Wiper pivot assembly

[comet_666]

Got new set and they actually pivot! Once I hooked them to the motor no more pivot? I assume because the wiper motor locks or did I install them incorrectly?

I've never seen the brass clips on the arm joints like that. I assume if you remove the arm from the motor they move just fine? Do you have the correct crank arm for your motor? The 2-speed and 3-speed crank arms are different as are 68-70 versus other years and b-bodies vs. non b-bodies. With the transmission arms disconnected from the motor, does the motor turn? If you disconnect it from the wiper motor and can pivot the wipers by hand, and the motor turns when the switch is turned on with the arms disconnected, I'd say it may be the wrong crank arm.

You want to test the motor with the arms disconnected, test the three speeds, turn it off and watch that it parks. Then, when parked, attach the wiper transmission arm to the motor. The connection is indexed so it can only be connected one way.

Correct 3-speed crank arm:

Also, make sure if you've installed new pivots and arms that you installed new gaskets and seals. You will get water through the pivot holes without correct/new seals. I got mine from Detroit Muscle Technologies.

I pulled the crank arm and gaskets off my old assembly, the new one did not come with those. My gaskets are new.
I dont have electric hooked up in car yet so I can't test my passion4mopars restored motor (i'm sure it works)
Was just wondering if it should still movve or not?

They will not move if connected to the motor - unless you flip the switch.

Those brass clips are for the wiper crank arm only. The other ends get plastic bushings. you can get those at RT specialties.

Ahh  ha!..  Thanks guys!

Like Banana Dan said, I would cycle your motor first before you attach your linkage. I would also not have the wiper arms on either.

[BananaDan]

Yes!  Good point! If you have it connected and the wiper arms on before knowing the motor is parked and turn it on, it could make the wiper arms go down and into your cowl and scratch the shit out of your paint! Wiper arms go on absolutely last after everything is connected and tested.  To answer your other question, no, the motor will not turn or move unless it is turned on electrically, so if you have it connected to the transmission arms and they won't move with your muscle power, that is correct and expected. Regarding re-using your seals, the white ones if they aren't messed up should be fine, but the black rings and butyl tape are what really keeps the water from going through those pivot holes in the cowl. I recommend you buy new ones to be sure you don't have to deal with a leak after your car is back together. It is much easier dealing with the crap under and inside of your dash now versus when she is fully assembled. Trust me.

Verify the part number on that crank arm now while you have easy access to it. Just because it was on the car when you got the car doesn't mean it's correct or original (unless you're the original owner). My car was a frankenstein when I bought her and had a myriad of A, B and C-body parts on her but I didn't know it when I bought it and found out along the way as I learned. Its easy to take it off the motor now and look at the part number stamping on the arm.

again Dan is right.

First connect the wiper motor before you connect the linkage. Test the wiper motor and make sure it parks correct before you connect the linkage. Then test the linkage with the motor all together and lastly put the wipers on.

[comet_666]

Great advice guys, I will do exactly that. Don't need a mishap right off the bat!

Hi comet_666,where did you get the new wiper pivots from?

[comet_666]

Found them on ebay, they are not new just restored very well 

[bbody68]

Thanks comet,will checkout eBay.

[A383Wing]

Found them on ebay, they are not new just restored very well 

looks more like sandblasted to me....not sure how you can "restore" one of those pivots

[PlainfieldCharger]

Did my set. I soaked them in mineral spirits for a week. Added a grease fitting to the side and greased the @%# out of it. It is so smooth now...
