For removing the gland with piston in situ using dismantling device 94344 (Fig. ’F’)
the following procedure should be observed:
⇒ Turn the piston to B.D.C.
⇒ Dismantling device 94344 (2-part) as shown in Fig. ’F’ is to be set on the stud
nuts of the crosshead/piston rod connection and both halves of the disman-
tling device are to be screwed together.
⇒ Loosen and remove the four outer screws 14 from 2-part ring 15 (Fig. ’B’).
⇒ Turn the piston with the mounted dismantling device carefully to T.D.C. until
2-part ring 15 is pushed a little upwards (Fig. ’F’).
