Thanks for the info Pat.
Yes, I could have done that but I would have learned nothing(and came home empty handed). I've learned a lot from the replies on this forum and the research
this led me to do.
I learned that Kubota has superseded the oil filter
for this engine 2 times, the first was 70000-15241, the 2nd was 70000-74034. The 15853-32430 is for a different series of tractors but will fit this engine. Each is a different physical size, the last one is tiny compared to the first two and the OEM (2.65 dia X 2.51 height vs 3.12 dia X 3.3 height). There's no way I would put it on my engine, it just has to have less filter material than the OEM I am using now and it's only 3 or 4 bucks cheaper. I have a Kubota L4300 tractor and Kubota did the same thing with oil filters for it, the current
one is 1/3 smaller than the original. Kubota parts
are not cheap
up here, I'd pay the extra 3 bucks for the OEM filter rather than use the Kubota tiny one.
I also learned there is a tremendous difference in quality of filters, and with outsourcing by engine manufacturers an OEM product this year may be different next year, with resultant quality questions. Some filter companies make their own filters and the quality is always good. I also learned that bypass filtering is really the way to go with a diesel
but it's way overkill with my situation. I learned a lot more about diesel
oil, lube systems and filtering than I knew before, so it's a good thing.
I'm not trying to slag OEMs, I just want the best filter possible for a reasonable cost, if that's the OEM then I will stick with it. But I am pretty sure there are filters as good or better than OEMs with consistent quality year after year at a reasonable cost. Thanks again for the input from you and everyone else, it's appreciated.
