Question to NY 986

[Northvale PA]

I was reading your post from July where you explained a filter number mixup to you, years ago. And you replied to my post about something similar I just went thru. You explained your 2 different filters had 2 different thread sizes and since I had a similar problem, was that a JD tractor? I am still trying to figure out if my filter mounting bracket was changed out or the filters were mixed up. The dealer I use has had a couple new counter guys, the filter numbers are too close and in my mind the jury is still out. Thanks.

While you're waiting for NY 986, I'll interject- did you see where I looked up all of those numbers on shop.deere.com? That one with two numbers didn't make any sense, as the first number just went to a whole bunch of different things. The second number on it was good. I could wonder if JD is doing like NAPA and changing, or getting lower cost suppliers, and therefore getting different merchandise, and/or different/incorrect labeling?

My tractor is a 1977 JD 8430 with a 50 series engine in it. The incident happened over 30 years ago now. I went to the JD dealer to get a new engine oil filter and provided the information as I stated it. I don't know what chart the parts person had to work with but I thinik he fixated on the model and year and somehow the replacement engine part got overlooked. At the time JD made their own filters and that was all I used. Extremely identical in appearance and I did not question what was sold to me as the parts person never asked for more information. Not suspecting any pending problem I mounted the filter and it went on without issue. It blew off and the fact that oil was hitting the cab window made me immediately aware of a problem without running to the point of losing oil pressure. I compared the new filter with the previous filter and then the more I looked I could see a very slight difference in thread count and very small difference in diameter. I went back and got another filter and emphasized that the tractor had a replacement engine so a different filter resulted. Put that filter on and put around 2 gallons of oil in a 5.5 gallon system. The tractor ran without issue and the next few oil changes had me send in a sample of the old oil for analysis. The results always came back showing normal wear patterns. I always made sure any new filter matched the number of the filter known to work without issue.

As others have said JD bought a company that makes filters outside of the US and thus started a new number system for filter ID. I check to make sure any current filter number will correctly substitute for the old good filter number. As Bob has said the differences in the new filter numbering is very minor and if a parts person is really pushing I can see where a mistake is easy to make. Especially, if they are depending on some kid coming in after school to put inventory in its CORRECT location for the parts people to find.
