I hadn't seen one of these before. A poor idea I imagine. Does anyone know when or how long they were used? The valve and outlet are both cast iron, not brass. (Magnetic)
I'm betting that takes more than a little heat up and water quench to get apart.
if you get it complete red and dunk in water fast it will come apart buy hand and not crack.charley
I see there is an iron pipe plug in the bottom instead of a petcock. Could this be an early version? I will place it in a container of ATF and lacquer thinner. Maybe after a couple of years it will free up.
I had an all cast iron sediment bulb in my parts collection that I removed from a gas tank. It was in very good condition.
I'm pretty sure it was aftermarket. It looked nearly identical to a Ford bulb but it was slightly larger and had a substantially huskier handle.
My '19 had one when I got it. Are most of them brass?
Ok. Thanks Mark.
Richard- I removed one from an old tank last week with the iron valve and a pipe plug rather than a petcock in the bottom BUT it did have the brass outlet fitting. Dan
The encyclopedia in Mark's link doesn't address the cast iron valve and outlet. On cast iron bulbs, these items were still bronze. At least every one I've ever seen until Richard posted this photo. I'm wondering if Erik isn't onto something with the aftermarket idea?
Hal is correct. I bought a cast iron bulb at Hershey this year, it had a bronze valve and outlet.
One thing I noticed when I took it apart for cleaning, it did not have the extension inside to ensure that sediment didn't just go straight across to the outlet screen, see pic below.
Also shown is a drawing I found on another thread of a bulb cross section with the inside extension feature (pointed out by the arrow).
I wonder if any production bulbs actually have the extension feature? What about the brass bulbs currently available from the vendors, has anyone taken one apart and seen whether it has the extension feature or not?
I have one in my hand now, ford script, no extension. Interesting. KGB
I have a few of the 1915-1925 cast iron bulbs. They all have bronze valves and outlets. I haven't opened them up, so I don't know about the extension.
I've seen a few of the kind with the cast iron valve. I assumed they were made during The Great War when brass was needed to kill Germans. I also assumed the cast iron carb inlet fittings were made in this same time period for the same reason. No proof, just speculation.
A little tip for disassembly - my bronze valve with the long handle was stuck fast in the cast iron bulb body. I removed the cotter pin, washer and spring, then soaked the valve for a couple of hours with penetrating oil and rooted around for a 1/4 inch deep socket that would fit over the end of the valve. Once I found one that was a good fit, I used it to punch the valve out without having to turn the handle and risk breaking it off. Then, I used toothpaste to lap in the valve after cleaning everything up.
Ford changed from the Brass sediment bulb in 1916 to the cast iron version. I've never seen an outlet that was cast iron. Interesting! I would replace the one you have with another. They show up on ebay a lot.
Larry you made me look again at the ford script one I have here and it has a cast iron outlet, who knows though what could have been changed in 90 years. KGB
The outlets on the earliest sediment bulbs were rather flat with no script. The later ones are rounded around the edge, and have a Ford script and a part number.
