Help with identification
[/IMG] 51duellerJust came from the garage where I took some pics of basically what you posted here.
I got a pic of the underside of the Breather, and the Donaldson MFG Label. So I will post these here, your post must have come in just before I went to take the pics.
Anyway this should clear things up as far as the understanding and I.D. of this Breather. Quite frankly I thought they were used in both the U.S., and Canada. Goes to show you learn something every day.
I still haven't heard anything back on another post iI placed regarding V.I.N. Tags being on the Cowl Centre under the hood. Jon Finn while your under your hood check to see if you have the V.I.N. Tag I am refering to. Maybe your Truck is Canadian built. the way I understand the U.S. built trucks didn't have this Tag.

These oil bath air cleaners have been around for years, and they are one of the best as far as cleaning the air that goes into your combustion chambers, they are further a flame arrester.
I have primed many times these old Flatheads, by loosenin of the wing nut and pouring a little gas down the carb, where that little indentation is at top of the breather.
I have never burnt one yet, it would take one hell of a flame to set that breather afire.
If you lift the top off you will see thet the oil is totally seperate from the throat of the carb.
Oil is a dirt magnate and this is the idea of the oil bath cleaner.
That material you are referinging to as horse hair is in fact no such thing. It is some kind of a fire retardant material, not Asbestos but another type.
You can clean these out with Varsol in a parts cleaning tank, blow most of it out with compressed air.
Then once dried you can spry a little oil on it, so it can do its job again. I have a 37 which is now 70 years old and it still has the original oil bath cleaner on it.
Show me a paper cartrige that will last that long. In some or most cases the material that you refered to as horse hair is in fact metal mesh.
Some what like the pot scrubers were made of.
Also the nice thing about it is this unit can be used over and over, its a life time filter, just needs cleaning once in awhile and change the oil.
The reason that they are probably not on the market today that I know of, is there is no money to be made from the use of them.
I have been useing these for years on the old cars/trucks, and as long as their around I will keep on useing them.
It's hard to beat it's filtering quality but it's just a bit more inconvenient for cleaning.
