Fig. 4-16 Placing alignment marks on casing and main bearing holder
(2) Removing the screw shaft
Push the screw shaft from the suction side until the bearing holder completely extends from
the discharge side. Then pull out the shaft from the discharge side. Insert one hand through
the side cap hole and support the shaft to prevent the screw shaft from damaging the casing
when the screw rotor section comes out of the casing. Use leather gloves during removal to
prevent injuries by the screw and stator.
