Title: Wiper Arms - Range of Motion
Post by: CJTHREEA on October 13, 2016, 11:39:47 PM: Does anyone know what the range of motion degrees should be?

My wiper motors are wiping through at least 120 degrees of motion...

Granted I have M131 motors but I understand these should work .... :o

I don't know the actual range of motion, but 120-130ï¿½ is about all you want.

Assuming they are positioned in the stock location, when 'parked' at 0ï¿½, the top of the wiper comes pretty close to the edge of the windshield when reaching the degrees mentioned above.

I can measure the angle tonight if you want it, but my motors are SF-616...The standard issue for the CJ3A.

I'm thinking mine are getting around 120/130 as well.

Is starting position towards drivers side or passenger side?

I have a 2A but it has a 3A windshield so I figured it more appropriate to post here.

After looking at the size of the arms and blades I had the wrong ones too as I've seen the 3A windshields blades are 9" - just not sure if my arms are wrong too - I'll have to look for a model number or something on them.
