A temperature controlled hydraulic fluid supply circuit () includes a first hydraulic fluid reservoir (), that has an initial hydraulic fluid (), and a temperature controlled housing (). A second hydraulic fluid reservoir () is fluidically coupled to the first hydraulic fluid reservoir (), resides within the temperature controlled housing (), and has a controlled hydraulic fluid () that is supplied to a test device (). A circulation device () circulates a temperature altering fluid () through the temperature controlled housing () and adjusts the temperature of the controlled hydraulic fluid ().

System for temperature-controlled testing of hydraulically actuated devices

An apparatus is provided for removing a fastener from a corresponding aperture defined by a workpiece that reduces or eliminates damage to the fastener and/or the workpiece. The apparatus includes a pulling plug for engaging the head of the fastener, and a drive shaft operably connected to the pulling plug. The apparatus further includes a lever member that is urged into operable contact with the workpiece. In operation, the head end of a fastener is engaged by the pulling plug. Thereafter, the lever member is moved into contact with the workpiece. The drive shaft is then retracted while the lever member continues to be urged into operable contact with and to push against the workpiece without positively engaging the workpiece. As such, the pulling plug is also moved away from the surface of the workpiece to remove the fastener from the workpiece.
