Whaa...?! You must be magic...!
As for Mercedes, the W116 300SD service manual, section 07.1-200, clearly states,
"(Step) 7 Unscrew all engine oil lines at oil filter body, releasing clamps for this purpose."
"(Step) 8 Unscrew and remove oil filter body from crankcase (18-110)."
"(Step) 9 Withdraw injection pump from crankcase."

I tried for nearly an hour to get my pump off the first time, before I resigned myself to the fact I HAD to remove that oil filter assembly. On four-bangers, it's not necessary; but on the fives, it is.
On a related note, as I was installing the IP onto the engine going into the Jeep, I discovered that the seal around the plunger part of the ALDA valve, uh, diaphram(?) was trashed, and probably has been for some time. I wonder how it is on the engine in my '79 SD....

Neither Mercedes nor I find it necessary to remove the oil filter to change the injection pump....-Nate
