Chapter 2 Upgrade Procedure Assembly Procedures Assembly of the Pass-Through mechanism (“the mechanism”) requires experience working with moderately complex mechanisms, and the ability to follow directions carefully. The following sections first provide an overview of the parts and procedures required to assemble and install the mechanism. It will be useful to read these sections through before beginning work.

Mechanism External Parts NOTE: The slide extensions, (6) in Figure 2-1, are not enclosed with the mechanism parts. They are supplied as part of the installation hardware for the slides that come with each of the modules. The rails for each rack type might be different but the mounting scheme is the same.

2-4 Pass-Through Mechanism Expansion Kit Installation Instructions The belt block is fastened to the back of the car with two captive screws (Figure 2-3). Make a careful note of the orientation of the block with respect to the car. Orienting the Parts During Assembly To determine the orientation of an extension section examine the flanges on the edges of the section and note that they are dissimilar. Position the section so that its orientation matches that of the elevator base.
Upgrade Procedure 2-5 2 1 1 3 4 5 1 SHR-1236 Support brace; Motor section drive; Extension section; Tie bar; Base section. Figure 2-4. Assembled Mechanism Assembling the Mechanism You need a clean, flat work area such as a table or work bench. The surface should be long enough to support the full height of the mechanism. The height is equal to the height of the stack of modules in your system plus any gaps you intend to include in the stack.
2-6 Pass-Through Mechanism Expansion Kit Installation Instructions 1. Place the base section (Figures 2-1 and 2-4), with the inside facing down, overhanging the right end of the work area, with the bottom plate of the section toward the right. 2. Place each of the extension sections, with the inside facing down, in a row aligned edge-to-edge beginning with the base section. The bottoms of the sections should be toward the right. Omit the motor drive at this time. 3.
Upgrade Procedure 2-7 Installing the Belt Do these steps to install the belt. 1. Turn the assembled mechanism over so that the motor points upward. 2. Locate the tensioner ramp in the base section (Figure 2-5). Compress the spring until the hole in the tensioner ramp is aligned with a hole in the base section. Insert an 0.050" Allen wrench or a paper clip through the holes; this sets the idler pulley for zero belt tension. 3. Locate the length of toothed belt that was enclosed with the extension section.
2-8 Pass-Through Mechanism Expansion Kit Installation Instructions 6. Move the left end of the belt to the right and thread it around the idler pulley (Figure 2-5) and back to meet what started out as the right end of the belt. When you hold the two ends of the belt, they should be touching or very slightly overlapping (Figure 2-7).
Upgrade Procedure 2-9 SHR-1239 Figure 2-7. Belt Ends 7. Locate the belt block and the four screws that hold the belt retaining plates to the block (Figure 2-8). Loosen the four screws and slide the ends of the belt under the plates until they engage the teeth on the block; both ends of the belt should be visible through the gap between the plates. Set the belt so there is only a small space between the ends of the belt (about 1/32"). 8. Tighten the four screws that hold the belt retaining plates. 9.
2-10 Pass-Through Mechanism Expansion Kit Installation Instructions 2 1 3 SHR-1240 Belt; Visible gap; Block. Figure 2-8. Belt Block with Belt in Place 10. Open the door of the car and locate the two captive screws. Figure 2-9 shows the screws, (2), and also shows the car in the track, although at the time of this step the car has not yet been installed in the track (the figure also shows the car without the door for clarity; don’t remove the door) 11.
Upgrade Procedure 2-11 2 1 SHR-1198 Figure 2-9. Aligning the Captive Screws with the Belt Block 16. Begin to tighten the captive screws. When both screws are threaded into the belt block partially, release the belt and then continue to tighten the screws until the belt block is seated firmly against the car bracket. Close the car door and secure it. 17. Using nylon button rivets install safety covers over any exposed mechanism sections that will not be covered by modules. 18.
2-12 Pass-Through Mechanism Expansion Kit Installation Instructions understand how to do the steps in this section. To add to an existing mechanism you must first disassemble the mechanism partially, then make the necessary changes using procedures described in the preceding sections. Do the following steps. 1. Locate the support braces on the mechanism (Figures 2-1 and 2-4).
