adjustment within 1/2 turn of rod end.
CAUTION: DO NOT DISTURB VENDOR INSTALLED LOCKWIRE.
2) Loosen fine adjustment jamnut and adjust (rotate) fine adjustment hex until holes in rod end and thrust crank are aligned to allow free insertion of bolt. Do not exceed 0.84 inch maximum between cable retainer and fine adjustment hex after adjustment.
3) Use lockwire to check that inspection hole in rod end is completely covered. Install bolt retainer around crank fork and under bolthead. Insert bolt through aligned holes in rod end and thrust crank. Bolt shall fit freely prior to attaching nut.
4) Install locknut on rod end connecting bolt with washer. Tighten nut 50 to 70 pound-inches and bend retainer tab over bolthead (Fig. 504).
