1949 F4 V8 to Mercedes diesel build thread

I made a little progress this past Saturday. I pulled the engine so I could finish bolting the new crossmember in place. When that's done I can repaint the front of the frame. While the engine is out I will change a number of leaking gaskets and clean it up really well. I will also drill the manifolds for the sender for the turbo boost gauge and the probe for the exhaust temp gauge. Tomorrow, my plan is to take my flywheel to Springfield Missouri to have it match balanced to the Mercedes flywheel and also drop my clutch and pressure plate off to have them rebuilt. I am taking three discs and four pressure plates, they told me they would look them over and rebuild the best one of each. Friday I took my six 19.5 wheels to the powder coater to have them done. I am having them coated in red to match the cab and hood since I am painting the fenders and the Ford script bed black. My youngest son is paying for 1/2 of the powder coating for my Christmas present. I will post pics of the wheels when I get them back in a couple of weeks, and of the engine when I get it back in.
Thanks, Mark

The install is looking great, glad to see someone else utilizing the MB diesel, they're cheap, plentiful and run forever.

Thanks, Fred I will post new photos as soon as I have something.
Jeff, Thanks for the kind words. I'm not sure that I can stop all the oil leaks, but maybe I can slow them down.
I dropped my clutch and pressure plate off today to have them rebuilt. I also dropped off my flywheels to have them match balanced. I should have everything back in a week or so.
Thanks again, Mark

This is a photo of the shut off valve that I made for the Mercedes engine. The Mercedes engine shuts off by vacuum. The valve fastened on the side is from the ignition switch in the donor car. The switch on the end is to complete the circuit for the starter button. This unit mounts in the hole in the dash for the choke cable. Turning on the key switch energizes the glow plugs for the diesel. Pulling out this **** closes the vacuum to the injector pump so the engine will run and completes the circuit for the starter button so the engine can be started. To shut off the engine, turn off the key switch and push in this ****.
Thanks, Mark

CAMiniTruck, Thank you for the reply. Part of my reasoning for the switch on the end of the valve assembly, if for some reason the system lost vacuum, the truck could be started just by pushing the starter button since on a pre'52 truck it is energized all the time. My concern isn't that someone could steal it, but a child or someone accidently pushing the starter button and it starting in gear. I guess I could have used a '52 starter button and energized it with the ignition switch.
Thanks again, Mark

I picked up my flywheels this morning after having them match balanced. I am really glad that I marked the Mercedes flywheel for position before I took it off. Most everything that I have read says that the Mercedes flywheel is neutral balanced, but you should mark them just in case. Well, my Mercedes flywheel actually has several grams of inbalance. Now the Ford flywheel is balanced to match the Mercedes and properly marked so I can reinstall it correctly. As soon as I get my clutch and pressure plate back from the rebuilder and I get the engine cleaned up and resealed, I can reinstall it permanently.

Jeff, Thanks for the reply. I hadn't thought about a hidden shut off valve, good idea, I will have to think on that some more. Did you remove the ALDA on your diesel? I have mine adjusted to were I think it is actually disabled. It sure woke the car up when I adjusted it. I was told, IIRC, if I leave it on and remove the solenoid over boost valve you are talking about, to just run to line directly from the pressure sensor on the intake to the ALDA. Your thoughts?
Thanks again, Mark

Chris, on my swap I used a green and white vacuum orfice from the 300SD to soften the harsh shifts of the MB trans. It really wasn't that noticeable in the car because of the rubber dampened driveshaft.
