About the Komatsu PC45R-8 Mini Excavator

MWE offers OEM quality replacement tracks and undercarriage for the Komatsu PC45R-8 Mini Excavator from MWE, Camso, and Bridgestone. Our tracks feature continuous steel (joint-less) cords and are constructed from virgin (non-recycled) rubber, strong enough to handle even the most extreme applications. Our tracks are chunk and tear resistant thanks to natural rubber compounds that minimize vibration and offer a smoother ride, handling, and performance for your Komatsu PC45R-8.


Select from a wide range of tread patterns including Block, Multi-Bar, C-Pattern, and Blizzard that can provide both traction and flotation in a wide variety of applications. We have tracks for the Komatsu PC45R-8 in standard width, in addition to wide and narrow fitments. Choose a wider fitment to extend track life and minimize ground damage or use a narrow fitment for tight spaces.


Whatever your job requires, we have Rubber Tracks and Replacement Undercarriage Parts for your Komatsu PC45R-8 Mini Excavator at a savings nearly 50% less than dealer pricing.
