windshield wipers? 818 s

[indiana818]

i read somewhere that someone added oem wipers. i don't have my chassis yet ,not till next month
but like the idea. is there instructions on how to do this in the manual? does anyone have any advise for me?

[K3LAG]

FFR says their wiper solution is coming 'Soon.' It will be dual wiper using OEM motor and linkages.

Outstanding, at first I was upset that my production date is not until next fall but the car just keeps getting better and better developed. I am just keeping busy preparing my 2004 donor car parts and reading all the good advice on these threads.

[Harley818]

Hoping they will be in by May......we get a bit of rain here in Vancouver....

Reviving this thread. Sneak peak at my solution using the Subaru wiper and no cutting of the hood.

Bill how the hell do you get your windshield frame so far back, my master cylinder barely extends past the vertical wall of the fiberglass and yours must be a full inch or more??? I can't get my windshield squared up with it so far back...

Haha. Must just be the angle of the photo. Mine looks about like yours from the side.

I'm all the way back in the slots, which puts me about 1/4" too close to the roll bar compared to the soft top measurements in the manual. Hopefully that won't create an issue, but that's a battle for another day.

Nice job!

[matteo92065]

I like it. A couple more details and pictures please.

[Frank818]

That's exactly one of my 2 options! Did you extend the small side-to-side arm by 10mm in order to have a full 180-deg sweep?

[billjr212]

nope. Removed the passenger side arm entirely and shortened one of the links to go directly from the motor to the driver side arm.

[billjr212]

I'll post detailed photos once I confirm it actually works. I did take a short video today, but don't have a YouTube account set up. I can email to someone if they want to post it.

[billjr212]

Video wouldn't attach to an email (too big) so I just figured out the YouTube thing. Much easier than I expected. This is just a quick initial video showing the sweep. You can hear it just touch the lip of the hood and windshield trim at the end of the range of motion. I am fairly certain I can adjust this out. More to come this week. I was able to make this out of the stock wiper with some rudimentary welding skills. Uses the old passenger side arm attached to the driver side post with revised linkage.

pretty good coverage!

[Frank818]

That's almost 180-deg! Pretty good!

[Harley818]

nice work Bill. When you get a chance, can you post details. I don't like the hood cutout job either, so I like your solution.
I just took out my wiper assembly a couple days ago and laid it in place but the arms rub right up against the fiberglass windsheild frame......
Yours is a good option and i didn't think one wiper would be enough but it look like it has full coverage.

[billjr212]

Will do. I still need to do final fitment on the hood, which means I need an extra set of hands and a time when my daughter isn't sleeping in the room above so I can use the dremel. First is easy, second has been an issue. I was thinking I'd pull the wiper off then and do a short 360 video showing the new linkage and attachment points rather than a bunch of pictures. If anybody wants to see a photo from a specific angle though, let me know.

[Hendow]

Very nice job Bill.

Looks like a similar design to mine, which I found worked very well with minimal trimming of the bonnet (sorry... hood!)

Can you fit a larger wiper blade to give you a bit more swept area? Also, I used a simple clip on washer sprayer in order to comply with local compliance requirements.

Cheers from Down Under...

Hi Hendow,

Do you have a picture of the car with the hood in place so we can see just how much you had to trim?

Thanks,

Buzz

[Hendow]

Hi Buzz,

Apologies for the delayed response...

Here are some pics with the hood on:

As you can see, not a lot of trimming was required to clear the wiper arm.

I hope this helps!

[flynntuna]

Looks like extra venting for the radiator as a bonus.

[Frank818]

Hey Hendow, there might be various ways to extend the sweep (make it over 90-deg), which one you tried?

I like this idea. Nicely done!! I am trying to picture what you did to the linkage to make it work. Can you get a short video such as Hendow's to see the actual mechanism?

Thanks,

The sweep should be modified by changing the motor to wiper arm length ratio (I'm not talking about the wiper arm that actually holds the rubber blade). The length of the wiper arm must never be shorter than the motor arm. The length of the link between the two arms must be equal to the distance between the pivots of the motor and wiper arm.
If the length of the wiper arm equals the length of the motor arm the sweep will be near 180 degrees. I don't think you want 180, its way too much. If wiper arm is ~1.43 times the motor arm, sweep is ~90 degrees, If wiper arm is ~1.15 times the motor arm, sweep is about 120 degrees.
I was ready to modify the length of the wiper arm but my sweep ended up perfect.
These are pictures of what I did.

