Fault Phenomenon: XCMG XKT mining truck engine runs normally, but the transmission has no input, vehicle does not move.

Troubleshooting Process:
– Checked coupling: elastic coupling spider shattered or shaft broken.
– Checked spline: spline shaft worn.
– Checked alignment: poor engine-transmission alignment.
– Checked vibration: excessive start-up shock.

Root Cause: The elastic coupling between the engine and transmission broke due to fatigue or overload, preventing power transmission.

Required Parts: Replace transmission drive coupling assembly.
