The next step is to pre-fit the pinion bearing in the frames. If it's not a tight fit then this could cause pre-mature clutch failure. Install the two frame spacers (the hexagonal white post) that go in front and behind the pinion bearing. Insert the pinion bearing (with the bell attached) into the bottom bearing block of the right frame and then put the left frame on. Use 4 of the HSE3-12B screws to tighten the frames together around the pinion bearing. Now the test... grab the clutch bell and see if you can move it forward and backward. If it's just a small amount then you are probably just feeling the slop in the bearing, however if it moves a few millimeter both directions then you need to file down the 8 spots where both frame halfs touch around the top and bottom bearing block. In the picture below I colored the 4 on the right frame red. I used a grinding bit on my dremel to cut away 1mm from each side. This amount worked out great for mine. Once you get this right, then take the frames apart and go to the next section.
