Questions: Do you know if this fits a 1961 DJ3A?
Question By: Sami on Dec 9 2020 1:51 AM
Yes, this should as long as you have an original filter.

Questions: Hi, I inherited a 1946 CJ2A from my father in-law. I am not a car person, but am teaching myself the ropes by YouTube and online forums. My question is this Jeep has the oil filter removed, I have read that some think this was due to oil starvation which I don’t really understand but I am thinking that it would be best to reinstall a filter. Is this a good idea? Where do the oil lines for the inlet and outlets get connected on the engine? The wiring is a mess too, eventually I will have to re-wire. Also, the oil bath air cleaner looks to be the incorrect one according to all the info I have found. This Jeep has sat undriven for almost 12 years, before my father in law got sick, he was using it around the house for was runny my. 8 would eventually like it to be road ready, not just for trails...lots to learn!

I personally always run an oil filter and have not ever had any oil issues. If you dont run a filter just make sure you change your oil regularly before the 3000 miles change.

Questions: Mike, I am changing the oil in my 1956 cj5 and I noticed the Fram Oil Filter canister did not drain when I pulled the oil pan drain plug. Is that normal? And short of removing the outlet hose from the filter canister, is there a way to drain this? Thanks Kevin
Question By: kevin mathison on May 28 2018 1:32 PM
You have to manually drain the filter. I would complete remove it and clean it out if you can too.

Questions: I ordered this oil filter for our 49 CJ2A. The included gaskets are too small for the lid. I need a gasket approximately 4-5/8" OD and 4-1/4"ID. What do you have ?
Question By: Skip on May 1 2018 7:59 PM
The gaskets are correct for the original fram canister. If you can call me toll free. Ask for Mike M. we are happy to help out.

Questions: I've just installed this filter on my rebuilt 48 CJ2A for the first time. Prior to doing so, I noticed a disc and spring in the bottom of the empty Fram canister. I assumed that should stay put, and I simply inserted the filter into the canister, on top of the disc and spring, and bolted the top back on. Is that correct?
Question By: Matt Mayer on Nov 10 2016 3:00 PM
Depending on which canister style you have I would leave what you had in there and simply install filter. If you like email and I can look for you too.

Questions: I have a 48 cj2a and bought this filter for it and can not get the cover back on with the rubber gasket on top of the filter. The old filter I took out was a little different on top. Any thoughts? Thanks.
Question By: McComas on Aug 10 2016 5:09 PM
Please send us a photo of your canister and we can try to help out. Thanks!

Questions: What is the filter life before changing? Can a person get a different brand of filter that works just as good? Thanks
Question By: Dave on Mar 14 2014 12:00 AM
I doubt you would be able to find the right one locally. We usually shoot to change the filter every 3000 miles or less due to the nature and age of the Willys engines.
Answer By: Willys Tech on Mar 14 2014 12:00 AM
Questions: What is the diameter of this filter? I just picked up a '43 MB that appears to be original, but apparently doesn't have the correct engine in it. The filter on my engine is 4.25 tall and 3.75 diameter and fits in a 4 diameter canister.
Question By: Geoff on Oct 28 2012 12:00 AM
3-3/4 just like original for civilian canisters.

Questions: I have a 44 Willys CJ-2A with an F-Head 134. I got a filter on line and it was too big for the canister. I found this was for an L-Head 134 or Flat head. Do you folks have the other one? Thank you
Question By: Dann on Aug 18 2012 12:00 AM
The 4-134 L & F heads used the same filter. There are military and civilian canisters. Your CJ would use this one. You may have an unoriginal canister since you have an unoriginal engine in there.

Questions: What kind and weight of oil do I use in my 1948 Willys CJ2A with the 4-134 motor? How many quarts with the filter? Thanks, Harry
Question By: Harry on May 2 2012 12:00 AM
We typically tell people 30 or 40 weight non-detergent depending on their preferance.
Answer By: Willys Tech on May 3 2012 12:00 AM
Questions: I have a 1961 CJ-3B. Do you recommend detergent or non-detergent oil.
Question By: Larry on Feb 1 2012 12:00 AM
Non-detergent if you have not rebuilt the motor recently. That way any sluge on the bottom of the oil pan doesnt get stirred up.
Answer By: Willys Tech on Feb 1 2012 12:00 AM
Questions: Two rubber gaskets. Which goes where? I have oil running out between the canister and cover and have tried each of the gaskets on the top. Does one go inside the canister on the bottom?
Question By: Gerry on Sep 21 2011 12:00 AM
Just use the one that fits on the top of your canster is all you need.
