JD air filter cleaning

My JD has a paper air cleaner element. Acording to the cleaning instructions I can use a JD filter cleaning solution with water, or non-sudsing detergent to water. What have some of you with paper air cleaner elements use for cleaning with good results, or just blowing with air is ok. Stan
 

Follow the instructions and use the washing solution. I know a lot of folks DO just blow them out with compressed air, and I'm guilty myself occasionally, but there is a very real risk of blowing holes in the paper element when using compressed air.
 
How many times a year does the filter need cleaning?

How much will it cost to rebuild the engine if it gets "dusted"?

Frequent replacement sounds good to me.

I clean filters once or twice with a blow gun designed for the purpose then toss them.
 
I've used sudsing detergents a few times, cap of tide liquid in the bathtub. Generally I just use the hose and lots of clear water.
 
The filter test technician tested washed elements and they passed, so yes it is OK to wash them, but I still don't embrace the practice. I thought it pretty tough to keep the dirty wash water from migrating dirt from the outside to on the inside, and after washing thought the "clean" filter looked pretty dingy. We never washed any filters but periodically blew them out at the vehicle test facility. I also use the "not recommended" air compressor method but have occasionally tried a leaf blower which is less likely to blow a hole. I've never seen any dirt accumulation in the secondary filter so I'm going to continue blowing out the filters.
 
A lot of dry air filters can have a safety element installed inside the main filter. I think I read somewhere(Donaldson probably) that they can be cleaned 2 or 3 times only and when blowing them out, not to use more than 40 PSI and don't put the blow nozzle right up to filter. Dave
 
Bless those safety elements. Changed many 806 diesels to the 856 filter canister. Could not get farmers to clean their oil bath air cleaners and then when the dry one was introduced could not keep them out of them. Beating on tires was probably the meanest treatment. A working air filter restriction gauge and leave them alone until scheduled maintenance periods . When IH put that improved precleaner hunk of tin in front of radiator you could run them for many many hours. Installed a ton of them also. Another thing was the hose clamp that would not dig into hose and loosen up, original ones ruined a few engines also. Really hard to get all the dirt out of an engine that has shelled out due to dirt ingestion.
 
I just use air, directed at an angle to the filter. I don't recall ever blowing a hole or seeing a dirty inner filter. I'm also guilty of using the 'bang it on the tire' method, but when your combining in extremely dusty conditions plugging the filter daily, it keeps you going. I do occasionally use the soapy water on the cab filters. If you don't have an inner/secondary filter then I would use extra care cleaning and replace more often.

I haven't replaced the paper filter on my Nissan UD 1800 Diesel truck in 5 years. A good washing with clear water under well pressure keeps it clean and my engine working properly. The truck gets about 200 miles a day twice a week on a route ,50/50 dirt and pavement roads. Dirt roads here in Arizona are just that,Dirt.Lots of dust.
 
Be real CAREFUL if you wash them ! JD even says to only do it a few times and then chuck them.

I once had to rebuild a very well cared for JD 1020 gas with low hours and this all was because the owner washed his air filters. This opens up the pores !

I am guilty of blowing them from the inside out but I do replace them regulary.
 
I will third what xplor and pete23 have said. The Caterpillar manual that came with my truck was very specific and direct about not opening the air cleaner unless the intake restriction indicator said to. I ran the truck for two years in a lot of dust and it never indicated a change and continued to run very well. Follow the instructions for cleaning. use air only if you have a pressure regulator and gauge. Clean it only at correct intervals which are assuming a lot of hours during work season. If you are not working it you are not really taking good care of it by servicing the filter.
