Top-Quality 12V Starter Motors

The 12V starter motors are designed for small to medium diesel and gasoline engines used in tractors, excavators, mowers, ATVs, and more. In comparison, the 24V motor is used on larger equipment. If you are looking for motors for small to medium diesel and gasoline engines, we'll help you choose the right one.

How to Choose the Right 12V Starter Motor

Before adding to your cart, double‑check these easy steps:

  1. Confirm Voltage: Your machine label or battery will clearly show 12V — don’t mix with 24V systems.
  2. Match the Engine or Equipment Model: Each starter motor is designed for a specific engine family (e.g., Yanmar 4TNV88 or Kubota V2203).
  3. Check the Part Number: Look for an OEM or reference number printed on the old starter or in your manual (e.g., 129900‑77010).
  4. Count the Teeth: Starters can have 8T, 9T, 10T, or 11T pinions — matching tooth count ensures proper engagement.
  5. Review Mount Type & Rotation: Verify flange design and spin direction for direct fit.

When to Replace Your Starter Motor

Replace it if you notice:

  • Slow or no cranking when turning the key
  • Clicking noise from the solenoid, but no rotation
  • Burned smell or visible sparks from the terminal
  • Frequent need to tap the motor to start

A new, high‑quality 12V starter motor ensures fast starts, stable voltage delivery, and less strain on your battery system.
