In trying to turn the oil pump, I have now removed the dizzy pedestal and
made a duplicate or the distributor shaft. I bought a piece of 1/2" round
aluminum stock. It was .003" wider than the shaft I had to copy. I used my
belt sander to bring it down to size. I then cleaned it up with emery cloth,
cut a flat tip on the end to go in the slot in the oil pump then cut down the
other end to fit in my electric drill. I used a cordless drill with a weak
battery. It was probably turning at about 400 RPM. Since the oil pump is
turned by the camshaft which turns at half the speed of the crankshaft, I
must have had the pump turning at an equivalent of 800 RPM or an idle speed.
The oil pressure gauge read 40 PSI. Not bad. After building up the oil
pressure, I hit the starter solenoid. The engine turns over good. Now I have
to put the spark plugs back in along with the distributor, water pump,
radiator and a few other parts.
