Referring to large HP industrial, marine and truck engines as you go up in rated hp you add or stack balancers or you tear them up, I think that what you are seeing is mostly undersized balancer capacity and the torque convertor equiped models are absorbing some of the crank flex etc, I would like to see you make a hub to be able to double and triple stack stock balancers to test for real cause
Going from what you found with bent rods and corresponding vehicles having manual transmissions it would be interesting to see the end float of these cranks, it might as be indicating a discrepancy in spacing of components with the manual transmissions being used, causing minor movement of the crank under high horsepower applications or possibly an added harmonic indifference. I’m not very familiar with these motors but keen to Learn more
if a block needs taken apart 0.3-0.6 over dim and a stroker crank would be a cool upgrade, maybe not as rpm friendly but the boost would come on faster
Gotta love the hate...If I could afford it I'd have an OM series engine in my LT35 van...it would be cheaper and less hassle to by a Sprinter but feck that I have standards...LOW standards but standards just the same...Keep posting Luke!!
Would be awesome if you could work with fluidampr to make upgraded harmonic dampers. The stock damper is probably alowing allot of crank harmonics to build up at those horsepower levels.
I immediately thought, must be a manual… sure enough. Could it be that for these high power engines also stronger clutches are installed? And that the axial bearings can not withstand the extra pressure? Maybe the crankshaft is moving axial slightly when pushing the clutch. Look into better axial support instead of stronger rods. Saw this problem with a Volvo turbo red block. You could even see the movement of the crankshaft by eye (engine was shot)
Hey dude! The audio of your videos is at half volume.. I have to double the power on my reciever, and after i watch your video (wich i love, great content) and it skips to the next, someone in this room has go change their underware :P
Although I have never seen a pulley coming off I have always wondered about that shonky piece of junk on the crank nose considering the excellence that the rest of the engine is based around.
Just a thought, high hp, manual box would need a heavy duty clutch. Would this be wearin the crankshaft thrust bearings causing the crankshaft to move back n fwd?
@@Stale_Mahoney yes. It used to happen to Triumph 2.5 engines. I think they only had crank thrust bearings on either the top or bottom of the crank. The larger clutch, of this engine compared to the 2.0 engine, wore out the thrust bearings. The only symptom of this occurring was that it became difficult to engage gears from stationary, the crank moved so much that the clutch wouldn't fully disengage. I don't know the Merc engines crankshaft thrust bearing arrangement, so this was just an idea I had based on my own experience
@@deetesmin yeah it is not uncommon for car produseres to use the same design over many years but upgrade some parts to keep it updated. guess that is one of the times when design did not hold up with the upgrades.
Hello from Spain, I'm an owner of a e300 w210 om606 car, and I wanted to add a little more power with a piggyback but I searched online and didn't find much information about it. I looked at one of your videos about the same car with a piggyback and I wanted to ask what piggyback was and where I could buy it.
If most of these engines that had problems were manual transmissions, with letting off the throttle to shift after having them rev to a high rpm and possibly not having a blow off valve cause too much pressure in the cylinders and the rods with bend??
So basically, if your 606 is throwing it’s harmonic balancer it means it’s time to yank it out & take it all apart 😫 I’m assuming the issue surrounding the manual trans 350+ bhp is people dropping the clutch ?
It depends what life the engine had to if you gonna drop the clutch on an unopened engine with 400k KMS you should expect it 😅 but a fresh one of 150ish k KMS will hold on for a while
And I bet all the rods were bent with the crank end pushed towards the balancer? Seems like the clutch maybe damageing crank shaft thrust bearings. I’ve heard Toyota jz series engines will wear the bearings Faster if you run heavy pressure plate and start with clutch pushed in. Haven’t had any issues with my 1jz’s. Just something I heard thru the grapevine years ago
M51 head is very restrictive, 300hp is the highest hp you can achieve after expending lot of money. It’s better to drop a M57 and tune it, better € per HP. All Bmw 6 cylinders gearboxes are compatible until 2007, so you can put M57 and M57N
Bent rods may be ralated to a thrust bearings? What i mean, if it out spec, as you press the clutch it moves the crank and then the rod gets in angle and later bends it. Just saying, couch mechanic
Is it possible to have short height pistons so you can use the 320cdi crank with the original length rods? And is there a variable geometry turbo that can make 400hp without too much lag? Or do you go twin turbo?
You should work with Gail Banks in the USA he’s a top diesel tuner. Winning all sorts of land speed titles. He dose a liquid style damper that reduces the longitudinal and rotational harmonic shock the dampers for. This damper is not tuned to a single RPM. It works right through the Rev range!! I’ve contacted him and they don’t do any for the Mercedes 5/6 cylinder motors. Someone like you could link up with Banks! And fill the void of the lack of quality dampers for high power Diesel engines! That really could benefit greatly from this upgraded harmonic balancer!! Oh and I’d be your very first customer to buy this viscous liquid damper!!
Now if the rods are bent, what about scoring done on the crankshaft? Or is all the stress taken out thru the rods? I assume the now increased .100th of play, you would run along side the crank bearings?
Dale do you have pa link or part number for the liners? I'm currently tearing down a 606 that had been sitting in a shed for a while and I have a feeling that once I get the head off I'm going to see some pitting in there.
I have Cherokee Xj 2.5 td. I want to swap a mercedes engine. I wanted to know what type of engine you ride? Gearbox control unit etc etc ..... Thank you
about repairing or damage bore... i dont agree with sleeve install. oem blocks was aged on rain ,sun, snow for few years before they went into production. this is how cast iron get stiffines hardnes etc... if you replace it with sleeve no chance that this sleeve have same characteristics of material and hardness. just put bigger pistons inside and thats it.
Hey guys im gonna be honest I wanted to email you but alright hear me out. Im in the US and i love my mercedes. Im building an om606 but I noticed only the 86-95 models have the mechanical pump you require. Would one in theory, if I sent you guys like, idk 4 or 5 pumps. Would you send me 1 really nice rebuilt one? Because im broke this month and im trying to plan for around February for +600 but im researching youre pump kits/build kits. I love benz tinkerers. Its beautiful because you guys literally. find the smallest things. and it makes life perfect. simple but Complex! Engineering the proper way. The issues could possibly be due to the transmissions that arent mercedes. I seen a guy ripping an om606 on the MB 6speed. The manual transmissions cause the crankpulleys to fly off! I fuckin love you dude. People complain but bro, do u realize what kind of flex that is? You're pulley flew off. you should be proud. Thanks guys. Those cylinder sleeves. Copping those when I get the block on the stand. Thats gonna be first thing next to pump.
I don t think that the original key was designed for that much power. also the original key looks more like a guide.. the fixing of the pulley relies on the torque of crank pulley screw.

I can't find the shorter length connecting rods on your site. And can't find anything online about swapping the 320cdi crank is the shorter connecting rods only thing that needs changed to swap cranks?
