Magnetic Drain Plugs

Magnetic engine oil drain plugs were not an option on any English Ford vehicle, to at least, up to the 1970's.
I've seen a few automatic transmissions that had a prolonged small iron magnet pressed into a drain plug but these are very weak compared to a new style magnet.

Attach a "rare earth magnet" ( Neodymium-Iron-Boron ) size: 3/8 x 1/8 to the threaded end of a drain plug by either drilling a 3/8" hole, approx. 1/8" deep for an Anglia 105E  3/4" x 24 plug type or epoxy to the end of a 1/2" x 20 plug i.e. Cortina MK2.

Once installed, this will allow you to observe any ferrous metal particles in the engine oil after an oil change.
Too much metal attached to the magnetic may indicate a problem with i.e. the camshaft lobes.

Manual transmissions have a cup-style drain plug to trap metal particles which are mostly syncro ring brass particles. By the way, the flat-end fill plug should not be installed as a drain plug.
Add a "rare earth magnet" or remove the old iron magnet on the drain plug for an Automatic Transmission.
Some of these transmissions had a iron slug magnet welded to the inner bottom of the pan which should be left in place.

Positive-Ground Systems.

The transition to negative ground came around the mid-1950's for American cars, 1967 for English Fords and around 1971 for all other English cars. The preference to use - or + ground didn't matter much. The standardization to negative ground in the Auto industry was only because of the introduction of negative ground electronic gadgets.

If you already converted the car from + to - ground, do not use the original Lucas coil marked CB and SW even though you reversed the two wires on the coil. Purchase a new coil made for negative ground systems. It should read + on one side and - on the other side of the coil.

Here's why:

Primary & Secondary Circuits on a CB / SW positive ground Coil:

When the engine is running, each time the points open, the current stops flowing and the magnetic field collapses around the primary. The secondary has approximately, 20,000 turns of fine wire ( 100 to 1 wire wound ratio secondary to primary ). The collapsing magnetic field will induce a voltage of + 22,000 volts at the core for the spark plugs.
Auto-Transformer action: In a coil the secondary and primary windings are in series.  If the wires to CB and SW were reversed then the current will flow in the opposite direction and will defeat the purpose of an auto-transformer effect. The arc-over voltage output of the coil would be approximately 10% less . It is spark current that ignites gasoline. Obviously, if you don't achieve arc-over voltage, no spark current will flow.
In other words, there is approximately 10% reduction of voltage required to jump a spark plug gap. If the car is converted to a negative ground and a negative ground coil isn't installed then the 10% voltage advantage is gone.

105E / 113E / 118E Transmission Back-up light Switch




 This procedure is done with the transmission removed from the car and reverse selector rod removed from the transmission. It's not necessary to completely dismantle the transmission for this step.

Anglia 105E, Classic / Capri, and Cortina MK1 models have a manual activated toggle switch located on the lower end of the shelf as standard or optional equip. After 1967 the back-up light switch were mounted on top of the transmission casing activated by the reverse selector rod.
Any early transmission casings can easily be modified to an automatic back-up light system. By using a reverse switch from the Cortina MK2 or any universal 3/8 x 24 ( 1" long shaft length ) similar switch.

Drill a proper diameter hole directly above the reverse selector rod transmission casing, as pictured, for a 3/8" x 24 tap. Grind a 1.63" end section off the selector rod to create a 9/32" wide flat surface. Then grind a 5/16" long, approx. 20 degree slope at the end of the selector rod for a switch step-up.

Insert the rod in the casing and mount the back-up light switch. Adjust the switch so it will turn on-off ( an ohm meter will do ) while moving the reverse rod. Assemble the transmission for re-installation and mount the switch to the casing. Engage the stick shift in reverse to check activation. Leave the switch installed as it will not interfere with transmission installation.

English Ford Transmission Selector Forks

Worn selector forks or syncro-mesh assemblies can cause the engaged gear to jump out of its position when decelerating.
Assuming all transmission components are in good condition but the selector fork facing on both sides are worn down to 5/32" thick ( new fork facings are 1/4" thick ). This excessive play within the sleeve groove
can cause the transmission to jump out of gear.
One solution is to fill the worn area of each side of the fork by weld brazing up to 1" in length and grind smooth and form to a thickness of 1/4". Do not repair forks that are worn beyond 5/32" thickness. New forks are still available i.e., Burton Ltd.
Displayed are two 113E bronze/aluminum forks from the Cortina MK1. On the left is a worn repairable fork and on the right a reconditioned fork after weld filling and finish grinding.
I have reconditioned steel forks for Anglia 105E transmissions and brass forks for the 113E - 2000E three-rail box and later single-rail Cortina MK2 box. I found that all selector forks for these boxes have a face diameter / thickness of 1/4". Reverse selector forks don't have much wear.

