ESB Pulling

The Model “ESB” Pulling Tool is designed to engage and retrieve downhole with an external fishing neck. Downward jarring is utilized to release the tool to be pulled.

The tool is operated by locating the “ESB” over the external fishing neck of the tool to be pulled. The pulling tool dogs latch onto the fishing neck. Cam surfaces on the dogs force the lower end of the dogs to be pressed inward, thereby ensuring a strong latch.

Should the pulling tool not be able to retrieve the downhole tool, it can be released from the fishing neck so it may be brought out of the hole. The shear pin can be sheared with repeated severe jarring. Once sheared, the cylinder spring forces the core to move up. This releases the pulling tool dogs. Once the lips of the pulling tool dogs release, the “ESB” can be removed from the hole and the shear pin replaced.

Changing the Shear Pin 1. Grip the Cylinder in a and remove the sub shear pin retainer. Remove the shear pin with a and . 2. Compress the pulling tool until the entire shear pin hole is properly aligned and visible. 3. Insert a new shear pin. 4. Replace both the shear pin retainer and the Sub.

Disassembly 1. Grip the cylinder of the pulling tool in a vise. 2. Remove the Sub and the shear pin retainer. 3. Rotate the Core so that the lower holes in it align with the holes in the cylinder. Insert a punch or some other similar tool to prevent the Core from turning. Remove the Nut. 4. Remove the punch. 5. Remove the cylinder spring. 6. Remove the core. 7. Remove the dogs. 8. Remove the washer. 9. Remove the dog spring. Assembly The assembly of the “ESB” is done in reverse except for two aspects. Before the cylinder spring is replaced, align the lower hole of the core with that of the cylinder and insert a punch. After the nut has been replaced, remove the punch and push the nut down until the upper shear pin hole on the core is aligned with the hole in the cylinder.
