Key Notes:

  • Part Number: T152876
  • Weight: 41.00 lbs (18.60 kg)
  • Splines: 27
  • Teeth: 6
  • Configuration: Without clutch — fits both single input and dual input circle drive configurations
  • Dimensions: 11-3/4 in × 11-3/4 in × 15-1/2 in
  • Type: Circle drive pinion — the output gear in the circle drive gearbox that meshes with the internal ring gear on the blade support circle to rotate the motor grader blade left and right during grading operations
  • Application: Driven by the hydraulic motor through the circle drive gearbox; the pinion teeth engage the circle ring gear to swing the blade to the desired cutting angle; a wear item that degrades with heavy circle use, especially under high lateral blade loads
  • Availability: Currently out of stock — call for lead time
  • Origin: Made in USA
  • Manufacturer: PVE Products

Common Use Case or Symptoms:
Use when circle rotation is sluggish, jerky, or makes grinding noise, or when visible tooth damage, spalling, or excessive backlash is detected on the drive pinion — worn or broken pinion teeth transfer uneven force to the circle ring gear, accelerating ring gear wear and reducing blade angle control.
