D) When the components are disassembled, they should be properly cleaned, and wear checked prior to being greased and reas-
sembled. In case the sealing parts are too much worn out use new parts from the spare parts kit.
Assembly.
A) O-ring (part N° 12) shall be greased and mounted onto the piston seat using a proper conical tool that allows an easy and perfect
slip-in of the items without any damages.
B) Push into its piston seats the supports (part N° 7).
C) Grease the pistons (part N° 2) on the replaced parts (parts N° 7+12).
D) Grease the internal cylinder surface (part N° 1).
E) Position the scotch-yoke shaft (part N° 4) in order to have the groves in position for the pistons insertion (see Fig. B) and the right
shaft required direction of rotation.
F) Insert the pistons (part N°2) in the scotch-yoke grooves (part N° 4) and press simultaneously the two pistons inside of the cylinder
(part N° 1). The ACTUATECH scotch-yoke system will avoid pistons misalignment. Holding the actuator on a vice rotate the shaft to
verify the shaft rotation direction and the easy movement.
G) Replace the cap seal (part N° 8) on its caps seat (part N° 3) and grease it. Fit the end caps to the body screwing the screws in
cross (part N° 16).
N.B. For the screw torque wrench setting see pg. 8.
