Playing a critical role in the braking systems of heavy machinery, the component with part number 419-33-21720 is fully compatible with the hydraulic brake mechanism of WA320 series loaders. Designed in accordance with original manufacturer standards, this metallic element maintains component integrity even under intense field conditions, supporting the continuity of stopping performance.
Compatible Machines and System Notes
Playing a role in the conversion of hydraulic pressure into mechanical movement in Komatsu brand construction equipment, this part with reference 4193321720 is used in the brake assemblies of WA320-3, WA320-5, WA320-6, and WA320-7 generation loaders. During replacement, checking the sealing elements and hydraulic oil within the system is important for the stable operation of brake hydraulic pressure.
In heavy machinery brake systems operating under excessive load, regular maintenance and hydraulic fluid cleanliness are among the factors that directly affect the lifespan of piston surfaces. To clarify part compatibility during hydraulic system overhauls, the machine serial number and the code 419-33-21720 must match. You can evaluate these technical details for your required WA320 brake piston order.
