When's the last time you drained your air tanks?

 

How old is your compressor?

 

Drain ya air tanks, replace air drier cartridge, the compressors on the sdp cats are bad for putting oil in the air system when they get a few miles on them. I think i saw a service letter on them a while back.

 

Ok just the reason I asked was because mine when I got it was filling the air tanks with oil. Cat put a new reman Bendix compressor on and for now all seems to be well. I also remember hearing that the compressors on these engines only last a year or two and aren't made very well at all. I was lucky, however, and that the oil didn't go through my entire air system. Only had to replace rear end leveling device. You could have an output test done on it to check. And I agree with changing your air dryer cartridge yearly, I do mine about now just before the brutal cold of winter arrives.

 

With a properly maintained and functioning air dryer your tanks should always be dry.

 

correct.


to Billerd:
If you are draining your airtanks daily something is seriously wrong.
You should have replaced that compressor a long time ago.
And by waiting to replace it,you will wreck all your airvalves which will cost much more then the compressor.
That's my opinion.
