15. To steady the belt block, grasp the belt several inches from the block
and push toward the back of the track until the block is pressed firmly
against the back of the track. While holding the belt with one hand,
compress the springs and swing the car downward until the remaining
wheels are aligned with their groove in the track.
16. While continuing to press the belt block against the back of the track,
release the car so that the stationary wheels engage their groove in the
track.
17. While continuing to press the belt block against the back of the track,
begin to tighten the captive screws. When both screws are partially
threaded into the belt block, release the belt and finish tightening the
screws. Be sure that the block is fully seated against the bracket on the
car. Close and secure the door on the car.

Adding to an Existing Pass-Thru Mechanism
Before reading this section, it may be helpful to familiarize yourself with the
parts and procedures by reading the two preceding sections. To add to an
existing Pass-Thru mechanism, you must first partly disassemble it, then make
the necessary changes as described in the preceding sections. Use the
following procedure for disassembly.
1. Locate the covers over the drive motor section and the base assembly.
Note that the covers are held in place by nylon button rivet fasteners.
Using a suitable thin-bladed tool, pry up the cover until the fasteners can
be removed. Set the covers aside, and save the fasteners for re-use.
2. Place the Pass-Thru mechanism on a suitable work surface with the
motor at the left and pointed upward. Referring to Figure 3-9, open the
door of the car to gain access to the captive screws. Do not remove the
door. Loosen the captive screws until they are disengaged from the belt
block.
3. Grasp the closed side of the car and pull it toward you so as to compress
the springs underneath the car. When the wheels on the closed side are
clear of the track, lift the car from the track and set it aside.
