Cummins ISC 330hp OIL

[Toby]

What I learned today. I changed the oil in our new MH with the Cummins 330 ISC. I notice that the fill stick indicated that the old oil was about 1 quart above the full line, and the book from Cummins said it would take 24 qts 0f oil. So I only put in 23 qts. The dip stick then indicated that I was several qts over the full mark. I called cummins and the tech confirmed that 24 was the right number. (I did not have the engine serial nr then.) Not satisfied I called Monaco tech and he said 20 qts plus the oil in the filter. Conflict. So I called Cummins back and gave him the serial nr Monaco gave me and told him what the Monaco tech told me. He then said 20 qts in the pan and 2 to 3 qts in the filter. I told him the filter only took about 1 1/2 qts. He then said that was right. So I went out and drained 2 quarts of new oil out of the engine. (after I ran it awhile). Live and learn, I hope its right now. s/Toby

s/Toby,
Now talk about timing. I just got finished changeing the oil in our 2004 MH and it has the ISC 330 Cummins.
when I initally refilled I put 20 quarts back and that included what I poured in the filter before I installed that. Dipstick said at that point that I needed to add 4 quarts. I put two more in ran it to check for leaks. After it setteled I rechecked and its right at the full line which I'm content with so thats a total of 22 quarts. My book says either 24 or 26, can't remember for sure I'll have to go look again but obviously neither is right.

I could not find the filter the book recs so I ended up buying a puralator. It was $27 and no shipping, just sales tax. The LF9009 Fleetguard was $36 off the internet, plus shipping from Ryder. No one around here had one. Its the same size as the one I took off, so I'm sure it hold the same amount of oil. I ended up with 21 and 1/2 qts of oil. I'll know next time to just add oil to the filter and then put in 20 qts. Cummins book is very confussing. I've yet to find the second fuel filter or the trans oil filter. I need to change the trans filter in another 2000 miles s/ Toby

I know what you mean about the expensive oil filter. I went to the local Cummins parts and they wanted $48.00 for the LF9009 so I went down the street to a local truck parts business and they had the same filter for $36.00. For the three filter (oil,secondary fuel and primary fuel)I saved $25.00 over what Cummins wanted.
As far as your fuel filter location, on my 2004 MH both fuel filters are on the passenger side about 6 inches apart.
Your transmission filter is in the housing of the transmission. There are two circular covers facing straight down toward the ground and one cover should be stamped main and the other lube.
If you are doing the first 5000 mile filter change which Allison recommends then the main filter is the one you need to change. It was a very simple process, six bolts replace the filter and gasket, reinstall the cover and then top off with Transynd transmission fluid. I think I lost maybe a quart if that when I removed the filter.
Make sure you use a torque wrench to retorqued the bolts on the cover correctly.
If you go to the Allsion online sight there is a ton of information that you can download under service tips with filter changeing instructions and part numbers.
I like doing the maintenance on the MH as I know it was done and done right. I also like to take care of this expensive beast so it doesn't give us any trouble on the road. Less expensive to do it yourself as long as your able too.
