2. Inserting The Screw Shaft

Insert the screw shaft into the casing until the end face of the main bearing holder makes

approximately full contact with that of the casing (i.e., the mounting surface of fixing plate of

the main bearing holder).

For this process, wear leather gloves to prevent hand injuries. (Do not use fabric work gloves.)

The screw shaft is heavy, and the main bearing holder rotates, making it difficult to hold it.

Be careful not to drop the screw shaft during installation.

3. Positioning screw rotor

Mount the jig (3) onto the main bearing holder and casing. In order to make adjustment of

the direction and position of the screw rotor shaft, put the screw adjusting shims (1) between

the jig and the main bearing holder, by the same height as that at the disassembly.

4. Installing The Motor Rotor

(1) Mount the jig (3) onto the main bearing holder and casing.

(2) Insert the motor rotor key into the screw shaft from the suction side, and insert the motor

rotor.

Insert the motor rotor in the direction shown below.
