It has been carefully tested by the manufacturer to ensure OEM standards and efficient performance. EASY TO INSTALL: It only takes a few minutes to repair. Use a flat-head screwdriver to pry off the clutch, wipe the threads with a dry cloth, and screw on the new clutch counter-clockwise. Wiggle the wrench until the wrench teeth engage the cutout. Once locked, hold the wrench firmly in the locked position with one hand and rotate the clutch clockwise with the other hand. Make sure the blender is unplugged before attempting this repair.
