I recently changed the water separating filter on my Yanmar 4BY2-180. The part number prominently printed in large face type on the front of the filter under “Water Separating Filter” is 120650-55010.
For some inexplicable reason, the part number in the Yanmar system for the 4BY2-180 is listed as 120650-55020. That number is printed on the -55010 filter, but it’s in small face type on the side of the filter under “Filter Element”. So the filter has TWO part numbers printed on it. The -55020 number is also the only number printed on the bar coded parts tag sticker that is attached to the bottom of the plastic in which the filter is wrapped. If the filter is sitting on a shelf bottom side down, as one would expect, that parts sticker is not visible.
So lesson learned: If you are looking for a Yanmar water separating filter for your 4BY2-180, either one of those part numbers is correct, but it may create confusion between parts and maintenance functions. Don’t ask how I know!
But here’s the real kicker: A Tugnut later told me about a 10 micron Racor filter, part # S3204TUL, that works in place of the Yanmar for half the cost. As far as I know, there’s no part number SNAFU with that one.
