The swingfunction is powered by its own variabledisplacementpiston pump.■■■■■Main pumps are each rated at aconservative 375 lpm (99 gpm) foroptimum service life.The swing pump is rated at 450 lpm(119 gpm).Other, smaller pumps power thecooling fan drives, pump drivecooler, pilot system, automatic tracktensioning system, and A/C system.All pumps are serviced throughCat dealers.A bulkhead separates the engine andpump compartments.The modular design of the 5130Bprovides unique advantages in hydraulicsystem design and serviceability.■■The longitudinal mounting of the3508B engine and the low placementof the hydraulic pumps eliminate theneed for a pressurized hydraulic tank.Walk-around, lighted access to allhydraulic system components allowseasy serviceability and quick dailymaintenance checks.Hydraulic system filtration is providedby 200 micron screens in the pumpdischarge lines and 10 micron filtersin the return lines and case drain line.4
