When removing the collar with pliers, how many degrees should you rotate the pliers after squeezing the collar?

When removing the collar with pliers, rotating the pliers 90 degrees after squeezing the collar is critical for effective disengagement. This 90-degree rotation allows for enough movement to loosen the collar from its position without causing damage to the surrounding components or the collar itself.

In practical terms, this method leverages the mechanical advantage provided by the pliers. By rotating the pliers, you create a better angle for the jaws to grip and pull the collar away from the attachment point. This technique is especially important in aerospace assembly where precision and care are paramount in handling components to maintain structural integrity and avoid misalignment.

Other rotation degrees such as 45, 180, or 360 degrees may not provide the needed leverage or could potentially lead to complications such as stripping or deforming the collar, resulting in further difficulty in removal or damage to connected parts. A 90-degree turn strikes a balance between effectiveness and safety in the removal process, making it the appropriate choice.
