ABSTRACT:
A modular oil monitor for a gas turbine engine includes a mounting pad having a seat with a plurality of oil inner ports disposed therein and joined in flow communication with an oil tank and an oil sump of the engine. A module having a base is removably fixedly joined to the seat, with the base having a plurality of oil outer ports disposed therein and joined in flow communication with respective ones of the inner ports. The module also includes a filter circuit disposed in flow communication between first and second ones of the outer ports, with the filter circuit including an oil filter removably joined to the module for filtering supply oil channeled therethrough. A first sensor is removably joined to the module for measuring the oil temperature or pressure. The module provides at one location various lubricating system components which may be individually inspected or replaced. Or, the entire module may be replaced in one operation.
