FIG. 8
Fit the pre-load sleeve (28) and the spring (18) with its spring guide rings (62).
Lift the rod inside the spring by means of a M6 (Ref. 5051) rod and screw the upper plug
(17-17A).
IMPORTANT: the pre-load sleeves up to 30 mm long should be assembled between the
plug and the spring while longer pre-load sleeves should be fitted between the spring and
the damping unit.
FIG. 9
Check that the O-ring (4) and all adjustment unit components are assembled on the plug.
Screw the plug (17-17A) on the rod until the end of the thread and tighten the check nut
(145) against the plug using a torque of 30 Nm (22.1 ft.lb.).
FIG. 10
Lift the stanchion tube and fit it on the plug making sure not to damage the O-ring (4).
Tighten the plug on the stanchion tube using a torque of 25 Nm (18.4 ft.lb.).
ADJUSTMENT
FIG. 11
Brake during compression (l.h. leg) and rebound (r.h. leg) can be adjusted by turning the
knob (162-162A) on the top of each leg. Each adjustment "clicks" in position. In order to
change the adjustment unit position, ALWAYS start with the "completely closed" position,
which can be reached by turning clockwise the knob until it locks. Under these conditions
the maximum braking is reached during compression and rebound. Turn the knob anti-
clockwise until the wished position is reached.
WARNING: Do not force the adjustment knob beyond the maximum closing and opening
position.
FIG. 12
Should either the complete compression setting unit (183) or the complete rebound setting
unit (182) be replaced, there is no need to remove all components, as specified in the
chapter "DISASSEMBLY" . It will suffice to unscrew the stud bolt from the damper rod. First
warm the stud bold in order to melt the "Loctite" used during the assembly and then vice
the damper rod using the proper aluminium blocks and unscrew the stud bolt complete with
the setting unit.
Reassemble the new setting unit on the rod spreading 0.05 g of "Loctite 638" on the thread.
Screw the stud bolt with the setting unit and tighten it on the rod at a torque of 30 Nm (22.1
ft.lb.).
