Filter change interval questions

[Gary.Jones]

I just watched NIRVC's 2019 Anthem video to see if I would learn something and was surprised to hear Angie say two things dealing with filters. The first was that she said that the Meritor Air Dryer filter should be changed yearly. Similarly, she said the Cummins engine air filter should be changed yearly.

Now, I have never heard of those two filters being routinely changed yearly. I didnt change them on my Anthem (did the Cummins air filter but only because the air pressure indicator was high from the time I bought the coach and never got any lower even with the installation of a new air filter)(no one could find a restriction in air flow, but the sensors always showed the filter needed to be changed, even upon delivery) and never read anywhere (I dont think) of a recommended yearly change. Have I missed this?

Gary, personality I replace them every two years. The air dryer would probably be good for three, but I change at two. I just replaced the air filter and you could see it was a little dirty, but not bad. I did have an extra Entegra screw floating around in it.
They also recommend oil change every six months, but the way I think most people use their mh, even full timers, why would I change oil in the fall let it set five or six months then change oil again in the spring.

Love Angie, but her presentation is scripted. Follow the maintenance schedules as recommended by Spartan. My air dryer filters make it 3 years in our humidity.

In a spartan class we were told the air filter yearly. Reason was they are put together with glues. Is for some reason the glues come apart by by turbos.

Air dryer filter best to change every year for sure. On trucks i have I will change every 6 months and they have moisture in them. Good idea is ever 6 months screw it off check if you have moisture on the mounting face change it if not screw it back on. Don't let it go to long or it will like like this one . Used truck I bought and did not get changed until i did it. Got to buy new whole new dryer

I was told that Cummins requires the air filter be replaced annually to maintain warranty. Heard the same story about paper and glue failing can cause filter media to be injested. The new one installed by NIRVC came enclosed in a plastic bag inside a corrugated box, and Troy said they do that to protect from moisture while in storage. You would think a $250.00 filter would be made "better" than that.

Our MH gets used 4 months a year. I have never had moister in a filter at the end of 3 years. They have to be used to get like that. 3 years X 4 months= 1 year. JME

Does that $250 include installation? Bought filter for Cornerstone for $105 from filter warehouse, same filter as original.

Turbo doesn't cause the glue to fail!

What you probably heard was if the glue fails, and parts of the filter gets sucked into the turbo, it could be destroyed.

I have the air filter and aur dryer services every couple three years, usage depending.

I will save someone the trouble of correcting you seeing as I'm here now. That poster quoted the same as you that if the glue fails, peices of the filter will ruin the turbo.

Now the reason I am posting is to mention that if you change your Cummins air filter annually instead of using the guage you will in the life time of your engine have more dust enter. Everytime you monkey with the filter a tiny bit of dust sneaks in.

Poster said Turbo causes glue to come apart.

I'm out!

Ben the way I read it was “bye bye turbo”.. not by by turbo.

You are correct that turbos don’t cause failures anymore than tires cause failures when you run over a sharp object in the roadway.

Fleetguard recommended changing the filters every 24 months as the glues binding the filtration media degrade over time. For some reason, Fleetguard decided that 24 months (calendar, not usage) is a good time to swap critical filters.

As far as Cummins is concerned, any debris found in the intake tract is grounds for Warranty Claim denial based upon “sabotage.”

If you’re worried about getting debris into the intake tract when changing a filter, it’s time to consult with a mechanic on how to avoid this.
