The component with part number 424-15-12221 is one of the key elements ensuring power transmission in heavy machinery drive systems. This transmission gear, coded 4241512221, is designed to be compatible with WA420-1 and WA400-1 models.
Compatibility and Assembly Details
During gear replacements in transmission systems, shaft keys, bearing bushings, and shim thicknesses must be meticulously inspected. In such power transmission components exposed to heavy working conditions, the condition of gear profiles and shaft fit tolerances directly affects the working life.
Points to Check
- Whether there is wear or pitting on the tooth surfaces
- Compatibility of the internal spline channels with the shaft
- Torque transmission balance during operation
To ensure the accuracy of the part code for your WA420-1 or WA400-1 series loader, you can verify which transmission group it will be used in.
