Through this window, you will be looking between
the two armatures of the clutch and brake. (Figures 6
& 7)
If either armature is too far away from its mating
friction suface, it is possible to move it back into
adjustment using a flat blade screwdriver. (Figure 8)
Note:
When resetting the clutch or FB brake
armature airgap, both the clutch and brake must be
released (the brake energized, and the clutch not
energized).
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.
3. Alternately repeat steps 1 & 2 to ensure that
the airgap between the armature and its mating
surface is about 1/32 inch and that 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.
