A radar sensor assembly that includes a radar sensor and a holder assembly is provided. The holder assembly includes a base plate, a first wall, a second wall, a third wall, and a bottom wall. Each of the first wall, the second wall, and the third wall extends from the base plate, and along with the bottom wall, define a sensor-holding portion. The first side and the second side define a sliding side to allow slidable accommodation of the radar sensor, in the sensor-holding portion. The sliding side includes a retention tab, which depresses to facilitate sliding of the radar sensor into the sensor-holding portion, and lifts to retain the radar sensor in the sensor-holding portion. At least one of the first wall, the second wall, and the third wall, includes one or more retention elements that prevent displacement of the radar sensor.

A coupler comprising a tip mounting portion and an implement mounting portion. The implement mounting portion defines an implement pocket with a central wall having an abutment surface and a coupler side wall having a distal end adjacent the central wall and a proximal end. The side wall has a side interior surface facing the implement pocket and adjacent the abutment surface. The side interior surface defines a recessed portion adjacent the abutment surface. The recessed portion is offset laterally outward of the side interior surface. The side wall has a base portion at the proximal end with a base exterior surface and an interlock portion at a distal end of the coupler side wall that has an interlock exterior recess surface, the base portion width greater than the interlock portion width. The recessed portion extends between the abutment surface and a transition surface, spanning the interlock portion.

A hydraulic piston system includes a housing that defines a piston pocket and a fluid inlet. A piston with a peripheral region and an end is movable within the piston pocket of the housing. The end of the piston has peripheral defined channels and a portion structured and arranged to engage the housing to limit travel of the piston. Further, a seal is configured to seal the peripheral region of the piston against the piston pocket. The seal is structured and arranged to receive fluid pressure when the piston is positioned with the portion of the piston is in engagement with the housing and fluid communication exists between the fluid inlet and the seal through the peripheral defined channels.

The present disclosure is related to a method of determining a height of an upper surface of an insert relative to a top deck surface of a cylinder block. The method includes detachably coupling a fixture to the top deck surface of the cylinder block. The method also includes disposing a dial gauge on the top deck surface adjacent to each of a plurality of notches defined in the fixture. The method includes inserting a probe of a dial gauge through each of the plurality of notches to contact each of corresponding portions of the upper surface of the insert. The method also includes determining local heights of the upper surface of the insert relative to the top deck surface at the corresponding portions of the upper surface. The height of upper surface of the insert relative to the top deck surface is determined based on the local heights.

A dual fuel injector may be used to inject both gas and liquid fuel into a cylinder of a compression ignition engine. An injector body defines a first set of nozzle outlets, a second set of nozzle outlets, a first fuel inlet and a second fuel inlet. A dual solenoid actuator includes a first armature, a first coil, a second armature and a second coil that share a common centerline. The dual solenoid actuator has a non-injection configuration at which the first armature is at an un-energized position and the second armature is at an un-energized position. The dual solenoid actuator has a first fuel injection configuration at which the first fuel inlet is fluidly connected to the first set of nozzle outlets, the first armature is at an energized position and the second armature is at the un-energized position.
