[diesel_mercedes] OM617 Turbo Removal

 

Uh, oh Mark ;

I wonder if I did it wrong ? .

I -do- remember reaching the inner 17MM ATF nut was a real bear, I posted a photo of the long jointed 3/8" drive extension and socket I cobbled up to do the job, I had to loop a wire around it to get it in there because of the tight clearance between the oil filter cannister and injection pump.........             

It's been a year or two and I now have a pump I replaced all the delivery valves in and sent out for be adjusted on the BOSCH I.P. pump bench.... ($500 !), I've been dragging my feet on the job for a while now .

I'm not <magic>, I'm just not proper;ly trained on Mercedes Desels so I do whatever I think is necessary to do .

That rear under bracket was a real pisser too .

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....
