HI Tmoose,
The cavitation damage noticed on the journal bearing was the known "half moon" scratches an some other scratches. The remarkable and obvious cavitation pin hole damages was noticed on the crank pin of the engine.
Hi,
The engines are V18 with 320 mm pistons. So they are big engines with 720 rpm. Do the lube oil viscosity, flow, temperature or pressure have a direct impact on the cavitation on crank pin.
Did anyone experienced anything like this?
Thanks in advance.

No, the engines are supposed to run continuous but depending on the power demand (at lower demand) they are turned off and as soon as the power demand increases they are turned on.
The lube oil is cooled and the maximum allowable temperature is 65 degree Celsius.
Hi,
Since two years ago we experienced, on different V18 diesel engines in our company, pin hole damages on the crank pin of the engines. It is suspected that the lube oil pressure drop to the point that cavitation occur always at the same place. These damages in the engines occur every time at...

Hi,
Sorry that I'm intruding into another topic. But you had started a topic on "Damage by Cavitation?" in 2008.
Because we are experiencing kind of similar damages on our diesel engines, I would like to ask if you have resolved the problem that you were experiencing
and what was or...
