I have an M38. The manual calls for a vent from the gas tank to the air cleaner. Does this one have a vent port on it?

Willys Jeep Parts Tech:
No, these do not have a vent port.

Want to install oem type air cleaner on 1963-64 CJ-5 with Fhead 134 would this be an oil bath type?

Willys Jeep Parts Tech:
Yes that would be an oil bath. But this is only for the 134 L engine. You can only find the one for the F head through a salvage yard.

Could this air cleaner assembly be used on a 1960 CJ 5?

Willys Jeep Parts Tech:
Yes, just make brackets to mount to firewall.

What is the dimensions/diameter of the outlet to the carburettor

Willys Jeep Parts Tech:
Approx 2" like original.

Hello I have a 1947 willy's jeep that has the oil bath air cleaner - can this be removed and a modern cone filter (K&N type) be installed? Thanks

Willys Jeep Parts Tech:
647789 is a good option

I have a 1952 M38 which has a 1953 F head and I need an air cleaner which could sit under the hood? Any ideas

Willys Jeep Parts Tech:
If someone put an unoriginal motor in your M38 this 645368K-BRK should still work for you on the passenger side firewall.

Hi, do you have the air filter assembly for a 1954 CJ-3B? I haven't been able to find it on the website

Willys Jeep Parts Tech:
No one makes the assembly for the 4-cylidner overhead valve motor. Give me a call toll free and we can go over the options for you. 888.648.4923. Thanks

what is the diference respect the reference 645368K ?

Willys Tech:
One has the brackets to attach to the firewall.

I have a 1959 CJ3B. Will this oil bath air cleaner assembly fit my vehicle?

Willys Tech:
Im sure it would with some modification.

WOW really feel ignorant here. Looking for an air cleaner for 53 M38A1 and just found about 1/4 of oil in the bottom of the air cleaner of the 53 I just purchased. Feeling stupid, I write this question. Is it supposed to be there? The carburetor has been replaced and the air intake system sits idle. carburetor just has a small 3-4 cleaner screwed on. Eventually I want to return that to original.

Willys Tech:
Yes it is a oil bath air cleaner. There should be a stamping on it for the proper fill level. That is the air cleaner.

Do you have a graphic showing how the firewall brackets are mounted?

Willys Jeep Parts Tech:
I can email you some images of my CJ-2A. Please email mike@kaiserwillys.com and we can help.

Trying to clean the gunk out of my 1950 6-73 Willys jeepster. Does this canister come out or what? If not how do I get the dirt out of it.

Willys Jeep Parts Tech:
The wire mesh wont come out. You would need to soak it in degreaser and hose it out really good then let dry.

Hello, I had to remove the gasket that seals the bottom oil bath pan to the Oil Bath Air Cleaner housing so that it could be powder coated. It fits in the groove between the two half's. Is there a gasket available to replace the one I had to remove? Thanks

Willys Jeep Parts Tech:
That lower gasket you have to make.

can you modify for a 60 CJ-5 since you have the horn and tubes to connect?

Willys Jeep Parts Tech:
Im sure it possible. You really just need it to mount the the firewall.

Does this kit come with the filter element?

Willys Jeep Parts Tech:
Yes, this is a complete unit. Thanks

looking for the same unit to fit 1960 cj5 with 134 hurricane

Willys Jeep Parts Tech:
That is available good used only. Call us toll free and we can try to help out.

My oil bath air cleaner has another opening at the top that has a pre filter mushroom cap on it, this is also where the fording air intake would attach if hooked up, correct? Do you sell these type of cleaners? I can't find the exact one in the catalog or on the web site. Also is there an inner element that needs serviced or do you just replace the whole system? Thanks for your time!

Willys Jeep Parts Tech:
That style for the military is only available used. Please call us toll free and we can forward you to some salvage yards.

https://www.kaiserwillys.com/diagram/cj-2a-diagrams/fuel-exhaust-diagrams-willys-cj-2a/air-cleaner-view-2-46-49-cj-2a/air-cleaner-view-2 This link is a diagram to show you how it went.

I have a early 46 Cj2a. An earlier question from someone about mounting was answered that this unit mounts directly to the firewall. I also find that brackets # 640948 driver side and #640947 passenger side are required to mount to the firewall.according to your listings. will this unit mount directly to the firewall or are the other 2 brackets also required?

Willys Tech:
This kit above comes with the brackets. So it will mount to the firewall.

What hoses, brackets, etc do I need for the entire oil bath assembly?

Willys Tech:
This is a completet kit for the oil bath canister itself. You can also get part numbers: 648024,648024-CLAMP, A17317, A17318, A17318-CLAMP & 641918.

will tis work on a fc 150

Willys Tech:
Im sure it would with some modification...it would be tight....

how does the air cleaner mount to the body

Willys Tech:
This comes with the left and right mounting brackets to the firewall. It mounts up just like original.
