Fits Models At A Glance:

  • Kubota Compact Excavators: KX040-4

Key Notes:

  • Part Number: RD158-47920
  • Type: Alternator V-belt
  • Belt Size: V 46.5 (46.5" outside circumference)
  • Application: Drives the alternator on the Kubota KX040-4 compact excavator — maintains charging system output by transferring engine rotation to the alternator pulley
  • Condition: Aftermarket replacement part

Common Use Case or Symptoms: Use when the alternator V-belt is cracked, glazed, frayed, or slipping — a worn or broken alternator belt will cause the alternator to stop charging, resulting in a discharging battery, battery warning light illumination, and eventual electrical system failure on the Kubota KX040-4 compact excavator.

Why Choose Broken Tractor:

  • ✅ KX040-4 Specific: RD158-47920 is the OEM-specified alternator V-belt for the Kubota KX040-4 compact excavator — V 46.5 sizing confirmed from the Kubota parts diagram for this model.
  • ✅ Preventive Maintenance Essential: The alternator belt should be inspected at every service interval and replaced at the first sign of cracking or glazing — a broken belt strands the machine by cutting off battery charging.
  • ✅ Fast Shipping from a U.S.-Based Team: In-stock and ready to ship from our U.S. warehouses.
