Section B: Bolting Two Modules Together
(20-30, 20FBC-30, 30-40)
The brake module (20 or 20FBC) or output clutch
module (40) may be assembled to the input clutch
module (30) .
1 . Align the pilot and mounting holes of brake
module (20 or 20FB) or if clutch only the module
(40) to the pilot and mounting holes of the
clutch module (30) . The wire orientation should
match . Secure the modules together with four
(4) tie-bolts provided . Tighten the four (4) bolts
alternately to ensure even alignment of the
modules . Tighten them to 30-35 foot pounds .
(Figure 4)
Section C: Adjusting the Airgap
For new installations it is necessary to adjust the
airgap between the friction faces of the clutch and/or
brake .

To set the airgap for an Electro-Module (EM) you
will need to access the armatures . You will note
that there are gaps between the housing fins on
both sides of the module . When looking through
this gap, you will see the fan on the clutch rotor . On
the outer periphery of the fan there is a 1/2 x 1 inch
window . It is possible to look inside the module and
see the armatures by looking through this window .
When looking into the window you will be looking
between the two armatures of the clutch or brake .
[In a module (10-40) there is only a single armature .]
