    I have an old cable operated Western plow pump and the lift ram is leaking. I tried tightening the packing nut but it still seems to leak. How tight should the packing nut be? I'm using a pretty big pipe wrench and I don't want to over tighten them.

    Periodically verify the lift cylinder and
    angle cylinder packing nuts have not
    loosened. If a packing nut is loose or
    excessive leakage appears when
    activating the cylinder, tighten the
    packing nut 1/4 turn maximum after
    you feel the packing nut contact the
    Do not overtighten the packing
    nut. Over-tightening affects
    plow operation and the life of the
    NOTE: A small amount of leakage
    is necessary to properly lubricate
    the cylinder rod.
    The lift or angle cylinder packings
    may dry out if the plow is not used for
    a period of time. If the lift arm is
    difficult to push completely down
    when the control is in float, or the
    plow angles slowly and causes
    excessive load on the motor, loosen
    the lift or angle cylinder packing nuts,
    lubricate the cylinder rods with oil and
    cycle the plow using the control.
    When the packings are lubricated,
    tighten the packing nuts and recheck
