3.4.7 Outlet Valve Replacement
The outlet plate assembly is located below the upper manifold as shown.
Disconnect the inlet pipe-work, including the ball valve, from the port marked
“Compressed Air Inlet”.
Ensure that the pipe-work remains adequately supported whilst disconnected
from the generator.
Remove the tubing from the cylinders.
Whilst supporting the assembly, remove the 8 off M10 Hex HD bolts that hold the
inlet / outlet plate onto the strike plate.
Carefully withdraw the plate from the shroud and place it onto a clean surface.
Remove the remaining 1” BSP VSR plug from the plate.
Note: The plug may be located on either side of the plate depending upon which
side of the generator the outlet pipe-work is connected.
To remove the valve disc assemblies from the cylinders, insert a 10mm spanner
through the VSR plug hole onto the machined flat on the cylinder shaft.
With the cylinder shaft held securely, loosen the M6 Hex head stem bolt that
holds the discs onto the shafts.
Remove the cylinders from the inlet / outlet plate by unscrewing the M6 socket
head screws.
Replace the nose seal and fit the replacement cylinders to the plate
Torque the bolts down to 20Nm (15ft lb)
Assemble the valve discs onto the M6 x 25L stem bolts in the following order:
M6 anti vibration washer.
20mm ALU disc
31mm Poly disc
35mm ALU disc
Apply thread lock adhesive onto the stem bolts and then attach the valve disc
assemblies onto the cylinders.
Replace the 2 o-rings located in the machined grooves of the inlet / outlet plate
and re-attach the plate assembly to the strike plate using the 8 off M10 bolts.
Torque the bolts down to 34Nm (25ft lb)
Refit the 1” BSP VSR plug into the inlet / outlet plate assembly.
Reconnect the tubing to the cylinders.
