Instron (Norwood, Mass.) has launched a maintenance program for servohydraulic testing systems to ensure accurate and repeatable test results and to avoid costly downtime. This new four-point program includes an oil analysis, preventative maintenance, a periodic oil change and a system refurbishment. The hydraulic oil analysis determines the amount of oil deterioration and any contaminant buildup; a comprehensive 41-point preventative maintenance includes a filter replacement, accumulator charging and a hose inspection. Instron's program also includes refurbishing of many system components, if required.
