Two main track sliders attach the inner sleeve to the tracks in the hinge beam and latch beam and carry most of the weight of the thrust reverser sleeve. Two auxiliary track sliders attach the outer sleeve to the tracks in the hinge beam and latch beam.
The thrust reverser sleeve is moved aft to the extended position and forward to the retracted and stowed position by the thrust reverser actuation system. There are three access panels in the outer sleeve to get access to the rod end fittings for the thrust reverser hydraulic actuators.
Training Information Point
The thrust reverser sleeve weighs approximately 425 pounds (193 kilograms) and requires special ground support equipment (GSE) for removal and installation.
You must go into the fan duct to disconnect the drag links from the blocker doors when you remove and install the thrust reverser sleeve. Make sure the soles of your work boots are clean of unwanted material. Use boot socks over your work boots or use a protective mat to protect the composite surface of the sleeve.

THRUST REVERSER SYSTEM -TRACK SLIDERS

Purpose

The thrust reverser track sliders permit the thrust reverser sleeves to move forward and aft in the tracks.
Location

The main and auxiliary track sliders are on the top and the bottom of each thrust reverser sleeve.
Physical Description

Two main track sliders attach the inner sleeve to the tracks in the hinge beam and latch beam. The main track sliders carry most of the weight of the thrust reverser sleeve.
Two auxiliary track sliders attach the outer sleeve to the tracks in the hinge beam and latch beam. Because the outer sleeve is only attached to the inner sleeve at the aft end, the auxiliary track slider is the forward structural element that holds the outer sleeve in place. If the auxiliary track slider is missing, the outer sleeve is no longer held in position and could be damaged by the airflow.
The main track sliders and the auxiliary track sliders have a wear surface that reduces the friction between the sliders and the track liners.
Training Information Point
You must remove the thrust reverser sleeve to do a complete inspection of the main and auxiliary track sliders. You must also remove the sleeve to replace the auxiliary track sliders or the wear surfaces on the main track sliders.
WARNING: DO THE DEACTIVATION PROCEDURE TO PREVENT THE OPERATION OF THE THRUST REVERSER. THE ACCIDENTAL OPERATION OF THE THRUST REVERSER CAN CAUSE INJURIES TO PERSONNEL AND DAMAGE TO EQUIPMENT
