Abstract
The universal joint puller includes three members, one of which is a tubular sleeve having a flange and housing therein a compression spring and an abutment plug. The flange is seated against a drive shaft or universal shaft yoke and a force is applied through a screw and a pair of cables to force a cross or spider in a direction to move an associated bearing assembly toward and against the abutment plug and the opposing force of the compression spring. The latter construction permits the universal joint puller to be utilized with vehicles below 26,000 lbs. vehicle gross weight which do not have threaded bearing assembly cover plate bores associated with the yokes.
Claims52
A universal joint puller for disassembling a universal joint including its cross and bearing assembly from a drive shaft yoke, universal shaft yoke or the like comprising first and second relatively movable members adapted to be moved between a first relatively adjacent position and a second relatively spaced position, means for applying a force between said first and second members to move the same from said first position to said second position incident to removing a bearing assembly from an arm of an associated universal joint cross, a pair of flexible cable means for entraining arms of the cross generally normal to the arm from which a bearing assembly is to be removed, each of said pair of flexible cable means having opposite ends connected to said first member whereby upon operation of said force applying means said movable members are moved from said first position toward said second position, means for bearing against an end face of a yoke and preventing movement thereof during relative movement of said first and second members toward said second position, said bearing means further defining access means for receiving therein a bearing assembly upon the removal thereof from its associated universal joint cross arm upon said relative movement of said first and second members toward said second position, and means for imposing a force against a bearing assembly in opposing relationship to the direction of removal of the bearing assembly from its universal cross arm.
A universal joint puller for disassembling a universal joint including its cross and bearing assemblies from a drive shaft yoke, universal shaft yoke or the like comprising first and second relatively movable members adapted to be moved between a first relatively adjacent position and a second relatively spaced position, means for applying a force between said first and second members to move the same from said first position to said second position incident to removing a bearing assembly from an arm of an associated universal joint cross, a pair of flexible cable means for entraining arms of the cross generally normal to the arm from which a bearing assembly is to be removed, each of said pair of flexible cable means having opposite ends connected to said first member whereby upon operation of said force applying means said movable members are moved from said first position toward said second position, means movably carried by said first member for bearing against an end face of a yoke and preventing movement thereof during relative movement of said first and second members toward said second position, and means for imposing a force against a bearing assembly in opposing relationship to the direction of removal of the bearing assembly from its universal joint cross arm.
A universal joint puller for disassembling a universal joint including its cross and bearing assembly from a drive shaft yoke, universal shaft yoke or the like comprising first and second relatively movable members adapted to be moved between a first relatively adjacent position and a second relatively spaced position, means for applying a force between said first and second members to move the same from said first position to said second position incident to removing a bearing assembly from an opening in an arm of an associated universal joint cross, a pair of flexible cable means for entraining arms of the cross generally normal to the arm from which a bearing assembly is to be removed, each of said pair of flexible cable means having opposite ends connected to said first member whereby upon operation of said force applying means said movable members are moved from said first position toward said second position, means for bearing against an end face of a yoke and preventing movement thereof during relative movement of said first and second members toward said second position, said bearing means further defining access means for receiving therein a bearing assembly upon the removal thereof from its associated universal joint cross arm opening upon said relative movement of said first and second members toward said second position, and means for accurately axially locating said bearing means relative to the axis of an opening of a yoke arm from which a bearing assembly is to be removed.
