cliff Posted July 13, 2013 Share Posted July 13, 2013 Need some help as I got new rebuilt compressor from Fleet Pride several months ago but getting sludge oil in tank. I routinely drain tank after coming back from a show/gathering. It is a 1964 B 61. The engine its self uses very little oil, if any on a run. But I always was told engine oil use does not effect oil collected in the air tanks, only this is caused by bad rings in the compressor. I have drained off the tank enough to clean out older residue from replaced compressor. Any suggestions will be helpful. If it looks like I have a bad new/rebuilt compressor then I will deal with that with Fleet Pride. Thanks.

blackdog2 Posted July 13, 2013 Share Posted July 13, 2013 Does it have a independent supply or does it get it from the in take on the diesel motor if that the case the air filter needs to be cleaned.

220cummins Posted July 13, 2013 Share Posted July 13, 2013 If you just replaced a bad compressor that was pushing a lot of oil chances are it will take sometime for the oil to make it's way out of the entire air system.

Freightrain Posted July 16, 2013 Share Posted July 16, 2013 If it was as sludged up as mine, it took near a summer to get everything cleaned out. I used to get a milkshake out of the tank each trip out. It should have made some kind of noticable difference, but like said it mine have alot of oil in the lines yet.There again, you might have a warranty claim on that rebuild pump too.

cliff Posted July 19, 2013 Author Share Posted July 19, 2013 Thanks again for all replies as I'm checking out each at this time. It does have independent oil supply.

2stacksuperdog Posted July 19, 2013 Share Posted July 19, 2013 I think hes talking about air supply. Quote Matt Link to comment https://www.bigmacktrucks.com/topic/31912-still-getting-oil-in-air-tank/#findComment-194823 Share on other sites More sharing options...
Brocky Posted July 19, 2013 Share Posted July 19, 2013 Check the air supply filter. If it is plugged up, it will create a vacuum in the compressor which would draw oil up around the rings.

Freightrain Posted July 19, 2013 Share Posted July 19, 2013 Remove the little air filter off the side of the compressor and make sure it's not clogged up too bad. It's only a piece of screen if I recall. Quote Larry 1959 B61 Liv'n Large......................

theakerstwo Posted July 20, 2013 Share Posted July 20, 2013 As done been stated it takes a long time to get the oil out of the system.It will drain out of all of the lines and valves in the truck and down to the air tanks when not being used.
