Installing the PTM26
6. Turn the PTM base unit over and then remove the drive belt from the media elevator car, the belt
tensioner ramp, and the idler pulley (see Figure 5 on page 16).
7. Discard the belt.
8. Remove the belt tensioner ramp and idler pulley components as follows (see Figure 16 on
page 26):
a. Remove the two screws and springs from the belt tensioner ramp and idler pulley.
b. Remove the two screws that secure the belt tensioner ramp and idler pulley to the PTM base
unit.
c. Remove the belt tensioner ramp and idler pulley.
NOTE: Retain the belt tensioner ramp/idler pulley springs and associated hardware for use in the
subsequent installation steps. To avoid misplacing this hardware you can use step 12 and step 13
to install it on the last extension at this time, if desired.

a. Insert the alignment pins of the extension into the corresponding slots at the bottom of the
PTM base unit.
b. Align the pins of the two narrow tie bars with the holes in the extension and PTM base unit
(see Figure 18) and then attach them using four mounting screws (two screws for each
narrow tie bar).
