 CAUTION: MAKE SURE THE TOP AND THE BOTTOM OF THE THRUST REVERSER SLEEVE
_______
 MOVE TOGETHER WHEN YOU MOVE THE THRUST REVERSER SLEEVE ON THE
 TRACKS. IF THE TOP AND THE BOTTOM DO NOT MOVE TOGETHER, YOU
 CAN CAUSE DAMAGE TO THE "RULON J".

 MAKE SURE TO CORRECTLY ALIGN THE TRACK SLIDERS AND THE TRACKS BEFORE YOU TRY TO MOVE THE THRUST REVERSER SLEEVE. IF THEY ARE NOT ALIGNED, YOU CAN CAUSE DAMAGE TO THE "RULON J" LAYER WHICH WILL DECREASE THE PERFORMANCE OF THE THRUST REVERSER SLEEVE.
 (4)  Align the track sliders with the tracks.
 NOTE: If necessary, you can add a radius of 0.005 to 0.015 at the
____ entry and of the "Rulon J" on the main slider of the thrust reverser. This could make it easier to install the thrust reverser sleeve.
