FAQ

1. Which equipment is the 860519889 central reducer assembly suitable for?
This central reducer assembly is exclusively matched with XCMG XP303S pneumatic tyre roller, and also fully compatible with XCMG XP303KS same-series rubber wheel roller models.
2. What is the core function of the central reducer assembly 860519889?
As a key part of the roller transmission system, it reduces the rotating speed of the power source, increases output torque, and transmits stable power to the walking mechanism, ensuring uniform and powerful compaction operation of the equipment.
3. Is this 860519889 reducer a direct plug-and-play replacement part?
Yes. The overall size, gear parameters and mounting holes are completely consistent with the original factory standards. No cutting, drilling or other modification is required, supporting direct disassembly and replacement.
4. What are the structural and performance advantages of this reducer assembly?
It features high-precision helical gear transmission, low operating noise and low power loss. The thickened cast steel shell enhances impact resistance, and the internal sealing structure effectively prevents dust and oil leakage, adapting to harsh construction environments.
5. What abnormal phenomena indicate that the reducer assembly needs to be replaced?
Typical failure manifestations include obvious jitter during equipment operation, weak walking power, abnormal gear friction noise, frequent stalling under load, and oil seepage from the reducer shell.
6. What working conditions is this central reducer assembly applicable to?
It is designed for heavy-duty engineering scenarios, suitable for long-time continuous operation in highway construction, municipal road compaction, foundation filling and other high-intensity construction environments.
7. How to maintain the 860519889 central reducer assembly daily?
Regularly check the lubricating oil level and oil quality of the reducer, replace the gear oil on schedule, avoid long-term overload operation and sudden start-stop, and clean the dust and sediment on the shell in time to ensure good heat dissipation.
8. Does the product come with matching installation accessories?
The product is delivered as a complete central reducer assembly. Supporting gaskets, fixing bolts and other installation accessories can be equipped according to customer actual needs.
