Usage:
Four new gear and bearing pullers are available. These pullers with their attachments can be used for a variety of pulling applications, such as bearings, bearing cages, and gears.
The unique feature of these pullers is the positive retention of the puller jaws. The jaws are clamped to positively hold the puller in place. See Illustrations 1 and 2. Turning the T-handle moves the puller cage against the jaws and secures them to the part being pulled. The jaws can be secured to a round surface or in a small groove. The jaws are retained in position until the pulling process is complete, and the puller is released.

The pullers are available in four sizes, each determined by the pulling capacity in tons. See Chart A. Protector points are available to prevent damage to the forcing screw points when extreme force is applied. Extender points are also available for installation on the 9 and 18 ton (10 and 20 U.S. ton) pullers to give 38.1 mm (1.50") more reach.
Chart A lists the significant specifications of the pullers. Chart B shows the replacement parts that are available from Caterpillar, including the attachment protector points and extender points. See Illustration 2 for the location of the various parts.
