Replace wiper motor for 2speed.
Hey guys!
Wiper motor getting sluggish, won't clear on a dry screen.
So found a two speed motor online for mg mini etc says replaces Lrw 110, Thinking I could put this in and use the old gearing and wot not and wire it to a two position pull light switch (one for each speed)
The van is 1962 with clap hands wipers which I think are 110 degrees? What do folk think? Wondered if it won't park or miss the screen at the end of its arc. I've got a couple of spare wiper motors so I can take the gears from them.
Any ideas would be great, leaning through the window to flick the blade into action is a bit of a drag! Maybe a bit of string threaded through both windows and tied to the wipers

Re: Replace wiper motor for 2speed.
That's exactly what I did - though I also modified my gear wheel to have a larger sweep than standard (ended up making it too large). You'll need to make a plate to mount the round-body motor, and modify the wiring, but otherwise it all connects up the same as the old motor - you can reuse your rack, etc.
If using the standard Minor headlight switch to actuate the wipers, you'll need to wire in some relays or you'll burn out the switch. Here's the wiring diagram I used. Note that the five motor block connections are not correct - I think P and + are reversed - but it's easy to figure out when wiring up. You might also consider dribbling some oil down into the wiper wheelboxes, or take them out and regrease them - it might not be your motor that's weakening, but a wheelbox trying to seize up.

Re: Replace wiper motor for 2speed.
Thanks for the reply, I've used relays for fogs and spots before, what do they do in this instance to stop the switch burning out? Excuse my ignorance I don't get into wiring unless I have to!

Re: Replace wiper motor for 2speed.
My old saloon has clap hand wipers and they got sluggish. It was just years of grot building up in the wiper motor box. Take it apart,clean it, a bit of new lubricant....could be good for years.

Re: Replace wiper motor for 2speed.
Thanks steve Clem, I will have a look behind the oddment box, I thinks its the driver side that's sticking, could be the cable.
Thought it would be cool to have 2 speed wipers after all these years!

Re: Replace wiper motor for 2speed.
Here is the circuit that I used for 2-speed wipers on our 1958 clap hands, before going on to incorporate intermittent and programmable wash/wipe. It uses a standard Minor headlight switch, 2 x 5-pin changeover relays and some additional wiring.
Great improvement in really wet weather!
The 2-speed Lucas wiper motor that I used would not take the mechanism from the single speed motor, and the arc was much too much for the clap hands wiper boxes, but may be ok with the later ones?? I had to make a new pin to replace the standard Lucas one on the 2-speed motor. What have other people had to do to get 2 speeds on the early wipers?Great improvement in really wet weather!

Re: Replace wiper motor for 2speed.
a further possibility is to install a Lucas 2-speed wiper washer switch from a rover. Does not look to bad in the dashboard and you can connect a washer pump too.

Re: Replace wiper motor for 2speed.
no matter what 2 speeds is only going to normal speed as it is and a slower speed

Re: Replace wiper motor for 2speed.
That is not our experience with fitting a Lucas 14W 2-speed motor to replace the original 'clap hands' DR2 single speed. The 'slow' on the 14W is very much like the single speed, and the 'fast' is significantly faster, which was the reason for fitting it.no matter what 2 speeds is only going to normal speed as it is and a slower speed

Re: Replace wiper motor for 2speed.
sorry, i do not know exactly witch Rover it is from, bought it second hand
There are several differences, this is the one i mounted
sorry for german marks 4 Steckanschlüsse means 4 connectors, the shaft is 24mm as marked
off - speed one - speed two on turn, push for water pump it is connected to a Lucas 14W 2 speed wiper motor
the scratches are not from my work......

Re: Replace wiper motor for 2speed.
If I buy the lucas 14 W wiper motor, will I need to buy new switch. What else would I need to buy. I have a 1959 4 door and use it as a daily driver so faster wipers is a must in this country.minijojo wrote: ↑Thu Jul 27, 2017 8:54 pm sorry, i do not know exactly witch Rover it is from, bought it second hand

Re: Replace wiper motor for 2speed.
This is what i did (with some examples of parts purchase)
second hand lucas 2 speed wiper washer switch
https://www.ebay.co.uk/itm/LANDROVER-SE ... 3363267746
wiper motor without gear and rod
https://www.autoelectricalspares.co.uk/ ... 1521-p.asp
gear and rod (sorry, i do not remember what angle i used)
https://www.s-v-c.co.uk/product/14w-wiper-drive-gear/
Plug for wiring
https://www.ebay.co.uk/itm/Lucas-Windsc ... :rk:1:pf:0
motor mounting plate
https://www.morrisminor.org.uk/parts/52 ... ting-plate
motor mount strap
https://www.s-v-c.co.uk/product/insulated-strap---pad/
water tank with pump, i installed something like this
https://www.s-v-c.co.uk/product/washer-kit-soft-bottle/
some cables in correct colours an connectors
a bit of time to build the wiring loom
as far as i know you can not use the kit from ESM
http://www.morrisminorspares.com/body-i ... ch-p829059
because it does not work with the claphand wiper
gear of motor and wiper gearbox number of teeth must be the correct combination for the correct wipe angle on the screen
so in the end, a long way to go, and if you sum the parts prices, not a cheap conversion. I was lucky and could buy many parts cheaply.

Re: Replace wiper motor for 2speed.
... old thread I know but Richard's (IslipMinor) wiring diagram above is good but terminal 3 on the wiper motor should ideally be connected to terminal 87 on the right-hand relay instead of S2 on the switch. This avoids current being drawn through the switch when wipers are on 'Fast'.
Here's how I did it - tho' the diagram does not include the Smartscreen gizmo for intermittent wipe whicih I wired inline between 87a on right-hand relay and teminal 5 (SLOW) on the wiper motor.

Re: Replace wiper motor for 2speed.
Minijojo
I recently acquired a Rover 2000 P6 wipe/wash switch like yours in the pic can you advise please do the connections for a 2 speed motor ie... the number of the terminal of the switch to which colour wire, the green with black tracer goes to the bottom the extended push part for the electric washers.
However the switch has 3 positions in its P6 setting first click was for a delay, then speeds 1 & 2 on click 2 & 3 so need assistance please. It not installed in the van yet but I assume the switch hole needs to enlarged too. You mention it looks nice in the dash any chance of a pic please
Thanks

Re: Replace wiper motor for 2speed.
this is a picture i found how to connect the cables to the wiper plug. i used the cable colours as described in the picture. If you compare them with the picture of the switch i posted, you should be able by assigning the colours to the connectors
i´m not shure if i enlarged the whole, because someone tinkered with it before, as you can see from the scratches
if you have any further questions, please ask, i will try my best to answer
regards
Joachim

That is the plug on the wiper motor I need to know where they go on the switch that you have a photo of

Re: Replace wiper motor for 2speed.
sorry, i got no diagram of the switch, i just removed the switch and took a few photos, the colors of the cables match the information on the wiper motor plug
one problem is, i don´t know exactly what kind of switch you have. There are several different types used in several cars. You told about 4 turning positions, mine only has 3 turning positions (off, speed1, speed2). So the pin assignment on the switch may not be identical. You will probably have to measure wich plugs are connected in which switch position.
please keep in mind, that you pay attention to whether your car is positive or negativ earth wired
The Wiper motor is normally mounted isolated. So pay attention when testing.....
The switch normally does this:
off, live wire should be connected to park ( wiper turns on until parking position is reached )
first turn, live wire should be connected to 1st speed
second turn, live wire should be connected to 2nd speed
on push earth or live should be connected to the pump (depending on the wiring of the pump)
hope my statements do not confuse you.....
