Wiper motor removal

Post by Jumprun » Sat Mar 02, 2019 7:06 pm

I cant seem to get the drive cable loose from the drive socket in the wiper motor transmission. I assume its like a speedo cable with a square drive. I have wiggled and pulled to no avail. I thought it would just slide out, maybe I need to get tougher or is there a secret?
Thanks, Tom Martinez from wet California.

The quick answer is NO, it is not the same as the speedo cable. The wiper cable comes out of that housing with the motor. The end is fastened onto a disk that is turned by the motor.

That causes the back and forth motion of the cable that ends up rotating the wiper arm shafts.

See http://www.parrotbyte.com/kbc/ferrari/3 ... rmotor.htm for some background. But a quick primer, remove the wiper arms, disconnect the cable housing nut (you already did this), unbolt the motor and disconnect the wiring. Then as you remove the motor, the cable comes with it, thus rotating the wiper arm shafts round and round. As I found out, mark the shafts once the cable is removed so they end up in about the same position when you re-assemble. They wear in the 1/4 arc the wiper arm moves it and can be tight on the other portion of the rotation.

Aha! Thanks Kerry. I got it out, but the end of the crank pin on the large plastic gear got chipped so I be looking for the part. I am hoping since it's Lucas it should be available.
