8.3 VALVE INSTALLATION
1. Below the deck, at the bottom of the telescoping waterway, verify the external O-ring groove, male threads and composite bearing
ring are clean and dry, using acetone to clean if needed. Apply silicone grease (Moly-Kote 112) to the O-ring groove and threads
only. Install size 242 O-ring in the groove, then apply silicone grease over it.
2. Verify threaded port of valve body is clean with a thin layer of silicone grease applied to the bore and female threads. Install the
valve body onto the waterway threads until it bottoms out snugly. Apply blue Loctite sparingly to the set screw. Install in port
cross-hole and torque to 56 in-lb.
3. Loosen the nuts slightly on the U-bolts of the upper and lower mounting clamps, then rotate the valve to the desired orientation.
Tighten and torque the nuts per Section 6.0, which varies by bracket type.

8.4 PNEUMATIC CYLINDER INSTALLATION
1. Above the deck, rotate the deck plate to an orientation that aligns with the hole in the deck and will allow the pneumatic cylinder to
clear the valve body.
2. Apply blue Loctite sparingly to set screw and begin to install it in the deck plate. With the deck plate pressed down firmly against
the shoulder in the outer tube, torque set screw to 56 in-lb.
3. Loosen the set screw on the upper bracket nearest the outlet of the telescoping waterway, then rotate the bracket until the tab is
facing away from the cylinder mounting hole in the deck plate.
4. Below the deck, install the pneumatic cylinder through the deck and deck plate. The cylinder must be oriented such that the
plumbing falls into one of the two notches on the bottom of the deck plate. While holding the cylinder up against the deck plate,
install the band clamp spacer as low as practical between the telescoping waterway and the pneumatic cylinder.
5. Above the deck, have an assistant apply blue Loctite to the cylinder threads and tighten the nut until it is snug. Torque the nut to
130 ft-lb using a 1-7/8” wrench.
6. Below the deck, wrap the band clamp around the pneumatic cylinder, spacer and telescoping waterway such that the two ends
are touching the telescoping waterway. Tighten the nut and torque it to 43 in-lb.
7. Above the deck, apply a linear stripe of blue Loctite along the threads of rod on the pneumatic cylinder, from the end of the rod up
to the jam nut. Twist the upper bracket to align the clevis with the rod, then tighten the rod into the clevis two turns using a ½”
open-end wrench.
8. Apply blue Loctite sparingly to set screw of the upper bracket and begin to install it. With the bracket lifted firmly against the
shoulder of the inner tube, torque set screw to 56 in-lb.
9. Continue to tighten the rod counter-clockwise into the clevis. Stop when the upper bracket lowers to contact the outer tube, then
tighten the rod counter-clockwise an additional ¼-turn.
10. With a wrench on the shaft to prevent rotation, tighten the jam nut and torque it to 40 ft-lb using a ¾” wrench.
11. Provide the directional control valve inlet with a pneumatic hose having a pressure between 80 PSI and 130 PSI.
12. Verify that the LOCK position of the manual override pin
is not obstructed by the pneumatic cylinder. If it is
obstructed, use 1/8" hex driver to loosen the button head screw on the cable tether bracket. Apply blue Loctite to screw and install
the tether bracket, screw and override pin on the opposite side of the waterway.
