Fault Phenomenon: Dynapac F1800C paver conveyor chain jumps teeth, drive sprocket teeth become pointed.

Troubleshooting Process:
– Checked sprocket: sprocket teeth severely worn, pointed.
– Checked chain: chain pitch elongated.
– Checked lubrication: lack of lubrication.
– Checked material: insufficient sprocket hardness.

Root Cause: Long-term wear between the conveyor drive sprocket and chain, combined with chain pitch elongation, caused the sprocket teeth to wear down, resulting in poor engagement.

Required Parts: Replace conveyor drive sprocket and chain.
