4. Repeat pressure tests after adjusting shackle length. If rear pressures fail specification after adjustment, reposition valve body. Raise valve body if rear pressures are too high, lower valve body if rear pressures are too low.

5. Ensure No. 2 shackle length is within adjustment range. If shackle is removed or replaced, adjust No. 2 shackle to standard length. See NO. 2 SHACKLE LENGTH SPECIFICATIONS table.
