Here a a couple photos from a CAT D-398 on an emergency generator at a hospital that "let loose".  Cat engines are in some buses, so I think that makes this bus related  LOL  Jack

These were called a 6.25 x 8.00 engine for the bore and stroke (compared to a 4.25 x 5.00 for the 71 series).  Big engines, and the 398 was a V-12.  Even though Cat stopped making these engines many years ago, still alot of them running.  The 3500 series have taken the place.  But- since the 3500 series goes to 1900rpm, not the long lived engine like the 390 series.  Good Luck, TomC

With 2 rods on that bearing it looks like one or both rods lost their pistons and beat the piss out of the block.   Tom Y

Jack,

No, This engine was on an emergency generator at a hospital where my SIL works. No idea how old it was, but probably only ran during scheduled starts for testing.  My brother works for a company that installs these generators.  I know they are at their cabin for the weekend.  I will email my brother tomorrow and see if I can get any additional information.  Jack

It's probably a last ditch effort from CAT to pass 2010 emissions! They misunderstood what "clean exhaust flow meant" meant! ;D

No need to analyze this obvious problem!  It is simple someone just let the cat out of the yellow  bag!  John
