Is there any visible difference in the fitting over the motor shaft? As though its wider/deeper/longer than the opposite side---offset might be a better word?
I'm assuming the C clip groove is in the same location both motors?
Hello JWA - The wiper motor pin and groove location on the pin are identical to the point of exactly alike. The shaft on the wiper 'rod' is a given - in that it is what it is.
I am totally perplexed. Wondering if there was some old gasket or bushing or washer type material involved. It is so hard to see given the rod and shaft are so 'buried' btwn the firewall and other frame pieces.
Maybe I'll put up some photos - may answer some questions.
The "Arm" on the wiper motor *new one* might not be correct to the transmission arm / bushing of the old one.
Even thought you said they look identical?
So.......remove the arm from the original motor, with the hex screw holding it, and swap the old motor arm to the new motor, to see if this solves your problem.
**If you check the place you ordered the motor from, and look at the other part options, you'll see that Most of the replacement motors do not come with the arm in question.
I checked that to also see if they offered the replacement bushings for the transmission arms, which they don't.
Hey Wildman25 nice to hear from you. Yeah I have checked it every way to Sunday and it just boiled down to the fact I didn't understand exactly how this assembled. You can see in the photo above where it is assembled. I assembled it the same way on the old arm too. It appears the groove in the pin is NOT the recess for the 'C' clip - instead it's a thin slot in the hard, black covering (it encases the tube/shaft) that the pin goes through.
In my frustration I took a pair of vise grips to try and twist the wiper 'bar' to see the bottom side of it and as I did it "Popped" loose. I thought, ohhhh no, figured I had really screwed up. As it turned out I was pleasantly surprised to see it had meerly popped of the ball knuckle and so should simplify reassembly.
MacBuz if it makes you feel any better I also had a bit of an issue with changing a wiper motor on a '97 E250...........
I was hell bent to NOT pop the ball joint loose, hoping I could simply replace the motor somehow. Since those arms, motors and linkages are all inside the cowl not enough room to allow this easily. After struggling 45 minutes I finally popped the old motor out and had it all back together running in another 15.
Had I just been smart enough at the beginning...........
Well gentlemen, it is back together now, just finished. Again, couldn't have done it without my wife's help. My hands just don't fit those little access' they give you.
For me, popping that ball joint loose was worth it. The added latitude it gave in manipulating the arm to better fit the clip paid off. Not only that, but was able to have the arm out in the open so I could see exactly how the arm/motor pin/clip all went together. Getting the ball joint to snap back together was a trick. Wound up using a large pair of channel locks - there was some finessing to get the channel locks in the cowl just right - then it was a simple squeeze and it went "POP".
Not sure I could have done it without your help as well so I thank you. Gonna start thinking seriously about the EGR Tube now. I imagine the place to start there is getting the air cleaner assembly off and out of the way.
