Gear puller having improved puller arms for stability in operation thereof

A gear puller assembly comprising:

• a yoke that defines a plurality of puller arm receiving interfaces and a plurality of interior passages extending radially into the yoke from each of the of puller arm receiving interfaces;
• a threaded jack shaft threadably received through the yoke and having a pressing surface on an end thereof;
• a plurality of puller arms, wherein each respective puller arm is configured for being selectively engageable with a respective puller arm interface of the yoke;
• wherein a detent assembly extends from an interior portion of the yoke through at least a portion of one of the plurality of interior passages into each of the puller arm receiving interfaces, each of the detent assemblies configured for engagement with respective puller arms to cause the puller arm to maintain a locked position defined at an angle between the respective puller arms and the yoke,
• wherein each respective puller arm defines a plurality of ridges that are configured to engage with a respective detent assembly to selectively maintain the respective puller arm in a desired angular position,
• wherein engagement of the detent assembly from a ridge of the plurality of ridges to an adjacent ridge during rotation of the puller arm imparts an audible signal indicative of rotation of the puller arm,
• wherein each respective puller arm defines a shoulder that extends outwardly, the shoulder configured for being received within a recess defined within the yoke to selectively engage the respective puller arm with a respective recess within the yoke,
• wherein the shoulder defines a first cross-dimension that is smaller than a second cross-dimension, wherein rotation of the puller arm such that the shoulder first cross-dimension is aligned with a slot defined in the yoke allows for selective dis-engagement of the puller arm with the yoke.
