Longbridge washer jet pump...

Country flag
Offline
I couldn't find the previous thread on the subject, or I would've added this there.

Digging through some parts in the basement, I turned up this screen washer pump. I knew that I had one, just lost track of it. I also knew that the rubber inside ceased being rubber at least a decade ago (though it did work when I bough the car in 1978).

I'm considering disecting the pump (endmill to trim off the rolled end); I doubt I could find a replacement diaphragm, but it might not be that difficult to fit a momentary contact in the case to operate an electric pump.

This is what I have so far:

Randy,
I found an article on the "tigers united" web site for sunbeam tigers by Stu Brennan that describes, with images, the conversion of our windshield washer pumps into micro switch controlled units - all encased in the original canister. I have done this for my Bugeye and for the 3000. Works great and except for the electric pump (which you can hide) no one would ever know.

Thanks Lin, you've just confirmed what I was thinking. It's now on my to do list.
 
Randy,

You could "unroll" the can to get to the inside. If the metal is soft aluminum it should be easy to slowly pry the edge and work a tool around the edge. I did the same thing with a Lucas flasher can and you can't tell it's been opened. IF the diaphram is basically sheet stock you can get good sheet material from McMaster Carr (Viton, Silicone, Santoprene, etc) but I bet it has more of a bellows or cup shape that would be hard to duplicate.

Cheers,
John
 
Okay, I'll give unrolling it a try; in the back of my mind, I know the milling machine is only a few feet away__I'll be be okay...

Now then, if I can just remember where I put that box of buttons and switches when we moved!
 
Randy,
You are great at the milling machine so far be it from me to dissuade you, but you can just carefully bend the lip back and then rebend on reassembly. I did it twice.

Okay, I managed to get it apart without using the mill, but sheesh, you call this rubber?!

Things started looking up though, and I got on with modernizing this fifty (50!) year old device.

First step was sizing an appropriate (former BMW shock absorber) washer to fit; wouldn't you know the outside was too big and the inside was too small. That's what lathes are for!

Making sure the can is nice and snug on the washer.

The pieces laid out for assembly.

A dab of silicone sealant; why I don't know.

The end result; it hardly looks molested at all!

So, while I'm at it, I might as well get the Longbridge style screen jet ready to go too. I was lucky enough to find the jet when going through some parts in the basement, but the inlet fitting had long since vanished. In fact, I don't even know what it was supposed to look like...

Spotting the end of a piece of stainless steel rod that I had already put some 1/4x28 threads on.

Then a 3/32" hole down through the (more or less) center. And the "tubing end" required turning down so the mounting nut could slip over.

Depth of the bore before I got too chicken to drill any deeper.

The end result, requiring only a fibre washer to go between the screen jet and the paint.

An overall look at the screen washer components for a Longbridge built BN4, or in this particular case, the actual components from BN6L-942.

Randy, being one of those folk around here who's skill level falls just a step or two below Anthony's musical skills, I'm blown away by your work. I'm sure the mechanics around here will have their sarcastic comments, but it looks incredible and I am beyond impressed with how good a job you did. And thanks for the pics.

Every time I see something like this I get all motivated to go out to the garage and try something new. Granted I screw it up the first 12 times, but I love seeing this stuff.
 
No Keoke,
It is beacuse I modified two canisters (Bugeye and 3000)not because I screwed one up! Looks like Randy got it though.

Randy,
Beautiful work. I am confused. I thought the style of washer systen you are working on was exclusive to first series BN4 Longbridge and VERY early (first 300) Abbington built 100-6 cars.

I guess as the 441st BN6, it qualifies as one of the earliest Abingdon built cars. I think the Trafalgar (sp?) was used until something like BN6-1182.

While on the subject, does anyone know what John Sims BN6 number is? https://www.healey6.com/index.htm I see that his car has a single/central squirter too.

Much drool at the great pictures of the unobtainable parts!!! At least I have the washer jar....

You know, I was looking through almost all the Healey books I have a couple nights ago, to see the washer jet and/or pump details; surprising few, btw.

But one of the ones I saw looked remarkably like a central post with a pair of jets (like the later, single jet type) coming out the sides at 90 degrees to each other__or 45 degrees off centerline. That looked like something somebody could turn out in their home shop, if pressed hard enough...

If you wanted to send me a pair of the standard jets, I could look into it for you. Disclaimer: no windshield washer jets will be harmed during the investigative process /ubbthreads/images/graemlins/wink.gif

I can already visualize what it would look like /ubbthreads/images/graemlins/cheers.gif

oops. I figured you wouldn't read this thread, it being all technical and such. But I shoulda figured you would like the pictures.
