−
Place the octi-cam (01) through the body (50) onto the
drive shaft (60/60.1). Refer to the Fig. 9-11 for the cor-
rect placement of the octi-cam (01) depending on the ac-
tuator assembly configuration.
−
Place the internal thrust bearing (08).
−
Insert completely the drive shaft (60/60.1) into the body
(50).
−
Place external thrust bearing (08) and thrust washer (10).
Risk of spring clip damage due to incorrect assembly.
During reassembly the spring clip (18) can get overstressed if
not carefully handled.
Î

Refer to Fig. 9-1, Fig 9-12, Fig 9-13 and Fig 9-14.
Proceed as follows to reassemble standard 4
th GU series actu-
ator pistons with a 90° angle of rotation and clockwise to clo-
se. Refer to the TYAS technical data sheet in case of actuators
with different function/rotation.
−
Lubricate and place onto the pistons (40) the o-rings (16),
piston backs (05) and the head bearings (15).
−
Lubricate the internal surface of the body (50) and the pis-
ton (40) rack teeth.
−
Insert the female connection of the drive shaft (60/60.1)
in a properly fixed coupling joint. (Fig. 9-13)
−
Make sure that the octi-cam (01) is in the right position as
per the Fig. 9-13.
−
Rotate the body (50) about 40°-45° clockwise from top
view, as shown in Fig. 9-14.
−
Insert and press the two pistons (40) simultaneously inside
the body (50) until the pistons are engaged.
−
Then rotate the body (50) anticlockwise from top view un-
til the stroke is completed.
