High fluid coupling temperatures can be caused by a variety of reasons, and here are some possible solutions:
1.Check the oil level: Make sure the oil level in the fluid coupling is correct. If the oil level is too low, it may cause overheating.
2.Check the oil temperature: Check if the oil temperature of the fluid coupling is too high. If the oil temperature is too high, it may be necessary to change the oil or check the cooling system.
3.Check the cooling system: Check that the cooling system of the fluid coupling is working properly. If the cooling system fails, it may need to be repaired or replaced.
4.Check the filter: Check if the filter of the fluid coupling is blocked. If the filter is clogged, it may cause overheating.
5.Check the seal: Check that the fluid coupling is well sealed. If the seal is poor, it can lead to oil leakage and overheating.
6.Check the load: Check if the load on the fluid coupling is too large. If the load is too large, it may be necessary to reduce the load or replace it with a more suitable fluid coupling.
If none of the above methods can solve the problem, it is recommended to contact the manufacturer of the fluid coupling or a professional maintenance personnel for inspection and repair.
