Windscreen Washer

First a description of what was:

My 1964 Jaguar Mk2 did not have the original Lucas Screenjet washer bottle and pump. I don’t know why it was missing. Perhaps a pump motor failure or a broken reservoir? Lucas actually put glass reservoirs under the bonnet. This is an image from Eric Kriss’s MK2 of the original equipment that should have been in my car:

Note that on the original Lucas washers there were three electrical leads:

Lucas Washer Electrical Terminals

Restorer’s can purchase new replicas of the original that do look the part, but the new pumps have only two electrical terminals:

New Lucas Pump

While today’s replica is not perfect, it sure beats what I found in my car: nothing! This photo illustrates the proper location of the Lucas Screenjet. 

Lucas Screenjet Washer/Pump Location

Two captive nuts are provided in the LH engine bay valance for securing the washer bracket to the car.

Mounting Point for Lucas Screenjet Washer/Pump

Now a description of what is:

I cannot locate a washer reservoir in the original position because that space is now at least partially occupied by the air conditioner compressor. I also cannot relocate the washer to the space on the valance rearward of the fuse panel because I have mounted my power steering pump at that location. So I gave up on mounting the washer reservoir/pump in the engine bay. 

After considering several options, to keep things “Jaguar” I elected to use a later plastic reservoir and pump used on XKEs and perhaps some later MK2s – I am not sure. I sourced the pump and its mounting bracket from Welsh Enterprises.

I decided to locate the pump and reservoir at the front of the LH wheel well on a chassis bracket. I mounted it to the same crossmember that is used to mount the reservac tank on the RH side of the car. Because the crossmember comes from the factory with two pre-drilled holes to mount the reservac tank for RH drive cars, I was once again able to mount a modification without having to drill new holes in the car!

I picked up a stainless “L” bracket from my local ACE Hardware store made from 1/4″ stock and mounted it to the Lucas supplied bracket using two 1/4″ – 28 x 5/8″ stainless hex bolts with flat and split washers and nuts.

I then mounted the bracket assembly to the chassis using two stainless 1/4″ – 20 flat head screws with flat and split washers.

The clear tubing goes through a rubber grommet in the valance and is routed through the firewall to a “T” fitting where it branches to the LH and RH spray nozzles for the windscreen. A ground wire connects the pump motor to a fastener on the diagonal chassis rail and can be seen in the image above. The + wiring (light green/black) for power is encased in a rubber sleeve and also goes through a rubber grommet and is routed through the firewall to the central gauge panel switch for the washer activation.

Dash Fascia and Gauges

When we bought the Bugeye, it came with a working tachometer and a dead speedometer. After thinking about having the original instruments refurbished or buying new ones I decided to buy new Smith’s gauges. Keeping the original tach would have involved installing the guts of an electric tach into the casing of the old gauge since we had previously installed an alternator making the original worthless since it had a mechanical drive off the back of the dynamo.

So the new gauges were ordered from APT Instruments, but it would be terrible to install them in the old dash so replacing old vinyl with new naugahyde was the only thing to do! I began the removal of the dash and proceeded slowly, carefully labeling the wiring to each instrument or switch.

I initially disconnected 2 orange/yellow braided wires to the wiper washer pump. Using a micro switch, my dad had previously converted the manual pump for the windscreen washer to an electric pump. Next was the heater switch. I disconnected a green/brown wire from the harness from a black wire to the heater switch. Then I disconnected a black wire from the heater switch body from a double bullet connector into a light green wire.

The turn signal wiring was next. The switch has three spade connectors. On the side with tow spades, a yellow wire attached to one and a blue wire to the other. A white wire was disconnected from the side of the switch with the single spade.

The Ignition Switch followed. The switch had four screw terminals. The top right terminal had 2 red wires joined together. The top left terminal had 1 heavy gauge yellow wire. The bottom right terminal had two white wires joined together and an red fused wire from the the electric fan switch that had been added. Finally, a large blue wire was disconnected the bottom left terminal. A previous owner had fabricated a clamping system to hold the ignition switch in place, that while primitive, did work. It will be replaced later.

Gauge Lights. Wiring for most gauges is red. The oil/water temperature gauge light fit into the retaining bracket sleeve. The tach light was also red, but this wire was ultimately discarded as it was not needed for the lighting for the new tach.

The panel lamp switch had three wires. Two red/white wires were joined and connected to the right terminal and 1 red wire was disconnected from the left terminal.

Has three wires: the black ground wire was removed from the top spade terminal, the blue power wire from the switch to the fan itself was removed from the middle spade and the red wire with fuse to the ignition was also disconnected.

The Horn

Had one brown wire from the horn trim ring to the horn itself. The wire was disconnected at the bullet connector.

After removing the starter button and cable, the choke cable and the heater air control assembly cable, and the grab handle, the dash was removed from the car. Two ¼” hex head bolts secured the dash to the body on the left and right side. Two chrome phillips head screws fastened through two brackets from the firewall to the dash and finally one nut is fastened to a stud located centrally at the top of the dash.

Recovered Dash

Then it was time to recover the dash. I purchased some naugahyde at a local fabrics store and some contact cement and went to work. This is the result:

The new tach and speedometer

While not original design, the new tach certainly looks period. The tach required some new electrical connections.  One wire connected to the coil, another to the fused power block and one to ground. These are the installation instructions:Electronic Tachometer Installation Instructions

Demister Hoses

The old paper demister hoses had holes in them and obviously did not work well. With the dash off it was the perfect time to install some new hoses.

Aluminum Racing Pedals

My dad had installed racing pedals in the Big Healey and thought they did give a better pedal feel in addition to looking cool, so I bought a set for the Bugeye as well. They do look nice. I did not use the racing pedal for the accelerator pedal as it was just too close to the brake.

Electric Windscreen Washer Pump

Electric windscreen washer

My dad read a technical article by Stu Brennan, an owner of a Sunbeam Tiger, who had converted his hand activated pump windscreen washer to an electric washer. He liked the idea because he put the electric switch in the aluminum pump canister thereby eliminating the need to install an additional switch somewhere. Since the washer in the Tiger is the same as the one in both the Big Healey and the Bugeye he decided to give it a try.

Two items needed to be purchased for the conversion. An electric pump typically used on later Sprites was ordered from Moss Motors.  A Home Depot switch was purchased, Gardner-Bender, Push Button, GSW-22, SPST always-off.

The old pump was easily disassembled by un-crimping the lip from around the plastic bottom. The metal is relatively soft, so it unfolds easily. The bottom and the old rubber bellows came right out, leaving only the plunger within the shell of the pump.

To provide enough depth for the switch in the canister a slot was cut in the plastic face plate. The slot also provided space for the switch wires to exit the canister. To provide stability for the switch in the canister and to use as a spacer a circle washer was cut of 1/4” wide plywood that fit tightly in the canister and placed it on the switch secured with double nuts.

Power comes from a switched terminal on the ignition switch, and is connected to the new red wiring through an in-line fuse holder. From the other side of the switch, a new red wire carries power to the white wire on the pump. The “negative“ side – black wire –  of the pump is grounded at the mounting bracket.

The pump was secured to the left side of the firewall and the appropriate hoses were connected to the water supply tank, the pump and the two jets.
