davehummell Posted January 5, 2020 Share Posted January 5, 2020 After I got done putting the later engine in my b I just test drove it about 5 miles, Friday I got the new air cleaner from watt's and I pulled the old one off the truck and I stuck my hand in the intake tube on the truck and there was oil more than a film so I am figuring that oil bath that was on the truck didn't like breathing through my turbo just something to think about. And no it was not over filled and I serviced it under a thousand miles ago. Wow the 3.90 gears and 260 hp. really makes the old thing pretty jippy! 2 Quote Link to comment https://www.bigmacktrucks.com/topic/60407-air-cleaner/ Share on other sites More sharing options...

Maddog13407 Posted January 11, 2020 Share Posted January 11, 2020 I have often wondered about guys who put a 237 or more in a B and some guys say it will suck the oil out of the oil bath and run on and tell you to change to a dry type.. but then again the early R685's had oil bath air cleaners..... 1 Quote Link to comment https://www.bigmacktrucks.com/topic/60407-air-cleaner/#findComment-440036 Share on other sites More sharing options...
Freightrain Posted January 11, 2020 Share Posted January 11, 2020 (edited) I have three years running an oil bath with my 237. No problems. Has not sucked it dry, though I know it does have some oil film in the pipes. Nothing catastrophic, but I would like to put a dry filter on it someday. Hopefully a stainless model from something newer. I did hot tank the filter years back when I painted it so I know it's clean mesh.

Hobert62 Posted January 11, 2020 Share Posted January 11, 2020 I’m guessing that how turned up it is makes a difference. Quote Link to comment https://www.bigmacktrucks.com/topic/60407-air-cleaner/#findComment-440094 Share on other sites More sharing options...
Rob Posted January 12, 2020 Share Posted January 12, 2020 The R model oil bath air cleaners are constructed differently internally than a B series was. They are larger and the oil level is maintained lower in the sump. They too pull oil at times but the plenum being longer doesn't allow much to be sucked into the piping. That is just what I've noticed from being around and servicing both types in my earlier years. 1 Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

Truck Shop Posted January 12, 2020 Share Posted January 12, 2020 This 11" is not a bad fit, from a Freightliner 90's model FLD. Quote One ping only Link to comment https://www.bigmacktrucks.com/topic/60407-air-cleaner/#findComment-440175 Share on other sites More sharing options...
Hobert62 Posted January 13, 2020 Share Posted January 13, 2020 (edited) That’s what mine is. It’s a Nelson. On mine a buddy shortened it 3” or 4” so it fit right and didn’t go way up the window. I have it as close to the fender as possible about a finger thickness. On the 70 series B’s you have more space to slide it lower. Idk about a b61 on a side note my buddy is a welder/fabricator. He said this was the worst stainless he ever welded and was not at all happy with his welds on it.

I've seen some very poor quality stainless over the last few years...mostly on hardware coming from China.

Rob Posted January 13, 2020 Share Posted January 13, 2020 Most of the 18-8 rated stainless steel will pit and sometimes rust. I ceased ordering from Fastenal because of this and had to find a vendor whom still supplied true "304" stainless. Was really bad on coastal installations.

davehummell Posted January 13, 2020 Author Share Posted January 13, 2020 The anti rust quality's we all like is due to the amount of chromium and some other added materials. For instance 18-8 is the go too for average hardware it is stronger than specialized aluminum but not as strong as hot rolled. 400 stainless is what your average guns are made of lower chromium easier to machine most custom ss rifle barrels fall in that category. 304 some say machines better than 316 they are gummy when you work it. I had some contracts I had to use ss and always a letter of origin to prove what material I provided. 12L is a dream come true for machining but you have to be careful when welding makes great hardware if you don't need ss. You can go nuts trying to keep up with what engineer's request. My cost for a an aluminum 4"x6"x48" for one job cost 1,000.00 thank god I didn't screw up. I had a shaft on my bigger lathe that I had to fix, someone didn't read the blueprints that shaft was 5000.00. If you ever heard of golden technologies lift chairs every one of those chair subframe's went threw my shop for over 15 years.

Rob Posted January 13, 2020 Share Posted January 13, 2020 I actually have heard of that "Golden Technologies", and their chairs. I've worked with many business entities whom work with elderly/handicapped individuals and have seen that name on correspondence several times. Never have seen any of their product however myself. We/I did a lot of accessibility for local school districts and transport in the smaller busses used including floor modifications and installation of specialty mobility options. Still have several chair lifts around the shop which were removed when vehicles were rotated.

B61Hobby Posted July 2, 2020 Share Posted July 2, 2020 I am thinking about switching over to a dry air filter system on my B61. I am still trying to figure out the exact engine specs on it but I know it is the in-line 6 turbo diesel. What do you guys and gals think? Keep the oil bath or convert to dry?

davehummell Posted July 2, 2020 Author Share Posted July 2, 2020 I bought the air cleaner from Berry over at Watt's and it went on with a new manufactured mount looks about the right size not to big. I like it Quote Link to comment https://www.bigmacktrucks.com/topic/60407-air-cleaner/#findComment-454682 Share on other sites More sharing options...
mrsmackpaul Posted July 2, 2020 Share Posted July 2, 2020 Well I guess you need to ask your self why you want to change it Oil bath lasts for ever and work as well if not better than a paper element type Only down side to a oil bath is you can get a bit messy when service time is due Oil bath are cheaper to own and operate and work far better in extreme conditions Dunno if -40 changes the efficiency of them as I have never been anywhere that gets that cold So I would just leave it Paul 1 Quote Link to comment https://www.bigmacktrucks.com/topic/60407-air-cleaner/#findComment-454694 Share on other sites More sharing options...
