An RCP pusher tool for use in maintenance of RCP motors wherein the tool utilizes a clamp assembly that fits over the existing bolts and nuts of the motor's lower bearing oil pan flanges, obviating the need for disassembly of the motor. The pusher tool is formed of two plates, each plate having holes disposed to fit externally over the bolt heads of the oil pan flanges. Disposed between the plates is a spacer block that maintains the plates in a spaced apart, parallel relationship. The spacer block also functions to support the pusher block itself. The spacer block has a threaded bore disposed for receipt of a pusher block positioning shaft. The threaded shaft has a motor shaft pusher block mounted to its distal end and is disposed to position the concave surface of the pusher block against the motor shaft. The two plates, when mounted over the bolts of the oil pan flange, are attached to one another by fasteners that can be adjusted with wing nuts to tighten the plates together over the bolt flanges. The pusher block can be adjusted into place against the motor shaft by means of the threaded positioning bolt. By avoiding the need to remove the oil pan bolts, the pusher tool can be installed quickly and easily without the need for prolonged exposure by maintenance personnel to the hazardous environment of a nuclear reactor cooling pump.

A portable fume exhauster and dryer includes a motor fan mounted in a housing having a supporting structure adapted to rest on a horizontal surface, such as a floor, or on an uneven or slanted, often narrow surface, for example, a window sill. The housing of the exhauster and dryer has flanges at intake and exhaust openings to which grilles and/or conduits can be attached for remote intake or exhaust of fumes and moisture. Circuitry for the device may be provided to prevent electrical shock, power surges and thermal overload, and a switch may be proved for operation by an operator wearing protective clothing, such as heavy gloves.
