Bypass Filtration

No, the oil under pressure spins the centrifuge, the air line operates a control valve at the bottom.

Air Supply Air for the control mechanism can be taken from any convenient place on the vehicle air system where there is a constant supply of air, preferably from the dry tank. 1 ⁄ 8 -in. nylon tubing is sufficient or #4 hose can be used if preferred. Air pressure can vary from 35 to 125 psig. No regulators, valves or control devices are required. The Spinner II control automatically shuts off the air supply when the engine stops. 0.02 SCFM air consumption is almost too small to measure. Note: The control mechanism can be operated on bleed air taken from the turbocharger manifold if compressed air is not available. The standard air valve must be replaced by Part #72137 low-pressure air valve cartridge which includes a pre-filter Part #71246. Request Bulletin 86.020 for details.

 

Note to DD 13/15/16 users:
Par 6.2 of the Filtration Manual says; "The use of supplemental by-pass oil filtration devices are not allowed on DD13, DD15, and DD16 engines."

I have a 2011 DD15 in a Coronado (love it by the way) and found this little tidbit in the filtration manual (I was going to put in my prior used FS2500).

 

Are you referring to a Detroit Diesel manual? If so, I think that phrase is standard in every manufacturers literature. IIRC, NONE of them condone or support extended service intervals beyond what is in their manuals.

 

I have a Spinner and have had it for about 2 years now I have replaced the cartrige twice (The one I have has a cartrige that you replace when it gets to a certain weight) I increased my oil change interval for the first couple of oil changes but have since decided that I don't want to run the oil for that many miles...I send a sample out at every oil change and they have been quite a bit cleaner since I installed the spinner.

The air doesn't spin it....Oil pressure does.

I have mine mounted just ahead of the right spring shackle on my W9 and the lines are very short.

 

Navistar, with the Maxxforce engine using so-called "advanced EGR" is still recommending lower oil change intervals of around 25,000 compared to Detroit's. But, Navistar is now factory installing Spinner II's as an option and upping the recommended oil change interval to 40,000 miles.

Guess they are siding with the Spinner brand.

 

40,000 miles? No thanks!

 

This is the first time I have heard of any OEM engine manufacturer stating not to use a bypass or something similar. They have allways recommended not using oil additives or supplements, but usually don't say anything about oil bypass systems.

True, they all do not support extended service intervals, but they do put in the fine print that any extension must be supported by proper oil sampling. The manufacturers CANNOT deny warranty because of any add on device, unless it can be shown that the device in fact caused the damage. Same for brands of oil, whether synthetic or not, etc. The Magnesson-Moss Warranty Act, lays this all out. Manufacturers have been trying to scare everyone for years. The ONLY way they can deny a claim based on extending oil service intervals, is to show that the oil condition was at fault and caused the damage. Proper oil sampling is all the proof you need to satisfy the provisions of the Magnesson-Moss Warranty Act. Say you blew cam bearings. They may say that it was your extended services that did it, when it was the fault of the bearing quality. Oil sampling will justify the oil condition, and holds up in court. But, I have seen engine manufacturers deny claims even though the oil change intervals were followed. They will use stupid arguments regarding brand of oil, type of filter, etc. Sorry, but won't hold up unless it can be proved it was these items fault. And it is the manufacturers responsibility to prove in a court of law that what they claim was at fault, actually was. It is NOT your responsibility to prove that what you did was the cause of the failure. The Warranty Act lays this all out. You can find it easily online.

Just take in your oil sample records and say "read it and weep". This is just another case for doing regular oil sampling, especially with a reputable oil analysis lab. Cheap and easy insurance.

 

I'll tell ya, I would be hesitant about going that long with one of those engines. But, if the oil sampling showed it was ok, then I might consider it. If I had one of those engines, I would start lower and work my way up each oil change and see what the oil samples looked like. Then I would decide if they are full of it or not. The carrier I am leased to has a few of the new DD15's and are taking them out to that long oil change interval recommended by Detroit. So far, the samples show that it is ok. Would make me feel a little uneasy if it was my money on the line.

 

Wonder how they knew they had to change there oil if it was not being tested???

To the ones who think a GCF is messy to change either aint doing it right OR dont own one in the first place.
