How to tell if V8 Dist caps are on right? 1 Attachment(s)
On my '34 Ford, I believe my left and right spark plug caps are not in correctly. What's the trick to being sure they line up properly for the rotor to fire the plug contacts?
Thanks, Jim |
Re: How to tell if V8 Dist caps are on right? If you look closely inside the outer rim of each cap you will see a small tongue that aligns with a corresponding notch in the distributor body on each side. Insert the caps and rotate them until the notch aligns and you're there. When installed properly, the caps should have a slight tilt towards the rear and should fit snugly all the way around with no gaps.

Re: How to tell if V8 Dist caps are on right? The caps only go on one way. The plate where the plug wires connect have tabs along the outer perimeter which align the cap to the plate and the plate to the distributor base. You need to rotate the cap and plate assembly until the tabs engage. It's easier to do than to describe.

Re: How to tell if V8 Dist caps are on right? Different years have different caps with locating notches in different places.

I actually have a '37 distributor so I did my best to eyeball and be sure that both the caps fit & the rotor brush passes immediately next to the plug spike.
I wanted to ask how close the two brass contacts need to be. After lining it all up, I still can't get spark through to my plugs. Darned mystery. I have juice going into the dizzy and both the pigtail and carbon button are seated properly. WTF? |
Re: How to tell if V8 Dist caps are on right? If you look in the service bulletins, there is a test rig you can make using a model T coil, then its an easy task to test all the high tension stuff on the bench,

Re: How to tell if V8 Dist caps are on right? Mystery solved! Turns out the previous someone used the wrong caps which have the tooth in the wrong spot, a way different year. So, the correct ones are ordered and coming. My car would never have started and that's why my plugs were spanky clean- it never started for the previous owner as well.

Re: How to tell if V8 Dist caps are on right? Ford Spec. on the gap between rotor and inner cap contacts for 37 to be 0.0125 to 0.0065"
