GR pulling tool is composed of GU shear up adaptor (upward shear adaptor) and GS pulling
tool (without shear pin), which can be released by upward shear. It is usually used for fishing
lock mandrel, packers ,and bridge plugs with internal fish necks.

III. Structural characteristics:
GR pulling tool is mainly composed of GS pulling tool (1) and GU Shear Up Adaptor (2), as
shown in the attached assembly drawing.
During fishing operation (refer to GS assembly drawing), when the fishing claw (8) touches the
mouth end of the inner fishing neck, it will retreat and fall into the slightly smaller diameter of
the core (9) and be retracted; When the fishing claw (8) completely enters the inner fish neck,
the fishing claw (8) is immediately opened to catch it under the thrust of the compression
auxiliary spring (5). If the tool is blocked upwards, it can be shaken off.
1. Install shear pin:
1.1 first install the shear pin of GS pulling tool (see the specification of GS pulling tool for specific
1.2 then tighten the coupling nut (4) on GU Shear Up Adaptor on the fish neck of GS pulling tool (5);
1.3 install the fishing neck (1) of GS pulling tool on the coupling nut (2) of GU Shear Up Adaptor
and align it with the pin hole;
1.4 refer to the assembly drawing of GU Shear Up Adaptor, install the cylindrical pin (3) and shear
pin (6), screw the hexagon socket set screws with flat point (5), and rotate the sheath (2) to protect
the shear pin (6);
1.5 refer to the assembly drawing of GS pulling tool, and screw off the outer cylinder (7) of GS pulling
tool to expose the shear pin;
1.6 punch out the shear pin with a punch;
1.7 retighten the outer cylinder (7).
2. Fishing operation:
2.1 connect GR pulling tool under the basic tool string;
2.2 Run the tool string, and determine whether it reaches the salvaged tool through the weight indicator
of the ground winch;
2.3 If the fishing tool is buried by sand, it can be shaken down;
2.4 After slight upward shock, lift the tool string;
2.5 If the lifting is blocked as above, the shear pin can be shaken up and cut off.
3. Unblocking on the ground (refer to the assembly drawing of GS pulling tool):
3.1 Push down the tool and stand against the end of the inner fish neck;
3.2 Squeeze the claw fixing seat (6) from the outer cylinder (7) of the GS pulling tool and pull it up to
1. When running the GR pulling tool, check whether the fishing claw is open and retracted normally;
2. Check whether the threaded connection of GR pulling tool is loose;
3. When using GR pulling tool, it is not allowed to install shear pins on GR pulling tool, so as to avoid
being unable to get rid of it.
V. Disassembly and assembly:
1.1 install shear pin on GS pulling tool first;
1.2 punch out the shear pin (6) on GU Shear Up Adaptor with a punch;
1.3 Screw off the hexagon socket set screws with flat point (5) on the coupling nut (4) with an Allen wrench;
1.4 flush the cylindrical pin (3) and remove the upper joint (1);
1.5 the vice clamps the coupling nut (4), the pipe wrench clamps the fish neck of the GS pulling tool (5), and
the coupling nut (4) is removed;
1.6 remove the GS fishing device GS pulling tool (see the operating instructions of GS pulling tool for steps).
1. It is strictly forbidden to use pipe tongs to clamp on the diameter of the fish neck for disassembly, so as not
to damage this surface and affect fishing;
2. It is forbidden to use pipe tongs to clamp on the upper thread of skirt sleeve to avoid deformation.
2.1 firstly, install the GS pulling tool (see the operating instructions of GS pulling tool for specific steps);
2.2 complete the assembly of GR pulling tool according to the steps of installing shear pin.
1. When assembling, the threads must be coated with grease;
2. External burrs or scratches of all parts shall be leveled with a file.
VI.Maintenance 1. After the tool is disassembled, check the damage of each component and replace the
2. When assembling, apply a thin layer of grease on the thread surface.
3. After assembly, the fishing neck is attached with thread protector and marked for later use.
