Extract most of the screws securing the inlet cover to the main casing. Remove the dowel pins
locating the inlet cover to the main casing (Fig.44). Remove the rest of the screws and carefully
slide the inlet cover over the extended shaft of the male rotor, taking the ‘O’ ring seal with it taking
great care to avoid damaging the inlet end journal bearings, which are situated in the inlet end cover
(Fig. 45).
