HELP! Trying to install new wiper motor

I have a 82 CJ7 and just bought a new wiper motor. I removed the old one by taking the 3 bolts off the motor and the nut and washer off the small bracket on the end of the motor shaft. For the life of me I can't figure out how it was installed in the first place, it was hard enough trying to get the nut off. Does anyone know if there is a video or illustration out there that shws how to install the new motor?
Thanks, Craig

So you really should not have to take the nut off of the motor shaft (it's very important that crank arm be in the correct position when everything is back together or you can break linkage). The new motor should already have a new crank arm on it, so you shouldn't have to transfer from the old motor to the new.

The way you're supposed to take the motor off is to remove the 3 bolts that hold it to the windshield frame (like you already did). Then pop the oval shaped plastic cover out of the windshield frame (the one close to the driver side). Behind the plastic cover you will find the pivot mechanism and linkage connection to the driver side wiper arm (take careful note of how that is all assembled as it is important to get it back together exactly the same way). On the pivot arm there is a little clip (kind of a u-shape c-clip thing). slide the clip off and the linkage can be removed from the wiper pivot. Then you can remove the motor with the short linkage arm attached. Another clip holds the linkage to the motor crank (similar to the one you just removed from the wiper pivot). Pop the clip off to get the linkage arm from the motor and install it on the new wiper motor. Put it all back together in the opposite order that you took it apart.

Be sure to put a little fresh grease on the linkage connectors while you're at it.

PS- you didn't ask, so I assume you found the wiring connector behind the dash..

I have another problem, I thought I had to remove the small arm from the motor. Now I don't know the exact orientation it was in. I looked at pics of new ones online but I'm getting varied results. Does anyone have any suggestions?

Doesn't the new motor have the crank arm already on it?

You're best bet is to find someone around you or one at a bone yard. If you can take yours with you, you can match it. Theirs no groove or mark so you have to mark it with them side by side.

Bolt the motor up and wire it up. Turn it on, and then turn it back off. The motor will now be in the park position. Now put the arm on so it is in the correct position for the wipers.

FYI - the wiper's resting position is to the passenger's side. If you positions them to the driver's side, the will sweep on to the hood.

Thanks for the help guys. I'm sure I can handle it now, probably have to do it by trial and error but I'll be an expert by the time I'm finished.
