A lubrication/bleeder fitting (10) is provided including a cap (14), a body (12) having a first end (15) coupled to the cap, a second end (17) opposite the first end, and an axially extending cavity (40) extending between the first and second ends. The fitting also includes a poppet seat (50) in the axially extending cavity and a poppet (60) disposed in the axially extending cavity and having a nose portion to seat against the poppet seat. A resilient member (64) is disposed in the axially extending cavity between the poppet and the second end, and a spacer (66) is disposed in the axially extending cavity and seating an end of the resilient member opposite the poppet. The poppet is biased in a first position against the poppet seat by the resilient member to prevent fluid flow through the axially extending cavity.

Systems, apparatuses, methods, and computer program products are provided herein. For example, a method provided herein may include identifying oil pressure data associated with an engine. In some embodiments, the method may include generating adjusted oil pressure data by adjusting the oil pressure data by an engine speed or an ambient pressure. In some embodiments, the method may include generating, by applying the adjusted oil pressure data to an oil pressure residual model, oil pressure residual data indicative of one or more oil pressure residuals. In some embodiments, the method may include generating, by performing a windowing operation on the oil pressure residual data, erratic oil pressure data for a carbon seal associated with the engine. In some embodiments, the method may include initiating performance of one or more responsive actions based at least in part on the erratic oil pressure data.

A dispensing system to apply grease to a lens holder is provided. The dispensing system includes a lens holder cavity adapted to accommodate a lens holder and a loading area. The loading area includes a damping grease cartridge to accommodate the grease. The dispensing system includes a nozzle apply a predetermined volume of the grease to the inner diameter of the threads. The dispensing system includes a first servo motor to control the height of the lens holder and a second servo motor to ensure a uniform dispense of the predetermined volume grease. The dispensing system is controlled by a programmable logic controller that includes a human machine interface panel adapted to control process parameters. The programmable logic controller and the human machine interface panel are adapted to modify dispensing time, rotation speed, rotation angle to regulate dispensing of the grease.
