burnished at the factory, but the airgaps
can shift as a result of rough handling during
shipping and installation.
An airgap that is too large can prevent the
armature from engaging. An airgap that is
too small can cause the armature to rub
continuously, causing higher running
temperatures and decreased wear life.
To reset the airgaps, you will need to access
the armatures.
Looking
through the vents on either side of the hous-
ing, you will see the fan on the clutch rotor.
Rotate the fan
(input) until you
see the 1/2 x 1 inch window on the outer
periphery of the fan. Through this window,
you will be looking between the two arma-
tures of the clutch and brake. (Figures 7
& 8)
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 9)
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.
