530 case backhoe

[pinball]

i have a 530 case backhoe. it sounds like it has air in the system but ive filled the hydraulics up. it it doesnt seem to have alot of digging / lifting power. im thinking maybe the relif valve nees adjusting. theres a large nut on the backside of the control block. is that where the relief valve is. any suggestions and help is appreciated. if you live close to 65270 ill gladly pay to fix this thing. thanks for reading.

There is a relief valve on the back of the loader controls that is the main relief. I would pull it out and check to see if it's broken. Had one brake the whole end off once. It's getting tough to find parts for these.If it's not broke hook a pressure gauge up to check the pressure. Turning it in increases your pressure.
