I think I can finaly put this to rest. I emailed a Kubota dealer for an answer.
<font color="blue">
Question:
Does it matter what engine oil filter is used on the
bx22?
I was given a filter with a part # (70000-74034 ecn) but only can find part # (15241-32090 oem) on your site and parts list. can you tell me if I used the right filter # (70000-74034 ecn) and what is the difference between the two?
Thank You
Steven

Answer:
"Steven,
The original filter part number 15241-32090 has now been replaced by part number 70000-15241.
Part number 70000-74034 is also listed as an economy replacement filter.
So 70000-15241 or 70000-74034 will work.
The 70000-15241 is identical in size to the original 15241-32090 that was made in Japan.
The last time we tried to order the 15241-32090 Kubota changed the part number to 70000-15241.
The problem with all the confusion is that Kubota has been trying to find a filter company that could manufacture a filter to their standards. Looks like they have finally achieved this.
Thanks,
Ronnie" </font>
