Well my pride and joy developed a serious problem this morning on the way to a job. I was going down the interstate cruiseing like I always do when I heard this loud whine and knock from the engine. I quickley pulled off onto an exit ramp, shut down the engine and coasted to the side of the exit ramp. Once stopped I cranked the engine back up and confirmed my diagnosis. I then called a friend of mine with a wrecker and had her towed home.
I now sit here and contemplating what course of action that I can take. Do I pull the engine and fix the rod and what ever else broke or do I swap this nice 300 turbo engine I have into the 240D body.I would want to keep the four speed manual I have in the car now but where will I get the Euro 5 cylinder flywheel I need to do this.

If any of you have any thoughts on my idea please let me know.

put the 300 turbo engine in it. Search for a thread from Claude Jones - he did the exact same thing you are talking about. He should be able to help you with advice concerning the flywheel. The mounting bolt holes for the manual are already in the frame for use with the 5 cyl turbo. Claude can help you out if anyone can.

I have tried looking for the post by Claude that contains the information on his 300D swap but I have not found any. I have found a Web page with pictures of this kind of swap of which I am going to include the address. He tells of some of the parts he used but not anything about the Flywheel he used. I would send him a e-mail but the article does not list his e-mail address. I think contrary to what I have read in other post on this site that this is a doable conversion.

Thanks for your feedback

what initated the dropped rod? low/no oil? oil pump failure? I've never heard of these engines dropping a rod. Did you have any warning signs?

A 306d is a small truck/van chassis sold in many parts of the world by Mercedes but not imported into the US. I have a 307d in the UK.

I'd buy that 300D and use all the parts out of it. If that car doesn't work out, there is another one just like it up here in the DC area with a 4-speed. It runs and drives, but its a real wreck and the tranny sounds like it needs new bearings. Too much trouble for me, but if you really want to do this, then the car is available for around $1k.

No it was not low on oil because I had just checked it and added a half a quart before I left. I had only gone about 8 miles when it happened. I rebuilt the engine about 70 thousand miles ago, the rods is one of the items that you don't usually change out when you do a rebuild. I had them checked out at the machine shop but they seemed to be fine so I reused them. This is not the 1st time I have seen this happen. I have another 240D engine that I am rebuilding and it had done the same thing.I think
I have now convinced my self to go ahead with the 300D Turbo swapout. I have made some contacts and the extra parts are not going to be that hard to come by.

MBJOE

When my 240D laid down it did just as you describe. It turned out that it lost oil pressure. I still haven't explored enough to find what caused the oil pressure loss.

To fit the four speed to the 617 engine, remove the flywheel from the 240D, and then remove the adapter that bolts to the back of the 240D engine. Remove and discard the 300D transmission adapter and replace it with the one from the 240D, then bolt on the flywheel. You will have to fabricate a pilot bearing because the automatics have a sort of ball on the torque converter that serves as the pilot shaft.

Your biggest problem is not fitting the manual transmission to the five cylinder, your problem is going to be the different transmission location. The five cylinder will move the transmission back a few inches requiring a shortened driveshaft and lengthened shifter rods.

Let us know how it turns out,

Larry, are you saying to bolt on the flywheel from the four cylinder to the five cylinder ?
Are we talking about fabricating a pilot bearing in the end of the crank or the flywheel ? Are stock ones roller bearings or brass bushings or ?
Thanks, Greg

I thought it was a typo and thanks for the enlightenment.

I was hitch-hiking in Germany in 1976 when a man pulled up in a delivery van type truck-no lettering on it, just a blinding polished aluminum body with the big star on the radiator grill.
I thought, "vot der flock is dis?" I am thinking...
Hey, I jumped in. I had a backpack which I had sewn a Candaian flag on it so I could get rides when displayed by the roadway. (No one would stop for an American in those years).
Turns out this man had just picked up his brand new MB van for his own business and was postively vibrating with pride and needed to show it off to someone, anyone! So I was perfect.
I couldn't understand his unending monologue of course, he knew it and didn't care, I knew it and didn't care. I was getting my very first ride ever in a MERCESES BENZ!!

But my GOD, what a DIN!!
I couldn't believe he was going to drive this throbbing hell on wheels for years to come! He is now deaf-must be.

So this must have been one of these vehicles of which you speak...?

Well guys I just got through unbolting and pulling everthing but the driveshalf and the tranmission mount. I have done this so many times that it only took me an hour a half. Now comes the lay om my back looking up to unbolt everthing else that has to be undone. I never look forward to pulling those bolts out of the flex disc, they can be a bear to get out. Oh well so much for tonights progress. Be back tommorrow with another update.

MBJOE

Don't the 616 & 617 motors use a chain driven oil pump? I seem to recall reading that chain failure is an occasional, but rare, failure on these engines. That would certainly cause loss of oil pressure and the resulting dropped rod.
