M816/NHC250 Oil Filter Installation

Hello all,

I apologize if this has been covered but I couldn’t find anything in the search bar, or in the TM’s for this.
Today I was trying to change the oil filter on my XM816 and when I went to install the new filter from Napa, I found that unlike the old Fleetguard filter, the Napa/Wix filter has a plate in the inner bore, about 2 inches from one end.
The problem is, if I install the filter with the stamped “ENGINE END” toward the engine, the plate inside hits the small clip/pin on the filter housing bolt and the filter won’t go in.
So, naturally, I put the filter in backwards and installed it just to cover the opening.
At this point, what do I do? I can either:
1. Leave it in “backwards” and run it
2. Take it apart, take the clip/pin off of the housing bolt and put the filter in the “right” way
3. Buy a different brand of filter and hope it’s built without that inner plate.
Let me know what you all have experienced on this. I apologize that I don’t have pictures. I also don’t understand why there’s a direction of installation when the filter appears symmetrical.

Thank you,
Peter

Update:
After talking with my friend who has done a lot with old Cummins engines, I will be removing the clip (which, as I suspected, just holds the bolt in the housing) and installing the filter correctly.

Find a baldwin filters ob1368 kit for oil. Amazon has it for less than $180.

Many threads on it here.

Does not include the spin on filter. Many choices for spin on from standard, heavy duty, to extended drain interval from fleetrite,wix, sames as napa, baldwin

Wix 51970, napa 1970 average $20.

$620 is crazy.....
