Default Re: Wiper Vacuum Motor

I cleaned it up, so those who may wish to print it out will be able to get a clear copy. One question I have would be, what is the "proper lubricant ? (I.E. Trico approved).
I'm not real sure all that is necessary, in any event - I've driven my '37 for 20-years, in all kinds of weather, about 2,000 miles a year on average and have never lubricated the wiper motor and it continues to run fine. Seeing as how the wiper motor on my '36 is behind a header panel, I'm pretty sure I won't be taking it apart 3- or 4-times a year.

[B]Lubricating a vacuum wiper motor
(perform 3x-4x per year)

1. Remove the ]vacuum hose at the wiper motor. Lightly hold your finger over the hose nipple on the motor and cycle the wiper blade back and forth. Note that in one direction the motor sucks in air and in the opposite direction, the motor expels air through the nipple. Place the wiper blade in the position such that the motor will begin to suck air at the nipple.

2. Attach a 6” length of hose to the wiper motor and hold the open end up. Using a squeeze bottle, force one teaspoon of lubricant into the hose. Place a rag beneath the wiper motor. Hold another rag over the open end of the hose.

3. Cycle the wiper blade back & forth several times. Repeat the process again, adding a second teaspoon of lubricant.

4. Start the engine and run the wiper motor. It should run well. If it does not, the motor should be disassembled, cleaned and inspected and a rebuilding kit installed. It is normal for the wiper to slow down when the car is accelerated, but it should not stop altogether.
