C9 engine problem

<< < (3/3)

JimCounts:
The Turbo failure is the symptom not the problem.
Cat has a major problem with their ACERT engines which use a fuel burner regeneration system.  These came into the market in late 2007 thru 2009 I'm told.   They are being sued by some fleets for the down time and other expenses on the C13/C15 engines with the same system.  See this following link:

We have had 2 turbos go out on our 2008 Contessa 425 because of the back pressure created when the ACERT does not ignite as it should.  Soot builds up in the exhaust as a result. The tech said he had seen it backed up all the way to the exhaust manifold on some engines.
Make sure they correct the ACERT issues or you will have more failures and could cause permanent damage to the engine itself.  
Cat recently developed some new testing procedures to figure out what is happening.  Evidently the ACERT is very complicated and prone to failure.
Cat says the engine light should NOT come on during the regeneration unless it is not working correctly.  
 I called Cat and recorded a complaint on my VIN number because I think this may get worse before it gets better.
