AEROSHELL FLUID 71Aero<strong>Shell</strong> Fluid 71 is a preservative mineral hydraulic fluid of improvedcleanliness. Aero<strong>Shell</strong> Fluid 71 is composed of a mineral base oil with anadditive package which results in a product with excellent corrosionpreventative properties as well as excellent oxidation stability, and goodanti-wear characteristics.Aero<strong>Shell</strong> Fluid 71 is dyed red.The useful operating temperature range is –54°C to +121°C.PROPERTIES MIL-PRF-6083F TYPICALOil type Mineral MineralKinematic viscosity mm 2 /s@ –40°C 800 max 525@ –54°C 3500 max 2400@ 40°C 13 min 14.3206Hydraulic FluidsAPPLICATIONSAero<strong>Shell</strong> Fluid 71 is intended for preserving hydraulic equipment instorage and also for use in rig testing of hydraulic components.Aero<strong>Shell</strong> Fluid 71 should only be used in hydraulic systems employingsynthetic rubber seals suitable for MIL-PRF-5606/DEF STAN 91-48(Aero<strong>Shell</strong> Fluids 4 or 41) type of fluids. Refer to General Notes at the frontof this section for further information.Aero<strong>Shell</strong> Fluid 71 is compatible with Aero<strong>Shell</strong> Fluids 4, 31, 41, 51 and61.Chlorinated solvents should not be used for cleaning hydraulic componentswhich use Aero<strong>Shell</strong> Fluid 71. The residual solvent contaminates thehydraulic fluid and may lead to corrosion.SPECIFICATIONSU.S.Approved MIL-PRF-6083FBritish Equivalent DEF STAN 80-142FlashpointPensky Martin Closed Cup °C 82 min 88Total Acidity mgKOH/g 0.2 max 0.12Pourpoint °C –59 max Below –59Relative density @ 15.6/15.6°C – 0.879Water content ppm 500 200Colour Red RedTrace sediment mg/l 0.005 max 0.002Oxidation & corrosion stability168 hrs @ 121°C– metal weight change Must pass Passes– viscosity change @ 40°C –5 to +20 Passes– acid number changemgKOH/g 0.2 max Less than 0.2Hydraulic Fluids207French Equivalent to DCSEA 535/ACopper corrosion 3a max PassesRussian –Corrosion inhibition Must pass PassesNATO Code C-635Joint Service DesignationEquivalent PX-26Table continuedwww.shell.com/aviationThe Aero<strong>Shell</strong> BookEdition 18 2003
