A fluid deflection shield assembly for use with an oil well pump having a polished rod reciprocating within a stuffing box and providing a fluid-tight seal entirely around the stuffing box and the polished rod whereby the fluid deflection shield assembly may be attached or removed without interrupting the operation of the oil well. The fluid deflection shield assembly includes a bottom pan having a hole to receive the stuffing box, a gasket between the bottom pan and the stuffing box, a conical shell adapted to surround the stuffing box, a seal in the top of the conical shell between the conical shell and the reciprocating polished rod, clamps connecting the base of the conical shell and the bottom pan, and lubricating means in the conical shell to lubricate the polished rod. The bottom pan has an arcuate front section and an arcuate rear section, with the arcuate front section having a semi-circular hole which mates with a semi-circular hole provided on the arcuate rear section to form the hole to receive the stuffing box. Clamps are provided to connect the arcuate front and arcuate rear sections of the bottom pan. At least one drainage hole is provided in the bottom pan for removing liquid. The conical shell has an arcuate front section and an arcuate rear section, the arcuate front section having a semi-circular hole which mates with a semi-circular hole on the arcuate rear section to form a hole to receive the reciprocating polished rod. Clamps connect the arcuate front and arcuate rear sections of the conical shell.
