Our Experience
United Gear’s mining beginnings included gearbox rebuilds on P&H and CAT hard rock drills. Whether propel, pump drive, rotary, or pulldown we have accumulated the experience to rebuild the key transmissions on P&H 120/320 and BE 49/CAT MD6640 series drills.
Suggested Upgrades
Shown is a double internal ring gear in production for a Bucyrus 49R propel. Given the number of 49R propel rebuilds, we have determined the optimal material and tooth geometry to improve reliability and extend life.
- All replacement components engineered to improve reliability
- Gears manufactured to major international standards including AGMA
- Case carburized gears for reliability
Thermal Imaging of Bucyrus 49R Final Drive
United Gear uses thermal imaging as a typical test protocol depending on the size and application of the gearbox and customer requirements.
