5.3.16 Remove the two socket head cap screws that are opposite of each
other on the spring system cover.
5.3.17 Screw the two M8 x 120 threaded rods into the bottom of the spring
cylinder until they bottom out.

cover.
5.3.19 With the nuts holding the spring system cover, remove the remaining
screws.

backing off the nuts. The spring system cover is under heavy pressure.

press, the threaded rod, or the spring box tool method. If the spring
system cover is removed incorrectly, the springs can eject with enough
force to cause serious injury or death!

set.

system cover and screw them into the spring cylinder until they bottom
out.
5.3.25 Compress the springs by evenly screwing the two nuts down the
threaded rods until the spring system cover makes contact with the
spring cylinder.
