Lucas FW1 Wiper Motor

[diffwhine]

Found in a box of bits during a clearout this morning. I reckon it would be a very useful spares donor as its almost brand new from what I can see.

Some obvious differences from the FW2, but has anybody come across one before and what is its likely application? Seeing as you can't park the shaft, it must be a right pain to use...

maybe a rear window wiper motor?

Never seen one of those and Google doesnt appear to have heard of "Lucas FW1" 

RARE!

[diffwhine]

Is it rare as is should be in the Science Museum, or rare because its damn all use to anybody and better off being broken up for parts to sort out my spare FW2 motor?

Now I can see the photos it is not what I thought when I commented on the S1 forum.  The fitting is the same as those sold for boats etc..  I suspect that the innard will be the same as the FW2 so could be used to refurbish one

I reckon it would make a good driver's side wiper pretty much "as-is". The FW2's biggest Achilles heel is the slop that extended use wears in the drive dog. I'm assuming this must have a solid shaft. You do get pretty adept at turning them off at exactly the right time for them to park in the right place.

Not on the passenger side though, as I have never had a passenger yet (other than those who are also experienced series 2 drivers) that can park them properly. 🤣

Unfortunately the main drive shaft is actually too short to use as is.
I'm just a bit surprised that I cannot find any reference to it whatsoever in any Lucas manual or by using Google.

I think its best future is as a donor for my spare one which is waiting to be rebuilt. I'll keep the main casings and odd bits though just in case somebody declares that it actually is the Holy Grail of wiper motors...

Curiosity got the better of me and I have just opened it up. I reckon a result! It clearly has never been fitted and is brand new! The grease has congealed and will need changing, but there is no wear on the brushes or commutator, so a perfect donor.
The gearing is different - This one arcs to almost a fill 180 degrees, so I reckon Peter is right - probably a marine or agricultural application.

Now reborn/repurposed and now identifies as a Land Rover FW2 wiper motor. Far more useful...

A much better solution!!

[Old Hywel]

You can't say reborn! They'll be coming for you.

[Worf]

Excellent!

[diffwhine]

It certainly took some cleaning to get that congealed grease out. It had set solid.

I hope you left a note inside explaining what you did, or you'll end up as a P.O some people are so fond of complaining about.

One to confuse the archaeologists in a few thousand years, lets put it that way!
Internally once you strip out the different shaft and drive gears, it is identical and on test, runs at the same speed as an FW2. All rather satisfying in the end and I have effectively now got a brand new spare wiper motor for when one of mine inevitably misbehaves.
