Serving as one of the key components that support the stable operation of powertrain systems in heavy machinery, the part coded 425-46-12232 is preferred for replacing worn bushings under severe field conditions. The exact part reference number 425-46-12232 (also formatted as 4254612232) ensures a direct match during the overhaul of compatible undercarriage and differential systems.
WA500 Series Differential and Cradle Structure
Located in the rear cradle mechanism of Komatsu WA500-1 and WA500-3 loader models, this bushing stabilizes axle movements and minimizes friction at high-load points. Measuring the housing diameter during replacement and thoroughly cleaning the surfaces prior to installation directly extends the working life of the new part.
Assembly and Replacement Notes
Appropriate press tools must be used when removing and realigning differential carrier sections in heavy-duty loaders. To ensure the health of the rear differential assembly, it is important to check bearing clearances against guideline values during bushing replacement. You can safely complete the powertrain maintenance on your WA500 series loader with this 425-46-12232 coded bushing featuring the correct part reference.
