Dirt Daily. The Flatfender gets an Oil Bath Air Cleaner
Вставка
- Опубліковано 15 жов 2024
- Engines like clean cool air, and the 1946 Willys CJ2A is getting a factory style oil bath air cleaner to cut the trail dust. This is an interesting system that uses oil and a steel mesh to trap dirt during your next off road adventure. Modern engines have moved on from this technology, but I wanted to try it out and see how it works. Plus why change it if it works?! (ha! I never say that, I love changing stuff)

Hahahaha hahahaha pulled air or smoke backwards through water😵💫
Lol that hesitation to explain filtration, priceless
Listening to you say the filter works like a bong, without saying it works like a bong was the highlight of my day.
You inspired me to get a flat fender, so in true fashion I got a free one that has been in the briars since 1979, wish me luck! (1942 CJ2A)
Best of luck sir. I hope you project goes smooth and drives beautifully when finished. May God Bless you and your family.
good luck!
Wait... Isn't the CJ2A a post war variant?
I see Fred. I press like
It doesn't really "bubble", the air is forced to make a hard 180-degree turn. When this happens, the air turns fairly easily, but the heavier particles in the air like dirt and dust tend to continue to travel in a straight line and get attached to the oil Bath and eventually sink to the bottom.
Some oil does work its way into the mesh filter element, which then works as a second layer of defense to help catch particles that made it past the 180-degree bend. As the oil drains out of the mesh, it carries particles with it back into the oil bath.
Engine air particle separators for helicopters make use of a similar idea. By making the air make hard turns, you lose some efficiency, but you separate out the heavier particles. Making physics work for us.
Absolutely right. Centrifugal force slings the particles to the outside of the 180* turn and is stuck in the oil where it eventually settles to the bottom. ..
thanks! that makes lots of sense
Wouldn’t the oil bath also act as a water capture? So any water in the system would sit under the oil pushing the level up until it chokes the air off from the engine?
Can’t beat an oil bath air cleaner for actual use in dusty areas. My old M37 that I grew up in, never saw pavement. Drove all summer on unbelievably dusty logging roads, only needed to clean it once a year. The amount of filth in the bottom was amazing. The best part was, it didn’t get choked up as it accumulated dirt. When I got a Toyota pickup with a modern paper element, I had to change the element at least three times a year, with multiple shake outs in between. I got a K&N, and had to wash the blasted thing every week. You could feel the little 22RE losing power, as the filter clogged.
One of those technologies that I see no need to replace, works a charm especially in this application, great info Fred
I've cleaned those filters when I was young. In 1985 I got my new gas powered air compressor. The Honda gas engine still has that oil bath air filter on it. Just clean it from time to time and it keeps going.
My parents had a 53 Chevy 6 cylinder and it had an oil bath cleaner.
Thanks Fred for this video. Great memories with older vehicles and equipment.
The amount of effort you put in these videos is stellar friend
Yep we all love the flat fender!!! More, more please…
Fun stuff Fred.
I hope I don’t come across as a flat fender snob, but here goes. The bolts holding the air cleaner on should actually be thumb screws and where you put the tape, there should be another short rubber hose. Having said that, your solutions, in both cases, are period correct ,”bubba fixes” and will only be ticketed by the most anal retentive Jeep police.
A great feature if the oil bath filter is, as you bounce along the trail of the oil splashes up on the steel wool and washes the captured dirt into the bottom of the oil cup. When you go to change the oil in your air filter, most of the dirt will be in the bottom of the oil cup.
Fred! I had this type of filter in my old Jeepster Commando with the “Dauntless” V6 engine, when I was 17. It was cool and gathered a lot of attention.
I ended up reinstalling an old Bendix HydroVac back on my MD since the first owner installed it. Not factory correct but it's period and looks cool. I'm slowly getting closer to trying to start it up. Just converted it to 12v. Will need to mount the battery and wire it still.
Did Fred just use a (bong) reference for the air filter canister? Lol 😆
“Pulled air backwards thru water, or smoke maybe? "
Fred you wouldnt happen to be one of them older kids , huh?
😆🤣
Fred & Dave always seemed to be pretty happy while filming DED 😂
@@TheTulerie
So it wasnt just me that thought that 🤔 😁
Hahahaha he just can't say it can he!!! He wanted to really bad. Fred is so funny when he is awkward. Just say it B0Ng!!! Lol
by far my favorite series! I have a few old cars with those filters but they are sitting on top of the carb, and I always get nervous that they are going to spill into the carb with some spirited driving. You're setup seems better thought out.
Woo hoo 🎉 bedtime in 16:27. 🙌🏻
Love the flat fender. Have you talked about the oil filter yet?
Good class room, thank you.
My 1971 Volkswagen Karman Ghia had an oil bath air filter. Worked great and maintenance was minimal.
Make sure to keep a fire extinguisher handy. 🤘
Love the flat fender series!
What do you think about replacing that tape around the intake elbow with a piece of bicycle tire inner tube? Might last longer?
that would work too. ill do that when my bike gets a flat
Dude that’s so cool
Woooooo flat fender! That is all
OK... I had to think about that sucking air backwards description for a while then it hit me. "Oh... I get it!". I didn't use water... I used wine... and my "wine bath air cleaner" was built from bits I stole from my high school physics lab.
wine?! you must have grown up in napa valley or france
Im one of the older kids that pulled smoke through the water to make bubbles!
hmmm... no bong example to describe how the oil cleaner works?
its in there, you just need to find it
@@4xFredWilliams keep doing your thing Fred. good content.
7:32….
Is it better to use mobile one or Castrol Syntech in this air cleaner? Is there another full synthetic that you recommend?
Use the cheapest oil you can find, usually 30 wt
@@Beat98TJ the manual states to use the same oil you use in the engine.
Back in the day you would use the same oil you used in the engine, which would typically be a single weight oil. Thinner in the winter and thicker in the summer. Multi weight oils didn't come along till a little while later. New synthetic oils would probably be too thin a viscosity in cold weather (Maybe?) and slosh up into the mesh too much...
No. That's serious level overthinking. Any oil will work, even vegetable oil. All it's doing is trapping dirt particles. It's not rocket surgery.
30 weight
I wonder if you found the right size/shape KnN filter, could you just shove that in the canister housing?
Yes, but I wouldn't use a garbage K&N for this application. If you google around, you can find the procedure for modding this and the other common oil bath filter assembly to take dry element filters.
@ 7:20 ....hmm, what type of contraption would be used for said game?
Why would You Suck Smoke through Water back in the Day FRED....lol 😂
This is Selene from Suparee team. I really like your content, can I collaborate with you?😊😊
just realizing that like every tractor from up until the 70's had a "bubbler" pipe... explains a lot really
Don't recommend scavenging oil from an oil bath air cleaner though... that oil is slam full of all sorts of whatever you wanted to keep OUT of your engine... granted a lot of it will settle into the bowl by design... but still a bad idear I guess the engine oil filter would probably catch most of the goo... but it would have to be eatin by the oil pump first so?
My M38 has a little bit different filter inside.
If I can polish the one on the shelf.. It might move after 40 years,,,,
Don’t do it it took 5mph out of my m38a1
they quit using that type because of engine fires in accidents
