A) Drive shaft assembly (Part No. 60), figures 06 and 07:
• Install top and bottom pinion bearings (06) and (07) and top and bottom
pinion O-rings (21) and (22) onto the shaft.
• Grease the outside surface of the drive shaft on
top and bottom as shown in figure 06.
• Insert partially the drive shaft (60) in the body
(50), install octi–cam (01) in the correct position as
shown in figure 07 related to the bottom and top
of the drive shaft and the rotation of the actu-
ator when energised and install internal thrust
bearing (08). Insert completely the drive shaft in
the body.
• Fit external thrust bearing (08), thrust washer (10)
and then external circlip (18) using snap ring pliers.
B) Pistons assembly (Part No. 40), figures 08, 09, 10 and 11:
• Install piston O-rings (16), the Piston skirt (05) and piston head (15) bear-
ings.

teeth.
• Hold the body (50) in a horizontal position by inserting the top of the
shaft into a vice or the bottom of the shaft connection into a male drive
fitted in a vice as shown in figure 08.
• Ensure that the octi-cam is in the right position as shown in figure 09.
• For standard rotation assembly (clockwise to close) rotate the body (50)
about 40-45° counter-clockwise from bottom view or clockwise from
top view depending on which way the shaft has been linked as shown
in figure 10.
• Press the two pistons (40) simultaneously inside the body (50) until the pis-
tons are engaged and rotate the body clockwise from bottom view or
counter clockwise from top view until the stroke is completed.
