Abstract: A hose clamp pliers for use with both a wire spring hose clamp and a band spring hose clamp is disclosed. Two arms of the hose clamp pliers each rotatably carry contact points of different configurations. The first contact point is designed to receive, in a first position, an end portion of a wire spring clamp through a notch; and in a second position, to receive a hoop-shaped end of a band spring clamp. The second contact point is configured to receive both an end portion of a wire spring clamp, and a tab-shaped end of a band spring clamp. The hose clamp pliers is provided with a thumb release cooperating with a ratcheting pawl to control opening and closing of the pliers arms, which opens and closes the hose clamp.

Abstract: A pliers switchable for use with external snap-rings and internal snap-rings. The pliers has a first member with V-shape track, a second member with an aperture, and a switch mechanism. The second member and the switch mechanism are translatable along the V-shape track, and the switch mechanism is configured to engage and disengage the first and second members in and out of a “locked” position.

Abstract: A pliers switchable for use with external snap-rings and internal snap-rings. The pliers has a first member with an aperture, a second member with an offset V-shape track, and a pin with two parallel straight sides and two opposing outwardly curved sides. The pin is received within the aperture and the offset V-shape track and is moveable within the offset V-shape track.

Abstract: Apparatus directed to the art of disengaging an input from an output at predetermined torque values. A torque limiting clutch capable of use as a solid drive unit and a torque limited unit for which the torque disengagement value is selectable. The torque limiting clutch has an overload assembly and a torque drive mechanism which may comprise a plurality of drive pins. Additionally, the torque limiting clutch may comprise seals to discourage contaminants from entering the clutch.

Abstract: The present invention relates to a one-way freewheel clutch type wrench, more specifically to an indicator mechanism for providing audible and/or tactile feedback when a one-way freewheel clutch wrench rotated in the unrestricted, or “reloading”, direction. The indicator mechanism has a ratchet wheel with teeth attached to a one-way freewheel clutch socket which. interacts with at least one indicator located in a pocket of the box-end of the wrench.

Abstract: A tool adapted to be used with a filter cap having an engagement structure includes a body having an upper end and a side wall extending from the upper end and terminating in a lower open end. The side wall is formed with a plurality of notches extending upwardly from the lower open end and adapted to receive the engagement structure of the filter cap. The notches define a set of spaced apart engaging members which form a driven head receiving structure adapted to matingly and non-rotatably receive the engagement structure of the filter cap. The body is engagably disposed over the engagement structure, and the body together with the filter cap is rotated in a clockwise or counterclockwise direction.

Abstract: A disc brake piston retractor tool is provided for retracting at least one piston of a caliper assembly. The tool includes first and second pressure plates having respective externally threaded first and second studs. A coupler is internally threaded to threadably receive the first stud and the second stud from opposite open ends of the coupler. Selective rotation of the coupler results in simultaneous lateral movement of the first and second pressure plates towards and away from the coupler between retracted and extended positions. One of the pressure plates is engageable against the at least one piston to retract the piston, and the other of the pressure plates is supported against an interior surface of the caliper assembly opposite the one piston, or is engagable against at least one other piston in the caliper assembly opposite the one piston to retract the other piston.

Abstract: An adjustable holding tool is provided for servicing a fan clutch assembly removably attached to a shaft of a water pump having a pulley associated therewith. A holding tool is comprised of a first plate holder including a first adjustment leg joined to a first attachment leg having a first longitudinal axis and a first attachment structure. A second plate holder includes a second adjustment leg joined to a second attachment leg having a second longitudinal axis and second attachment structure. The first and second plate holders are slidably connected together to provide a continuous variable spacing between the first and second adjustment legs while maintaining a parallel relationship between the first and second longitudinal axes.

Abstract: A pulling tool includes a elongated main support body having a plurality of retention holes formed on opposite sides thereof. An actuator stem member is threadably mounted in the support body. A pair of jaw members is slidably mounted on opposite side of the support body. The jaw members have extended hook portions adapted to engage an outer periphery of a wheel element removably mounted on a stationary wheel mounting member. A pair of tubular holders is slidably mounted on opposite sides of the support body, and retained against outer faces of the jaw members to prevent lateral outward movement of the jaw members on the support body and to orient the jaw members substantially perpendicularly to the support body.

Abstract: A compression tester adapter assembly is provided for use with both 12 millimeter and 16 millimeter spark plug sockets in an internal combustion engine cylinder head. An adapter has a leading cylindrical portion including one set of external threads configured with a nominal diameter of 12 millimeters, and a trailing cylindrical portion spaced from the leading cylindrical portion and including another set of external threads configured with a nominal diameter of 16 millimeters. The axial spacing between a first leading full thread on the 12 millimeter threads and a first leading full thread on the 16 millimeter threads lies in the critical range of 0.636?-0.737?. A hose has opposite ends attached to the adapter and a connector.

Abstract: A holding tool is adapted to be used in removing and replacing a fan clutch assembly threadably attached and detached relative to a shaft of a hub connected to a pulley on an internal combustion engine of a vehicle by a series of fasteners. The holding tool includes a flat holding plate in which a portion of the bottom edge is provided with arcuate edge adapted to surround a circumferential segment of the hub. The holding plate is formed with a plurality of spaced apart holes adapted to receive certain of the fasteners connecting the hub and pulley together so that the holding plate is attached to the hub. An elongated handle has a proximal end secured to the holding plate and a distal end adapted to rest upon a frame rail of the vehicle.

Abstract: A convertible retaining ring pliers has a pivot, first and second jaws and first and second handles rotatably secured about the pivot. A pair of transfer pins is slidably disposed for selective movement in the first and second jaws and the first and second handles for establishing alternative operating positions enabling the jaws to move inwardly as the handles move inwardly and allowing the jaws to move outwardly as the handles inwardly. A switching mechanism is mounted to the handles and pivot for providing simultaneous shifting of the transfer pins in the jaws of the handles. The switching mechanism includes first and second flexing spring plates which are mounted on opposite ends of the pivot and disposed on opposite external surfaces of the handles. Each of the spring plates includes a pair of boss pins engageable with opposite ends of the transfer pins.
