b) Lubricate the threads and the interior wall of the cylinder.
c) Position the cylinder assembly of the lower grip into the environmental chamber. Move the cylinder
assembly through the hole in the environmental chamber. Align it with the threads of the hydraulic
chamber.
d) Rotate the cylinder until you feel the thread ends engage. Hand-tighten the cylinder to the hydraulic
chamber until it is snug.
e) Lubricate the entire lower and bottom ends of the piston extension. Also lubricate the threads of the
socket head bolt. Insert the socket head bolt into the piston extension.
f) Slide the piston extension into the cylinder (narrow end first).
g) Thread the socket head bolt into the hydraulic chamber. Do not tighten it at this time.
h) Repeat Step A through Step G for the upper cylinder assembly and piston extension.
Note:
The piston might slide out of the cylinder when the cylinder end is pointed down.
7. Install the lower wedge chamber.
a) Install the eye bolts on the side of the wedge chamber.
