Fault Phenomenon: XCMG RP953 paver track idler does not turn, emits a sharp grinding sound.

Troubleshooting Process:
– Checked bearing: bearing cage collapsed and seized.
– Checked seal: seal failed, mud ingress.
– Checked lubrication: lack of grease.
– Checked wheel: wheel deformed.

Root Cause: The internal bearing of the track idler failed due to seal failure, allowing mud to enter, causing lubrication failure and bearing burnout.

Required Parts: Replace track idler assembly.
