  • Gearbox Preventative Maintenance is a Priority
    . When misalignment occurs cracks can develop at the end of a gear tooth causing helical and bevel gearing to fail. Wear caused by vibration can cover a broader range of gear damage, from scoring and galling to abrasive wear and plastic yielding. Plastic yielding can occur on gears subjected to heavy
