Thread: updating wiper control on county 110

After days of rain and using the wipers I feel the need to upgrade to three speed wipers fitted to later defenders.

Does anyone know what's required to fit say a 300 TDI defender wiper control?

Also, the range of sweep on my wiper varies. Most of the time now it slams down on the wash nozzle on the firewall. Anyone know what has caused this to start.

thanks

Can't help with the three speed bit, but the change in sweep is probably because the serrated bush the wiper arm goes on has moved on the shaft. Assuming it is the same as mine, the bush is clamped by a screw which may be slightly loose, or worse, seized in its thread but not clamping tightly to the shaft.

Once this bush is secure on the shaft, the arm can be reset in the correct position by pulling it off and putting it back rotated one or two teeth as necessary.

There is a slight possibility that the problem is the wiper box is loose on the bulkhead, but I think this is unlikely. It is clamped by the nut round the shaft, so you should be able to see if it is loose.

Yep as jhon said your cam thingy is wobbly. easy fix i greased all the things that should be greesed at the same time now i have lossed my squeek as well.

would it be loose if it is reaching fully the other way?

I have fitted a intermittent wiper control to my 110. It is connected into the wiring of the wiper switch and is controled by a knob.
I had to order the controller, wasn't expensive, just say if anyone wants to know more.

Possibly. It will probably be getting the extra travel with the help of momentum and gravity. The only alternative would be a most improbable change in the effective lever length in the motor gearbox itself - and this would apply to both wipers.

Fold the arm back, and check for free play.

The speeds may be built into the wiper motor. I know with series landies that was the case, as I fitted a 2-speed series 3/110 wiper motor when I rebuilt my IIA. The switch is immaterial (I use a 2-way toggle switch for mine).

So I would suspect you would need (at minimum) to get a wiper motor and switch from a defender.

If the motors are like the series items, they have a +ve feed from the ignition, and the switch sends the -ve.

As for the variable sweep - check the wiper spindles/heads/pins aren't worn. And check that the tube/screw is nicely lubed.

EDIT - FYI - I also had to change the drive gears when changing motors. The 1 and 2 speed motors have completely different size drive gears - as they must have a different stroke.

Your right, the motor speeds are in the motor. It is done by the windings. The slow speed is done by motor windings working against each other abit and the fast they work together.

However is you were into electronics you could just get a motor speed controller and then you could make your single speed motor go any speed from 0 to flat out. Intermittent involves a separate arrangement of relays. In a defender the difference is the switch and it has the intermittent unit hidden away in the dash somewhere. So in theory you could transplant this to parts in to your LR with two speed wiper motor and it would work just like a defender. If all the parts will actually go together is something it don't know (e.g wiper switch to colomn.)
