PERIODIC MAINTENANCE
Rebound damping
NOTICE
ECA13590
Never go beyond the maximum or minimum
adjustment positions.
1. Adjust:
• Rebound damping
a. Turn the adjusting screw “1” in direction “a”
or “b”.
TIP
Although the total number of turns of a damping
force adjusting mechanism may not exactly
match the above specifications due to small dif-
ferences in production, the actual number of
turns always represents the entire adjusting
range. To obtain a precise adjustment, it would
be advisable to check the number of turns of
each damping force adjusting mechanism and
to modify the specifications as necessary.

TIP
The spring preload setting is determined by
measuring the distance “c” shown in the illustra-
tion. The shorter distance “c” is, the higher the
spring preload; the longer distance “c” is, the
lower the spring preload.
Direction “a”
Rebound damping is increased (sus-
pension is harder).
