Main air filter.

[icanshootwell]

Was talking to a distributor the other day about ordering filters when i happened to mention the air filter, i take mine out and blow the dirt out with an air line, same with the cab filters. No he said, you should leave it until warning lamp shows then replace it, that way you don,t break the seal.
I checked in the maintenance manual and it sais replace when cleaned 5 times. Anybody that bales a lot knows how quick they get blocked. What is the correct procedure? I would need 3 per year if i did,nt blow them out.

Well if you’re going to run them to the point of the light coming on then the tractor will of been seriously underpowered or will have overheated well before light came on. You should never blow the secondary filter out though as that’s the last chance saloon in the system.

Blow the main filter out as required as many times as needed and replace every big service or every other depending on condition and working environment.

Err, running headers ( sorry - combines ), cotton pickers & cotton strippers in dusty conditions, we have always blown out the main air filters on a daily basis as part of the daily service
Have just finished 4 months of running a JD CS690 cotton stripper ( new this year, 500 hp engine, $1.3 million machine ) which we blew the main filter out everyday
Standard practice here, we operate in a very dusty ( a very fine talcum powder type dust ) environment.
For the record, EVERY tractor I've ever owned or operated in the past generally has maintainence schedule of replacing the main airfilter every 1000 hrs or so, & blowing it out as required . . . Check your handbook

That is what i,ve always tried to do, blow out the filter regularly, assumed that was the correct way of keeping the tractor running as it supposed to, not waiting for the light to come on and replacing it. Anyway i just wanted to confirm i was doing it the correct way.

in the 70's ( if my memory of old manuals is correct ) JI Case ( before they became Case IH, or CNH ) used to recommend washing out the air filters, & sold a detergent product for that job. You soaked the filter in the solution, then flushed it out with clear water & let it dry
obviously, using compressed air is much quicker & more convenient.


PS - you DO always blow from the inside out I assume ?

Once I blew out the outer air filter on
Our JD 2040 then next time I discovered the inner filter full of fine dust so never again,I was able to buy new filters from trade supplier

Oh crikey, my NH L95 still has the original air filter, 20 year old, never though about replacing it. That's livestock farmers for you I suppose!

Workshop manager at our old David Brown dealer said a government estate in Africa bought a fleet of DBs with oil bath filters. First time they checked them they were full of sand and oil,cleaned them out and refilled with lively clean dry sand. Knackered all the engines.

But why do I need to replace it if the secondary filter is still dirt free? The only benefit I can see maybe a very marginal improvement in air flow (but big benefit to the dealer in replacing them). I have never even tried to wash them, just blow them out as thoroughly as possible with an air line.

Those horrible Donaldson honeycomb filters have a label that says "Do not clean"!

We still do though.

Thought you meant it was a 20year old filter still in place with 20 yrs of crap in it!

Behave yourself, I would have noticed when the engine stopped running.
