Source for dizzy gear?

You can get reverse rotation engine distributor gears from aaamarine.com usually. They maintain a distributor gear stock of about 500.

Grant,
I sure agree with Gary and sure hope you picked up that Pertronix real cheap. Don't forget to factor in the gear you thought was expensive! When you make a purchase like this, I'd say it pays to ask here first.

This may explain why Pertronix does not find it necessary to provide RH rotation gears for their distributors:

ALSO -- as Ken informed me here, the shaft diameter differs from base diameter to diameter under gear. The new gear will be carefully fitted to the shaft, both diameter, and distance from shaft end. Thanks to all -- esp. Ken -- I've learned more than I thought I'd ever need, or want, to know about dizzy gears.

(J Pass is good at that) If not do a google search for   "Pertronix youtube Episode 34 part 1" and at about the 10 minute mark and several times after that you'll see good shots of a Pertronix advance mechanism in a 302 Ford distributor. Looks just like Grant's setup Don't forget, no matter the engine rotation, the distributor always turns CCW in these SBF's

Here you go KENO

Thanks again for all the help.
(I'll post this as soon as CCF is functioning again. It's not working at all for me as I write this.)

OF COURSE the dizzy rotates Counter Clockwise -- the same way I spun the oil pump to "prime" the oil system. duh!

I looked at the youtube showing the Pertronix Flame Thrower III, but did not see any rotation. No matter, just my comment saying I did view it. Also, not important, mine has the Flame Thrower II -- without the rev limiter.

I've now seem 100s of photos of the chain-driven cam in the 302.

The Sierra gear appears to be a good one, maybe the best for me.

Wish I could see all the recent comments. I'll look at them when I'm back on CC Fan.

BTW, it might interest you to know I phoned the tech line at Pertronix 3 times in the past week. At first, looking for the gear I need. The gear they do not make, nor sell. Each time I asked: "Looking at it from the top, which way does your distributor turn on a "right-hand" Ford 302?" Not a one of the three could answer.

Yes, I know it was downright stupid of me to can my old distributor. (I've promised to free up one of 3 garage bays for my wife's car. Pitching old motor stuff was part of that effort.)

   

Doughtful there is a distributor that turns opposite,there would then be a need for a reverse rotation oil pump then

As for as the weights,you could stick the shaft in a 1/2 inch reversible drill and see which way makes the weights get flung outwards

Then you'll know for sure

Am I missing something here? To me it appears the dizzy should turn CW in order to push the heads of weights outwards.

I know it's automotive and a GM, but in this vid it shows a CW dizzy rotation swinging the weights, not CCW.

Go to the 6:00 minute mark to see what I'm referring to:

That's what I thought, but was convinced otherwise.

Hi Grant

It looks to me like the flyweights get thrown outwards when the distributor is rotating counterclockwise.

That would be right for a Ford.

I think you just need a gear.

Grant,
It looks like you've already spent plenty so what's another $80 for a gear?
