wiper position

[triumphelan]

I have ask this question before, and got no answer ,which is very unusal for this group,so here we go again .
How can I change the park position of the wipers ,at present they park on the near side and the MOT tester was not happy that all of the drivers side was not swept ?

since when has that been part of the test for a classic car?....you shouldnt get an emissions test either.!!!....take it to a different MOT station.....or pull your wiper motor and turn it round.....that could lead to drilling extra holes in the glass......er......dunno in that case......what about connecting the motor in reverse....ie + where the - was and visa versa.....

The wipers on my S4 park on the near side and my MOT chap does not have
an issue with this. Changing the parking side is not going to change the
swept area. Go to a different MOT station, one that is more sympathetic
to classic cars.

I have many tales of woe, incompetence and ignorance with MOT stations
and classic cars.

Changing the park position of the wipers will not change the position of the
arc or the angle through which the wipers sweep, so will not aid in wiping
the drivers side of the screen. The only thing that can be done is to change
the position of the arc by repositioning the wiper arms on the drive
splines. However this may lead to the wipers being parked in an awkward
position halfway up the screen. It will probably only help if the wipers are
currently being parked almost on the bonnet.

Turning the motor round or changing it's polarity will make no difference
either.

I think the MOT Testers Manual is online somewhere, so it might be useful to
find out what, if anything, it has to say about wiper arc and how this
applies to "classic" cars. In the end if you have a stroppy MOT Tester all
you can do is appeal against a failure, not recommended, or find a more
friendly tester.

There's an interesting article here:-

http://www.s-v-c.co.uk/SVCWIPERS.HTM

It seems it's possible to change the wiper arc and swept area by changing a
gear in the wiper motor. I suppose it's possible a second hand motor could
have been fitted which has the wrong gear fitted.

John,

This has been covered in some detail before, it's in the files, but here goes !

You may just need to remove the wiper arms and rotate them slightly on the spindles to cover more of the driver area; do they presently sweep to the bottom of the screen, and are they parallel to it ?

The wiper park position can be changed by removing the cover of the wiper motor, and rotating the contact position of the brush switch. However, you will now notice that because of the crank of the wiper arm, the blades will now be at an angle instead of parallel to the bottom of the windscreen,so you will have to buy a set of arms cranked in the opposite direction.

As has been suggested, it should be much less trouble to change your vehicle tester.

Hi John,

There is a "can" like cover on the wiper motor. IIRC it is secured by
3 screws, loosen them and then turn the can until the arms park where
you want them. I ahve no clue as to which way you need to turn the can.
Be aware that the wiper arms may have a bend in them so that they rest
parallel to the widscreen edge. Also I do not belive that the park
position will alter the swept area as they wiper arms will still be
pivoting from the same points. If you should do this anyway, be sure
to remove the wiper arms, attach a piece of wire to the wiper post to
indicate arm position. It can be bad news if the wiper arms attempt to
sweep across the body, the trip over the gasket can be really bad.
Just keep the wire short so it won't come around and scratch the paint.

[saildrive2001]

There are two separate issues here.
The park position is controlled by a series of spring contacts running on a
disc which stops the wiper motor in the correct position. Maybe you have an
export motor which would park on the right hand side of the vehicle. My
wiper motor has the following identification on it. A small circle which
looks like the Mercedes hood ornament followed by 75660A. underneath a
another number which is 54071569B. The cover plate also has an arrow showing
the park direction.
The second problem of not wiping the drivers side fully is controlled by the
initial geometry of the wiper system. With any car the wiper arm pivot
points determine this condition. Modern cars are designed to sweep a larger
area of the drivers side than the passenger side. This requires a different
location for the wiper arm pivots for right hand & left hand drive vehicles.
In the days when the Elan was designed I don't recall that there were any
requirement to have a minimum area of the glass wiped. Hence the cheap
solution was to use the same wiper system for both rt.hand & lt hand drive
vehicles.

John,

I agree with Sean's answer!

1. Move the arms so that they sweep lower on the drivers side

2. Change the motor or gear within so that it parks on the opposite side
It would be pretty easy to find a motor which parks to the O/S (late
Midget)

But why bother...........


3. Take it to a sensible MOT tester.

No it will not change the degrees of sweep but with the appropriately
cranked arms for driver side parking it will then sweep to the bottom
edge of the screen assuming the arms are set to park flush with the
bottom of the screen.

If you want the motor to park on the opposite side you need to either
change the motor completely or alternatively the gear within so that
the park pin engages in the correct place.
