1. An axle removal tool, comprising:
a first plate disposed in facing relation to a second plate, wherein the first plate has a C- or U- or V-shape defining a first leg and a second leg and a gap therebetween and the second plate has a C- or U- or V-shape defining a first leg and a second leg and a gap therebetween in substantially matching registration with the first plate;
a bellows arranged between the first plate and the second plate, wherein the bellows has a C- or U- or V-shape defining a first leg and a second leg and a gap therebetween in substantially matching registration with the first plate, said bellows having a compressed state when uninflated so that the first plate and the second plate are separated by a first distance, and having an expanded state when inflated so that the first plate and the second plate are separated by a second distance that is greater than the first distance, said bellows configured to receive compressed air via an intake opening therein to inflate the bellows to the expanded state, wherein said second plate defines an opening therethrough that is in fluid communication with the intake opening of the bellows;
a connector to fluidly connect the opening in the second plate to a source of compressed air; and
a clip spring operatively connected to the first plate and the second plate and configured to apply a spring force to continually urge the first plate and second plate toward one another so as to bias the bellows against inflation both when the bellows is in the compressed state and when the bellows is in the expanded state;
wherein as the bellows inflates with air from the source of compressed air, the first plate is pushed away from the second plate to overcome the spring force of the clip spring so that the first plate is spaced from the second plate by the second distance.
