Fault Phenomenon: XCMG LW500 wheel loader engine runs normally, but the vehicle does not move when gears are engaged.

Troubleshooting Process:
– Checked torque converter: internal turbine damaged.
– Checked connection plate: elastic connection plate between engine flywheel and torque converter broken.
– Checked input shaft: transmission input shaft broken.
– Checked control valve: control valve completely stuck.

Root Cause: The bolts on the elastic connection plate between the torque converter and engine flywheel sheared, or the plate itself broke, preventing power transmission to the transmission.

Required Parts: Replace torque converter elastic connection plate and high-strength bolts.
