MG TD TF 1500 - Plug Wires

Would anyone happen to have the length of the four plug wires and the coil wire for the TD engine?
Bill Reid TD4618

Hi ..... 1080 mm exactly.
IW Martin

From front to rear : 36 cm, 30 cm, 25 cm and 33 cm
The one from the distributor to the coil is 30 cm.
These are not original. I cut the correct length myself to fit the car. Take care of the distributor type and orientation.

However, I believe that those parameters are compliant with original on my car.

LC, thanks for the plug lead lengths.

What is the orientation if your distributor cap? My #1 connection is at 10:30 o’clock..

Peter. It depends on where the distributor drive gear is when it was put into the engine. My number 1 is at 9 o'clock. You can change it by putting the motor at TDC and pulling the distributor. Then move the rotor. As long as the number 1 wire is over the rotor, you are good.

Bruce Cunha

Understood, that is why I was asking LC, he had specific lengths, but it does depend on where #1 is to be valid.

Not really -just put the longest wire on the farthest-away distributor terminal, and the others will all fit.

I also have a pair of "virgin," low-mileage engines here, and will measure those wires.

Another position setter - Some folks set their distributor so that the 12v terminal is NOT at the 8 o'clock position. This is to assure that a loose tachometer gearbox won't short out the distributor.

Never answered ! I apologise for it.

Here is a picture of my setting with those wire length.

In my notes, I can read that Clausager shows a different position than the WSM. I never had the Clausager but probably I could have a look at it at that time.
I also noted that I selected the Clausager setting.
The point terminal is far from the speedo gearbox.

Thanks Laurent
