Abstract: A gear puller assembly includes a yoke that defines a plurality of puller arm receiving interfaces, a threaded jack shaft threadably received through the yoke and having a pressing surface on an end thereof, and 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. A detent assembly extends from the yoke through 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.
