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.
