CLUTCH SPRING OR HUB BRAKE
The clutch spring or hub brake should completely release when the
pressure
roller is in the vertical position. This allows the hub,
and the tape, to move freely. An improperly adjusted clutch spring
or defective
hub brake may prevent the roller from engaging or dis-
engaging. The clutch should be parallel to the bottom of the shell
and no more than 0.1875 inch above the surface of the tape deck.
The clutch must not protrude more than 0.125 inch into the opening
for the pressure
roller. Less than 8 ounces should be required to
release the clutch.

The pressure pads must wrap the tape around the face of the heads.
The pressure applied must be uniform across the tape as it is in
contact with the head.
Periodically check the pads to see that they
are
lined up squarely with the tape. If one portion of the tape
is not in contact with the pads, that portion of the tape will make
poor contact with the head. This may show up as poor frequency
response
from an individual cartridge.
