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.

During continuous operation, the working oil temperature of the coupling should not exceed 90°C; 70°C is preferable.
⚠️ Keep working oil temperature below 90°C during continuous operation. 70°C is the recommended optimal range.
- 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.

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.
⚠️ Never substitute the fusible plug with non-overheating-protective items. Always identify and eliminate the root cause before restarting.
- 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)
Q
What are the main functions of the YOX Load Limiting Type hydraulic coupling?
The YOX Load Limiting Type hydraulic coupling offers multiple key functions, including reducing startup shock, isolating torsional vibration, overload protection, power saving, slow startup with load delay, and coordinating multi-machine drive. It also helps extend the service life of both the motor and working machine while reducing maintenance costs.
Q
What is the maximum allowable working oil temperature during continuous operation?
During continuous operation, the working oil temperature must not exceed 90°C. A temperature of 70°C or below is preferred to ensure optimal performance and longevity of the coupling.
Q
When should the working oil be replaced in the hydraulic coupling?
After the first 300 hours of operation, drain and replace the working oil (filtered, non-deteriorated oil may be reused). After every 3000 hours of operation, inspect the oil quality and replace it if deterioration is detected.
Q
Can the fusible plug be replaced with a standard plug or other substitute?
No. The fusible plug must never be blocked or replaced with items that do not provide overheating protection. When the fusible plug melts, always identify and eliminate the root cause before replacing it with the same specification plug or low-melting-point alloy, and retighten all coupling bolts.
Q
Is the hydraulic coupling suitable for frequent reversing operations?
The hydraulic coupling can rotate in either direction, similar to the motor it is paired with. However, it is not suitable for rapid and frequent reversing, as this may cause damage or reduce the service life of the unit.
Q
What should be checked if the coupling does not reach operating speed after startup?
If the coupling fails to reach operating speed when the prime mover hits rated speed, immediately stop the machine and inspect for any jamming or blockage in the load. Also verify the installation alignment of the prime mover shaft and the working machine input shaft, and correct any misalignment found.
