Components that play a critical role in the hydraulic and power transmission systems of heavy machinery directly affect transmission performance. Compatible with WA320-1, WA300-1, and WA180-1 series machines, this mechanical assembly efficiently provides pressurized oil circulation. Replacing filters and transmission oil during part replacement are among the essential procedures to observe in order to extend the lifespan of the new unit.
Maintaining system pressure at the correct levels is of great importance for the stable operation of the torque converter and gear shifting components. During the installation phase, cleaning the flange surfaces and replacing the O-ring gaskets ensures sealing security. During the application process, it must be ensured that this component with part number 705-51-20070 sits perfectly into the mounting slots on the transmission block.
Cleaning in-line debris during transmission pump replacements is necessary to protect the hydraulic circuit. Achieving the correct flow rates in WA320 series loaders is aimed at ensuring the relevant system continues to operate efficiently.
When removing your old unit with the help of a flashlight and measuring tools, you can confirm that you are choosing the right part by comparing the reference code 705-51-20070 or 7055120070 with the original label or body casting on it.
