Various examples of a tool for lubricating a boat steering cable are described, along with examples of using the tool. In one example, a tool for lubricating a boat steering cable includes a lubricator barrel and a threaded lubricator pin. The lubricator barrel includes an outer cylindrical surface, a first end surface, and a second end surface. The lubricator barrel also includes a central barrel cavity extending from the first end surface, along a longitudinal centerline of the lubricator barrel, and a pin cavity extending from the outer cylindrical surface to the central barrel cavity. In some cases, the lubricator barrel also includes a first o-ring seat, a second o-ring seat, or both. The first o-ring seat is positioned at one end of the central barrel cavity and the second o-ring seat is positioned at the outer cylindrical surface of the pin cavity.

The device and method are for one shot greasing of tractor trailer fifth wheels and other structures. The device has an upper tube and a lower tube where the upper tube acts as a piston to push down on the lower tube to dispense a grease supply. The lower tube bottom, or a bottom cap connected thereto, has a plurality of dispensing orifices. Preferred embodiments include a stop mechanism to prevent relative movement of the upper tube and lower tube prior to dispensing, and a removable seal on the bottom that prevents grease release until the seal is removed.

A fitting for a lubrication point of a device to be lubricated and a connector for removably connecting to such fitting to provide a lubricant from a lubrication device via the fitting to the device to be lubricated are disclosed. The fitting comprises an integrated circuit for providing an identification code to identify the fitting, and a first electrical contact for establishing an electrical path between the integrated circuit and a processor of the connector when a connection between the fitting and the connector is established. The connector comprises the processor and a second electrical contact for establishing the electrical path. The integrated circuit is adapted for transmitting data, including the identification code, via the first electrical contact to the processor.

The present invention provides a quick-injection grease filling device, which features including an oil cup, a detachable guide seat, a screw, a piston, an oppression part and a rotating drive part. The piston is held inside the oil tank, capable of moving upward and downward. The piston has an oppression surface and a bearing placement surface. The detachable guide seat includes a combination part and a screw hole, and the combination part is attached to the cup mouth through a detachable assembly unit. The inner end of the screw extends into the oil cup, and the outward extending end extends out of the cup mouth. The rotation driving part is arranged on the outward extending end. The oppression part can move forward and backward along with the screw. The oppression part is used to press against the bearing.

The present invention relates to a grease application device in which a tip-side inclined surface of a nozzle 28 is made to closely face worm wheel teeth 11 of a shaft-mounted worm wheel 9 while rotating the shaft-mounted worm wheel 9 by means of a drive unit 12. At this state, the grease application device is configured to apply liquid grease from a tip-side opening of the nozzle 28 to the worm wheel teeth 11 of the shaft-mounted worm wheel 9 and to apply the grease while pushing the grease into concave portions of the worm wheel teeth 11. Also, the grease application device is configured to end the application of the grease at a point of time at which the shaft-mounted worm wheel has rotated one revolution with respect to the nozzle 28 after starting the application of the grease to the shaft-mounted worm wheel 9.

A holding member configured to hold an injection portion and an imaging unit of an insertion portion in a state in which the injection portion and the imaging unit are arranged side by side includes an injection-portion insertion portion configured such that the injection portion is press-fitted into the injection-portion insertion portion and an imaging-unit insertion portion configured such that the imaging unit is press-fitted into the imaging-unit insertion portion. The insertion portion is configured to be inserted toward a corresponding portion in a narrow space while being gripped by an operator. The injection portion has a cylindrical shape and is provided with a fluid substance injection port at a tip end portion. The imaging unit has a cylindrical shape and is configured to capture an image including the tip end portion of the injection portion and its surrounding environment.

A greasing device that feeds grease to a portion requiring greasing that is housed inside a housing, and includes a jig and a greasing pipe fixed to the jig. The housing includes a though-hole that extends through the housing. The jig includes an insertion part that is inserted into the through-hole of the housing. A side surface of the insertion part bear a marking-off line at a position a predetermined distance away from a leading end side of the insertion part. A position of the marking-off line is a height position that the greasing pipe does not come into contact with inner components of the housing when the jig is inserted into the through-hole up to the position of the marking-off line.
