DISASSEMBLING USING - VICE
It is advisable to unlock the nuts of shock ab-
sorbers’ cap before using the machine GO 312
in order to easy working operations.
Some automotive manufacturers prescribes
to unlock the clamp nuts of the caps before
dismounting the shock absorbers from the car.
Block the strut of the shock absorber inside
the vice in order to center it on the machine
(see fig. 6).
Put the small arms near the spring and insert
the upper vices in the first coil available.
After having found the right position of the
spring on the vice and after having adjusted
the upper vices, block the adjustable arms
(fig.4) locking the screws behind the case with
the key supplied.
Compress the spring using the foot control le-
ver only to release the pressure that the spring
it-self exert on the cap.
Remove the blocking cup form the shock
absorber unscrewing the nut. Discharge the
compression of the spring and replace the old
shaft with the new one.
ASSEMBLING USING - VICE
For assembling make the contrary operations
of the disassembling.
Put the new spring in the same position where
the old one was. Press the foot control lever in
order to make the spring stuck to the blocking
cap.
Block the cap to the shaft of the shock absor-
ber screwing the proper nut.
Now the shock absorber is mounted, use the
foot control lever to release completely the
spring, then move the arms on the outside and
remove the shock absorber now reassembled
thanks to the machine GO 312.
