Have just replaced front wiper motor on the Territory. I lined up the linkage on reassembly as it came apart. A “dry test” without arms, reveals it dips marginally below the parking position before actually stopping.
Speaking of analogue driven twin blade wiper mechanisms generally… Is this normal design? Or are the arms supposed to stop dead at the bottom of their travel when parked? |

Maybe with the stress of draging a wiper blade it wouldn't overrun?

The crank going from motor output shaft into the linkages as well as the pivot shaft crank length will determine wiper sweep angle. When it parks it should just stop, but also take into consideration the momentum of the armature turning. Last edited by Franco Cozzo; 02-06-2022 at 06:54 PM. |

How the crank is positioned on the motor shaft is going to effect where it parks on the windscreen. If you get this position wrong you won't park the wipers where they are supposed to park on the windscreen.
You'd want to replicate it as close as you can from the car you are replacing the motor on with the motor in its park position. |

I did, and my observations afterwards reflect something I’d never really thought about before - which is why I’m asking.
