Abstract: A device which may be utilized as a circuit testing device or a power source conductor device includes a handle with a single lead wire electrically connected to a light in series circuit with a probe. Further included is a push button switch on the side of the handle which may be manually moved to disengage the light from the circuit and simultaneously enable a series circuit directly to the probe to thereby provide a power source.

Abstract: A stud installation tool includes a thrust bearing mounted within an annular housing so that the bearing may be brought in contact with a wheel hub plate and fitted around a stud which is to be drawn into the plate. Lug nuts for the stud may be tightened against the tool thereby eliminating the necessity for special sizes and styles of stud nuts.

Abstract: A tool useful for engaging and pivoting the rocker arm of an internal combustion engine in order to enable removal of a push rod from the engine by virtue of positioning the rocker arm in a manner that disengages the rocker arm from the push rod includes a pair of bifurcated arms which fit on opposite sides of the rocker arm and further includes cross members connecting the bifurcated arms which engage the rocker arm in a manner that facilitates manual rotation of the tool and the rocker arm.

Abstract: A tool for spreading dual piston brake pads and for compressing the dual pistons of a dual piston disc brake assembly of the type including a disc brake caliper housing for the pads and pistons. The tool includes manually operated handles which drive a bracket assembly that engages the dual piston disc brake pads. The housing for the tool includes a plate which is engaged against the caliper housing. The plate and bracket assembly are driven in a manner which causes them to become spaced from one another. A mechanical advantage is achieved by utilization of handles with a lever arm extension associated with a pivotal handle.

Abstract: A tool for pulling or removing seals includes an elongate handle having a manual engagement end and a seal hook member attachment end with a seal hook member pivotally attached to the seal hook member attachment end. The seal hook member includes at least one hook element and a mechanism for pivotally adjusting and fixing the pivotal relationship of the seal hook member with the elongate handle member.

Abstract: A gasket removal and cleaning tool includes a drive rod rotatably retained within a sleeve enabling the rod to be driven by a die grinder. The opposite end of the drive rod projects from the sleeve and includes an abrasive element that may be used to remove a seal from a sealing surface and to polish or clean the surface.

Abstract: A grease fitting coupler device includes a body member with a slot on one side for engagement with a fitting and a series of passages through the body member connected with a lubrication source. A slidable valve member within the body member is pressurized against the fitting to seal the coupler device while lubricating fluid is passed therethrough.

Abstract: A trim panel removal tool is comprised of a thin metal blade having slots in one end and a lever arm at the opposite end. The slots of the blade may be inserted under the head of a fastener for attaching a trim panel or trim piece to a substrate panel, and the tool may then be twisted to cause disengagement of the trim panel fastener from the substrate panel.

Abstract: A tool for spreading brake pads and for compressing the piston of a disc brake assembly of the type including a disc brake caliper housing for the pads and piston. The tool includes manually operated handles which drive a rod attached to a plunger that engages one of the disc brake pads. The housing for the tool includes a backing plate which is engaged against the caliper pad. The backing plate and plunger are driven in a manner which causes them to become spaced from one another. A mechanical advantage is achieved by utilization of handles with a lever arm extension associated with a pivotal handle.

Abstract: A tool for spreading brake pads and for compressing the piston of a disc brake assembly of the type including a disc brake caliper housing for the pads and piston. The tool includes manually operated handles which drive a rod attached to a plunger that engages one of the disc brake pads. The housing for the tool includes a backing plate which is engaged against the second pad. The backing plate and plunger are driven in a manner which causes them to become spaced from one another. A mechanical advantage is achieved by utilization of handles with a lever arm extension associated with a pivotal handle.

Abstract: Clamping pliers includes a first handle with a first jaw, a second handle, a separate second jaw all of which are pivotally connected to a pivot to affect pivoting about the same pivot point. A connecting link connects the second jaw with camways defined in the first and second handles. A pin extending from the link engages the camways and upon closure of the handles provides a clamping action.

Abstract: A support frame assembly for supporting an engine in a vehicle engine compartment including a telescoping support beam supported by foot members which are adjustable to accommodate the configuration of the fender lips of the engine compartment. Adjustment of the support foot members relative to the horizontal cross beam may be effected in two degrees of motion by virtue of the connection mechanism of the foot member to the support beam.

Abstract: A fastener removal tool includes a handle, a projecting axial rod with a wedge shaped end for engaging the flange of a fastener and a slidable fulcrum member positioned on the rod.
