The invention discloses a bushing disassembling and assembling tool. The bushing disassembling and assembling tool comprises a screw rod, wherein a first disassembling and assembling liner and a second disassembling and assembling liner which are located on two sides of a workpiece are arranged on the screw rod in a sleeving manner; the first disassembling and assembling liner is used for being abutted to a bushing; the second disassembling and assembling liner is used for being abutted to the workpiece; a first handle which is in threaded cooperation with the screw rod and is used for drivingthe first disassembling and assembling liner to move in an axial direction is arranged on the screw rod, and is located on one side opposite to the second disassembling and assembling liner, of the first disassembling and assembling liner; a second handle which is in threaded cooperation with the screw rod and is used for limiting the second disassembling and assembling liner is arranged on the screw rod, and is located on one side opposite to the first disassembling and assembling liner, of the second disassembling and assembling liner; the rotating direction of the screw rod is the same asthat of cooperating threads between the first handle and the second handle; and a kinetic friction coefficient between the first handle and the first disassembling and assembling liner is smaller thana static friction coefficient between the bushing and the first disassembling and assembling liner.
