laynrubber Posted June 19, 2014 Report Share Posted June 19, 2014 (edited) Here is a little write up on my mod for an oil bath air cleaner, going to a paper filter element. While the oil bath system I assume works, I thought it would be better for a paper element. Said and done.....the oil bath system is cheaper to operate as the paper filter was $22 Drill out the spot welds in the lid and pry off the metal filter piece. I used aircraft rivets to fill the spot weld holes. You could weld the holes up and grind smooth or use screws but I would recommend locking nuts. The element seal surface will ride on these rivets but they are bucked heavy (flat) so if using screws use the smallest you can find. The elements have a rubber or plastic seal that will conform when the lid is installed. The filter I have currently installed is NAPA #2444 as you can see by the photos I think it should be a little taller. The 2444 is 3" high. I would next try a NAPA# 9227 with dimensions of 6.6" od, 5.1" id and about 3.4" tall. Or a NAPA# 6070, dimensions of 7" od, 4.2" id about 3.5" high. Or NAPA# 2221, dimensions of 6.0" od, 4.5" id and I think 3.6" tall The diameter fits nice on the edge of the oil lip. These filters all have a rubber or plastic edge to seal upper and lower. http://i8.photobucket.com/albums/a14/laynrubber/imagejpg1_zpse3dd29dd.jpg http://i8.photobucket.com/albums/a14/laynrubber/imagejpg2_zps6e003168.jpg http://i8.photobucket.com/albums/a14/laynrubber/imagejpg3_zps3e0fc495.jpg I don't like the lid sitting like this but until I try a taller element....... http://i8.photobucket.com/albums/a14/laynrubber/imagejpg4_zps7bbf3849.jpg I am not sure this puts the lid high enough to feed the 100 horsepower torque monster, I would try another 1/2" taller element next.

RodFru2u Posted June 19, 2014 Report Share Posted June 19, 2014 Great modification, Thanks for the NAPA air cleaner element numbers. I am converting mine and those #'s will come in handy. Quote Link to comment Share on other sites More sharing options...
kented Posted June 20, 2014 Report Share Posted June 20, 2014 Looks like a decent upgrade. If you use the IMG link and not the Direct link on your photobucket you can post pictures right to your thread! Quote Link to comment Share on other sites More sharing options...
laynrubber Posted June 20, 2014 Author Report Share Posted June 20, 2014 Note those NAPA numbers are Canadian NAPA, if it makes a difference. Quote Link to comment Share on other sites More sharing options...
jgreg53 Posted September 10, 2021 Report Share Posted September 10, 2021 Does the motor run any better with the paper element? I haven't seen on here if it does. Quote Link to comment Share on other sites More sharing options...

laynrubber Posted September 17, 2021 Author Report Share Posted September 17, 2021 I do not think it runs any better with a paper element, and really an oil bath one is still functional. I do have a spare original oil bath style but still have this paper set up. No issues. Quote Link to comment Share on other sites More sharing options...
DonaldSmith Posted September 17, 2021 Report Share Posted September 17, 2021 They say air bath is better, and I believe it, as long as it doesn't leak or have other problems. Mine leaked, so paper filter seemed the way to go. Quote Link to comment Share on other sites More sharing options...
jgreg53 Posted September 26, 2021 Report Share Posted September 26, 2021 I tried it. I tore the original apart so I had the top and the bucket. Oreiliys had a WIX filter that fits perfectly. I think the car actually runs better. Quote Link to comment Share on other sites More sharing options...
