A vehicle drive system includes a first prime mover, a transmission, a power take-off (PTO), a lubrication system for the transmission and the PTO, and a control system. The transmission is powered by the first prime mover. The transmission is configured to rotate a drive shaft of the vehicle. The PTO is connected to the transmission at a first interface. The PTO includes the first interface and a second interface. The control system is configured to control fluid flow through the lubrication system for at least one mode where the input section of the PTO is stationary and the output section rotates.

The present disclosure relates to an arrangement for transferring fluid to a guide bar in a chain saw. A channel can extend from a chain saw body to the fastening arrangement of the guide bar. The channel can include a cavity through the entire channel, a first end of the cavity being connected to a feed channel provided in the chain saw body and a second end thereof to a counter channel provided in the fastening arrangement. The counter channel, in turn, is arranged to extend to the guide bar. The channel is thus arranged to guide fluid flowing in the feed channel provided in the chain saw body through the channel and further through the counter channel provided in the fastening arrangement to the guide bar.

A vehicle main electric motor includes: a ring-shaped filling chamber, which is formed in contact with a ball bearing and a roller bearing in a direction of a rotation shaft, for filling with a semi-solid lubricant, and which has a central axis concentric with the rotation shaft; and a discharge section connected to the filling chamber, for inflow of the semi-solid lubricant from the filling chamber. A display member, which has a specific gravity lower than a specific gravity of the semi-solid lubricant, is arranged, in an interior of the discharge section, at an initial position that is a position not reached by the semi-solid lubricant during an initial greasing. The discharge section has a retaining part for retaining, at a movement position that is a determined position within the discharge section, the display member moving in a greasing direction due to pressure of the semi-solid lubricant during a supplemental greasing. At least a portion of visible light from the exterior reaches at least a portion of the movement position.

An apparatus for transporting a turbine engine with a transportation fixture including a turbine engine jig having mounts for securing the turbine engine, a rotor with a drive shaft rotationally supported by a bearing, the method includes supplying a lubricant to the bearing and rotating the drive shaft while the turbine engine is in transport.

An automatic lubricator for lubricating an object is described, which comprises a housing with a coupling section configured to couple with a lubricant container containing a lubricant, wherein the lubricant container comprises a rotatable shaft with a piston to dispense the lubricant from an output of the lubricant container. The lubricator further comprises an electric motor configured to drive the rotatable shaft of the lubricant container during at least one lubrication action, such that at least a part of the lubricant is dispensable from the lubricant container during the at least one lubrication action, and a power supply configured to supply the electric motor with a supply current during the at least one lubrication action. The lubricator further comprises a control circuitry configured to acquire a current signal indicative of the supply current over time during at least a part of the at least one lubrication action, determine a periodicity of the acquired current signal, and determine, based on the determined periodicity, at least one lubrication parameter indicative of the at least one lubrication action.
