9. <Continuous capacity control unit> Installation of control motor

(1) Preparation

 Rotate the control motor in the direction shown in figure below (subject to models) until it

lightly hits the end of rotation and then mark this hit point on the drive shaft and bushing.

(This light hit point means a place where the Type E retainer ring of the pilot valve makes

contact with the end face of the piston shaft. At this time, the slide valve, piston, etc., are

located on the minimum load side.)

Caution When the drive shaft makes contact with the end of rotation, do not rotate it further.

Furthermore, do not rotate the drive shaft by 60 degrees or more in the counter-rotation

direction.

 In order not to rotate the drive shaft, remove the lever.

(2) Installation

 Use a new control motor. (In accordance with information in Section 4-2, check to be

sure that the control motor is in its 100% position. If it is mot in the 100% position, follow

information in Section 4-2, passing a voltage through the control motor.)

 Put insulation material in place first, and then insert the control motor in the drive shaft.

After that, install the discharge end cover via the insulation material. (See Fig. 4-21.)

 Apply a thread lock compound (e.g. Loctite No. 222) to the locking screw and then

tighten the screw onto the drive shaft. (See Fig. 4-21.)
