b. Install O-ring (4) line the interior of the end gland. The Syncro Devices assemblies also include a ring
back-up (3) with the O-ring (4).
c. Install O-ring (8) on the body of the piston assembly.
d. Install the spacer into the cylinder body if applicable.
e. Lubricate the areas around the O-rings with hydraulic fluid, slide the end gland on the piston rod and
the piston into the cylinder housing (7).
f. Secure the end gland in the cylinder by installing the snap ring (1) in the annular slot in the Syncro
Devices cylinder. The end gland on the Gar-Kenyon cylinder is secured by threading gland into
cylinder body (7) and securing with safety wire (9).
