How do the 10mm and 14mm piston stops help during clutch removal?

The metal piston stop pins hold the piston steady while you loosen or remove the centrifugal clutch, preventing rotation and reducing the risk of damage. Having both 10mm and 14mm sizes covers common piston diameters used across the compatible Husqvarna models. Use the size that matches the piston bore to ensure a secure, non-marring hold.

• 10mm and 14mm pins included to match different piston sizes
• Pins are metal for durability during repeated use
• Stops stabilize the piston to allow safe clutch removal
