[/x_tab][x_tab active=”false”]

  1. Depress the trigger to reveal the 4 jaws.
    Use vic grip pliers to grip the tip and turn anti-clockwise to loosen tip.
  2. Remove the tip and 4 steel jaws from the coupler.
    Assemble the 4 new jaws around the new tip.
    Ensure the 4 new jaws are spaced evenly around the new tip.
  3. Holding the 4 new jaws tightly around the new tip with your fingers, insert the new tip into the end of the coupler body and tighten with pliers.
  4. The short end of each of the 4 new jaws should fit into the retaining groove just above the thread on the new tip.

Replacement kit instructions

Step 1. Squeeze the lever to determine where to attached the vice or vice-grip pliers

When squeezing the lever, see the portion of the flat steel exposed at the base of the coupler. This is where you will attach your vice or vice-grip pliers.

[/x_slide][x_slide]


Step 2. Attach the vice or vice-grip pliers to the G-Products Grease Coupler

The vice, or pliers, will only have a small piece of the coupler to attach to, so don’t be afraid to crank down on them and get a tight grip. When depressing the lever, you can see that the steel jaws of the seal kit are exposed and ready to be replaced.

[/x_slide][x_slide]


Step 3a. Remove old seal kit

Using a pair of vise-grip pliers, get a very firm grip on the steel jaws of the seal kit. Because the jaws will be greasy and may rotate, you’ll need to really squeeze them. Don’t worry about damaging the jaws or the interior cone with your pliers, as these will all be replaced in a moment. Once you have loosened the interior cone by rotating the pliers counterclockwise, you can remove the pliers and continue to twist with your fingers.

[/x_slide][x_slide]


Step 3b. Remove old seal kit

After loosening the inner cone you can remove the seal kit by hand by continuing to pinch and twist the steel jaws until they can be removed.

[/x_slide][x_slide]


Step 4. Assemble the new seal kit

The steel jaws have one edge larger than the other, this is the edge that should go at the top (large end) of the cone. Placing a small amount of grease on the inner cone first can help to ensure that the jaws stick and don’t fall out before being placed in the G-Coupler Grease Coupler.

[/x_slide][x_slide]


Step 5. Insert the new seal kit

Holding the four steel jaws in place, put the new seal kit into the G.Coupler Grease Coupler. Once inserted it can be twisted by hand until the jaws start to slip on the inner cone.

[/x_slide][x_slide]


Step 6. Tighten the new seal kit using vice-grip pliers

You should loosen your pliers before gripping the new seal kit. Unlike the removal process, you should be able to tighten the new seal kit without applying too much pressure. Once the inner cone feels snug, you are ready to use your G-Coupler again.

Just wanted to let you know your grease Zerk is the cats meow. I’am a logger that works by himself so that clamping on the zerk saves me a ton of grease and cuts time just knowing the machine got the grease and not end up in the belly pan.
Thanks again money well spent !
