Wipers, not enough arc

[petrolhead]

I have a 1967 mini and the wiper motor has a 120 deg wheel however the wipers only ark about 90 deg

Any idea why

has this just started, or have you recently swapped something (or many things) out? I had a similar issue a couple of weeks back, but it was due to one item that i swapped out had been messed about with years ago. It therefore messed everything up when swapping out for newer parts.

If it's not a new fault ie they were working and now not, we had this on a mates car.

The wheel boxes the previous owner used were wrong, we swapped them out for the smaller geared items and properly secured the wiper motor. The wiper motor was loose on its mounts and was moving during the action and translating less movement to the wipers..
