QS 0000 997 5625
Clutch tensioning spring from Stihl. Clutch springs loose their tension over time, especially when the clutch drum is heated up. Once they loose their tension, the clutch will always be engaged, even when the saw is at idle, making for an unsafe chainsaw. Clutches usually require 3 springs.
