One of the most frustrating things about filters is that just cause something cross references to another filter doesn't mean they perform the same. For example, the OEM spec a CR 5.9 Cummins fuel filter is 7 microns, however many auto parts store fuel filters, that cross reference to the OEM filter, are 10-22 microns, which at 25,000 psi of fuel pressure can lead to issues. On the other hand the Baldwin PF7977, which crosses to the OEM filter, is 5 microns.

Can he use the B50 on the mount he purchased? What filter or filters do you like in this application? I'm thinking a 10-15 absolute micron rating since the wear metals (5-7 micro size) will show on a UOA. But I could be missing something here................

I wouldn't go so far as to say it would be useless cause the other betas could be better than the full flow. If it isn't practical to return it I would run it for an OCI and see how it goes via a UOA.

Yes, the thread and baseplate are the same so it will fit.

Thanks. Hoping they're not too bad

Picking up where we left off

Okay, as I'm working on some of our heavy equipment, I look over the hydraulics and my mind turns to the oil bypass filter stuff still in a box.

Where does the time go?

So in the interest of getting things started again, here is some oil p*rn to enjoy










Note the hole in the bypass filter is NOT offcenter. It is centered on a plug recessed about 1/2"-3/4" down the hole. Optical illusion

Oh...and found out that even a PIC with the word "bypass" and "hole" as one word gets filtered out when run together So it's renamed now, LOL

99% at 45 microns. And I had bought a couple of them because they were cross referenced to the B50

P550050 - LUBE FILTER, SPIN-ON BYPASS | Part Detail | Donaldson Toolbox

What do you think? Run them, or wasting my time and get the B50 instead?
