This is a three step process.
1. Simply slide the screwdriver through the
window. By twisting the screwdriver, it works
as a wedge to apply pressure on the back of
the armature pushing it toward its mating
friction surface.
2. Rotate the output of the unit. The rotor and
window should stay in place when you do
this. Only the armatures will move. If you
rotate the input of the unit, the rotor and
access window will rotate as well.
3. Alternately repeat steps 1 & 2 to ensure that
the airgap between the armature and its
mating surface is about 1/32 inch and the
armature remains square to its mating
surface. (If the armature is uneven, it may
engage on just one side giving the
appearance of engagement but failing to
provide full torque.)
If there is a scraping or rubbing sound when the
output shaft is rotated, this means that an arma-
ture is dragging and is too close to its mating
surface. Simply repeat steps 1-3 above, but
place the screwdriver between the face of the
armature and its mating friction surface and
move the armature away from its friction mating
surface.
Note: If you have a (20FBB, or FBC) Fail Safe
Brake Module the airgap is set at the factory and
should not need adjusting. The brake setup will
be covered during the FB Brake Release
Adjustment Section J.
If the armature for either the clutch or the brake is
too far away from its mating friction surface, it is
possible to move it back into adjustment using a
flat blade screwdriver between the two armatures.
