TIP
The spring preload setting is determined by
measuring distance A, shown in the illustra-
tion. The longer distance A is, the higher the
spring preload; the shorter distance A is, the
lower the spring preload.
3. Tighten the locknut to the specified
torque. NOTICE: Always tighten the
locknut against the adjusting nut, and
then tighten the locknut to the speci-
fied torque.
