Pertronix - Pros & Cons - Video & Pics

Re: Petronix - Pros & Cons

The lifter was only out of place because of me pulling out the push rod. So there is no damage to it at all..
Here are some clean shots while I run out to get a close up of the rocker.

The inside is now immaculate. I can't go muc farther as I am missing a manifold stud & the fat washer that holds them in. The heatshield is also done as only about 1/4" of metal is holding it as 1 piece.
 
Re: Petronix - Pros & Cons

Here is the close up of that rocker. Small area in the lower right corner.

It was hitting the rim of the push rod. The push rod has a small marred portion of the edge but does not effect the where the adjusting screw sits.
 
Re: Petronix - Pros & Cons

Do the other rockers have a roll pin next to them to keep them off the pedestal?

Pardon my rookie ignorance, but what is a roll pin?
 
Re: Petronix - Pros & Cons

tiny round pin that goes through a hole in the rocker shaft to keep the rocker from slipping....do any of the others have such a gizmo - with a washer behind it next to the rocker?
 
Re: Petronix - Pros & Cons

Does not look like they do. The rocker next to it has side movement as well. It looks like if I lossened them all, they would have side to side motion. Nothing fixes these into place.
 
Re: Petronix - Pros & Cons

Then what probably happened to you is the same that happened to me...valve adjuster backed itself off & allowed the push rod to jump & the rocker to slide sideways.
 
Re: Petronix - Pros & Cons

Just a freak thing that happened to us and it should not happen again I hope?
 
Re: Petronix - Pros & Cons

Agree.
 
Re: Petronix - Pros & Cons

possibly. How's the valve spring? I was just thinking that a weak valve spring might allow something like this to happen... But I'm just guessing at possibilities too.
 
Re: Petronix - Pros & Cons

Dang you MG guys are sure wordy.

I apologize if this has already been mentioned but another downfall to Crane or Pertronix electronic ignition (not the Crane 3000 model) is if you chose to leave your ignition on in the run position for more than 2-3 minutes (without the engine running), the chances of your frying your module are extremely high. The Crane 3000 series ($$$) has electronic circuits to avoid this. I have fried 3 Cranes and 1 Pertronix until the manufacturers fessed up to this shortcoming.

I vote for points and condensor.

That said, you all must remember that I am just a Triumph guy and don't really understand most of what you are talking about.

Re: Petronix - Pros & Cons

The manufacturer of the pertronix did not need to fess up to anything. The FAQ of the installation instructions specificaly states; "A,This can cause your coil to overheat,which sometimes will cause permanet damage to the coil and the Ignitor". Been in there since year one.More Chinese Whispers.---Keoke
 
Re: Petronix - Pros & Cons

I never realized how hot the coil gets when you crank it over. While I was checking the compression, I happened to brush up agianst the coil and boy was it hot.
I should have a new heatsheild, studs & washers by Wednesday and will be able to re-assemble.
I have to think that it running reasonably well on 3 1/2" cyls will run even better on 4. I just hope the rocker does not decide to fall off again. I can't imagine what the solution to that one will be.
 
Re: Petronix - Pros & Cons

OH MY Gosh Yes Vping,They almost burn up. However, when you are playing around like that disconnect the coil.Better, get a remote starter switch and you will not require the ignition to be on to turn the engine over. The solution to the rocker is a big screwdriver and spanner.---Keoke-- /ubbthreads/images/graemlins/grin.gif

Yep, once I tightened mine back down, it never slipped again - & I had to do mine on the side of a country highway in Kansas in the summertime....took a long nap under a tree while the engine cooled down, fixed it & never looked back!

You will be truly amazed. I ran mine with a burnt valve for probably 3 months before I realized it and was driving every day to work and every weekend I was on extended runs. After I rebuilt the head I was dumbfounded by the acceleration.
 
Re: Petronix - Pros & Cons

I run the Crane XR-3000 in my own car, and its worked fine for 6 years now. Some day it will be replaced with a Pertronix unit.

No one has mentioned the "other" benefits of the Pertronix units! There is no more lateral force applied to the points plate pivot (caused by the points spring) once you install the Pertronix. That tension leads to wear on the pivot and can allow the dwell to vary dramatiaclly in an older distributor. Points cam wear is no longer a problem. Adjusting dwell is no longer a problem. Shaft runout in the distributor is no longer a problem - until it gets so bad that the rotor contacts the cap. It also tends to reduce the total distributor timing by about 2 degrees (change in dwell), which also helps to compensate for a worn older distributor. Starting the engine is easier as well.
I don't understand why anyone uses points! Its easy enough to have a "loaded" points plate in the car to install should the EI ever fail. And did I mention they have a 30 month no-questions warranty?
 
Re: Petronix - Pros & Cons

Hey, some of us are old school. I like as little electrical in my car as possible. Electrical tends to fail w/o warning. Mechanical will give you a warning. It's simple.
