    I have a Mec 9000H hyd cyl I would like to rebuild and or reseal.It has the
    screw off end caps so it should be rebuildable. Mec parts don't show any
    o-rings or seals for the cylinder. Can anyone supply any info or diagram
    of the cyl? Cyl is weeping oil around the ram on the top Thanks for any
    and all info.. Larry from Indiana.

    I saw a posting quite some time ago that said these are the parts you will need:

    MEC Hydraulic Cylinder rebuild

    QTY -- Part Number -- Description
    2 ----- 2020 ---- O-Ring
    1 ----- 8860 ---- Seal 1" Polypack (Piston)
    1 ----- 8858 ---- Seal 1/2 Polypak
    1 ----- 8765 ---- O-Ring

    I called Mec this morning and have parts on the way.. O-Ring 8765 above is
    not required to be replaced. Also sending me a parts breakdown of the cylinder.
    Also need to replace the 2 internal springs #'s 8736 and 8737 (less than $6.00 bucks). If there is any interest, I may be able to post here when it
    arrives.
    Thanks for the response. Happy Shooting Larry
