And Maybe Newer! The old ones where vacume, New are Eletric but just Don't make it ! no reel sweep from these less then "American" product , I'm hopping that 1 of us has gone this route and found a Good Old non Slope Head ! Wippers that are electric and still Keep the Some What Naturel Look ! Note picture below . Please Help!
You could also search through some of the hot rod magazines, they often have cable drive wiper setups that appear to be unobtrusive, yet have good performance. Would a vacume resevoir help the original wipers?
With new or properly overhauled vacuum wiper motors, a properly overhauled dual fuel/vacuum pump, a properly running & healthy engine and proper plumbing and hoses the system is very capable. A reservoir would help a weak system. The cost of renovating a vacuum wiper system, buying modern Army 24 volt electric motors or buying 24 volt after market electric motors is all about the same. A lot will depend on how stock the builder wants his truck and if a re-engined truck, how fast he intends to drive it in the rain.
Check out marine supply stores. They have different grades of wipers in 12, 24, and 32 dc volts. they come in one or two speed, self parking, etc. Take a look at there web sitesI'm sure you will find a top of the line wiper motor.
I dont use my wipers, as I dont go out in rain, snow or anything that looks bad. I use Freeport Marine, LI NY. They have a web site, take a look.
BOB
I have the same wipers as Anthony. There really not that good but it does help me get to pass inspection. My truck is not a daily driver, If it was I would have looked for a better system or have the old vacuum motors rebuilt. But like Bob I don't take my truck out in bad weather.... I guess us Eastern Boys don't like to get our trucks dirty....
The only advantage to installing a vacuum reservoir would be that it will "even out" the operation of the wipers. There's nothing more irritating than to be driving down a hilly road in a downpour. The wipers literally "run away with themselves" on the downhill run and come to a dead stop when you drop the hammer for the uphill pull if you're running them off a manifold vacuum tap. The vacuum/fuel pump was intended to eliminate that problem, and it does...to an extent. However, when the rpm drops far enough, they will bog down a bit. The longer the hill, the longer you will be "driving on instruments." Just one of the many enjoyable aspects of living with "low tech" mechanicals.
Picture's of wiper up grade and some other things I'v been up to Can't seem to get them on here so check out my pictures on the truck on this site, File Is Called "M 37 up dates". .