Canister Type Oil Pressure Senders

These senders are on the Cortina GT 10/64 > 9/66. Ford p/n : C5EH-9D290B or C9EH-9D290A. 
80 psi ( stamped near the brass base ).

Function:

The oil gauge has 5 volts applied from the voltage stabilizer to one terminal the other terminal connects to the sender which acts as a variable resistor to ground.
64-66 Cortina MK1 GT Oil Sender Unit
Canister plus spring loaded plunger base cut off to expose circuitry and diaphragm

Completely disassembled unit.

As the motor is running, engine oil enters the sender and pushes against a rubber diaphragm in turn forces a spring loaded plunger to move a sweeper arm across a wire wound variable 80 - 0 ohm resistor. Oil pressure causes the 80 ohm resistor to decrease in value thus the oil gauge needle will move towards the right.
It is possible to refurbish these sender units by carefully cutting off the canister body midway around with a hack saw ( I've destroyed my sender to remove all the parts of the unit ) This will expose the internal circuitry for cleaning and damage. Oil inside the canister is an indication of a ruptured diaphram at that point the unit is unserviceable.
Carefully clean the sweeper contact, wire wound resistor and arm contact to the threaded stud. Connnect an ohm meter across the resistor, it should read approx. 80 ohms. With the ohm meter still attached across the resistor, move the plunger arm slowly so that the sweeper moves across the resistor. Resistance will decrease from 80 ohms to approx. 0 ohms without hesitation. Thus 80 ohms = 0 psi and 0 ohms = 80 psi.
Realistically the resistor should read around the 40 ohms for 40 psi. as the car is running at speed. If it works properly, the canister can be soldered back on the unit with 50/50 type solder. Don't use a torch.

Replacement senders:

Ford/Lincoln/Mercury 1960 - 80 canister senders 1/8" x 27 NPT ( for a 1/4" hole size ) approx. 80-90 psi
with a terminal button is close enough and should work.

Rotary Star Door Latches



Figure 1
Figure 2
Figure 3
The rotary star mechanisms should be in good shape before starting this project. This work can be carried out on other similar English Ford latches.
Figure 4

Figure 5
Figure 1 is a worn, early Anglia 105E door latch.
After removing the arm spring, drill out the lever arm stud rivet just enough so that the washer will come off. Remove the two levers and spring washer. Turn over the latch and file down flush the stud rivet which now can be pulled out of the latch base plate.




Figure 4.  I've removed the arm from the worn lever on the left and welded it to the fabricated lever on the right. It was easier to make a new lever from the same material and thickness and cut off the lever arm off near the base of the worn lever with a hack saw and weld it to the new lever. Take care to attach the arm at the same angle and height as the original part.





Figure 5.  I chose to install a shoulder bolt and flush nut insert ( fig. 3 ) to hold the levers in place. Added epoxy on the bolt threads and filed down the nut a bit to make it more flush. The nut should be just tight enough to allow the levers to move freely by the return spring.
Another way would be to weld the thread of the shoulder bolt to the base and then file off excess weld.
  
Oil the star rotary bushing and movement levers and grease the lever wheel. Brush a coat of grease on the whole inside latch to prevent rust. If the spring is broken replace it with a similar tension spring. Squeeze the end of the springs to prevent the spring from coming loose.


Figure 2 is a rebuilt door latch.

Dove Tail Door Striker Plates

" A door is only as good as it's lock". Strike plates or door strikes are the protective metal plates installed in the door jam that receives the latch or lock tongue when the door is closed. The ones in issue are the dove tail striker plates incorporating an aggressive toothed pattern on the bottom of the plate. This type is used on the Anglia 105E/123E, Consul, Zephyr, Zodiac and more. As English Fords from the 50's/60's continue to age, I'm seeing striker plate teeth wearing to a point of  safety concern. In those conditions the door needs to be slammed hard to close properly. In that case a new replacement is necessary. I've contacted many sources regarding the availability for new plates with no avail. So I decided to give it a try and repair the most promising plates. Note: To start with,  door latches need to be in good condition


Figure 1 and 3 plates are in good enough condition for repair. Figure 2 cannot be used for this type of repair. These are worn beyond a point of safety and the door will be in danger of flying open whilst the car is being driven at speed.

