Topic: Oil-bath air filter: 1950 Ford (6-cyl)


EWATERS    -- 06-11-2010 @ 1:10 PM
  I have trouble visualizing how the air-flow is filtered in an air-flow carb. filter. There is no diagram in my shop manual for my 1950 Ford. Does anyone have a diagram that shows the air filter and the oil reservoir functioning? Where is the oil stored? It doesn't seem that the brass/bronze mesh material on the top of the unit should be immersed. Any enlightenment will be appreciated; thank you.
Addendum: Is it feasible to use a common paper-filter element in lieu of the oil-bath? If so, how would I determine the correct filter to use?

  To answer your question, the oil pool is held below the mesh screen unit. There is usually an oil level indication on the body of the unit. Engine oil is placed in the body of the air cleaner, and the mesh unit is replaced and secured with a wing nut. The air cleaner works by directing the air flow over the surface of the oil, where the dirt is caught and falls to the bottom of the oil pool. Several years ago, we began to replace the oil with a modern filter. I am attaching the instruction sheet. The example was for my '47 Ford, but the principle for later vehicles is the same.

  I know this is not the diagram you are looking for, but I hope it gives you confidence that if you service the air cleaner as instructed it will work. If you do have the oil bath type cleaner the air travels down with some velocity and in theory the dirt and dust impacts the oil and is trapped there. The clean air is then deflected off the oil and funneled upward by the deflector towards the mesh, traveling thru the mesh and into the void occupied by the card intake. If the oil in the air cleaner is at the proper level the deflectors just touch the top of the oil. If any further questions feel free to e-mail me at bowlturner@astound.net

  Thanks for response; it looks like it's from the shop manual.
