Engine:
All G3600All G3600 Engines are equipped with a sophisticated detonation control system. The system is designed to provide detonation control for selected cylinders. However, the system is also capable of detecting other unusual structural vibrations. The system can detect both detonation events and irregular mechanical events.Any alarm that is generated by the system must be investigated. The cause of the alarm must be identified and corrected. If detonation is detected, follow the instructions in Troubleshooting, RENR5910, "Detonation Occurrence".If a root cause of the detonation is not found, proceed with investigating the mechanical system. Look for loose fasteners, discoloration that is due to overheating, and any indication of mechanical impact.A typical inspection sequence is to remove the crankcase side covers, the camshaft covers, and the valve covers. Check the valve lash. The inspection process has identified the following problems before the problems could cause a more serious situation: maladjusted valve lash, spalling of the cams, broken connecting rod bolts and other mechanical issues.
