05 C7 Cat air filter replacment

[lwasouth]

I would like to replace the air filter on my 05 Itasca Horizon (Freightliner)
Can anyone tell me how to do this ?

Here is some discussion about mine.

Diesel Maintanence process

Today I purchased a new air filter and installed it myself.

Purchased the filter from the local Freightliner dealer (part number FAR/114880-3 $68.28, an Eco filter).

Had a tough time getting the old filter out once I was able to get the clamps loosened on everything. Because there is so little room to move anything, I ended up disconnecting the front tubing (5" outlet end going toward the engine) from one of the middle tubes, and disconnected the 6" inlet end from the inlet side of the air filter where the air intake stack comes down the back side of the rear of the motorhome. I then disconnected the other end of that inlet tubing from the inlet side of air filter itself. Then I released the large band clamps. Unfortunately I did not figure out that you could completely unhook those two large band clamps, so I unbolted both of them from the frame mounting, them removed the air filter by backing it out toward the rear and downward to get it out. It took a lot of effort to get the hoses off the metal tubes. One thing that helped was I took my fingers and pulled the tubing away from the metal tubing completely around the edge of the tube. This helped "break" the seal that had formed from being clamped for the last three years. Of course, once I had it out and started to move the front hose over to the new air filter, I figured out that the snap bands completely disconnect at the snap fixture. Oh well, know that for next time.

Then I installed the front end of the tubing to the outlet side of the new air filter, put the clamps back in place and manuvered it back in place, reversing the take out procedure. Had a little bit of trouble pressing the front hose and clamp back in place, but with some pressure and moving around a bit, got the engine side back together, bolted the large band clamps back in place, tighten everything up. Then went to put back the rear side of the tubing and had a tough time getting one of the 6" tubes back together. Finally got things back and tighten up all the clamps.

My motorhome has the rear mud flap in place and it got in the way of moving around and seeing things. If you do not have one of those, you can move around underneath easier.

From start to finish it took me about and hour and a half to remove and replace. I gotta admit it was more work than I thought it would be. The inlet and outlet tubes are not easy to get off and put back on. I'm glad that replacement is not an every year thing for us.

I was very surprised how dirty the old filter was and how "aged" the filter element appeared after 11,500 miles. It was 3 years old from chassis assembly date. Made me glad I changed it, despite the filter meter saying everything was great.

Here's another good Journey/Cat air filter replacement thread I found helpful when I replaced my filter.

I don't know how long ago Clayton changed the air filter but I did mine a couple of months ago and the filter cost was about $120. Actual process of changing the filter was not difficult and less than a couple of hours. Dirty & dusty but not to bad.

I paid $84.06 for the replacement air filter I installed this past summer, bought it the local Freightliner dealer. This was the second one I installed on this coach and I had a harder time this summer getting the old one off and about the same putting it on as compared to doing it the first time. I am glad it is not required to be changed every year.

Thanks for the replies. It will be most helpful when I start the job

For all the work it takes to change one of these monsters I wish it was only required every 10-12 years. Did my for the first time 2 years ago with the help of a mechanic and I'm sure dreading the next change. I drive on very few dusty roads but a Cat dealer told me the paper filter can disintegrate and migrate into the engine (assuming it wasn't just a sales gimmick).

Chuck,
One thing you might want to consider is getting a replacement K&N HD air filter for your coach. They work EXCELLENT ! Better performance and mpg.......They are a fairly new product for them and I have had one in my other coach and I have many friends that have them and no one has been dis-satisfied!

I will look into that, seems like a good idea. I just replaced my air cleaner on it before my last trip. I didn't think it was a difficult job. I also just put on a Aero 5050XL Muffler and it appears that I might have picked up 1 mpg, but it will take a longer trip on flat roads to see how much it has really gone up. Every bit helps !!

I ordered the filter, according to Freightliner specs ($120.00). I got it home and removed it from the box (What a monster) Removed the old filter, with little difficulty. Comparing the old filter to the new, the new one will not fit. The new filter has 6" in and out. My existing filter in 7" in and out. Freight liner had to order according to the part number on the old filter. When it arrives I will install it.
