Wiper blade sweep.

Postby MogDJ » Tue Oct 09, 2018 5:28 pm

As I come towards the end of the restoration of my pick up, the more issues I seem to come across!!
When I purchased this vehicle it was a collection of panels and a pile of bits of unknown origin, which if serviceable I’ve tried to use.
On testing the wipers today, I’ve noticed that the sweep of the blades is somewhat short! The drivers side sweeps for about 90deg. thus stopping right in the middle of the drivers view, whilst the passenger side sweeps for about 120deg. or so.
Can anyone shed some light on what the problem might be, have I got a mix of incorrect parts etc and what should I do to rectify the problem.
The vehicle was originally registered in 1969, on a G plate, if that helps.
Many thanks.

check what no deg is on the wiper motor,

if its 100 you have clap hands style motor, you need to up it to 150(I think) maybe 120, you can do this by changing the large gearwheel, plenty on fleabay

Woody, many thanks for the info.
I opened up the wiper motor and found it has a 150deg gear wheel fitted. I reset the position of the wiper blade arms onto the splines so that I get a better coverage, not ideal but manageable.
Thanks again for your help.

if you have a lot of sideways play in the arms, you may need to replace cable or more likely wheel boxes,

tip, mark wheel box position, unship cable and rotate 180 deg, thus using an un used part of the gear, may help short term,

That’s great, I’ll give it a go, every little bit will help to get a clear view. Don’t want to hit something after I’ve just finished rebuilding it!

Sorry but I can't see any of the above curing the problem of one arm sweeping 90 degrees and the other 120 degrees...maybe you have two different wheel boxes ( if that's what they're called ? )....

It is worthwhile removing, dismantling and lubricating the rack as well - it might just have become a bit stiff to operate? Do you get a better sweep of the wipers if the screen is wet?
