Over 3000 RPM is all the electronic download said. How far over 3000 is anyone's guess.

Oh that's nice-great photo! I remember a 1693-unbolted the head and block fell away in two pieces.
Or the 855 I could see through the block to right steer tire.

Where does that engine normally top out at? A 3406 is about the biggest engine in my world . . .
If they're the sort of firm that will put Baldwin filters on a mining truck, then it's not surprising they would cheap out on the wiring.

The deere dealer here hauled in a tractor similar to that two weeks ago, the complete
right front wheel set is missing-broke off. Looks like it might have been rolled.

RPM at full power is 1750, that can go up to 1950 in retard mode.
There used to be a document from the 3500 Engine Division stating what had to be done to an engine that had been subject to overspeeding. Depending on the max RPM registered it was anything from a valve/injector set to a complete rebuild.

Have to look at the other end of the rod for this failure. Again a 3516 with the block split from top to bottom (it even snapped the camshaft on that side) when a rod decided to say hello through the side of the block.
The early versions of the 3516HD engine had 2-piece pistons with a steel crown supported by an aluminium skirt. In this incident one of the bronze bushes in the crown walked sideways and started to rub on the inside of the skirt. Eventually it rubbed so far that the skirt failed and the unsupported piston crown literally exploded. At that point the rod poked out of the side of the block. We never did find the piston pin, it probably landed on the haul road somewhere.
EDIT: Some time later Cat switched to a one-piece piston. We all breathed a sigh of relief. Apparently the interference fit of the bronze bushes in the piston crown "ears" were the highest-rated fit available in the table of "limits & fits" - H7/S6 IIRC.

Don't have many details of this one but it was a very low-hours failure of one of the Wartsila engines at this power plant that generated all our power for the mine. I think it was "only" a cam follower failure but it cost Wartsila a new cylinder block.

That's a peekaboo photo-hard to find a good double thumper. Nice photo!

Oh the carnage, the nasty whine, it raises up like a cat lifting it's tail just before the fun starts.
That's going to take more than a bit of JB Weld to fix. Not much left of it.

It wouldn't be the first one that has done this. I've seen a 773 do the same while travelling down hill loaded. As usual blame the operator until they found the selector in 4th and the retarder on. Luckily an inframe rebuild was all that was required.

Engines don't last long, even on the dyno, when they are run without oil, which apparently is what this test was.

Without destruction caused by operator error, poor design, poor assembly or age.
Everyone on here and else where would be setting around like the Maytag repairman.
So when you get up each morning {rub your hands together like a fly} drink that cup
of coffee and smile to yourself knowing something has blown up trashed it's self.

What Nige said! Built the house ourselves on a paycheck 50 years ago. Car and truck 3 and 7 years old bought new for cash. And the secret is. Still married to the same lady since 1968. Never had to split our assets. d.d.
