Re: Adventures with a 1955 Clipper

Hello All,
This garage session is about sparking and pumping.
I removed, cleaned, and adjusted the gaps on the spark plugs. These are Champion N-16Y type. Note the long 3/4" threaded part and the projected electrode. This means my car is a later 1955 version as Packard changed the cylinder heads in mid-production from machined combustion chambers to cast ones and to the longer reach type spark plugs. I have not seen a set of N-type Champion spark plugs in probably 45 years. I have no idea how old these plugs are, but they appear to be in good operating shape.
In the day, spark plug metal shells were black. Later the makers changed to a bright metal finish. Bright finished spark plugs are not considered to be authentic in some judging circles. This car is not up to that judging standard, but I did color the plugs so they would resemble those available in 1955. I did this by coloring the shell with a black Sharpie. Some people use gun bluing. The plugs take on a nice color after being heat cycled a few times. The color is permanent. I like the looks, how about you?
Next I installed the fuel pump. It is an original equipment type Carter. I am so pleased to have a Carter carburetor and fuel pump as equipment on this engine. I also replaced the made up flex hose with a properly manufactured one sourced from Max Merritt.
Packard V-8s have a single fuel pump. That is, the pump only serves one function - to pump fuel. These Packards also came with vacuum windshield wipers. Packard uses a vacuum booster pump driven off of the bottom of the oil pump to keep the wipers from stalling when the engine does not produce enough vacuum. Some car brands use a double fuel pump - one that pumps fuel and provides a vacuum boost. Many Packard straight-8s used this type of pump. I am not sure about the flex hose positioning. It may have to be changed to clear the v-belt that drives the water pump and generator.
In the next shop session I will move to the top of the motor.
Take care.
