Piston Stop Tool M14 × 1.25 for Chainsaws

Piston Stop Tool (M14 × 1.25)

A simple and effective tool for locking the piston via the spark-plug hole, allowing easy removal or installation of clutches, sprockets, and flywheels.

• Fits engines using standard 14 mm × 1.25 spark-plug threads (common on most chainsaws)
• Available in Metal or Plastic options
• Manufactured by GA Forestry

Ensure your engine uses 14 mm plug threads before use. Not suitable for 10 mm plug threads.

Warning: Turn the engine by hand only. Do not use impact tools — this can damage the piston.
Note: Clutches and flywheels may use left- or right-hand threads. Check your manual before loosening.
