2008 Knight oil change

Hi I have a 2008 Monaco knight and want to change my own oil in the engine. Does anyone know what the oil filter P/N is?

Thanks,

It's in, or should be in, your owner's manual. We have the same basic engine and mine uses an LF3000 from Fleetgaurd. Filterbarn.com is where I get mine. I use a large storage container from Wal-mart to catch the old oil.

part numbers

I know the owners manual is long but every time I read mine I learn something new. I actually have it in digital form and can print pages out of it when I want to grease something or buy filters etc.

I have an 08 Endeavor with a 400 ISL which is probably what you have.

Even if you don't have that engine your manual should have a page that looks like the one attached.

A good friend of mine recently retired from the parts counter at Cummins. She would not sell me an oil filter until I brought her the engine serial number. She said Cummins had changed oil filters about that same time because of emissions changes to the engine and she wanted to be certain I had the right filter. My engine uses an LF9548 oil filter. Cummins added a crankcase ventilation (CV) filter in 2007. The filter list in my owners manual looks exactly like the one posted by YC1 and it does not list this new CV filter. I feel that this page in the owner’s manual contains out of date information. Cummins recommends that this filter be replaced every few years, so I feel it should have been listed in the manual. For my engine, the filter is a CV50628. There is a Breather Tube Assembly, 4945226, that should be replaced the same time the filter is replaced. The drain line stops up and the tubing will collapse in the bends. JDT says he uses an LF3000. The LF 3000 was upgraded to an LF9009 quite a few years back. I wonder which filter Cummins says he needs. I can’t blame this out of date information on Monaco. When we get a new diesel generator at work, it isn’t unusual for the manual shipped with the generator to have different filter numbers than what is actually on the unit. I see this with Caterpillar, Onan, and Olympian units. Don’t trust the manual. Get the serial number off the engine; the tag is on top of the engine, turbo charger side. Write down all of the information, take it to Cummins and let them tell you what you need.

That is interesting. I would love to see a picture. I think I remember in my paper Cummins book that we can order a complete build sheet for our engine serial number. I guess I will check that out and order one.

Steve the LF 3000 JDT uses is still a good filter and filter # and the LF 9009 is the newer extended use filter or some time called extended drain filter also the one I use and available at Filter Barn. I agree call Cummins with the engine SN

Steve,

Sorry to say but your friend's information is incorrect. The LF9548 is a smaller version of the LF9009 Venturi Combo lube oil filter. That would be the correct filter for a Case farm tractor with a Cummins engine. It is made for that application as it does not have sufficient clearance for removal in the tractor chassis. The filter you have now has less stacked disk bypass in it than the correct, LF9009. Likely the price is higher too as we do not make a large number of those as compared to a much larger volume of LF9009. Beginning in 2007, ISL starting using the LF9009. Previously, the lube filter was LF3000. The two filters look alike until you look down the threaded portion into center tube. The LF3000 has a small tube in the center with a rubber gasket. This is the bypass section return oil flow into the crankcase. The LF9009 appears to have a black plastic funnel with a small pipe in the center surrounded by three elongated holes in a circle. This is the venturi section. The LF9009 will filter more (approx. 3X) oil in the bypass section than the LF3000 will. The stacked disk bypass filter is the same size but is utilized more in the life of an oil change to remove more of the combustion byproducts than its predecessor LF3000. Any Cummins engine that uses the LF3000 can use the LF9009 or LF9548 if the correct filter is not available. Even if you use the LF9009 all of the time in place of the LF3000 you still avail yourself of a better filtration in that you get the required full flow volume plus a higher volume of bypass filtration while having two gallons per minute draining from the filter head passage that is in place for draining the LF3000 bypass oil. I have attached a market brochure to show what the Venturi Lube Filter looks like. I have also attached a Cummins engine filter application chart to cover automotive engines.

Alan,

Contact Cummins about securing a remote lube filter head for your engine. Fleetguard does not offer that filter head.

Alan I think your question was can you use it on the ISC 350 if so, Yes I run the LF9009 on our 2000 ISC 350 without any problem the lf9009 and the lf3000 is the same dia 4.668 and the 9009 is a little better than a tenth of a inch longer.

The LF9009 is backward compatible with earlier engines that use the LF3000.

The OP's 2008 knight will be an ISC 350, just like mine. Does this all apply to that motor?

ISL's were mentioned in a lot of the posts above.
