Direct from the Source

By getting a certified Kato or Leroy-Somer replacement part, your generator will achieve increased performance and prolonged uptime between inspections and maintenance operations.
Alternator components, especially electronics, endure a high level of stress. Quality of materials, precision in assembly and a high tolerance level for the whole design are therefore essential elements to guarantee the durability of any component of the machine.

  • Direct order through our helpdesk or online
  • Approved reseller

Always make sure to buy your spare parts from trusted sources:
There are many counterfeit alternator spare parts out there, especially AVRs, which are a critical component to monitor and use alternators. A counterfeit AVR can mean fatal short circuits, poor performances and weak construction.
