  • Don't have a clue from just that description. Take a hose off and see if you are getting flow to the cylinder(s) when you operate the control valve. Watch out - it can get messy....

  • What does "packed the cylinder" mean?

    WHat is the overall condition of the hoses? It's possible there is a flapper in the line to the cylinder, restricting flow. It may require a gauge to measure the pressure accurately.

    Did you install a rebuild kit spec'd for your cylinder?

    You may want to disassemble the cylinder and make sure you didn't cut an O ring on installation and make sure any other seals are installed correctly.

    Clevis isn't bent and binding? Same for the cylinder bore, no dents etc.? . Rod is straight and undamaged?

    I'm not sure of the configuration of the cylinder you are working on. Some have a single O ring to seal the piston in the bore, others more complicated sealing components, chevron seals, proprietary O rings or square profiled looking common but aren't.

    Based on the size and application I doubt your cylinder is very complicated.

  • FOrgot to ask: DId you bleed the system? I don't have any experience with the ford or aftermarket loaders hydraulic systems. Mine was with 220" five stage end dump and three axle dump truck cylinders along with an occasional CAT cylinder.

    There are slightly different procedures for the many varieties and size cylinders. You will have to go online to find the proper procedure for bleeding the type and model cylinders you have. In any event it's not difficult and only as messy as you let it be.
