Abstract
The apparatus and method for the field measurement of bearing lubricant involves obtaining a control pressure value which is indicative of the pressure which would be generated by injecting a known, controlled volume of air or gas into a test bearing at the existing ambient temperature and pressure. Then, the same controlled volume of air or gas is injected through a valve controlled opening in the test bearing housing by an injection fixture which is sealed to the housing and which is connected to an injector for such controlled volume. Once the controlled volume is injected, the actual pressure in the test bearing is sensed and compared with the control pressure.
