d427 Posted November 2, 2012 Share Posted November 2, 2012 Hello everyone. I was trying to figure my oil bath air cleaner out and was wondering if you guys could tell from the pics if I am missing anything. There are two holes in the firewall and I was wondering what the lower hole is for also. The top one obviously goes to the intake. I would rather go with a dry filter setup but they are a little pricey so I figure if I can service this one why not. Thanks for your help this is my first Mack.

Superdog Posted November 2, 2012 Share Posted November 2, 2012 the bottom hole is so the aircleaner can draw air from under the hood in bad weather.There is a little lever that closes the outside draw on the front side of your air cleaner.I had one B-61 that had a dash mounted cable control to open and shut the vent.

d427 Posted November 3, 2012 Author Share Posted November 3, 2012 Thanks for your help. I still cant figure out the top of it though. It just seems to let water in through the hole in the top. Quote Link to comment Share on other sites More sharing options...
Maddog13407 Posted November 3, 2012 Share Posted November 3, 2012 the later models 64-66 had the cable in the dash that crudely went thru a unused bolt hole in the air cleaner mounting to the winter/summer switch. the top of the air cleaner usually had a plug in it and some even had a little flip top screwed in where you squirted the old girl with ether in bad weather. you could do this or just spray it in the screen on the bottom. i dont really get what you mean by the hole in the top that lets water in? the oil bath will work fine for most applications, sometimes when you upgrade to a 237 or bigger engine the engine will actually suck the oil right out of the pan on an oil bath air cleaner thats why a lot of guys upgrade to the dry type. the dry type Watts sells is a Donaldson to along with the original oil bath Mack used. the dry type is available direct thru Donaldson also as it was used on various applications, i have even seen them on log skidders.

ajt3138 Posted November 3, 2012 Share Posted November 3, 2012 but what is that thingamabob extending up out of the top. mine is a plug looking deal. aj Quote Link to comment Share on other sites More sharing options...
Maddog13407 Posted November 3, 2012 Share Posted November 3, 2012 dunno. seen the dry type have the little taddle tale (change filter. rest ) thing screwed in there. id just take it out and put a plug in it and should be fine. only problem with those air cleaners is if they are left outside forever, they tend to rot around the top ring(where the water rests) and eventually leaks inside and rots the screen and fills the oil bown full of water.

d427 Posted November 3, 2012 Author Share Posted November 3, 2012 Thanks everyone! I will clean everything out good and plug the top. Any chance those removeable filters in the bottom are still available? Quote Link to comment Share on other sites More sharing options...
