Solution to front drive failure of Cummins diesel generator

We summarize some precursors of generators and solutions to corresponding problems.

Corresponding performance: crankcase part can hear knocking sound, knock sound from small to large, finally connecting rod bolt completely disconnected or broken, connecting rod and bearing cover thrown, body and related parts break.

Treatment method: Tamping cylinder is a destructive mechanical failure, in addition to the tamped cylinder caused by the valve drop cylinder, mostly due to the loosening of connecting rod bolts.

Corresponding performance: When the hidden crack of crankshaft neck shoulder of diesel engine is caused by fatigue, the fault symptom is not obvious. With the increase of the crack, the engine crankcase produces a blunt knocking sound. When the speed changes, the knock sound intensifies. With the increase of the crack, the engine crankcase produces a blunt knocking sound. Black smoke came from the engine, and soon the knock gradually increased, the engine shook, the crankshaft broke, and then the fire.

The solution of diesel generator front drive failure

Treatment method: engine crankcase abnormal sound immediately stop inspection

Corresponding performance: When there is a hidden crack in the flywheel, it will produce a hoarse noise with a hammer. When the engine is working, the flywheel will produce a knocking sound. When the speed changes, the noise will increase and the engine will tremble.

Corresponding problem: Flywheel fracture

Procedure: Close the check immediately

Corresponding performance: Diesel generator produces blue smoke, fuel oil or speed instability phenomenon. The speed of the diesel engine is not controlled by the throttle, rising fast, until it exceeds the rated speed, the engine emits a lot of black and blue smoke.

Treatment method: stop oil, gas, decompression, etc.

When using diesel generators, we should know how to care for and maintain diesel engines. If we understand the characteristics that some of the precursors of diesel engines represent, we can better prevent some of the unnecessary things from happening.
