Wiper motor not lining up to linkage

[Jay Bee]

Did you try removing both linkages from both pivots then putting the 293 on the crank first, then to the left pivot. Then putting the 291 onto the left pivot and lastly to the right pivot. Basically working backwards from the crank. Of course having the motor in the park position too, although I don't think that would matter if the wiper blades aren't on. I feel your frustration.

I have a 2 speed motor, so it might be different. But I had a bear of a time getting things to line up. Mine had a funny spring clip thing that I couldn't get lined up with the arm and the motor. I think what I did was have the wipers unmounted and play around. I also had to loosen up or even remove the wiper motor soI could manipulate it enough for things to line up. It might even be easier if it isn't in park but half way though the cycle. It might put it into a different position that would be easier. This all assumes you have the right part.

Okay...thought about this in bed last night .....You have all the correct parts....so I'm leaning towards the motor not being parked even know you are certain it is....For argument sake, lets say it's not.....In normal operation, the crank arm goes around and around 360* that's how it works.....
So I suggest turning the pivots until you can hook up everything....then power up the system and operate it WITHOUT the wiper arms in place....once your 110% sure it's in the parked position, install the wiper arms/blades

This is my wiper motor.  Part number   2926919

Also, here is a video of it in operation and parking at the end.  This ends with the crank arm pointed toward the driver's side and slightly up.

So you're saying no matter if you turn the pivot, there's no way to hook the rod onto the crank arm ? Great, another sleepless night

@anlauto   Thank you for trying to help me.  Yes, I could rotate the crank arm and connect the linkage.  However, if I do that, when the motor comes back to park, I am pretty sure that something will break or bend.  There is approximately 1/4" of mismatch between the pin on the crank arm and the bushing in the linkage.  That is a lot of interference when the motor comes back to the park position.

Can anyone look at the video in my earlier post and tell me if the crank arm seems to go to the correct place when the motor goes back to park? 

Do I have the correct part number for the motor assembly?

Thank you.

2926919 is a C-body motor. I believe the difference is the wire harness is longer than a 70-71 e-body motor, which is 3431077. Looking closer at your picture, is it in fact clocked correctly then? I believe it needs to go up a notch yet?

[anlauto]

Does anybody have an E Body where they can take a picture through the cowl vent screen to see the location of the crank arm when in park ?

Some time ago I posted these in another thread but I can't find it. "077" in Park position.

@GoMangoBoys  Did you ever try my suggestion of connecting everything backwards while it's in the cowl?
1. motor crank to 293
2. 293 to left pivot
3. left pivot to 291
4. 291 to right pivot

I understand that those circular clips can be a pain but if you can just mock it up without them you might find what's going wrong.

@EV2RTSE  The top plate appears to have a little tit on the side.  Mine is where in your last post you show the yellow line.  Are you saying that I should rotate it to the place where you show the red line since this is a C-body motor in an E-body car?


@Jay Bee  I did do that (sort of).  I did not unclip all the pins, but I did unbolt the pivots from the cowl and try to connect the 293 link to the crank first.  It just shoved both pivots to the left far enough that they rubbed on the opening and the bolts would not go in.  I will take it all apart and try connecting one link at a time.

Thanks for the picture John, it looks to me like everything is correct

My apologies, looking at it on my phone & laptop it looked like the tit was where the red line is and so I was thinking it should be moved up if possible, to where the yellow (was trying to make it green, lol) line is. But as you mentioned you already have it there, I can see it better now looking at it on a larger computer monitor here at work.

I would be curious though to maybe move it back a notch or two anyway and see if that makes the problem even worse?

Clock the motor as if it was an 077

The motors are basically the same its just clocking, crank arms and wire length. Set the motor up like its the car you're working on.
