Abstract: Apparatus and method for leak testing and adding lubricating oil to enclosed reservoirs of undercarriage components of crawler-type equipment. Barometric pressure is measured by a transducer mounted on a handle from which an elongated wand extends, the wand having a nozzle on the end opposite the handle. The wand is inserted into the reservoir and communication is successively established and terminated between the handle and a source of pressurized nitrogen, a vacuum generator and a source of lubricating oil. After raising the pressure in the reservoir by connecting it to the nitrogen source, pressure is again measured at the end of a wait period to determine if the drop is greater or less than a predetermined amount indicating seal integrity.

Abstract: An apparatus for crimping connectors on the ends of hoses includes a clamping machine having first and second moveable portions, a first measuring device associated with the clamping machine for delivering a signal representative of the linear distance between the moveable portions, and a controller operatively connected to the first measuring device and the clamping machine, for receiving the signal and stopping the relative movement of the first and second moving portions when the signal reaches a predetermined setting. The controller adjusts the relative movement of the moveable portions in response to input recorded on crimped connectors.
