Cat HYDO (Hydraulic Oil) - Venequip

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.
