Adjusting the shock absorber
assembly This shock absorber assembly is
equipped with a spring preload adjust-
ing nut.
EC000015
CAUTION:@ Never attempt to turn an adjusting
mechanism beyond the maximum
or minimum settings. @Adjust the spring preload as follows.
1. Loosen the locknut.2. To increase the spring preload
and thereby harden the suspen-
sion, turn the adjusting nut in di-
rection
a. To decrease the spring
preload and thereby soften the
suspension, turn the adjusting nut
in direction
b.
NOTE:@ l
The spring preload setting is de-
termined by measuring distance
A, shown in the illustration. The
longer distance A is, the higher the
spring preload; the shorter dis-
tance A is, the lower the spring
preload.
