mmaupin Posted March 21, 2016 Share Posted March 21, 2016 Wondering if someone knows how the Windshield Wipers work. Sound like they work off of air or maybe vacuum or both? Any help appreciated.

Mike Posted March 21, 2016 Share Posted March 21, 2016 Last time I looked they work back and forth. Sorry it's been a long month. Yes they work from the engine compressor. Most of the time when they move slow it is because of slug in the system and needs a good cleaning. Or it needs a new govner. Hey I still can't spell when I saw posted Christy Brinkley, maybe if I had her number then I could get well or maybe better? 1 Quote Link to comment https://www.bigmacktrucks.com/topic/44408-windshield-wipers-on-my-59-b-model/#findComment-328062 Share on other sites More sharing options...
Freightrain Posted March 21, 2016 Share Posted March 21, 2016 Yup, air. They can be finicky, but once you have the system good they work fine. Mine will near throw the blades off it runs so fast. The dash control will usually have a bad o-ring, which means it leaks air. Beyond that there isn't much to it. The wiper motor itself might need some cleaning and attention, along with the air lines to it. They swell up or get hard and plug up and won't pass enough air to make them move. The motor is easy to remove off the fire wall. Note which hose goes where so you can assemble it again. I pulled mine apart and cleaned the valving inside and put it back on with some new supply lines. Wow, what a difference. Quote Larry 1959 B61 Liv'n Large......................

mmaupin Posted March 21, 2016 Author Share Posted March 21, 2016 Thanks guys, all of that makes perfect sense. Do the wipers get full line air pressure or is there a regulator somewhere?

siding guy Posted March 21, 2016 Share Posted March 21, 2016 Probably full air to on off knob which acts as a regulator Quote Link to comment https://www.bigmacktrucks.com/topic/44408-windshield-wipers-on-my-59-b-model/#findComment-328109 Share on other sites More sharing options...
Freightrain Posted March 22, 2016 Share Posted March 22, 2016 Yes, full air pressure. The exhaust from the motor has a little "muffler" on it. I removed mine as that is also a restriction for air flow. It is NOT like you will ever hear the air wooshing out of it while driving a B model!!!!!

mmaupin Posted March 22, 2016 Author Share Posted March 22, 2016 Thanks guys! That was a big help. The maintenance manual I have addresses all kinds of stuff, but not the windshield wipers.

No, I ran across a guy at a show who worked on air wipers out of his house/personal shop. He did a set for a friend of mines C cab Ford that he had previously been told were not repairable and were NLA.
