Re: [diesel_mercedes] OM617 Turbo Removal

 

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."


https://handbook.w116.org/Engine/617/07_1-200.pdf


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....

I thought we did much better than I thought we would.

I did find one broken spring, but the seat overall is in much better shape than what I have now.  Also, it's been surprisingly therapeutic to clean all the grime off the seat and watch the original color come back into view. I pulled it from a white 240D; even after all my cleaning, it's still a greenish-off-white?  Weird color, but nice and firm.

> Maybe stuff some pool noodles  in the 240D seat you son bought as a prophylactic measure.....

I was thinking the same.  The 240D seat is for my 300D; Son got the fully functional Palamino W126 power seat--which also cleaned up nicely and installed easily.

> So far, of the dozens of used injectors I've bought / scavenged/ found, only two were any good so I'd not pay for them apart from buying a set of spares to be used as cores....

That's my intent.  I expect I'll have to rebuild any/all of these injectors, but from the ragged idle of my engine, even with nicely adjusted valves and clean fuel filters, I'm guessing my current ones aren't in great shape, so I figured I'd rehab these, put new nozzles on them, and swap them in.

I'm in the greater Washington, DC area, which is fairly affluent (overall, though there are still plenty of pockets of poverty) and supports multiple Mercedes-Benz dealers.  There are a lot of MBs zooming around here, though older diesels have disappeared fast since about 2012, which was the peak of the greasecar/biodiesel fad around here.  You still see a few for sale on Craigslist, but there used to be 10+ available at any given time. Prices for these cars have also dropped around here, but that could also be because the cars showing up for sale are really thrashed and/or rusted out.


The u-pull-it yard is part of a large conglomerate of 6+ yards.  I think the best parts are stripped by the company before anything is ever put out for the scavengers, and only cars that are either (1) 10 years or older; or (2) severely damaged (i.e., fire, massive collision) get placed in the u-pull-it yard to begin with.


...and in all of that inventory, there were literally only 2 ironhead diesels, both of whom got placed on the u-pull-it lot in August 2018.  I expect them to get hauled away and crushed most any day, which is why I'm considering a second rescue mission there to grab parts before they disappear for good.

Nice work!


Yeah, I would go back for the IP (which requires the removal of the oil filter housing/assembly, a messy, messy job).  With two OM617s in the house, it will be worth it if you're planning on keeping them for a while. You can always get your money back, and more, it you wish to sell it later.


As for the turbo: Maybe, if it's the earlier one that doesn't have that blow-off valve thing.  My experience is that the turbos in the yards are quite worn.  Still, it might be good to have a core around.  Maybe you'll get lucky and get one that's recently been rebuilt.


Where are you that W123/W126's are showing up in salvage yards?