[Buzz Skyline]

Thanks, Wallace and Hendow, for posting your solutions to avoid cutting the hood. I did something similar

https://youtu.be/gqekiEtdt4U

But I modified the FFR kit instead of making my own bracket.

[STiPWRD]

Buzz, what was the mod? Was it straight forward? Thanks for posting

Edit: Nm, I saw your post on Andrew and Tamra's Thread

[Buzz Skyline]

One other thing I didn't mention is that I attached the bracket to the windshield lower than the FFR instructions call for. It's about 1.25 inches lower, which is why I had to cut the space for the wiper actuator arm to swing. Also, I centered the wiper on the windshield ( that's where the one inch shift in the bracket location came from.)

I left off the arm that turns the driver side wiper (that's pretty obvious), and switched the location of the rod that goes to the other wiper to the inner bearing thing (whatever that's called) to increase the range of motion of the central wiper.

[Frank818]

Hey matteo, how do you know the length of the pivots link? The one I welded is too long as it hits on the wiper arm pivot in 2 places and the motor arm can't do a full 360-deg.

Reading 10 times your post I can't figure out how to determine the length of the link. You mention it needs to be the same distance as the distance between the 2 pivots. Sure, but that distance changes if you turn one of the 2 pivot and not the other, so at which angle should the pivots be when I measure the link length?

Currently I have 6.25" between each pivot's center and it's too long. I guess I'll try to shorter it until it pivots very close to the wiper arm pivot. Trial and error, there still must be a way to calculate its length before I weld.

[matteo92065]

i don't know the measurement. but I put this together.
IMG_0111.JPG

then it will never bind, or hit anything.

[tmoretta]

By the way, anyone know what size nuts are used to fix the wiper arms to the subie wiper motor shafts? Mine are lost.

AWESOME!! Exactly what I needed! Now I get everything! The distance between the axle centers is exactly 5.25", on my 2003 motor assembly, which is probably the same as 2002 and 2004, but I don't know for others. I will unpaint, re-cut, re-weld, re-paint and fix it.

By the way, anyone know what size nuts are used to fix the wiper arms to the subie wiper motor shafts? Mine are lost.

Small ones, I still got mine on the rotating shaft/stem/rod that supports the long wiper arm, I will check that this week, if no one does it before...

[matteo92065]

One more thing, if you set it up like my picture, the wiper will park on passenger side. 2 o'clockish. If you set the wiper arm in the 5 o'clockish position it will park on drivers side.
Took me a little while to figure out how out right hand driving cars were doing theirs.

[Frank818]

Seems to be M9x1.5 or M8x1.5.

Ok so I rewelded and it gives this:

2015-06-24 12.28.31.jpg

This mod does *NOT* work at all as it is on the picture!

I ended up with OEM 90-deg sweep!
2015-06-24 12.27.01.jpg2015-06-24 12.27.51.jpg

And I totally don't understand why... I have the round link 5.25" long between pivot centers, which is same length as the axle centers. I could have it longer, there is space, maybe I need to reach the very maximum, but it becomes more complex to ADD 0.25", not easy to weld and I need to do 2 welds if I make it longer.

I have to think about what to do, but clearly this did not change anything.

I need a good 150-160-deg in order to wipe 80% of the windscreen's surface.

[Buzz Skyline]

Do you still have the other half of the assembly that you cut up? If so, the arm on the other side has two connection points on it. Use the closer in one to get a larger sweep angle. See this image

linkage photo 2.JPG

That's the end you need to use. But attach the arm from the motor to the other point (the one it's not attached to in the stock configuration).

You can see what I mean in the video of my wiper arms at at about 15 seconds in https://www.youtube.com/watch?v=49qF...ature=youtu.be

It's kind of hard to explain in words, but if you do this it gives you enough range to sweep essentially the whole windshield.

[Frank818]

Interesting, you have a much different setup.

I still got all the parts, though many are cut, but I can re-weld.

I have put numbers on the picture, if that helps, cuz yeah it's not easy to see exactly what I need and what makes it sweep more.

You have to unbolt the motor arm and re-position it 180*.

Look at your picture, and then my picture. The motor arm needs to line up with the link arm, like you have, BUT with the motor arm AWAY from the wiper axis.

I'll work on another picture. Mine is an 06 Impreza.

If you want 150* sweep, measure the motor arm, then multiply that by 1.035; and that will be the length of the wiper arm needed. The factory set up is actually close to that.

[matteo92065]

Here is a drawing trying to describe the sweep angle. THIS PICTURE DOES NOT SHOW IT IN THE PARK POSITION. lines would be overlapping if I drew it in the park position.wiper layout.JPG
