Slide the new clutch housing over the agitator shaft. Position the housing to sit flush against the gear case.
Place the retaining ring clip around the agitator shaft. There is a 90-degree bend in the wire on one end of the clip. Insert the 90-degree bend into the small hole located in the clutch housing next to the shaft opening.
Hold the retaining ring clip against the four raised flanges on the clutch housing with your fingers. Use a flat-head screwdriver to force the ring clip beneath the flanges of the housing. It may take more than one attempt to push the ring beneath the flanges.
Slide the flat C-clip into the slots located on both sides of the agitator shaft. The C-clip sits directly on top of the ring clip.
Position the tongue and groove pliers around the agitator shaft and the C-clip. Place the top jaw of the pliers on the top of the C-clip and the bottom jaw on the agitator shaft. Squeeze the handles of the pliers to force the C-clip around the shaft, snapping it into its proper position.
