The disassembly of the tender starts by carefully inverting the tender and allowing it to rest on a towel or other type of cushioned work surface. Next, using the small nut-driver that comes with the K-28, remove the miniature bolts holding the braking mechanism as pictured below.
The brake mechanism and its bolts are set aside. The 6 small bolts that hold the tender's upper and lower halves together are located and removed. The picture below shows the location of the 6 bolts; there are 3 on each side.
With the removal of the 6 bolts marked above, it is now possible to separate (somewhat) the upper and lower halves of the tender. As the sections are being separated, the two silver "L" channel trim strips are removed completely and set aside. The upper and lower tender sections are still connected to each other by the light wiring. The picture below shows the upper and lower sections detached from each other, the light wiring connections, and the two silver "L" channel trim strips.
Turning the lower tender section upright, you can easily view the electrical circuitry of the tender's interior. Now, the remove the tender's pneumatic brake reservoir by extracting the two bolts shown in the photo below does this action. The reservoir is set aside with the brake mechanism that was removed in an earlier step.
The photo below shows a close examination of the stock wiring points of the LGB tender. The two sets of lighting leads are disconnected and the upper and lower halves of the tender are now 100% separate. Note that the track power leads are left connected as originally installed.
The following photo shows the completely separated halves. With the lower section free it is time to start thinking of how the sound system is going to be installed.
Please note that the procedure for putting the tender back together is simply to follow this section's operations in reverse order starting from here and working backwards (up instead of down). Overall the tenders disassembly was quick and simple with no surprises.
