Separating is a variation of external pulling in which the part to be removed lies flush. In this situation, gripping with a standard external puller is not possible.

Separating is a variation of external pulling in which the part to be removed lies flush. In this situation, gripping with a standard external puller is not possible.

Normally, a separator blade is used in combination with a pulling device

It is also possible to extend the pulling devices for jobs involving longer shafts

In some cases, an appropriate puller from the 20 series can be used instead of the pulling device

Notes on separating

The extensive KUKKO line also supplies separator pullers with side clamps, such as the 210 Cobra series.

The adjusting nuts on the separator must be tightened in alternating and equal turns. Otherwise, the separator blade may tilt on the spindle or the spindle thread may be damaged.

When tightening the separator blade, ensure that before the pulling device is pulled upwards the blade is firmly seated up to the stop under the part to be removed.

Safety information

Carry out regular checks of the condition of the tool and replace damaged or worn parts.
Always keep the pressure screw and cross-beam threads clean and well-oiled.
Before use, make sure you know how to properly operate the pulling tool, in compliance with the necessary safety precautions.
If you are even slightly uncertain about one of the points mentioned above, you should request clarification on tool operation.
Make sure the pulling tool is in perfect condition before use.
Verify that the tool is attached correctly and monitor the force used during the removal process.
Never exceed the stated load values for the tool, and check the application of the pulling force by using a torque wrench for mechanical pulling tools and a pressure gauge for pump-operated hydraulic pulling tools.
Wear suitable personal protective clothing. Always wear protective goggles.
Protect yourself with a protective blanket against jerky movements that are always possible with pulling tools and the part being pulled when doing extraction jobs.
Should overload, stiffness, etc., occur, stop the removal process and use a larger version of the corresponding series to complete the job.
Do not use any electrical or pneumatic servo screwdrivers or impact screwdrivers to operate pulling tools.
Do not use extensions to increase the transmitted torque.
Do not make any modifications to the products.
Because the strength properties of steel change under the influence of heat, pulling tools may not be heated when the parts to be pulled are heated.
