TR2/3/3A TR3 Windshield washer pump

[TFB]

My post 6k TR3 body has windshield washer nozzles,and I got what looks to be a stock plunger pump with project.My dash has no hole for mounting pump.
If I decide to drill and mount ,where was this pump originaly mounted?
Thanks
Tom

I think there are a couple of options. It is my understanding that most of the washers were dealer installed and I'm not sure that ST provided directions or templates for pump mounting. Perhaps someone knows where ST placed the pump at the factory, if in fact they did. Mine was mounted on a bracket that was screwed to the flange on the bottom edge of the dash panel below and just outboard of the tach. I'm quite sure mine came that way from the dealer. However, several others (most?) have them in a new hole in the dash face, beside, or in place of, the OD switch.

I can't answer for what the factory did, but the washer pump on TS39781LO was in exactly the same spot shown on TeriAnn's website:

I've seen a couple of examples where the location is shown as in Randall's picture. And while we are on this topic, if anyone knows where I can get a knob just like the one in that picture, please let me know! I've looked for a while and have had no luck so far.

Thanks for replies and pic.My pump must be later,with a generic windshield and wiper label,and the retaining nut that holds it together doesnt look like its meant for through dash mount.I may have to make a braket or find a different pump.
Thanks again
Tom

Yes, I'd have to agree (after a quick Google search). The few pics that I found show it in the exact same place. There may also be a picture of an early one in Piggott's book (p 38) on a RHD car. It's on the opposite side. Tom

Hi Tom,

One more pic for you. Mine was installed on the left of the wheel just under the heater knob.

And from the back side

Cheers,
David

Thanks for the pic David.

Those car built before the electric pump was invented?

Don,
Lots of cars had period electric pumps (aftermarket?) also, with switch in place of pump. Still do.

Not a matter of invention, (electric washers were available even from Lucas) but rather cost I think. Remember, these were "budget" sports cars, built to a price point well below most contemporaries. And electrical components in particular tended to be more expensive then (comparatively speaking), especially since Lucas had effectively a monopoly on the British market.

Besides, the manual pump was simple, lightweight, and effective.

C'mon Don. The generator barely kept up with lights, heater and wiper motors all going. You want it to power an electric washer pump too?? TR4A's still had this same pump (actually the one in David's looks like a TR4/Spitfire one especially given the knob style).

I think the TR250 was the first with an electric pump on the washers.

Yea, what was I thinking

I had jets in place on my '59, but nothing else. I wanted to get 'em working, so I bought a reservoir and a universal electric pump and rigged it all up. The pump provided so much more pressure than the hand pump, that it shot the blue liquid clear over the winsdhield, onto the boot. Not a drop ON the windshield. I found pair of aimable jets on eBay for cheap, and put those in. Now it all works right.

When I ordered my 1958 TR3A brand new, I paid an extra $15.00 for the windscreen washer option. The factory had already installed the nozzles on all TRs up to then but the S-T dealer here in Montreal where I bought the car installed the washer bottle, the plunger and the tubing. It was by Trafalgar and he installed the knob to the left on the dashboard near the overdrive switch ($150.00 extra for the O/D option). TRA judges docked me a point in 1992 because the blueprints they had received from England (drawn by an English Draughtsman in Coventry and who drove a RH drive car himself had drawn the drawing with the plunger on the dashboard for the convenience of all who drive RH drive TRs) showed it over near the cubby box. I believe that anyone who ordered his TR3 or TR3A with this option "factory-installed" received the TR with it in the position shown in the photo from Randall.

I believe that TRA have since stopped docking a point for the position of the plunger and knob since it could have been "dealer-installed".
