good reminder, too!) |
Re: Vacuum wiper motor I squirted some WD40 in my '34 roadster wiper motor some 8 or 10 years ago. The motor has been working fine ever since. At the time the wipers would only go from the park position to full left and then stop. Someone suggested this on the earlier version of this site.
