1 First, test the machine to confirm whether the vibration system of the compactor roller is not working.

2 Check whether the elastic drive plate between the roller engine and the hydraulic pump falls off. If it falls off, it needs to be reinstalled.

3 Check whether the compactor roller coupling is damaged. Replace if damaged.

4 Check the roller hydraulic motor for wear. If there is wear, please repair the worn parts.

5 Check whether the hydraulic pump of the road roller is worn. Machining or replacing worn parts.

6 After processing and repairing the corresponding wear parts of the hydraulic pump, the vibration system of the roller resumes work and the fault disappears.

If the fault still does not disappear after the above methods, you need to contact the maintenance manufacturer for disassembly and maintenance.
