How do I confirm fit before ordering and installing?

Measure the starter and compare its pawl type and housing dimensions with your existing unit. The seller’s images and dimensional notes let you verify fitment quickly.

• Check pawl style in product photos against your current starter.
• Verify rachet diameter (54 mm) and housing diameter (81 mm) match your unit.
• Measure bolt hole spacing: 172 mm center-to-center (triangle) and 199 mm across-center for some 6-bolt types.
• Confirm engine model numbers (GX340/GX390 or clone) and displacement range (337–459 cc).
