To Refit
Refitting is a reversal of the removal instructions. It is recommended that new O
rings are fitted to impeller end face and shaft and a new pair of lockwashers are
fitted before refitting the impeller nut which should be tightened to 400Nm (295 lbs ft)
torque. To refit front cover plate, a new O ring should be fitted to the cover plate
spigot before assembly.
Rear Wear Ring
The rear wear ring (accessible after the removal of the low pressure impeller) is
retained by 4 off M8 socket head screws. After removal of these screws, the rear
wear ring may be jacked out by means of two screws inserted into the adjacent
tappings.
