2019 Seneca S2RV first oil change

Looking to do my first oil change on the Seneca.

Wondering if the Seneca has a primary and secondary fuel filter or not and if so where is the secondary fuel filter located?

Any other tips or tricks like the size of the oil drain pan?

Thanks ahead of time for any replies.

Although I have a 2014 M2 with a 340 horsepower Cummins, yours is a 360 horsepower. But they are the "same" engine except for the tuning.

I certainly believe you should have both primary and secondary fuel filters, my primary is mounted on the frame rail next to the left front tire, it has a clear bowl with the water sensor on the bottom. It also has a push button priming pump on the top of the assembly. But since you have a rear-mounted fuel tank instead of my two saddle tanks, I do not know if they relocated the primary fuel filter. But I am certain it has a primary somewhere. Let us know where you find the primary filter mounted, might help other owners.

The secondary fuel filter is mounted to the engine itself on the left side. It is about 1/2 way back on the engine. It has a hex on the bottom of the filter for removal. Picture attached below of an S2RV chassis another owner snapped at the Jayco factory.

As far as oil changes I have Fumoto valves installed on my engine and generator. Makes oil changes so much easier and neater. Not sure if the oil capacity is any different than mine, perhaps another S2RV owner will chime in.

The primary on the S2RV chassis is still in the same spot, on the frame just behind the drivers front tire. I will be doing mine when I get it back from the dealer, I have everything ready along with a Fumoto valve. I have read that if you tape the hose of a vacuum to the oil filler hole in the valve cover and tape off the slobber tube you can pull the drain plug and place the Fumoto valve in without spilling a drop.....I’ll give it a try so I can drain the old in gallon jugs. Listed oil capacity is 12 quarts with filter.

Here are some close up pics of the secondary fuel filter and the oil filter on the passenger side.

Thank you both for the replies from what I gather I am looking for the primary fuel filter and itís part number - I have the oil and secondary fuel filter on order already and will look into the fumoto valve.

Thanks again, the information the both of you have posted in other posts and this one is incredibly useful!

Thank you!

I found a picture of the primary filter/water separator installed on my rig. Yours may be somewhat different, but perhaps not!

Good luck, I hope you enjoy your Seneca as much as we do ours!

My 2014 Seneca holds 18.5 quarts. This is as per the manual and my three oil changes. However, I have found that 18 quarts registers full on the dipstick. I will add, Commins does have different size oil pans, I ran my engine number to verify the capacity on my engine. Hope this helps, Sam

The primary water separator is different on the S2RV chassis, it uses a Detroit Diesel one, at least mine does. I could not find good info on the filter as the pictures in the Freightliner manual did not match what was on mine. I was finally able to get a picture of the label with my phone as the label is facing the frame. The label had the replacement filter number on it and even with that number, I only found it in a couple places on the web and no cross reference to it even though it is a Racor filter. The number on my separator for the filter is R61709 and the best price I found was at https://www.finditparts.com/products...filters-r61709 but I would check your housing for the filter number before ordering. I did a quick search since mine is in the shop and couldn't get a larger picture and found one of what it looks like.

Thanks, I was able to get a picture of mine including the filter part number. Hopefully this helps somebody else.

In Cummins documentation with my dealer I do have ISB diesel maintenance and operation guide but not sure what filters make sense I would think the CM2350 (EPA13) which would fuel filter fs1065 and ff63008.

Does that make sense? Picture attached. Problem is I do not think it is correct because the part number does not match what is on the Seneca visually.

Thatís where I looked first and when I searched those numbers they didnít look anything like what I had. Remember, the motor is Cummins but the water separator is Detroit Diesel (Freightliner). The correct primary/water separator is R61709 and the Secondary is FF63009 (Fleetguard) and the oil is LF3970 (Fleetguard). The picture from your Cummins manual shows FF63008 for the filter on the motor but that has been superceeded by FF63009.

Robby, you indicated that you installed a Fumoto valve on you generator, what part number is it? I have one on the primary engine and have used them on other vehicles and the are time saving,
Thanks, Sam

According to the Fumoto website there are two possible thread sizes for our existing oil drain plugs, 1/4" NPT or 3/8" NPT. Mine was the 1/4" version, I have not actually heard of anyone finding their unit had the 3/8". But before ordering a valve I would recommend checking your generator's plug to be sure.

The 1/4" plug requires two parts, an adapter that screws into the sump, then the actual valve itself. I purchased a third (optional) component, a lever clip. The lever clip is a locking collar to make it even more likely the valve could never come open accidentally. The valves may come with the lever clip now, I had to purchase it separately when I did mine.

The Fumoto part numbers were:
Valve - F107N (The N signifies it has a nipple to attach a drain hose making it less messy, espcially if there is a wind blowing!)
Adapter - ADP-710
Lever clip - LC-10

I hope that helps!

The 8k generator in our 2018.5 took the same ones that Rob listed.

FYI, during my first oil change I discovered that the drain plug in my 2018.5 S2RV Chassis is 18mm x 1.5 so it takes Fumoto valve F104N and not the 22mm valve, so now I have to wait till Saturday to finish the job. The fuel/water filter number on the S2RV is R61709 which is an original Detroit Diesel part number and did not find a cross reference but found them the cheapest here https://www.finditparts.com/products...filters-r61709 It is pretty easy to change and I believe I got a plastic wrench in my packets from Jayco but couldnt find it so I used a strap wrench to get it open. Once it is changed there is a primer pump on top to refill but I suggest prefilling as much as you can. I did finally find some instructions for the Detroit Diesel filter which is attached here. Here is a video on changing the secondary filter I found but its pretty straight forward.

Rusty, did you do the Seneca's first oil change at 6k miles? Also, if it's not too much trouble, can I get a parts list from you? And any helpful tips you can give would be greatly appreciated. I am looking to stay on top of the maintenance schedule on the RV. Thank you in advance!!

Th Cummins recommended is 15k miles/12 months and I would never reach that mileage in a 12 month period so as in past motorhome I do all the maintanence yearly regardless of mileage and that is in November. The first service I did was on 11/8/18 and was a 7700 miles. I have attached a list of filters I have used so far. When I do the oil/filter I also do a full chassis grease, coolant level, check all hoses and lines on the whole chassis for abrasion, check leveler fluid level and brake adjustment and just a full chassis visual check. I have probably left something out but you get the idea.

Any tips on getting the oil filter out? I looked at mine and it is way up there with very little room to work on it.

Rustynuts, I have the same primary filter on my 2018 m2 chassis. When you changed this filter element did you have to prime the system or fill the bowl with diesel?
