Yanmar Air Filter Elements

[California]

FWIW. Some air filter elements for YM240/YM2000 and similar.

Back row from left:
Yanmar #124295-12560. 4.5" ID, 7.5" OD.
Yanmar-USA shipped this larger element (7.5 inch) when 'element for YM240' was requested.

Yanmar #124450-12510 (the # in YM240 Parts Manual). 4.5" ID, 7" OD.
NOS filter I found on Ebay.

NAPA #2297. 5.5" ID, 7" OD.

Front row:
AC #A127C, a replica of the Yanmar 124450-12510 behind it.
Found this on my YM240 in 2003.

All the filters except NAPA are 2 3/8 inches tall. The NAPA is more than 1/8 inch taller. The enclosure lid wouldn't seal so I took it back. (Also - this photo shows the NAPA filter has less surface area).

The NAPA filter for the YM146 is a drop in replacement. Fits nice.

My records show a NAPA 6022. It is 2.25 tall and 7.44OD. It will pass 170cfm. The 2297 will only pass 25 cfm.

Question here, if the lid dosent sit all the way down cause the element is taller thats not where dirt would get sucked in, that just means it wont pull through the intake hose but from the outside air right?

The AC filter fits? I was thinking that the only one that fit were yanmar?

Now heres a question on the pic you posted on the other thread about your filter element. I knew you could blow it out, but i heard that you could wash it, this just says to blow it? I have just blown mine out. I was thinking that at 10 hours it said to blow dust out of the filter.

That air capacity sounds better but if it is 1/8" less tall than an OEM filter then I would expect dust to bypass between the filter and the lid. Wayne (LMTC) and I think Aaron said they discovered short, non sealing air filter elements in engines that needed rings far too early.

I'm no authority on this stuff, I'm just sharing what I have read, mostly here. That low volume too tall NAPA element in my photo was one I saw recommended in this forum so I bought it. When I compared it with these other filters (and took this photo), I concluded it wasn't suitable.

True, but as noted over in the other thread the filter enclosure already loads up fast with debris when pulling from in front of the radiator. I think pulling from behind the fan (through that gap) would gather even more debris and plug the element even faster.

The AC filter fits?

I think at one time AC made this correct element, but abandoned production long ago. Its dimensions are identical to OEM.

I don't know the answer - I'm just sharing my observations.

What does it look like?

I used the 6022 for several years. I just made a gasket to take up the minor height difference. Yes, I have washed out Yanmar OEM filters many times. Soap and water, air dry. I also have made foam socks to go over some of the filters and sprayed filter oil on them. That really extends the life.

Another photo of the old-stock Yanmar 7 inch element originally specified for YM240/YM2000, and Yanmar's modern 7.5" diameter filter element.



The filter paper on the old style has a strange texture like it was sprayed with concrete. I don't think it is the washable element however, because it isn't heavier than the modern filter like Mark described.

I wonder how old that box is, since it is from before their red trademark color. Maybe 1970's?

I got two of the NOS elements on Ebay for almost nothing. I presently use the YM240 mostly for backhoe work so it is taking a long time to see any soiling on the filter element. The one in the photo is unused.

The current model element, upper element in the photo, is used, washed, set aside for backup so that's not its original color. I think it was tan.

I like the foam sock idea. My old Jeep Wagoneer came with a factory foam ring around an element like these. The foam loaded up quickly when running dirt roads and it was simple to shake or blow out.

I agree washing and rotating among a couple of OEM filters makes sense. Especially if they get covered with mowing chaff after a few hours.
