Abstract: A plunger installation tool that exerts a force on a plunger for a reciprocating pump to install the plunger into a pump cylinder opening. Maintenance of the pump typically includes repacking of the packing that surrounds the plunger and revalving of the pump's inlet and outlet valve. To allow repacking or revalving, the pump is disassembled and the plunger is removed. The plunger installation tool threads onto the pump cylinder opening to provide a reaction point for a threaded rod that is driven at one end by a driver and engages the plunger at an opposite end during installation to push the plunger into the cylinder opening without the use of hammers by personnel.
