Well thats going to take a little more than just duct tape and JB weld. Last one I saw come apart like that was a M-11 in a R75 gleaner. made a few squeaks and then a loud bang and puked a rod out the sided of the block, and put a hole in both sides of the block in the process. One heck of a mess. If pushed the dealer gave us a turn around of 4 days to drop in a new motor, it was under warranty so I don't know what the cost would have been. From What I see you should be able to get a reman for under $15,000 not sure about a new one from CAT. My experience is that that Cat yellow paint is darn expensive.

Hope your able to get it fixed up quickly

Maxxforce engine's are common rail now no? Thought HEUI's were nothing but a bad dream now.
I didn't think they changed, that's a good question. Parts guys are still saying don't buy Maxxforce engines they are a nightmare.

Does your 780 have the Mercedes Don? How is that engine in your other truck? Ours is great so far, wish it had an Allison.

I like to think of it as owning two Mercedes.;)
Yes, combine has a 16 liter V8.
Claas going to 15.6 liter 6 cylinder Mercedes next year in the 780.

Truck engine works well, has a locomotive sort of sound and feel to it, the sort of power curve where you'd think an Allison wouldn't be a big an advantage, but it still is.:)

Looks like an I6. It also looks like an awesome engine!!

Mercedes also revealed its new 15.6-litre, inline,

Mercedes also revealed its new 15.6-litre, inline, six-cylinder engine, the 0M473, offered in both the Arocs and the Actros. This is Mercedes' fifth new truck engine in less than two years. It completes Mercedes' Euro-6 engine range, which boasts a smooth progression in terms of both swept volume and power ratings, from 154hp to 617hp.
Available only as a Euro-6 engine, the 0M473 supersedes the 15.9-litre V8 0M502LA engine in the top Euro-5 Actros. Whereas the V8 comes in 503hp, 542hp and 590hp ratings, the new 0M473 ups the ante, to 510hp, 570hp and 617hp, with rated speed cut from 1,800 to 1,600rpm. Torque is better too, 200Nm more than the V8, with the 617hp unit reaching 3,000Nm.
Although Mercedes has no plans to gatecrash the Swedish 700hp-plus club, head of truck product engineering Georg Weiberg said we can expect to see more than 617hp from the 0M473 once testing has proved that higher power does not jeopardise durability.

The key features of the new engine echo those of the 12.8-litre 0M471, namely twin overhead (hollow) camshafts and Bosch/Daimler amplified common-rail fuel injection (dubbed X-Pulse by Mercedes). The latter provides injection pressures of up to 2,100bar along with rate shaping by means of pilot, main and post injections for each firing.
Unlike the 12.8-litre engine, this new 15.6-litre unit uses turbo-compounding. Its Holset turbocharger is followed by a second turbine that extracts the thermal energy from the exhaust stream and feeds it back to the engine's crankshaft via a hydrodynamic clutch (fluid coupling) to supplement output. But the turbine is spinning at approximately 60,000 rpm, so two stages of reduction gears are needed to bring the speed down to match the engine's 1,500rpm.
Turbo-compounding only pays dividends if the engine is working hard, when there is lots of energy to be harvested from the exhaust. Daimler reckons turbo-compounding gives fuel savings of around 2% under high load conditions. So the 0M473 will shine at high weights and in mountainous terrain rather than taking life easy at 40 tonnes and 1,000rpm on the Ml.
Like its two smaller siblings in the new OM engine range, the 0M473 has a powerful integral three-stage decompression brake, better known under its proprietary 'Jake brake' name from US-based Jacobs Vehicle Systems.
NOx reduction is handled by cooled EGR in the engine, plus SCR exhaust-after-treatment. The 0M473's dry weight is quoted as 1,284kg, which we understand to be about 100kg more than the current 15.9-litre V8. It is also 150kg more than the 12.8-litre 0M471, which has ratings up to 503hp.

Um, maybe.
I'll look.

Well, sorta.;)
Don not quit the photos I was thinking. Bit of a Aussie thing but when you work with a useless prick that seems dose no wrong in the bosses eyes the saying is there got photos of the boss. These photos involves such things as goats and pigs.

I thought maybe the freightliner had one over you and why it is still parked at your farm.

Nice photo buy the way.

Thank you.

No, truck has nothing on me.;)
It was barely used this fall, the cart and properly running truck doing 95% of the duty.

Agree.:(
After spending 30,000, roughly half the value of the truck, here's how it works:
- The oil pressure light flashes intermittently yet gauge indicates pressure fine.
- Cruise can not be activated if engine braking switch on.
-When you do get cruise on it turns out it's not cruise at all, it's only a throttle lock. Allison Automatic, far and away the best part of the truck btw.
- Check engine light flashes mainly at high engine speeds, don't know why.

Took it back, got the nothing we can do line.
I give up.:(
Hey Don, i had a similar issue with oil pressure. took it to a cat service and was told absolutely do not run 0w40 in those engine mine is a 3406. running the 15W40 added at least 15psi when oil was warm. also they changed the oil sensor out because it was reading about 20psi lower than my mechanical gauge. Just a thought but this fixed up my engine light blinking with low oil pressure even though the gauge was showing perfectly fine. mine would also only blink when at higher rpms, never when idling.

That was when my dad was still active, he cut and hay wired (literally) an old tractor inner tube to the spout.
It did work well, and sure beat the scattered discharge the original spout had.:)
Not important when you dump in a cart but for trucks it's great.

A friend refers to dumping in a cart like pissing in a lake.:)
Really don't need to be all that accurate.;)

Nothing new there, Claas had a lot of issues with C9 motors about 3-4 years back putting pistons through the side of the block, friend had one on Demo did that, went up in smoke. was put out, 100K damage they were told by the insurance company should have let it burn :(
This post is pretty old to reply too. I should have looked this up earlier. About two years ago, my C9 in my 2009 570R almost blew up. I got lucky I guess. If I would have ran it about 2 minutes longer it would have blown up and burned the combine. Likely. What happened was that it blew a hole in the top of a piston. This caused the crank case to become pressurized, and it almost instantly blew all the oil or almost all out of the crank case breather tube. I was unloading grain at the time and the cart driver noticed a lot of smoke and I was able to shut it down on time. I added oil, and tried it again, but it sounded terrible. I had the dealer come out but they did not have any good answers, and wanted to do some high idle tests, which would have clearly blown the whole engine. I took the engine out and apart myself, and I found the problem. A wrist pin snap ring was not installed correctly at the factory as I found it in the bottom of the oil pan slightly bent, but now wear on it at all. This allowed the wrist pin to move and rub against the side of the cylinder. This caused the rings to fail and that caused the piston to finally fail and blew a small hole in, which pressurized the Crank case. The engine only had about 1200 hrs on it at the time. The combines warranty had expired and CAT would not stand behind their engine. I put in one cylinder and piston and rings and a new head gasket. That was all. I have about 2500 hours on the engine now and it still runs great.

Well this thread really gave me a start but not as bad since I noticed the date . Mine has about 3000 hours so I guess build defects should be out of range .

My grandpa had 2 Claas with a CatC9, one blew up at 100hrs right on the field.
Cat technicans set up a tent over the combine, changed half the engine and it was ready to go again within 72 hours.
It was during a weekend and the techs had to drive atleast 3 times to thoier dealership (600km).
Luckily it was within the warrenty (1st year).
