Improved Hydraulic Pump Outlet Hoses
For longer life and improved reliability, high-impulse hoses with a 3,000 psi (20 684 kPa) and 3,500 psi (24 131 kPa) maximum operating pressure are now used as the 7-gallon-per-minute (26 L/min) and 26-gallon-per-minute (98 L/min) hydraulic pump outlet hoses, respectively. They replace 2250 psi (15 513 kPa) hoses on the 580SE.
Bolt-on Split Flanges
For improved serviceability and protection against leaks, bolt-on split flanges are used to connect the hydraulic pump outlet hoses.
