Electric Wiper Conversion on the cheap

[kustombrad]

They only arc at 120 degrees which is perfect. Only real complaint I would have is they're only one speed!

Does anyone have details on this setup? I think someone was making and selling the aluminum pieces>

Here's your "Bad to the bone" wiper guy! http://67-72chevytrucks.com/vboard/s...=340194&page=5

[ratrodmiller]

wow Ive been wondering about this for along time , thanks man for the detailed post .

Aha! that makes sense.

Although one speed kinda blows, but on the other hand, most of us don't plan on driving these cars and trucks in a downpoor do we?

I plan on using a motor from a pontiac/oldsmobile mini-van. Their wipers rotate same as ours. So I hoping the mechanics will work the same and then it will have delay and 2 speeds. I'll keep yall posted.

what years? and for our 47-54 trucks don't we want a wipermoter that sweeps 90* or am I being dense?

It's not so much the angle that's critical, it's the motion. With the right spacing from the pivot point of the motor shaft to the pivot point of the connecting arms, you can get the right sweep on the windshield. Again, the issue lies with a self reversing motor and most modern ones go full circle, which won't work in our trucks.

Cheers,
Ted.

The one I'm pulling from will be early '90's. I got the GM parts guy to send me a picture of the mechanics see what you think, Thadious you may can chime in and tell me if you think it'll work.

[Thadious]

If I'm reading the picture correctly, the top "Y" is a stationary brace and the bottom "Y" is the motionary section. Judging from linkage setup, it looks like it would turn a single direction rotation into a self-reversing momentum at the secondary pivot point.

While this looks like it would work, I think you will find a slight bit of difficulty modifying it to work with our trucks for a couple reasons... 1. The lengths of the arms will undoubtably need to be altered and 2. You will need to add some hard mounting points for all the parts. I'm not saying it won't work, because it looks like it will, but you may need a little research and some trial and error to get the angle of sweep to what you seek out of it.

On another note, I'll be researching some other motors here soon... seems like I've got more requests than I can pass up and I'd like to see if I can get a two speed setup!

Best of luck and cheers!
Ted.

Thadious you are exactly correct, the motor does turn in one direction. So now I'm in the debate to try and make my system mimic the picture above or go back to the yard and buy a single speed rear window motor.

SSR check out the 2000 S10 blazer rear motor its the same size as the earlier models but 2 speed, my wife's has delay and low, same speed as the front low speed.

[Thadious]

Ummmm... delay and low isn't two speed. You can get that with the 91 blazer motor, you just need the right switch. Delay is one thing, but two speed is high and low speeds... sorry.

I looked on Fleabay at the 2000 blazer motors (and pretty sure I found one in the yard during my searches) and they are a single direction rotary motor.

Cheers,
Ted.

I thought it moving intermittently and then constantly was two different speeds, my bad

Could a full circle motor circuit board be reconfigured to go self reversing?

[tmoble]

>>> "I thought it moving intermittently and then constantly was two different speeds, my bad"

I could buy into that, I live in Phx area and would get more use out of intermittant than Hi spd. Also have a 01 Blazer in the driveway. Wonder if the wife would notice anything?

[1952ssr]

I got with Flipper on the Killbillet site about his '48 cause I was looking back over his thread and saw his wiper setup. I pm'd him to find out if the motor traveled in full circle and he confirmed it did. Here is a picture of his unique solution.

[RootBeer 6117]

Wow that looks interesting....

[1952ssr]

Well, time has allowed me to get my wiper configuration done and I wanted to share the pictures and a diagram to help any guys wanting to use this set up. It wasn't as hard as expected although it did get a little frustrating at times. But, my pain is your gain. The attachment gives you some measurements to go on, I had my air/heater box to give some slight clearance problems so yours could be a little different. Good luck

[mknittle]

thanks 1952,
That gives me a good place to start. can you tell me the dimension between the centers of the motor shaft to the pivot is?

Thanks mark

[1952ssr]

I think it's 2 3/4 or 3". I forgot to measure that dimension before I put my cluster back in.

[Dan Bowles]

Like a choo choo train! I've been thinking of a bicycle crank idea on an S10 FRONT motor but have yet to implement. This is a great way to convert the rotational motion to a side to side motion. Thanks for the great idea!

Thanks, I was just being lazy.I am nowhere near that far yet but thinking about it anyway. lol

[RootBeer 6117]

COOL Stuff! I like it I am in the middle of electrical, once again I am going to see if I can come up with one, thanks.

[RootBeer 6117]

Hmm, this is setting in the shop and has me thinking..... 3 speed American, 2 speed Canadian I wonder...
