MAINTENANCE MANUAL
GP/146/99. Issue 9. October 2005
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 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.