I've had success with using J-B weld epoxy. After rough sanding the worn area apply epoxy to plates to Fig 1 and Fig 3. Fill the cavity over flush in Fig 6. After the epoxy is dry file down until flush Fig 7. The epoxy filling is still holding to the plate tooth pattern on my Anglia 124E after a few months with little wear showing at the same time preventing any further wear on the tooth pattern. The filing may one day fall off but I'll just re-apply a new batch.

The Anglia 105E/123E sedan came with two styles of striker plates Fig 8: early type < 10/1962 and Fig 3 later type > 10/1962. Estate later > 6/1963. Fig. 4 are the early types. The L/H plate tooth pattern are solid while the R/H has a hollow front tooth. Fig 5 is the later type all hollow tooth. Be aware of these hollow tooth plates esp. if worn completely through the casting. REPLACE THEM.

Fig 8 are restored early type striker plates with new bumper rubber. Be sure that the door lock striker safety plate is installed p/n: E2093-AA-1 on both early and later striker plates.

Refurbishing Steel Master Cylinder Reservoir Caps

I've had success refurbishing rusted English Ford steel reservoir caps with solder.

Refurbished Reservoir Cap
These should be sand blasted first to get rid of the rust and to observe the condition is void of any major dents and holes. It also preps the cap for solder.

Use a propane torch and 50/50 solder ( lead/tin ) used for repairing copper radiators.

Clean the steel cap with acid flux. Heat the cap hot enough so solder will flow once it's touched to the cap. Careful not to over heat the cap. Once the cap is covered completely with a thin coat of solder including the threads but not the inside, re-heat the cap and wipe with a cotton cloth to smooth or a small tooth brush size wire brush. Then use a bit of metal polish. It may take a bit of practice but the outcome is worthwhile.  This will not prevent the cap from rusting so it would help to wipe it with WD-40 once a month or sooner.  Make sure the vent hole is still open.

Aluminum caps that incorporate an inner steel insert can be cleaned with a small metal brush to remove the rust and wiped clean with a cotton cloth and a bit of WD-40.

Rear Brake Shoe Spacers

There should be a rear brake shoe spacer for the Cortina/Lotus/Corsair MK1 GT ( 10/65>) , all Cortina MK2 and EnFos of that era that incorp. the auto. adj. wheel for the b/shoes. Without it the handbrake comes out too far even after tightening the H/brake cable also the lever won't turn the auto. adj. wheel properly. Sometimes these spacers were not reinstalled after replacing the shoes.

P/N: DORY-2028A for the Cortina MK2. and P/N: 2925E-2K466A for the
Cortina/Lotus/Corsair (10/65>) which is not listed in the parts book.

I've reproduced spacers from the original part if anyone has them missing.

Tips on choosing the right electric fuel pump for your English Ford

There are plenty of good reasons for installing an electric fuel pump but choosing the proper one is very important and here's why:

At full-open throttle a motor requires about 1/2 lbs fuel every hour per h.p. A gallon of gasoline weights approx. 6 lbs. So if your engine makes 50 h.p. it will need a pump that supplies fuel at 8 gph. ( 50 x 1/2 ) = 25 lbs per hour then 25 divided by 6 = 8.1 gph.
An Anglia 100E/105E needs only 1.25 - 2.0 per sq inch of fuel pressure for its Solex carb to function properly.
Cortina 1200 / 1500 / 1600 requires 1.25 - 2.5 psi.
Cortina GT / Lotus ; 2.75 - 4.25 psi.
Any more than 8 psi can flood the carb. Installing an electric fuel pump of 150 gph @ 6-8 psi will need a fuel regulator to reduce the psi.
Since pressure ( psi ) and volume ( gph ) are inversely proportional "real world" flow rates will vary depending on driving conditions.
For Authenticity and preventive maintenance the original fuel pump can be left on and an in-line electric pump can be installed near the fuel tank with an on/off switch.
