Abstract: A linkage pin joint assembly may include a portion of a first machine member having a first bore, a portion of a second machine member having a second bore, and a linkage pin pivotally interconnecting at least the first and second machine members. The linkage pin may extend between the first and second machine members, and be positioned at least partially within the first bore of the first machine member and the second bore of the second machine member. The linkage pin may extending at least partially through the first and second bores and pivotally support the first and second machine members relative to each other. The linkage pin may be coated with a diamond-like carbon (DLC) coating over at least a portion of an outer diameter surface of the linkage pin, the coating providing a contact layer between the outer diameter surface of the linkage pin and at least one of a mating inner diameter surface of a joint bushing positioned within one of the first and second bores through the first and second machine members and a mating inner diameter surface of one of the first and second bores.

Abstract: An undercarriage track joint assembly includes a first link having a first bore at a first end and a second bore at a second, opposite end, and a second link having a first bore at a first end and a second bore at a second, opposite end. A pin may extend between the first and second links, positioned at least partially within the first bores of the first and second links, or partially within the second bores of the first and second links. A bushing may extend between the first and second links, a central axial bore being defined through the bushing. The pin may extend through the central axial bore through the bushing, the pin being coated with a diamond-like carbon (DLC) coating over at least a portion of an outer diameter surface of the pin, the coating providing a contact layer between the outer diameter surface of the pin and an inner diameter surface of the central axial bore through the bushing.

Abstract: A fuel injector system includes an injector body having a proximal end and a distal end, the injector body defining a nozzle having an outlet. The injector system includes a spill valve fluidly connected to the outlet and having a spill valve member movable between an open position and a closed position. The injector system includes a control valve including a control valve member movable between an open position and a closed position. The injector system includes a check valve fluidly connected to the outlet, the control valve including a check valve needle movable between an open position and a closed position. The injector system also includes an electrical monitoring circuit configured to output a signal indicative of at least one of the open position or the closed position of the spill valve member.
