A fluid management system for a drivetrain includes a first reservoir, a second reservoir, a main suction line, and a second suction line. The first reservoir is positioned in a lower portion of a transmission. The first reservoir has a preselected fluid level. The second reservoir is positioned in a lower portion of the transmission. The second reservoir is separated from the first reservoir by a barrier having an opening. The main suction line has an opening positioned in a lower portion the first reservoir below the preselected fluid level. The second suction line has an opening positioned in a lower portion of the second reservoir.

An electrical connector installation tool for electrical connectors that include a main body and a screw-on end cap. The electrical connector installation tool includes a separate end cap tool and main body tool. The end cap tool and the main body tool may be structured to be hand gripped and hand turned around the tool body. To accommodate different electrical connectors of different sizes or different types, the end cap tool may include a pair of end cap sockets positioned on opposite ends of a hollow interior within the end cap tool. The end cap sockets may be sized and shaped to receive and turn screw-on end caps of different sizes. For example, one end cap socket could be sized and shaped to accommodate MC4 electrical connectors while the other end cap socket could accommodate H4 electrical connectors with larger screw-on end caps.

Disclosed is a roof safety anchor capable of permanent and watertight attachment to a roof. Installation of the roof safety anchor does not require the removal of roof shingles. The roof safety anchor captures a D-ring and a roof fastener between a base and a lid. The roof fastener extends through the base and a gasket to secure the roof safety anchor to the roof.

One or more techniques and/or systems are disclosed for a transmission variator. The variator receives input power from at least two power sources and provides variable speed output power paths for the transmission. A variator clutch assembly transfers input power to a variator shaft, which drives a planetary gear assembly, including a sun drive gear, planetary gears, and one or more ring gears. The ring gear(s) provide output power to a high output and low output gear assembly. A double reverse tapered spline between the sun drive gear and sun gear to provide forward thrust on the sun gear. A lubrication pin in the planetary gears can provide pressurized lubrication to the planetary gear assembly. A ring gear retention key can be disposed in a spur gear of the high output gear assembly, and ride in a groove in the underside of the ring gear to provide for alignment.

A sealing system for multiple fluids includes a transmission housing having a first port and a first opening, an electronic component connected to the transmission housing forming a vent space between the electronic component and the transmission housing, and a seal positioned between the electronic component and the transmission housing. The electronic component includes a first conduit. The seal includes an outer loop maintaining a first fluid outside of the outer loop. The seal includes a first inner loop surrounding the first conduit and positioned inside of the outer loop. The first inner loop maintains a second fluid inside the first inner loop. The first port is in fluid communication with the first conduit. The first opening is positioned inside of the outer loop and outside of the first inner loop. The first opening is in fluid communication with the vent space.

A multi-mode CVT for a work vehicle powertrain has a continuously variable power source (CVP), an input arrangement with an input shaft receiving engine power, a variator arrangement with a variator shaft supporting a planetary set, a drop set arrangement with a drop set shaft, and an output arrangement with an output shaft supporting an output component. The input, variator, and drop set arrangements include clutch components with the clutch(es) of the drop set arrangement transmitting CVP power or combined CVP and engine power to the output arrangement to provide a selective gear reduction for transmission of an output power according to a plurality of transmission modes, including a CVP-only mode and a combined engine and CVP split-path mode.

A method for spin set bearing setting verification in a preload state on a shaft. An inertia wheel may be disposed on the shaft. The inertia wheel or the shaft is rotated. A first rotational speed is measured at a first time. The inertia wheel may decelerate over time to achieve a second rotational speed measured at a second time. The second speed is less than first speed. The change in time between the first time and the second time is measured. The bearing setting may be adjusted if the change in time is outside a predetermined time range. The bearing setting may remain unchanged if the change in time is within a predetermined time range.

One or more techniques and/or systems are disclosed for a clutch configuration and/or clutch operation. The clutch configuration includes an arrangement having a transmission input shaft having a conduit therethrough and a rotating clutch drum configured to rotatably couple to the transmission input shaft and operate independent of the transmission input shaft. The rotating clutch drum has a conduit complementary to the conduit of the transmission input shaft. The clutch arrangement further includes a bearing spacer between the transmission input shaft and the rotating clutch drum, wherein the bearing spacer has a conduit complementary to the conduit of the transmission input shaft and the conduit of the rotating clutch drum. The conduits of the bearing spacer, the transmission input shaft, and the rotating clutch drum define a clutch apply pressure path to control actuation of the rotating clutch drum.

A circular rear view eyewear mirror, approximately 9 min. in diameter, consisting of a reflective surface permanently attached with epoxy adhesive to a cylindrical plastic base with one end obliquely cross-sectioned to form an ellipse. The angle formed by this oblique cross-sectioning of the base allows the rear view eyewear mirror to fit differing types of eyewear, including modern wrap-around sports eyewear. The elliptical end is attached semi-permanently to the rearward surface of the eyewear lens with double-backed adhesive tape. These elements, when assembled, are considered one piece in use and have no moving parts in relation to each other. The rear view eyewear mirror may be angularly adjusted by clockwise or counter-clockwise rotation before semi-permanent attachment by rotation upon the rearward surface of the eyewear lens. This adjustment of the rear view eyewear mirror allows for angular adjustment of the image seen by the wearer. Normal forward vision through the eyewear lens is not impeded by the rear view eyewear mirror. The attachment of the rear view eyewear mirror is semi-permanent because the mirror may be easily removed and re-positioned without scratching or marring the rearward surface of the eyewear lens. The adjustment of the rear view eyewear mirror, once semi-permanently attached to the eyewear lens, remains unaffected by normal use of the eyewear and holds its initial adjustment even when bumped or jarred. The rear view eyewear mirror may be attached to either the right or left eyewear lens for use by the right or left eye, or both.
