How much more power can a person get with a paper air cleaner instead of the oil bath on a JD 820?
Thanks for any info

I would say that you will pick up a little horsepower - providing you can find a big enough filter, whether it will be measurable or not could be a different story. The trick will be to find a sufficiently large filter, and finding a place to put it. Those are two very large cylinders you're filling, and they need to be filled in rapid succession due to the firing sequence of the engine. The oil bath cleaners are able to supply a large volume of filtered air, due to the large surface area of the mesh and oil inside. If you're only going to pull the tractor, you can probably get by with a paper element. If you plan on working it hard in dusty conditions, I would stick to the oil bath. Some pullers don't run any air cleaner at all, but that's a matter of personal opinion. I personally wouldn't do it, because I know how much damage even a little dirt can do, but I don't have to pay for their engines.

Not trying to start a spat here but the data I've seen favours the paper filter. A QUALITY filter removes a higher % of dirt in the wear causing size. As for restriction even the mighty 820/830/840 were rated at only 75 HP. The filter is smaller in new tractors with more HP . The lowered restriction will allow stock fuel flow to be more effiently burned. Or allow more fuel to be injected and burned for increased power instead of just more smoke.

I have heard of someone making a kit to convert the stock oil-bath to a dry filter(paper I guess?) but can't find the name and phone number for them, think it was Andrew's. Have searched but no luck. I would like to convert my "A" also. Anybody with more info???

You're probably right, G, as long as he gets a large enough filter and mounts it properly. I've heard of guys actually losing HP when using inadequately-sized paper filters on their two-cylinders. Basically it all comes down to how good of a filter you get and how good of a job you do installing it. I just question if there will be enough of a HP gain on an otherwise stock engine to make it worthwhile. I've pulled filters out of tractors on the dyno, and have usually seen little or no horsepower gain, providing the filters are clean.

The thing that may hurt the 2-cyl. tractors is the LARGE volume of air they need over a very short period of time. 4 and 6 cyl. engine would be more constant flow. I'd sure like to convert the oil bath A/F on My tractor to a dry pleated paper element.
