As the tape leader block assembly (LBA) is secured in the cartridge, you
should hear the LBA retention spring clips click into place. If you do not hear
the click, continue rolling until the threader motor worm gear (
4
in
Figure 8-141) stops. The LBA is in the correct position.
Note: Be sure to keep tension on the tape as the LBA is drawn into the
cartridge by using a hex wrench as shown in Figure 8-140 on page
8-130.
8. Notice the:
a. Loader mechanism gear (
6
in Figure 8-141) nearest the front of the drive
that actuates the cartridge loader mechanism.
b. Position of the rotate stub (
3
in Figure 8-141).
c. Front loader motor worm gear (
1
in Figure 8-141). Rotating this gear
allows the loader mechanism gear (
8
in Figure 8-141) to turn.
9.
Rotate the loader motor worm gear (
1
in Figure 8-141) to turn the threader
mechanism gear (
6
in Figure 8-141) counterclockwise. Continue turning until
the rotator stub (
3
in Figure 8-141) loses contact with the lever (
7
in
Figure 8-141). This releases the LBA leader pin.
