Install Servo Motor or Gearhead

1. Remove key from motor shaft.

2. Slide the gear head bushing into the drive coupling

and align slots in drive coupling and bushing. See

IG. 19.

3. Rotate the drive coupling to align clamping bolts

with access holes.

4. Place motor on work surface with motor shaft facing

straight up then mount the gear head. Mounting the

gear head in any other orientation will usually lead

to misalignment and excessive noise.

5. Pre-torque drive coupling to 0.4 N•m (4 in-lb).

6. Bolt gear head to the motor with fasteners provided.

7. Final toque drive coupling to 8.5 N•m (76 in-lb) in

three steps increasing torque each time.

8. Do not tighten coupling to gear head output shaft

until drive assembly is mounted in frame.

NOTE: Orient servo motor so that the motor connec-

tions do not interfere with material inlet hose.

9. Install gussets with shoulder bolts (5, 1104).

Remove Coupling

1. Prepare Gear Meter Assembly for Repair,

page 37.

2. Remove support gussets (9, 1106).

3. Remove bolts (1, 1103) connecting top mounting

plate (8, 1105) to vertical mounting plate (10, 1107).

4. Remove servo motor, gear head, and top plate.

NOTICE

Use caution when handling servo motor to prevent

damage. Do not use tools that could cause dam-

age.
