Why is my Greenlee 767 Water Pump leaking oil at the coupler, and the ram won't advance?

  An oil leak at the coupler with a non-advancing ram in your Greenlee Water Pump can stem from several issues: * A loose or damaged fitting, in which case you should tighten or replace the fitting and/or coupler. * A worn or damaged O-ring, which requires O-ring replacement. * Insufficiently tightened coupler, preventing check ball engagement; hand-tighten the coupler completely to engage the check balls.

  If your Greenlee Water Pump is leaking oil at the coupler while building pressure, it could be due to: * A worn or damaged V-packing seal, in which case you should replace the two V-packing seals. * A damaged cylinder wall, which requires replacing the reservoir tube. * A leaking ball in the release knob; check the seat for scratches or contamination and reseat the ball. If the problem persists, return the pump to an authorized Greenlee service center for repair.

  If there's an oil leak at the coupler of your Greenlee Tools, and the pump builds pressure but the ram doesn't advance or return, several issues could be at play. It might be that a fitting is loose or damaged, in which case you should tighten or replace it, including the coupler. The O-ring could be worn or damaged, requiring replacement. Ensure the coupler is sufficiently tightened by hand to engage the check balls. Other potential issues include a worn or damaged O-ring (18), a bent release stem (15), or worn O-ring (25) and backup ring (27), all of which would need replacing. Additionally, check for punctures or wear in the bladder plug (14) or rubber bladder (12), and replace if necessary. Also, inspect the O-ring (13) for damage or incorrect positioning, and replace or reposition it....
