Product Maintenance
- 1 The hydraulic coupling operates in the same manner as the motor. It can rotate in either direction, but it is not suitable for rapid and frequent reversing.
- 2 After installation, during the first power-on test run, it is necessary to check whether the coupling operates smoothly, without vibration, and without abnormal noise.
- 3 To ensure safe production, a mesh-shaped heat dissipation protective cover should be installed on the coupling.
- 4 When the prime mover reaches the rated speed, it must start to operate; otherwise, it is necessary to check if there is any jamming in the load. At this time, the machine should be stopped immediately for inspection to identify the cause.
- 5 During operation or shutdown, there must be no leakage from the coupling.
- 6 During continuous operation, the working oil temperature of the coupling should not exceed 90°C; 70°C is preferable.
- 7 After the first 300 hours of operation of the coupling, the working oil should be drained and replaced with new oil (if the crude oil is not deteriorated and filtered, it can be reused). After 3000 hours of operation, the quality of the working oil should be inspected. If the oil quality deteriorates, new oil should be used.
- 8 Regularly check the wear condition of the elastic blocks. If necessary, replace them. If the elastic block is damaged within a short period of time, it is mostly caused by incorrect installation and alignment. Realign it, and if necessary, use a dial indicator to measure and align.
- 9 The fusible plug must not be blocked and cannot be replaced with other items that do not have overheating protection function. When the fusible plug melts, the cause of the oil spraying must be found and the fault eliminated. Reinject the working oil at the specified filling volume, replace the fusible plug with the same specification, or pour in low-melting-point alloy. At the same time, recheck and tighten all the bolts on the coupling circumference.
- 10 Regularly check the installation accuracy of the prime mover shaft and the input shaft of the working machine, and correct it. Do not randomly disassemble the coupling to avoid damaging the seal and balance. Even if disassembled, mark the joints of each component.

Frequently Asked Questions (FAQ)
QWhat is the maximum allowable working oil temperature for the YOX hydraulic coupling during continuous operation?
During continuous operation, the working oil temperature of the YOX hydraulic coupling should not exceed 90°C. A temperature of 70°C or below is recommended for optimal performance and longevity.
QWhen should the working oil of the hydraulic coupling be replaced?
The working oil should be drained and replaced after the first 300 hours of operation. After every 3,000 hours of subsequent operation, the oil quality should be inspected, and new oil should be used if deterioration is detected.
QCan the YOX hydraulic coupling be used for frequent reversing operations?
The YOX hydraulic coupling can rotate in either direction, just like a standard motor. However, it is not suitable for rapid and frequent reversing, as this may cause mechanical stress and reduce service life.
QWhat should be done if the fusible plug melts during operation?
If the fusible plug melts, you must first identify and eliminate the root cause of the overheating or oil spraying. Then, reinject the working oil to the specified filling volume, replace the fusible plug with the same specification (or pour in low-melting-point alloy), and recheck and tighten all bolts on the coupling circumference. Never replace the fusible plug with items that lack overheating protection.
QWhat are the main functional advantages of the YOX Load Limiting hydraulic coupling?
The YOX Load Limiting hydraulic coupling offers multiple advantages including: reducing startup shock, isolating torsional vibration, providing overload protection, enabling power-saving operation, supporting slow startup with load delay, coordinating multi-machine drives, and extending the service life of both the motor and the working machine — all with a simple, reliable, low-maintenance structure.
QHow should the elastic blocks of the hydraulic coupling be maintained?
The wear condition of the elastic blocks should be checked regularly. If wear is detected, they should be replaced promptly. If the elastic blocks are damaged within a short period of time, this is most likely due to incorrect installation and alignment — in such cases, realign the coupling and use a dial indicator for precise measurement if necessary.
