Cam lobes & dist.badly worn on my TEA 20(lucas).What is the storey on the Pertronix set up i.e.will cam lobes effect installation...which system +earth or-earth...Do i require coil as i have new orig.coil.Intend ordering from this site Regards Brian [Reply]   [No Email]

The magnetic ring slips snuggly over the cam lobes and the cam serves no further purpose than to locate the magnetic ring. Sorry, I can't comment on the failure rate of Pertronix units as I've never had either of my units fail. I'm delighted with the improved engine performance. Never again will I have to fiddle with points and condensers. Brian, didn't realise you were in the Land of Oz. I have a fully reconditioned and serviceable distributor for your TEA20, if you need it. Bob in Oz '53 TEA20 This post was edited by Bob (Aust) at 03:14:56 02/06/10 2 times.   [Reply]   [No Email]

So the wear on the cam lobes does notgenerally effect the unit. A worn distributor bushing could possibly have a negative effect. Most Pertronix units are made for 12V negative ground electrical systems, however I believe some are 6V positive ground. Google Pertronix and check the website. you can use an existing coil as long as it matches the voltage the unit is designed for. You can also use a 6V coil with resistor on a 12V Pertronix BUT, as I recall,you must supply the the Pertronix module with 12V input connected upstream of the resistor, but don"t hold me to that. Your best bet is to look at the Pertronix webite and get your info there.   [Reply]   [No Email]

Rest assured it's WAY beyond what would be accepted in most other realms (atotyot's excepted)!   [Reply]   [No Email]

I figure I am money ahead because I spent no time adjusting points or dealing with other mechanical failures of the points system and I have a ranch to run so my time is worth something. The replacement module was $50 plus $10 shpg.   [Reply]   [No Email]

Worn cam lobes will have no effect on the Pertronix system. The gap between the cam lobes and the electronic unit is relatively wide and not critical, so a worn distributor bushing should not be an issue, although replacing the bushing is not a big job. The unit only takes a few minutes to install. I suggest you check, clean and lubricate the advance and retard governor weights whilst you are at it. Neg or Pos ground would be your preference, I don't believe it makes any difference. My TEA20 with Pertronix ignition is Negative ground for commonality with all my vehicles and incase I ever change to an alternator. I could look it up and check but I from memory the negative ground Pertronix unit for the TEA20 is an LU-145? Coil is your choice. I bought the Pertronix high voltage coil and set the spark plugs at 40 thou gap to improve performance. I am delighted with the Pertronix units. I have installed Pertronix in my Ferguson tractor and Jaguar XKE/E Type and both start easier, rev quicker and run smoother. I think the Jag fuel consumption also improved. Cleaning and setting points, tracking faulty condensers etc is a long forgotten bad memory. Two cautions - you could fry the unit if you reverse polarity and the black plastic ring unit that fits over the cam could break if handled roughly, so take care. I'm sure you will be impressed!

(I'm assuming you have a synchrograph to back up your statement???)   [Reply]   [No Email]

As I understand it, the magnet containing rotor slips snuggly over the cam lobes and the module senses the magnetic field from these magnets. The cam lobes are not use at all.   [Reply]   [No Email]
