Default Re: Distributor drive gear

They have me hopped on opioids and nerve meds and they kind of screw me up. I'm little out of it half of the time half of the time. Sometimes I think I see what I expect to see.

This is the original Merc cam that came out of that engine on the stand in the photos above It was reground into Potvin Super 3/8. With the first lobe pointing up I stuck a bolt in the closest cam gear bolt hole. I rolled it over and you can see that the bolt falls between two teeth. But then I noticed the alignment marks on the gear and cam are slightly off. Are they Ford marks or the cam grinders marks? Because I got to thinking maybe that gear needs to be removed to chuck the cam up in the cam grinder. Since they are off a little that means the bolt centered between the teeth would be off a little too. If they are the cam grinders marks that means he thought the gear needed to be put back in the original spot as your thinking. So, I went back out to the flathead junkyard to find an unmolested cam. It would be nice to have one the gear has never been off of. I found six early cams but no late model one's with gears. It would be nice to check a couple originals to see if the bolt lines up in the same spot, but this is the best I can do.
