Hydraulic ram will not extend.

[HarryB97]

We have a Mcconnel Pa60e Hy Reach hedge cutter and one of the rams will not extend but It will retract everytime without issue. The control box is fine and we have replaced the valve which controls it but still no luck. Could the ram of broken up inside? All the other rams work fine.

Undo pipe off faulty side of ram and rule out the valve chest/solenoid before going any further.

Delaminated pipe acting like a one way valve?

@Dave W
Swap the wires.
Swap the pipes.
Swap the operator?

Have you swapped the hoses to see if problem is still there or reversed?

 

[Dave W]

Could be gland come unscrewed from the rod. But then the rod would likely have popped out the end.
Swap the hoses over on the ram see if it retracts but not extends.
