Additional information It is advisable to run-in the pinion beforehand to remove excess grease from the mechanism and ensure the correct seating of the triggers. This process can be speeded up by pouring a little oil into the groove between the center of the pinion and the teeth. If the sprocket is used for trials without first seating the triggers, it will not work properly and will cause it to jump, damaging the spline and trigger.
