4  Install the protection sleeve on the actuator.  
5  Install a plastic cap on the electrical connector.  
6  (Rod-end nut at a torque of 6 N.m (- 0/+ 2) (53.10 lb.in (- 0/+ 17.7))).  
(b)  For versions DE  
ACTION  RESULT  
1  Set the Electrical Test Set-Up to get a displacement speed near 1 mm/s (0.0394 in/s).  
2  Set the actuator to the MECHANICAL STOP RETRACTED position (door fully closed) (Ref. to Fig. 1003).  
3  Remove the actuator from the bench.  
4  Install a plastic cap on the electrical connector.  
5  (Rod-end nut at a torque of 6 N.m (- 0/+ 2) (53.10 lb.in (- 0/+ 17.7))).
