Deleted EGR, can I run regular Diesel oil now and not LE oil????

Hello, First post here... I own a 2007. 5 Ram with the 6. 7 Cummins, I'm interested in trying to keep the engine oil as clean as possible and I am looking for information or opinions on installing a Fleetguard Centrifugal Separator. I don't have an air pump installed so I was looking at the gravity model CH41102. Does anyone have one of these installed? I am considering this instead of a oil bypass filter system, and have looked at other Centrifugal systems as well but am leaning toward the CumminsFiltration system only because they make the engine, they probably know what they are talking about (less smoke - no mirrors!).



If anyone has something to add, I'd appreciate the input.



Thanks for reading,

Glenn
 
ken we have two centrifuge filters on some of our big engines. they are the best filter available you really have to watch the oil flow if you try to use one on a 5. 9 cummins recomends limiting the oil flow to what can go through a 0. 032 inch hole and this is not enough to spin ours. check with cummins first. we looked at one that will work on the 5. 9 and had a small pump for the return eleminating the gravity problem it may take me a while to dig up the literature but if you want i will get it.
 
I have that unit myself, but have yet to install due to the combination of fleetguard's plumbing directions and being unsure of a proper mounting location on our trucks. Since the unit is gravity fed fleetguard recommends a very large return line in the install literature. If you have ever seen the factory centrifuges on a Mack engine it is almost identical with the exception of using oil pressure instead of air to spin the centrifuge.
 
I forgot to add that if one could ever work out the mounting logistics you could not have a more service friendly bypass filter. One bolt and o-ring replacement and you would be done. Plus, the price was pretty economical if you could get a good deal on the lines and fittings. They do not have a install kit-only directions for hose and fitting sizes.
 
most of my trucks have headache racks on them, i mount a lot of my lf777 bypass filters on them. i was thinking if i tried one i would mount it here and run the return line to the extra turbo drain hole on the block

That is a good idea. I am just wondering if you need to compensate with a greater quantity of oil to overcome the quantity lost in the lines draining back from the bypass filter base. Might be a non-issue. The installation literature says to have 1 foot of drop per 3 feet of hose with unit at least 1 foot above drain return line, and the hose should be a minimum of 3/4 inch minimum interior diameter.
 
I was reading about those a while ago, it seems they want 60 psi to function properly. I am rarely at 60 psi, so I don't think you would get much out of them on a ISB.
 
I'm not up to speed on what the oil pressures are on the 6. 7, Cummins also makes a CH41101 that requires an air source, maybe that would solve the oil pressure concern (if I understand it correctly, it would use the air pressure instead of oil pressure to "spin"). Also that may relieve the gravity drain concern as well. I haven't bought anything yet, I was hoping someone already installed one and could share their opinion on whether or not this filter is worth the effort, especially as it doesn't appear to come as a kit with lines, fittings, instructions, bracket, etc.



If anyone else can add more, I welcome the input.



Thanks,

Glenn
 
I beleive oil pressures are about the same from the 5. 9 to the 6. 7. The way I understood the one that uses air is that air is for oil evac, and it still uses oil to spin. Besides, where are you going to get a constant 30 psi of air on these trucks? Thats either a large electric comp, or a $$ engine driven one.

Hopefully someone has done some more research.

I feel like you are right with the desired oil pressure to run this unit on the 5. 9

This might work with a marine unit or generator where you are at higher rated usage constantly where your oil pressure would be higher?
 
Glenn,



I recently ordered and received one of these Fleetguard gravity model CH41102 kits from a friend who is the parts service manager at Hutson Ag John Deere dealer. He spoke with a Fleetguard/Cummins rep. who worked out the details of how to order the kit (which costs about $275 if my memory is correct by the way).



I can say that the first logistical challenge with be finding the space and location to mount this bypass filter. (it is a MONSTER compared to the Spinner II)



The Fleetguard/Cummins rep. says this unit will work on a 5. 9 liter engine, as does the documentation.

Recommended oil pressure for this unit is 44 - 87 psi. I think our engines will make the minimum oil pressure for the large percentage of the time of use and be adequate to operate the centerfuge cone stack filter.



The only centrifugal bypass oil filter on the market that I am aware of that has been specifically designed to work in our trucks is the Spinner II. It is not near as good a filter as the Fleetguard but will at least fit under the hood on the battery hold down long bolt.

You can download the installation manual which also lists the parts for the drain and fittings for the engine block drain into the oil pan as well as other specially designed hardware.

Very pricey for what you get but it is an option. The hardware kit may be what we need to mount the Fleetguard unit but the battery hold down bolt is NOT a mounting option. The mount bracket and filter weigh around 10 lbs. more or less.



I am gonna send this kit to a friend who has MUCH more experience in this area than I do and let him have a look at it. Perhaps he may have a brain storm that I missed. :D



Anyhow, I will definitely be following this thread and will post whatever info. I find out. Hopefully we can figure a way to mount this filter on our trucks after all.

If it turns out we can figure out a way to mount this filter in our trucks, I may be able to work out a group buy on this filter kit from my John Deere dealer parts manager and get it at a discount on the price if there is enough interest in this.
 
I certainly welcome the interest! I did get a positive response from Cummins Filters saying the CH41102 would work with the 6. 7. I would prefer the gravity model to the other one needing an air source, (I don't have an air source on my truck).



I'm interested in both a group buy (if there is enough interest) and learning more on what is needed to make this filter work, (fittings, mounting location, etc. ).



I 'll pass along anything else that shed's some light on this question.



Thanks,

Good to hear. I did some more searching and found that 60psi is the optimal pressure, but they work from 44-87 psi. Cruising at 80 my psi runs from 55-62 depending on load, and engine temp. Normal is about 58. I have only seen my psi drop below 40 while cruising once, I was at 70 and pulling a long hill in OD with 2 trailers and the oil temp was high enough the psi dropped to 38, so I would say that 99% of the time you will be within 44-87 psi while driving.

Hopefully with some outside the box design and thinking, a friend who posts on TDR may be able to work up and fabricate a mount for this bypass filter. I just don't think a battery mount is going to be practical as this filter is a monster in size and weight compared to other bypass filters.



I like the idea of being able to potentially extend my oil change intervals. My biggest problem is soot build up. These filters are supposed to be very good at soot control and removal.
 
After doing some more digging, I'm shying away from this filter as the published oil pressures from the Service Manual indicate the oil pressures to be lower than what makes the filter effective. From the service manual for the 6. 7:



OIL PRESSURE SPECIFICATION

SPECIFICATION



At Idle

69 kPa (10 psi)



@ 2500 rpm

207 kPa (30 psi)



Regulating Valve Opening Pressure

517 kPa (75 psi)



Oil Filter Bypass Pressure Setting

344. 75 kPa (50 psi)



So I'm off trying to decide between the FS-2500 bypass filter set-up or the Dieselcraft OC-25. I still have some work to do... .



Thx for the input,

Glenn
