[diesel_mercedes] Fuel Economy Check '84 300CD Slushbox

 

420 miles, 24MPG, much AC and 85 ~ 90 MPH traveling .

Biobor used, the clear plastic intake screen has remained clear for four fillups now, mayhap I've killed all the fungus ? .

Low fuel lamp on @ 400 Miles .

[diesel_mercedes] Re: Son's 300SD Lessons Learned

 



Conrad ;

There are at least two different electric window lifts in W126's, they're interchangeable so be smart and just go buy one  as soon as you can before they're all gone .

Bummer about the tornado ~ I nearly got caught in one in Texas many decades ago as I was riding my old L.A.P.D. Kawasaki across America, that we intense and scary .

You're right ~ working in a junkyard or on other people's vehicles is a very good place to learn .

Don't underestimate the importance of proper oil & filter changes and brake bleeding, that's 99 % of what the average DIY'er does, maybe if he talks to the Instructor he'll get the opportunity to do somethng more and tech the class....

Learning proper shop rules and tool usage is half the battle .

Working on other people's cars is good, if something breaks, it must have needed replacing anyway, right ? .

Seats here co$t at LEAST $35 so you did really well IMO .

I recently found one in a years abandoned 240D with of course the windows open and we've had torrential rains this past Winter so the entire car was pretty ripe not to mention the Palomino colored seats were dead black and covered with 1/8" of nasty toxic waste....

I spent hours cleaning with Meguiar's #40 and no one but -me- even notices the seat isn't the matching original now .

The tracks are a little tricky to remove but cleaning them out well makes al the various seat adjustments easy and smooth again .

Measure the mirror's screw separation, there's two different and they're very close, even dirty the mirror should be easy to install .

I assume the Chinese Scooter has a centerstand ? if so , take along a bit of wood and place it underneath bot feet to raise it up a bit .

Failing that, place a bit of wood underneath the rear tire when you park it on the side stand, maybe it doesn't lean enough to prevent the wind gusts from pushing it over .

If it always falls on the same side, park it 180 degrees out and see what happens .

? Are you ned here ? .

You may have heard about my endless struggles with fuel fungus, be smart and buy a large gallon jug of Biobor and use it ~ it really works and is different than all other fuel cleaners, fungus killers and so on .

Carry a spare clear plastic intake fuel screen and #2 Phillips screw driver too and CHANGE IT the *instant* you see the chunks of dead fungus that look like coffee grounds in the intake screen .

I have learned that it's possible to clean the clear plastic intake screens in the sink with soapy water, they're only $5 at Pep Boys in the PUROLATOR brand .
Good luck with SWMBO ! .

My ex wife recently told me she's still jealous of my cars and stuff, my current Sweet is smart enough to grasp that I sleep with her, not the cars, Motos, tools, trucks and so on, there's nothing to be jealous of .

Good on ya for teaching your son ! .

All those junkyard parts need to find a home before SWMBO returns from visiting her folks....


Yesterday's torrential rain (complete with at least one tornado, about 10 miles away from me) zoomed through and today was sunny and in the low 70s.  Perfect day for putting some parts where they belong.


Son has been taking Auto Tech 1 all year.  I really have expected him to learn more in school than he has--I think he learned more in a single day of taking bits of Benz apart in the junkyard than virtually all his classroom time.  (I had no idea that Auto Tech 1 apparently involves learning how to change oil, bleed brakes--and that's about it.)


At any rate, the new-to-him seat went in and the old seat-shaped-object went out.  Remarkable difference, and that was even before I put in the new seat switch.  I must say that I like working with the hung door inserts of the W126 more than the anchored inserts of the W123--so much easier and fewer fears of tearing the door insert!  The new seat both looks good and works properly in all directions.  Plus, it smells much less like a moldy wet dog.  We lucked out with that particular $20 purchase.


After that, it was an afternoon of fiddly bits for Son, while I tried to put my scooter back together.  I realize that Chinese scooters (my commuter vehicle to the train) are not the highest quality vehicles, but mine seems to have real equilibrium problems.  It keeps falling over when I park it on either the sidestand or the centerstand.  My brother is convinced someone must be pushing it over, because I haven't been able to detect a pattern, other than it always falls on the same side--onto the right side, AWAY from the sidestand.  Anyway, while I was screwing lights and bodywork back on the 50cc ~2 HP powerhouse that makes my 300D feel like a drag racer, Son swapped out the driver's side carpet, both sun visors, and started taking a closer look at how to replace some of the broken wood trim.  With just those few changes, Escargot the acceleration-challenged 300SD already started looking oodles better.  Son had less good luck with replacing the passenger-side mirror--the junkyard mirror we picked up needs to be lubed a bit better before it will fit in properly, I think.  Son did manage to remove the broken window regulator without damaging himself or the driver's side rear door.  Typical shattered plastic slider.  We'll grind off the rivet tomorrow and then hopefully, he can borrow the hydraulic press at school tomorrow for 30 seconds to peen the new one into shape.


Quick question re: window regulator.  The arm on which the slider attaches is bent into at least three different segments, each at a slightly different angle.  I could easily see that the slider needs to get bent a bit in/out to match the window slide, but should the regulator otherwise be perfectly straight?  If so, that's one more thing to add to the junkyard list for our next trip.


I'm hoping to reserve some time tomorrow for my poor 300D.  I'll noodle-up the newish seat tonight so it'll be ready to slide in tomorrow.  Then maybe some vacuum system testing.  And there's still that driver's side door seal looking mournfully at me.  


...and then it will be time to start dealing with Escargot's motor and fungus-laden fuel.  I've already added fungicide to the tank just to get the party started, so to speak.  We'll be changing all the filters after a Diesel Purge.  I guess it's a good thing that the car isn't being driven at the moment (but that will hopefully change fairly soon).

Supposedly, Brandywine Auto Center, the parent company, has been owned by the same family since 1927.  I haven't spent a lot of time digging into their corporate history, though, but I know they own/control pretty much all the big salvage yards I've ever checked for parts in the 20+ years I've lived in this area.

There's another u-pull-it in Baltimore, Crazy Ray's, that I should check out sometime.  They don't keep a lot inventory, though, and they only keep cars out there for 1-2 months before crushing them, so I don't expect they would have much vintage MB inventory.

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


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.

[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 .

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....
