Installing electric wipers on my MC9 (formerly "What pain in the arse!")

[gumpy]

Craig,
   We checked ours by using the "wet arm" washers to keep the windshield wet (and check washer operation at the same time).  Jack

Jack,

I will do that this afternoon when I get the new blades on. But it won't be half as fun as sitting in a real rain storm!

Ok, here's some photos...

First the original bus motor and one of the new assemblies before modification. Then the new assembly after a bit of modification.

Next, the washer bottle, and the final frontal view.

The washer buttons on the new arms suck. At least while the coach is standing still. Hoping they will work better when doing 50 mph down the road. Otherwise, I'll have to make some further modifications.

I got the sweep just about perfect, though.

All in all, it's going to be good, I think.

Oh, here's a photo of the switches. Couldn't mount them in the original holes because the body is a large box the interfered with the dash angle.

Nice post and pics! thanks

Just curious, why do they suck? not enough volume? not enough pressure? not sprasying in the right area? When I installed our wet arm wipers (attached to ORM arms), I had to "aim" them.  We used a separate universal pump for each arm, both feeding from the OEM tank.  Jack

I think the volume is ok.  Pressure is probably ok, too, but could use a bit more. I like the idea of two pumps. I have another tank in a Ranger I'm getting ready to scrap. Maybe I could mount
it next to the other one and run each side off a separate pump. I may disconnect one side and plug it and see if the other side works better of the single pump.

The arms have little round buttons on them up near the blade hinge. There are 4 holes around the button that spray. While sitting in the driveway, only one or two of the four streams
actually hit the windshield. One sprays off at a 90 degree angle towards the side of the bus and never touches the glass. There is no adjustment or aiming of these.

They may work better when traveling. We'll have to see next time I take the bus out on the road.

It's not raining, yet...

Craig, I have an immersion fuel pump from a VW Cabriolet you can have. It's used but still puts out about 65 psi at a pretty good volume.

Hmm...  Seems like a lot of pressure for a windshield washer. Would probably go through a gallon of fluid pretty quick.  On the other hand, it might knock the bugs right off the
windshield, too.

Let me think about that a bit.

Best of my memory Fred Hobe has a "kit" or set up that takes much of that work out of installing electric wipers on an MCI. I don't remember the price as I never got a chance to take our MCI's (back when we had MCI's) down and let him install me a set.
FWIW   BK

Our wet arm nozzles consist of 2 small round pieces of plastic attached near the pivot point at the center of the arm.  Each nozzle has 1 opening and can be aimed by turning with a straight bladed screwdriver.  Jack

I have a set of those nozzles, and may end up adding them to the arms. I bought them awhile back to put on, but never got around to it.

Craig, your new wipers look exactly like they were made by Autex, you might check them out if you need information!   http://www.autexacs.com/ContactUs.htm
