3.4.8 Equalisation Valve Replacement
There are two equalisation assemblies. The upper equalisation assembly is
connected to the outlet manifold assembly whilst the lower equalisation
assembly is connected to the inlet manifold assembly as shown.
The procedure for replacing the cylinders is the same for both the upper and
lower assemblies.
Remove the tubing from the cylinder.
Remove the 1” BSP VSR plug from the plate.
Whilst supporting the assembly, remove the 8 off M10 Hex HD bolts that hold
the equalisation plate and the strike plate from the assembly.
Carefully withdraw the plate from the shroud and place it onto a clean surface.
To remove the valve disc assembly from the cylinder, 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 shaft.
Remove the cylinder from the equalisation plate by unscrewing the M6 socket
head screws.
Replace the nose seal and fit the replacement cylinder 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 bolt and then attach the valve disc
assembly onto the cylinder.
If the exhaust valve is to be replaced go to procedure 3.4.10. Otherwise replace
the o-rings, located in the machined grooves of equalisation plate and strike
plate, and re-attach the assembly to the generator using the 8 off M10 bolts.
Torque the bolts down to 34Nm (25ft lb)
Refit the 1” BSP VSR plug into the equalisation plate.
Reconnect the tubing to the cylinder.
Repeat the process for the other equalisation assembly.
