    I'm replacing the seals in my hydraulic for my EZ-dumper. How do I get this unit apart?

    Spanner Wrenches

    About Spanner Wrenches
    There are two styles of spanner wrenches, pin style and hook style. Both styles are offered in fixed and adjustable versions.
    Fixed wrenches fit a single circle diameter. Adjustable wrenches fit a range of circle diameters—a good choice when you are unsure of the exact diameter you're working with.
    Pin style spanner wrenches fit into round holes. Holes can be located on the side (circumference) of rings, locknuts, and collars or on the face of flanges and collars.

    Holes on the Side

    Holes on the Face
    Hook style spanner wrenches fit into slots. Slots are located on the side (circumference) of rings, locknuts, and collars.

    Adjust collars, locknuts, rings, packing glands, adjustable rollers, power transmission bearings, as well as material handling and machine tool equipment. All are forged steel with a black finish, except Style F , which also come in Type 304 stainless steel. Type 304 stainless steel wrenches are corrosion resistant and can be autoclaved up to 600° F.

    I would take it to a hydraulic shop and let them put in the new seals. They can install the new seals and test the cylinder. I had one rebuilt for my tractor, and it only cost $35.00. My time is worth more than that. Thats just my opinion.

    well you just might want to investigate just how much somebody would want to put the seal kit in because it it true what basher says you can spend a fair amount to get tooled up to do it .i know the hardest part is holding the cylinder to get a firm grip on the wrench to loosen the gland nut .it's prob aluminum and you can screw it up easy.we used to have a steel bench to clamp the cylinder to .it kept it from turning buy use of a clamp strap or hyd clamp .ussmileyflag
