Cat HYDO (Hydraulic Oil) - Venequip

MAINTENANCE PRODUCTS & SERVICES® TMCat HYDO (Hydraulic Oil)For use in Caterpillar ® hydraulic and hydrostatic systemsSAE 10WDeveloped, tested and approved by Caterpillar,Cat HYDO (Hydraulic Oil) ensures optimum lifeand performance when used as recommended inCat hydraulic and hydrostatic systems.Recommended useThe preferred lubricant for Cat hydraulicsystems is Cat HYDO. We recommend this oilbecause its additive package provides optimumprotection for components within Caterpillarhydraulic systems. Although more expensivethan lower-performance industrial hydraulic oils,Cat HYDO ensures the best performance andlongest life for hydraulic components.The hydraulic systems of most Cat machinesare filled with Cat HYDO before they leavethe factory.We can help you determine the right oil for yourCat machines and engines. You can also refer toyour “Operation & Maintenance Manual” orService Publication SEBU6250 (CaterpillarMachine Fluid Recommendations). An electronicversion of this service publication is available at:www.CAT.comSimply choose these selections: Products/Partsand Service/Fluids/Machine LubricantRecommendations.The goal of Caterpillar engineers is to designmachines and engines to provide maximumproductivity, long life and low operating costs;Cat HYDO is formulated to help achievethat goal.Typical Characteristics*SAE Viscosity Grade10WColor, ASTM (ASTM D1500)** 1Gravity, API @ 16°C (ASTM D287) 29.6 - 29.9Vickers Vane Pump Test (35VQ25)Appearance (Visual)PassClear and BrightFlash Point, °C (ASTM D92) 226Pour Point, °C (ASTM D97) -30Pumping @ -30°C mPaS (ASTM D4684 MOD) 20,000Viscosity:cST @ 40°C (ASTM D445) 37.7 - 39.2cST @ 100°C (ASTM D445) 6.1 - 6.3Viscosity Index (ASTM D567) 106 - 109Foam Test:***Seq.

Cat HYDO (Hydraulic Oil)Advanced formula for maximumperformance and protectionCat HYDO is formulated with a balanced additive system,including detergents, dispersants, rust inhibitors, anti-wear agentsand defoamers. It offers maximum protection against mechanicalwear, rusting and corrosive wear in Cat hydraulic and hydrostatictransmission systems. Cat HYDO is:• Field proven for consistent performance.• Approved and tested by Cat engineers.• An integral part of Cat machine hydraulic and hydrostaticsystems design.• Standard Caterpillar worldwide factory-fill oil for mostmachine hydraulic systems.A proven balance of additivesCat HYDO contains:• Anti-wear Agents—Zinc dithiophosphate at 1200 ppm (typical)to minimize pump, motor and valve wear.• Emulsifiers—Disperse small amounts of water throughout theoil so water will not damage hydraulic system components.• Defoamers and Air Release Agents—Prevent the formation ofbubbles by reducing oil surface tension to quickly release aircontent to the atmosphere.• Anti-oxidants—Prevent the formation of sludge and corrosiveacids at high system temperatures and pressures.• Detergents/Dispersants—Keep components free of deposits,breaking up contaminants and holding them in suspension.• Excellent rust and corrosion inhibitors to protect metalscontaining iron or copper.S•O•S SM Services for early problem detectionCaterpillar recommends protecting your investment by usingS•O•S Services. Our S•O•S Oil Analysis program is theultimate detection and diagnostic tool for your equipment,helping you head off potential problems before they lead tomajor failures and costly unscheduled downtime.Acceptable SubstitutesIf Cat HYDO is not used, the following alternatives can beused in the hydraulic and hydrostatic systems of Caterpillarmachines.*• Cat DEO TM (Diesel Engine Oil)• Cat TDTO TM (Transmission and Drive Train Oil)• Cat TDTO TMS TM (Transmission and Drive Train Oil—Transmission Multi-Season)• Cat MTO (Multi-Purpose Tractor Oil)• Commercial Heavy Duty Diesel Engine Oil with aminimum zinc content of 900 ppm. (Heavy Duty Oils areidentified by API classifications CI-4**, CH-4**, CG-4,CF-4 or CF.)** However, Cat HYDO should not be used in place of any of theseother lubricants.** API CH-4 and CI-4 oils must also meet the requirements of CaterpillarECF-1 (Engine Crankcase Fluid specification-1).4000 Hour Oil Change Intervals***The drain interval recommendation for Cat HYDO andalternatives is 4000 hours for all machine hydraulic systemcompartments where recommended for use. Oil that is notincluded in the alternatives list should be changed at 2000hours. Cat HYDO should not be used in hydraulic systemsthat contain friction material, except hydraulicexcavators.****Note: Refer to your Operation & Maintenance Manual orService Publication SEBU5250 (Caterpillar Machine FluidsRecommendations) for “Lubricant Viscosities For AmbientTemperatures” recommendations.***For additional requirements, see IRM FLU01-02, “New RecommendedService Intervals for Hydraulic Systems on Caterpillar Machines,” FormNumber PELE0824.****One example of an ineligible compartment is the integrated hydraulicand brake system on certain off-highway truck models.

