Hanna hydraulic pack issue

[Robert2181]

I have a Hanna hydraulic pack (80' conveyor) that is making sort of a clicking noise when its running. Gauge is fluctuating between 1500-1900. Fluid level is good. Everything is running fine. But have never heard this before. Nothing is lose.

Any thoughts

Check the coupling between the motor and the pump. It could be slipping.

Thanks. It was a little loose.
