NOTE:
The default position of spring retainer (A) is flush to the
edge of spring box (B); however, the position of the
spring retainer varies with draper tracking adjustment at
the factory. Illustration shows transparent spring box to
show spring retainer position.

edge of spring box (B)
• Tightened to 6 mm (1/4 in.) inside (D) the front edge
of the spring box (B)
