    a. If the service safety door is present, and you wish to replace the left elevator motor, ask the operator to place the left elevator offline to StorageTek Library Console (see “Service Safety Door Verification” on page 286 if you are unfamiliar with activation of the service safety door).
    b. If the service safety door is present, and you wish to replace the right elevator motor, ask the operator to place the right elevator offline to StorageTek Library Console and place the CAPs offline to the Host/ACSLS.

2. Open the appropriate library front door (see the note “Opening Access Doors” on page 39).
3. Disconnect the motor assembly power cable (1) shown in FIGURE 1-56 on page 76 at the bulkhead connector.
4. Loosen the T15 tension assembly screw (2) shown in FIGURE 1-56 on page 76, press on the tensioner to relieve tension, then re-tighten the screw.
5. Remove two T15 screws (3) shown in FIGURE 1-56 on page 76, on opposite corners of the mounting plate.

6. Rotate motor assembly toward tensioner to disengage drive belt.
7. Lift the motor assembly away from the mounting area.
