check valves?

[wheel]

check valves, how do they work and why:confused2:

 

[kennyd]

They work by blocking flow on one direction while allowing flow in the other.

Why?

about a four weeks ago i was pushing gravel in the drive and the pedal just fated away it"s like i broke a spring in a valve,i have the tractor tore down now i have pulled all the valves and check valves they all look good no springs broken just not getting full pressure

 

[kennyd]

Do you have the FSM (factory service manual)? Did you follow the procedures for checking pressures at the test ports? Or are you blindly ripping it apart "hoping" to find a part that yells out that it's broken?
