The Right Way to Install the AT Series Steering Gearbox

1.Confirm the specifications of the motor and speed reducer, and then clean the mounting surface of reducer and motor.
2.Take out of the buried bolts of the connecting plate and turn the motor locking device until the screws of the locking device are aligned with the hole of the buried bolts.
3. a. Remove the original key on the motor.
b. If necessary, please install the equilibrium bond.
4. Confirm the axis size of the motor, and install the shaft sleeve if necessary.
Note: The correct locking method: When the motor shaft is flat, align the bushing joints in the center line of the flat shaft, and make the locking hoop screw is vertical to the flat shaft.
5. Install the motor upright and lock tightly the screws that attached to gasket with the wrench according to the sequence from 1 to 4 with 5% of the torque value suggested in the Screw torque table ( Table 1)

6. Set up the motor and the reducer upright, and lock tightly the screws of motor locking device with the wench according to the suggested torque in the table 2.
7.Set up the motor and the reducer upright and lock tightly the screws with the wrench according to the sequence from 1 to 4 with the torque value suggested in the Screw torque table ( Table 1).
8. Lock back to the buried bolt.
