windshield wiper motor assembly

[max hendrix]

Thanks everyone. I will get one ordered.

I pondered several ways to fix it by drilling and tapping with a screw to hold the arm on Or threading and slipping a sleeve over but for less than $20 I will gladly order a brand new one and be Happy.

Next time I need one I will not remember that it's called a "Pantograph"".

Be sure to measure the spacing before you order. I think I remember the measurements are either 1.25 or 1.75. Look at the website for specifics.

Shipping was almost as much as the part itself but it did arrive quickly and fit perfectly.

All good and a lot easier than trying to repair the old one.


Thanks for the help in locating a source.

You have the nuts off,right?
Then use a pair of channel locks,but first fold the arm out,then place the channel locks on the threaded stud,and one jaw on the wiper arm,gently squeeze while pulling on the arm.

There is a small hole drilled through the lower part of the arm near the shaft which is used to place a small finish nail throught to hold the arm back allowing you to remove the arm with out the spring pressure.

Look for the hole and get a small finish nail that will slide through it, lift back on the wiper arm and then slide the nail through both holes which will hold the arm back.
I then used a tie rod tool to wedge between the arm and shaft to pop the arm off.

To reinstall just place the arm back on, tighten nut and pull back on arm to remove the nail.

Easy as pie.

Thanks for all the advice, it worked great, also found a older blog that gave a valuable name called Schoolbus parts Co. Very helpful in getting the correct measurements Bob

Before I start grinding on a new wiper motor threaded shaft like other wog members have done, anyone have a source for this type of wiper motor. I ordered the WM612 but mine has this slotted shaft and is slightly larger.

For what it's worth, on my bus I had some conglomeration of old/new mismatched parts so I decided to replace all of it - wiper arms, motors, and all hardware related. Nothing had to be modified or drilled out to use these parts.

Here are the parts for doing one side that I ordered from midwestbusparts.com :

1 x Screw & Nut For Wet Arm (16-Z-345423) = $3.49
1 x Hardware Kit For Dyna Pivot Shaft (16-P-300K) = $9.99
1 x Adaptor For Pantograph Arm, Dry (16-Z-200241) = $16.99
1 x Dyna 24" Pantograph Arm, Wet (16-AD-200480) = $44.50
1 x Crank Arm, 1 1/4" (16-C-200192) = $9.75
1 x Common School Bus Wiper Motor, 12V (16-M-900) = $69.99
1 x Bracket For Wiper Motor (16-M-900B) = $15.00

As you can see it was $180 for everything, but it's all new and works great. I did both sides. This is for the fold-down type arms that make it easy to change wiper blades.

Nobody makes a wiper motor with a shaft like that anymore, you will just need to buy the correct crank arm to match the new motor. midwestbusparts.com has them. It's a 1.25" arm iirc.
