Good Morning All,
This is my first post as i am researching common faults and failures of the CLASS 70 engines.
I know the engines were Jenbacher gas engines designed for stationary applications, and GE took the design and converted it to diesel.
I know it had issues with vibrations causing the fuel system to leak and catch fire in their early life, can anyone confirm what the fix was for this?
I'm also wondering if there are any further issues anyone can shed light on.
I know of an operator that has a common failure of number 8 cylinder, it appears that they have had 3x of their loco all suffer the same failure, one of the engine has suffered 3 times upon first use after rebuild and test.
The failure is liner cracking and cylinder head cracking but only on number 8, all other cylinders are fine. I've struggled to find further information.
I suspect that resonance is the cause of the failures.
