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 .
(Figure 7)
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 armature
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.
