I have a 310sl I believe it’s a 2016, the hydraulics are weak. I have to put it at 1800 rpm to make it run normally. Any suggestions?
Start with simple, has hydraulic filter been serviced lately?
And cut that filter open to inspect it for debris.
Just reread post, are hydraulics weak or just slow below 1800 rpms? Don't know much about 310sl but rated operating rpm for Case 580C is measured @2100 rpm. Just made me think.
I meant to say they are slow. We just replaced the hydraulic filter and fluid that was the first move. I didn’t think to cut the filter open I might still have it. Assuming the filter is clean, what would be my next move?
Machine serial number? Both loader and backhoe functions affected? Does it make a difference if the seat is facing front or the rear? Will the hydraulics move at idle, seat front or rear, loader or backhoe?

Standing at the rear of your machine and looking at your backhoe control valve, the section all the way to the right, there is a relief valve sticking out towards you. Remove it and look at it real good. Anything stuck in there? If not, then a pump flow test may be in order. Was there any metal in the filter?
They threw away the filter before I could cut it. The thrust washers were bad in the pump. Rebuilt and repaired. Thanks for the help!
