Fault Phenomenon: XCMG RP1253 paver the tamping sound differs between the left and right sides of the screed, resulting in uneven surface texture.

Troubleshooting Process:
– Checked linkage: one side’s transmission linkage bolt loose.
– Checked eccentric shaft: eccentric shaft bearing damaged.
– Checked hydraulic motors: left and right motor speeds out of sync.
– Checked mechanical clearance: excessive tamper guide clearance.

Root Cause: The spherical bearing on the right-side tamper transmission linkage is worn and loose, causing the effective stroke to shorten.

Required Parts: Replace linkage spherical bearing and readjust.
