No on prefill,  What would be the need?  What good would it do?  None to both questions.

Oil filtering is by-pass filtering.  Only a small amount of oil is filtered at one time.  Most of the oil goes from pump straight to the parts.  If all of the oil from pump went thru the filter, many parts of the engine would be straved for oil and would be damaged.  If the filter is blocked, the engine would lock up from lack of oiling.  The oil must be pumped thru the oil filter, until the oil pump picks up the oil in the pan, no oil moves any where in the engine.

That is the very old filtering system. The current ones including our coaches is full flow filtering. There is a relief valve that opens incase the filter completely blocks the flow.

Old Guy,what kind of prelube system do you have?


It is one I made. I bought a pump (which one day I will upgrade) and a check valve a some fittings.
To operate I use a spring loaded[1] switch and I hold it until I have oil pressure and a bit more and
then I start the engine.

All you need is an accumulator with a diaphragm and a solenoid to build one. Open the solenoid before starting and close after engine is running. The same oil galley port will fill and charge the system. Somewhat similar to the old air starters.

So, now, reading all this and some other reserch on the internet; if I am replacing oil at 50-60% life (and oil looks dirty) why change the oil filter, just change oil now and change oil and oil filter next year. My oil change intervals will be based on time for this truck not so much milage, it will be less than 12K miles for the next year or so. I know ... filter is cheap and just twist it off and put new one on and sleep easy :-)

The LF3000 or LF9009 are both full flow and by bass built into one filter. I just learned something
new as I thought the were just full flow as most filters are. I run my prelube through the filter as
I want all the oil filtered. The reason for the prelube is that engine gets the most wear during startup.

Peter those are obsolete filters for the ISM. Cummins recommends FLEETGUARD LF14001NN. There is another filter that has a lower service life so I just went with the better one of the two. Take your serial number and go to the cummins web sight to verify. There is a service bulletin that covers and Im pretty sure we talked about this before. The reasoning for the post shutdown lubrication was to lube and cool the turbocharger. FOA sells an oil accumulator with a solenoid. But I think it has to be charged after use causing lower oil pressure during that moment of charging.

Oil filter
Link is no longer working to filter

So i contacted Cummins and this is the information they sent me for me 2001 ISM450
Scott,

Thank you for contacting Cummins.  The resolution to your inquiry, ISM oil filter, is as follows: You can use the LF14000NN or the LF14001NN which is the upgrade.


LF14001NN vs LF14000NN

what's the difference between the LF14001NN and the LF14000NN?

Both filters are 2 stage filters using Stratapore media for stage 1 and Nano Net Media for stage 2. Both have equivalent micron ratings. The LF14001NN is just the extended service option of the LF14000NN, simply put, theoretically speaking you are going to get a little more life out of the LF14001NN depending on the quality of the oil used. If you are like a lot of owners you may be well under Cummins recommended service interval. In that case you can't go wrong with either of these filters. If you need to get a little more life out of your filter and make ever mile count. then the LF14001NN may be your best bet.

I doubt it will burst into flames. Chuck had found a link and currently they are  $75 each

Have rebuilt hundreds of industrial engine turbos and 99% of them failed due to oil starvation,the oil passages coked up with
overheated oil,most large industrial engines have a post lube just for the turbo.
 Propman,where are you getting the 50-60% from?

Engine computer indicates 58% oil life, so oil change is not due for sometime. However oil maybe a year old. I usually change oil every 12-15 months, do it before if we drove and put miles.

John he is asking about a 2018 Dodge Cummins ISB. The computer generates reccomended oil change interval.  Non dinosaur.

I was getting my oil filters from NAPA until they got so high priced. They told me I could
get a better price by getting 6 filters. I said no. I went done to my local farm implement dealer
and they stock the Fleet Guard filters. There were  almost half the price from NAPA store.
