1. A grease fitting replacement tool, the grease fitting replacement tool comprising:
a housing having a housing longitudinal axis, a housing anchor end, a housing drive end, a top, and a bottom; a shaft, the shaft at least partially enclosed within and extending from the housing drive end, wherein the shaft comprises a shaft body, a shaft first end, and a shaft second end, wherein the shaft is configured to move along the housing longitudinal axis; an adaptive socket, the adaptive socket comprising a cupped end and a shaft end, wherein the shaft end is removably mounted on the shaft first end, wherein the cupped end is configured to grip a grease fitting; a loosening device, the loosening device removably coupled to the housing drive end, wherein the loosening device comprises:
a packed coupling, the packed coupling connected to the housing drive end, the packed coupling configured to create a seal around the shaft body;a stem housing, the stem housing attached to the packed coupling, wherein the stem housing is configured to guide a stem, the stem housing having a longitudinal axis; anda stem drive system, the stem drive system mounted to the stem housing, the stem drive system comprising:
the stem, the stem connected to the shaft second end and at least partially enclosed within and extending from the stem drive system, wherein the stem is configured to move the shaft along the longitudinal axis of the stem housing;a threaded mount, the threaded mount connected to the stem housing, wherein the threaded mount is configured to pass the stem along the longitudinal axis of the stem housing; andan actuator, the actuator connected to the threaded mount, wherein the actuator is configured to drive the stem along the longitudinal axis of the stem housing; a main valve positioned in the housing through which the shaft passes, the main valve configured to achieve a closed position,
wherein the closed position seals the housing anchor end from the housing drive end; a fall-out trap positioned in the housing between the main valve and the housing anchor end, the fall-out trap configured to hold the grease fitting clear of the housing longitudinal axis; a pressure port valve positioned in the housing, the pressure port valve configured to allow for pressurizing the housing anchor end to a predetermined housing pressure; a vent valve positioned in the housing between the main valve and the housing drive end, the vent valve is configured to relieve the pressure in the housing drive end when the main valve is in the closed position; a pressure gauge, the pressure gauge configured to display the predetermined housing pressure in the housing; and a temporary mounting system configured to temporarily secure the grease fitting replacement tool to a piece of equipment, such that the housing anchor end is flush with the piece of equipment. |
