Setting up Front Windscreen wiper

[Darren Oldfield]

Hi Dec

Replacement motor works fine. However, to get the correct parked position is tricky. When all parts are lined up flush to markings (as per your previous pics) the wiper still parks in the vertical position. I haven't refitted the whole mechanism yet, just tested it whilst holding in my hand. Have tried a multitude of settings and tweaks (some of which don't even move the wiper at all), but your suggested parked position seems to work best.

The wiper movement is fine, and I suspect it'll all work ok once reconnected, but I'll probably have to settle for a vertical parked position from now on, unless anyone has any other bright ideas.

Hi Darren

First of all, have you parked the MOTOR? turn the wiper on at the stalk for a few sweeps and turn off at the STALK then do the adjustments at Nut 1 to park the blade (Nut 2 should be in position as in picture)
If this doesn’t solve the problem, I have another explanation, but don’t want to confuse you for now. Let us know how you get on with this first.

The other possible explanation is that you or someone else undid and removed Nut 1, probably to have a look at the gear inside, when the put it back together the park position (of the blade) was moved from where it was before the undid Nut 1.

If what I said in my last post didn’t solve the problem and the blade is still parking in middle of screen, then, with the motor already in the park position proceed as follows:

Undo and remove Nut 1 and anti slip washer and a thick and thin washer.

Remove the “Halve” washer.
(Watch out for any other small, fine washers that may drop to the floor)

Work the hub off the main body of the mechanism JUST ENOUGH for the coged wheel to clear the teeth.

Readjust the hub to the correct park position, then push coged wheel back into the teeth.

Check that the two alignment marks line up fairly close, you can fine-tune the park position at nut 1 before you retighten it.

Note, the “Elbo” should be in the position as in picture.

I thought I'd replied to this, but can't see it. Wanted to say many thanks for all your help - your suggestion worked (although I could swear I'd already parked the motor in previous attempts). Anyway, it seems the thing to do is to ensure the correct sequence is followed i.e. park motor first, then ensure realignment flush with marks on the casing.

Hi Darren

Thanks for the feedback and glad you got it sorted, it’s a very confusing and a complicated contraption until you get your head around how it all works.
