Injector failures are rare on 3116/3126 Caterpillars.
What isn't so rare is the injector seat leaking (allows cylinder gasses to pass the injector and causes air in the fuel gallery which kills all the cylinders after the failed injector seat).....@ 1500 hours, the engines have probably already had that issue. Once it occurs, the injector seats must be reamed and the injectors reseated.
Exactly Frank! It was the #1 injector on the engine and when the tech removed it it fell apart in his hand. I have no idea what might have caused. Age? Lack of attention from the PO? The engines have 1800 hrs on them...
