Robo987 Posted April 15, 2022 Share Posted April 15, 2022 Has anyone modified the oil bath air cleaner? I like the look and don't want to get rid of that setup but would like to add an actual filter. Just wondering if anyone had some ideas. Quote Link to comment https://www.bigmacktrucks.com/topic/69538-oil-bath-air-cleaner-modification/ Share on other sites More sharing options...
Brian L Blaylock Posted April 15, 2022 Share Posted April 15, 2022 My B-615 had this done by a previous owner by removing the internal parts moving the breather connection and mounting upside down Quote Link to comment https://www.bigmacktrucks.com/topic/69538-oil-bath-air-cleaner-modification/#findComment-495387 Share on other sites More sharing options...

mowerman Posted April 15, 2022 Share Posted April 15, 2022 But if I were you I would check wrecking yard get a later one and see if you could weld your stack onto the newer unit Yes most of us like the tall stack on those ….

Freightrain Posted April 15, 2022 Share Posted April 15, 2022 Been contemplating this change on my truck for years. Haven't wanted to cut the original yet, been hoping to find a used SS model that might fit well. I know Watts used to offer a dry filter set up but is a bit pricey these days. I know oil bath is supposed to be better but I know my 237 sure does pull a lot of oil through the intake pipe. 1 Quote Larry 1959 B61 Liv'n Large......................

mattb73lt Posted April 16, 2022 Share Posted April 16, 2022 I’m running gear oil in my oil bath filtered 237. That’s what was recommended when I swapped in the 237. Haven’t had any issues with it sucking oil with the heavier weight oil. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/69538-oil-bath-air-cleaner-modification/#findComment-495438 Share on other sites More sharing options...
mowerman Posted April 16, 2022 Share Posted April 16, 2022 That’s ingenious I wouldn’t have thought of that Quote Link to comment https://www.bigmacktrucks.com/topic/69538-oil-bath-air-cleaner-modification/#findComment-495466 Share on other sites More sharing options...

Keeps with the authenticity. Quote Link to comment https://www.bigmacktrucks.com/topic/69538-oil-bath-air-cleaner-modification/#findComment-495544 Share on other sites More sharing options...
doubleclutchinweasel Posted April 18, 2022 Share Posted April 18, 2022 The R611 I drove when I was a young-un had the oil bath air cleaner converted to a dry filter element with a kit that was supposedly available from Mack. I tried to find a kit to do that to the one I had later, but it was apparently no longer available. Considered getting a Donaldson aftermarket body to put on it. Never thought about the gear oil thing. Sounds promising, though. 1 Quote "Eagles may soar, but weasels don't get sucked into jet engines."

Popular Post davehummell Posted April 18, 2022 Popular Post Share Posted April 18, 2022 I looked around and ended up buying that dry type of air cleaner from Watts. It fits the truck and looks like it belongs on my mack. 2 1 Quote Link to comment https://www.bigmacktrucks.com/topic/69538-oil-bath-air-cleaner-modification/#findComment-495570 Share on other sites More sharing options...
Robo987 Posted April 20, 2022 Author Share Posted April 20, 2022 I looked around and I could replace the air cleaner but I think I’m just going to keep the setup I have. I want it to look as original as possible so I think I’m just gonna keep it. I was hoping for a trick to modify the current housing but I don’t want to alter anything to much.
