grooves and seal surfaces for any imperfections and repair or replace as
necessary.
11. Grease all seals and packing liberally and install the bearing assembly and the
piston on the rod. Torque the locknut to 500 ft-lbs.
12. Install the rod into the cylinder tube taking care not to damage any seals or
packing.
13. Align the retainer hole in the bearing assembly groove with the slot in the tube.

bearing assembly clockwise until the retainer is completely inserted in the
groove/slot in the tube.
14. Install the assembled cylinder into the tower with the rod end up and the ports
toward the dock. Line up the upper clevis with the lug in the top of the tower and
insert the clevis pin from the platform side, through the hole in the tower side plate,
into the clevis and lug assembly. Install the pin retainer in the pin. Force the
cylinder barrel down and locate the lower cylinder clevis on the base pad clevis.
Insert the pin through the clevis and lug assembly from the outside of the tower
and install the pin retainer.

Attach the transition hose to the velocity fuse.
16. Turn the electrical supply back on and raise and then lower the platform,
continuing to hold the “DOWN” button about 30 seconds after the platform is fully
lowered. Repeat this 10 to 15 times to purge air from the cylinders and hydraulic
lines. It may take 15 to 30 seconds time to fill the empty cylinders before
movement is noted.
