air filter
#1

Just got finished changing the air filter for the first time since I've owned the coach. Steve was correct in that it takes about 2 hours and about all the tools one needs is a 7/16 deep socket. The hardest part for me was getting the two bands back together that hold the filter in place. You can't see what you are doing and after bumping my head a gillion times I finally got them together. It seemed that the filter was about 1/4" too large. Of course I am an old man and don't have the strength I had when younger. I'm probably the oldest one on the Forum. 1938 was a good year.
It has been a year since MOT changed all filters and the old filter did not look dirty at all. Maybe I will go two years on this one.
My indicator that tells me when I need to change the air filter will go to yellow in 20 miles. I guess I need to get a new one. Any thoughts there?

Not sure of this but 507 had the air filter indicator gauge by the airfilter. When I did an oil change at Detroit diesel dealer they were pretty adamant that the hole cut in the filter that the indicator attached too, allowed small amounts of dirt to bypass the filter.. They suggested just change the filter every year with the oil change.. I have not asked Newell about it but thought I would pass along

I clean mine yearly and change ONLY when the dirt is caked in and restricts air flow. If you don't drive on dirt roads a filter should last a long time ( My current one is 4 years old and like new inside)with yearly cleaning. Same goes for the air filter on the genset.

I don't drive on dirt roads. So you remove the filter and vacuum it out and put it back in? With a long snout one could almost vacuum the engine filter without taking it out. It is a lot of work removing that thing. Also I understand the glue breaks down after several years and you surely don't want it in the turbo. I don't think I would let it go more than two years before I put in a new one. Just my opinion for what it is worth.

I agree that the work to change the air filter is a big job, (by the way Chappell 1937 was a great year also) but proper maintenance of the engine is paramount to longevity. I have always changed it at 50,000 miles which is what is called for in the manual. By the time it needs replacing again, most all of my scrapes and bruises from the previous replacement ordeal have vanished and I can't even remember most of the curse words I used. Just part of owning a great Coach!

Chappell,
My restriction indicator goes into the yellow as soon as I run the engine on a new air filter. I've never seen the indicator go into the red. I don't pay much attention to it. I change my air filter on mileage and do an autopsy on it to make sure I don't have any filter break down. In the future don't undo the hose bands all the way, just loosen them until you can easily spin them on the hosing. Once loose, just move them back from the joint. This will save you time on reassembly. Sounds like you did a good job!

Hope this helps.........................

Steve, the hose bands were not a problem. The problem bands for me were the steel clip bands that hold the filter itself in place. Taking the filter out was no problem. Putting it back in and getting the 2 steel clip bands back together so I could snap the leaver was my problem for me. Got one fairly easy, but second one was something else. I finally did it.
Tom, after one has done this several times it probably be done in 45 minutes. I did however polish the chrome and did a couple other little things while things were out.
What is the big round reservoir of a thing to the left of the filter? Can't really see it until the filter is out. It has a couple of hoses going to it.
Larry, all the last years of the 30s were great years. Congratulations, you are one up on me.

I reread your original post & I misread it. Not sure why those were a problem. Never struggled with those.

Sorry Larry and Chappell you don't get to claim to be odd, I will be 79 next month. 1935 works for me.
