Oil Filter Adapter - O-rings

[SnowDrift]

I ordered the wrong oil filter adapter o-rings. Apparently those for the HMMWV are different from those of the truck adapter.

The one on the left is from my truck and the one on the right is the donor HMMWV.
Is 23500360 the correct number for the center bolt on the left, as well as the groove down inside the adapter, which is also for the bolt?

It doesn’t matter, those seals always leak anyway.

Mine were originals, to my knowledge and hadn't started leaking. I guess I must have done something wrong.

I never had a non-leaker on 6 vehicles.
How'd you do it?
What'd I do wrong?

Not sure, honestly. Oil lines leaked, but adapter didn't.

Per the dealership:
12559583 - Upper
12559584 - Lower

Being shipped, so we'll see how they work out.

12553685 is cast into my original truck adapter
12338780 is cast into the AMG adapter I have



Large O-ring from dealership is 12559095 for the K series.

AMG o-ring is different.

Thanks for the part numbers. What is different about the AMG o-ring? Any visible differences in the two adapters?

Picture in post #1 doesn't show it well but the offset is different.

AMG doesn't have the locating tab that fits up into the block either.
