So this is why its hard to track them all as you can get the same part number today as you could before but they are different pumps. Thats just why with the current part number you must also look for date code on the box. So the Service bulletin doesn't come close to telling the whole story.

Now in the past every manufacture I know of revises the part number when the part is changed! HD used to do this as well, but for some reason has stopped and just decided to change the part and leave no paper trail it was changed!

My 2018, 100% stock 114 Fatbob is still in shop waiting on a new oil pump. I’ve actually thought about trading it for newer (2018 build date), but I’m really skeptical HD has really solved this yet.

that is because it isn't a part number, it is a casting number, take two items with the same casting number, machine them differently and you have two different parts and two different part numbers but both items have the same casting number, this is not something new, HD has been doing it for years

MoCo has made various revisions in the same casting and called them different part numbers ONLY some of the time. Other times, the part number remains the same, casting number remains the same yet the parts are different and we are suppose to look at the date code on the box. Just a **** poor way of handling it in my book.
