According to one embodiment, a grease filling method for a ball screw device includes the steps of covering an outer periphery of a screw shaft protruding from one end portion of a nut with a covering member, supplying grease to a portion between a nut inner peripheral surface on one end portion side of the nut and the screw shaft, inserting the protruding screw shaft into a nut inner side while being covered with the covering member by relatively rotating the screw shaft and the nut, bringing a tip of the covering member in an insertion direction closer to an end portion of an infinite circulation path on the one end portion side of the nut, and sending the grease supplied to the nut inner side to a region of the infinite circulation path, pulling out the covering member together with the screw shaft from the one end portion of the nut by relatively rotating the screw shaft and the nut in an opposite direction, and taking out the covering member from the screw shaft.

A transmission for a motor vehicle includes a housing and a gear set. An oil drainage channel is formed by the housing and/or by an element connected to the housing and is arranged spatially underneath the gear set. The oil drainage channel includes at least one gear set-side inlet port, a closed underside, and an oil sump-side outlet port at one end of the oil drainage channel, which are designed and arranged in such that oil from the gear set enters the oil drainage channel through the at least one inlet port and is guided along the closed underside to the outlet port. A suction port of a hydraulic unit of the transmission is arranged in the oil sump spatially underneath the closed underside of the oil drainage channel and axially offset with respect to the outlet port.

A machine for replacing used transmission or power steering fluid in a vehicle with new transmission or power steering fluid includes a frame having a housing. The machine includes a pair of service hoses that extend from the machine and connect to the vehicle for placing the machine in the fluid flow. New, used, and axillary fluid tanks are provided. A pump and a manifold are associated with two of the tanks. The pumps provide for the selective withdraw or insertion of fluid into or out of the tanks. A display on the housing presents an operator of the machine with various tasks or options the machine can perform. A processor controls activation of the pumps and other electrical components based on inputs received by the display. Scales are provided under one or more of the tanks for determining the amount of fluid going into and out of the tanks during the exchange process.

A transmission housing (101, 111) has at least one bead (115) for forming one or more housing feed-through passages (117). A method of producing the transmission housing and a transmission series are also disclosed.

A service tool is designed for releasable coupling to a service port receiver connected to a service port associated with a gearbox. The service tool includes a coupling arrangement for releasably coupling to the service port receiver. The coupling arrangement is configured for rotational movement about the said receiver between a released position and an engaged position. A locking actuator is operatively coupled to the coupling arrangement and arranged for axial movement between a locked position and an unlocked position relative to the service port receiver. A plunger actuator is adapted for connection to the fluid conduit, which plunger actuator is slidably coupled to the coupling arrangement for movement between open and closed positions. In the open position, with the coupling arrangement in the engaged position and the locking actuator in the locked position, the plunger actuator is adapted to contact a check valve of the service port receiver and open it to permit fluid flow between the gearbox and the fluid conduit via a fluid pathway formed at least in part by the plunger actuator.

A filling and draining device for filling lubricant into and draining lubricant out of a housing (1), having a lubricant line (2, 21, 22) through which the lubricant passes into the housing (1), during filling, and through which the lubricant passes when the lubricant is drained from the housing (1). The housing (1) has a valve (6) through which the lubricant flows during filling and draining such that, for filling, the valve (6) adopts a first aperture width for the lubricant and, for draining, the valve (6) adopts a second aperture width for the lubricant.

An oil change system. The oil change system includes a plurality of fluid systems and a control circuit. Each of the fluid systems is couplable to a quick fit valve of a vehicle. The control circuit is coupled to the plurality of fluid systems, comprises a processing circuit, and is configured to control delivery of a predetermined volume of a fluid to the quick fit valve of the vehicle.

A system includes an oil filling device for a transmission, the transmission having a recess. The oil filling device includes a slotted bushing which is provided with an axially uninterrupted recess through which a cone unit projects, the cone unit having an external thread onto which a nut is screwed, on the side of the slotted bushing facing away from the transmission. The cone unit includes a region that widens in the direction of the transmission, and/or a cone region which presses the slotted bushing against the transmission, in particular in the axial region covered by the recess.

A port insert for a marine lower unit includes a hollow body having a first end and a second end, the second end having a first exterior thread configured to couple with a cap and one or more apertures formed in the body adjacent the first end. The port insert also includes a spring mechanism disposed within the hollow body. The port insert further includes a sealing member coupled to the spring mechanism, the sealing member being biased toward the second end in a non-use state.

An oil change system. The oil change system includes an evacuation system, a refill system, one or more sensors and a control circuit. The evacuation system includes a first quick connect fitting configured to mate with a quick connect valve of a vehicle. The refill system includes a second quick connect fitting configured to mate with the quick connect valve of the vehicle. The control circuit is coupled to the evacuation system, the refill system and the one or more sensors, and is configured to automatically identify the vehicle, determine a type, a viscosity and a volume of oil associated with the vehicle and control a volume of new oil added to the vehicle.