MAINTENANCE PRODUCTS & SERVICESDo not use industrial hydraulic oilsIndustrial hydraulic oils may shorten hydraulic pump andcomponent life. Often referred to as “AW” (Anti-Wear) oil,these products typically omit or contain reduced levels of theadditive agents listed in this publication. Industrial hydraulicoils are usually formulated to separate water from the oil, adesired characteristic for stationary hydraulic systems.However, in earthmoving equipment this separated water willcause pump and component damage if it is suddenly drawnthrough the system from the tank as the machine moves.Furthermore, during freezing weather such water may formice, causing even more extensive damage.Cat HYDO contains emulsifier additives to disperse smallamounts of water throughout the system, minimizing waterdamage to hydraulic components.Avoid hydraulic oils with specifications that indicate they“separate,” “shed” or “release” water. These oils do notcontain emulsifiers.Cat HYDO contains emulsifiersKeep it cleanAlong with the use of proper hydraulic fluid, oil cleanliness isessential to achieving the full life of hydraulic systemcomponents. New hydraulic oil should be filtered to meet acleanliness of ISO 16/13 or lower when put into Caterpillarmachines to achieve a machine operating cleanliness level ofISO 18/15 or lower. Hydraulic oil that has been removedduring a repair process must be filtered to a minimum of ISO16/13 before it is used to refill. Any used oil should bechecked using S•O•S Oil Analysis before it is reused.After repairs that involve exposing any hydraulic componentto the atmosphere or contamination, a clean-out hydraulicfilter should be installed. See your Caterpillar dealer for partnumbers and more information. Also, an oil sample should betaken within several hours of returning the machine to serviceto assure an operating cleanliness level of ISO 18/15.Hydraulic oil zinc additive levels1200 ppm1000OilOilZinc (parts per million)750500500WaterWater250300Cat HYDOIndustrial Hydraulic OilCat HYDOIndustrial Hydraulic Oil(Typical)Typical industrial hydraulic oils separate water and oil, which cancause valve sticking or excessive wear on your hydraulic system. CatHYDO disperses small amounts of water throughout the oil to ensureproper lubrication.A high level of zinc additives is essential for protecting pumps, motorsand valves from excessive wear. Cat HYDO contains more than twice asmuch zinc as typical (AW) industrial hydraulic oil to maximize yourhydraulic system’s life and performance.

MAINTENANCE PRODUCTS & SERVICESCat HYDO (Hydraulic Oil)Use the best filtersCaterpillar fine-filtration hydraulic filters should be used afterrepairing or opening the hydraulic system and after each oilchange. Do not operate with fine filtration filters for more than100 hours as they will plug more readily than standard filters.We recommend using only Caterpillar hydraulic filters onCaterpillar machines because of their proven ability to trap andhold debris and their exceptional burst strength.Proper use for health and safetyAccording to toxicology information, Cat HYDO has little orno adverse effects if handled and used properly. No specialprecautions are suggested beyond attending to good personalhygiene and avoiding prolonged, repeated skin contact.
