4x20 air filter alert

[Cidertom]

Manual says (paraphrase) don't touch the air filter until the fault alert happens. I went on and changed it (Primary) without the fault. To say the existing filter was loaded is an understatement. I checked the restriction alarm and it worked. I'm thinking I should have changed it last year by the amount of /caked/ dirt on the filter. Just a heads up.

I had the same experience. Secondary filter looked good along with the piping leading to the turbo. I took time to remove the air box and initial intake duct and clean them up well, firm up all clamps in the system and replaced both filters while I was at it. I've been forewarned by a couple diesel mechanics that maintaining the air filtration system is more important than even the lubrication/oil.

SOP for me on my Kubota's is cleaning the primary intake filter every day when farming and changing the secondary yearly. Fuel is expensive.

Part of regular maintenance to keep that primary filter cleaned out. Compressed air from the inside out Carefully!

Interesting. Kubota uses a Donaldson type filter on the large frame tractors that's washable instead of dry.

All good points. I usually follow the manual, which in this case has a 'black box warning' :"Service filter elements only when red signal is in view in the instrument panel".

On my old 4300 it was a gauge I could see, and serviced when it started to creep up.

Most of this post was to alert others who did as I did and follow the manual. I'm going to change this to end of season at the latest. I do dump the dust unloader frequently.
