of the other, inside the reverse clutch retainer. Assemble
both clutch plates so that the places with no teeth (marked
"A") are aligned with the holes in the retainer (marked "B").

2. Install the clutch reaction plate in the direction shown. In the

same way as the clutch plate, assemble them so that the
places with no teeth (marked "A") are aligned with the holes
in the retainer (marked "B").
