ABSTRACT:
An improved tool for pulling off a rotor of a motor from a shaft or a fan from a shaft, which improved tool is provided with hooked arms that are releasably but securely held at one end in the housing, without the use of retaining clips, so that the arms do not fall off during use or become lost, and so that they do not interfere with the use of the tool when using the securing bolts for pulling off a rotor. The hooked arms of the invention are also hexagonal shaped, and securing bolts are provided with hexagonal-shaped recesses in their heads, so that the hooked arms may themselves be used for rotating the securing bolts when pulling off a rotor of a motor from a shaft. To ensure that the each hooked arm is releasably retained in a respective hole of the housing, the end of the arm is provided with a hook defined by a straight piece extending at an acute angle with respect with the main, elongated body of the arm.
