PINGING: TIMING: Thanks, JW. I did retard one notch and took it for a short test run. No pinging. However, I still need to run it on the freeway and push it beyond 65 to be sure.
ELECTRICAL GENERATOR In the meantime, I pulled the generator which did not pull the ammeter out of discharge with the headlights on when I rev'd the engine.
I had to undo the bolts in the bracket from underneath. I pulled it out from above after piling up some towels on the fender protector. The bracket measures 6-3/8th in. OD.
The generator is a GGU-something. The only listings I found for GGU were for Chryslers. The bolts are 5/16ths. There were some spacers used. It measures 8-1/8th OD. This generator is obviously not the original and did not come from a 120 engine I had. It could have come from a 1950 custom with a 1947 engine or from some kindly mechanic.
The replacement I have is smaller. GDZ-4805-A. It could have come from the 120 engine or the 47 356, but the only exact listing I had for it was for a '41-'49 Studebaker. It was once in the car, also. It looks like more in size like photos of generators here, like this one posted by JW.
I have read most of the threads on generators and fan belts.
When I looked down at the bracket, there is a flange that juts out from a metal plate on the front of the engine. It has a hole in it that lines up with the bracket. The ear of the replacement generator seems to want to go between the flange and the bracket when the rear ear in on the outside of the bracket.
I was able to get the rear bolt in place, but the front won't line up. Believe I tried everything. The will only go about half way to where it should be. So I took the generator out.
In reading the generator / belt threads, I came across a mechanical drawing for a later model. It appears the flange and the bracket are together on this set up, and both ears bolt to the front sides of the bracket.
I'm thinking of putting a bolt through the flange and the bracket and then trying to spread them apart a little more so the ear would sit in there. I'm thinking it's possible that the front fastening arrangement needed for the larger generator squeezed the flange closer to the bracket than it should be.
I spent an entire evening with every manner of poker to try to line up the front holes, but the ear wouldn't go down any further. I even put the old generator on top to keep pressure on while I worked the alignment underneath.
I could use some sage advice. If I thought the larger generator were correct for the car as much as I think the smaller GDZ is correct, I would take it back to be rebuilt at Philbin and not bother with the replacement.
