Components ensuring hydraulic pressure management in the braking systems of heavy-duty machinery play a direct role in the stability of stopping performance. Designed for the WA320-1 and WA300-1 series loaders used in the Komatsu machinery series, this part balances hydraulic fluid with mechanical force transmission. During the assembly stage of the part, the cleanliness of the hydraulic lines, the condition of the sealing elements, and housing tolerances must be inspected with precision. Checking wear limits during maintenance processes is among the critical steps that extend the system's lifespan. Offering full compliance with the original system form, the part number is recorded as 419-44-12120 or without hyphens as 4194412120. With the 419-44-12120 Komatsu WA320 Brake Buster Piston part carrying this reference number, hydraulic losses in the brake center are prevented.
The operating lifespan of piston elements in hydraulic brake buster systems depends directly on the cleanliness of the fluid used and operating temperatures. During periodic maintenance, seal housings and shaft surfaces should be thoroughly reviewed.
You can choose this part for the brake system of your Komatsu WA320 model loader.
