The FD-1 Fan Clutch should not be used in installations where the fan
blade is larger than 32" in diameter, weighs more than 30 lbs. and
requires more than 22 h.p.
The installation of a Fan Clutch involves two operations: The installation
of the Fan Clutch on the engine and installation and connecting of
the Control System. Both installation operations are explained in the
following text.
After installation of your Bendix Style Fan Clutch, record the Fan Clutch
Serial No., Service Part No., Date of Installation and Vehicle Mileage

FAN CLUTCH INSTALLATION
1.
Drain radiator coolant, note existing clearance between fan
blades and radiator and fan blades and belts (as shown at "A"
and "B" on Fig. 15).
2.
Remove the fan from existing hub.
3.
Remove the existing hub.
4.
Install Fan Clutch. It is advisable to anticipate the fitting to be
used for the air connection and install it before installing the fan.
Where cap screws in some cases are difficult to get started in
the bracket in back of the pulley, prelocate the cap screws in the
slots with string or rubber bands.
Prior to installing vehicle fan, inspect and replace if cracked or damaged.
5.
Install the Belts, but before tightening, install the Fan on the hub.
A Spacer or Spacers may or may not be required to approximate
the original clearance as checked in Step 1. Spacers are available
(1/2" pc. no. 292310 and 292312, 3/4" pc. no. 292311 and
292313) if required; however, maximum spacer thickness should
not exceed 1-1/2". If it is necessary to use the spacer which had
been used with the original fan installation, the center bore must
be a minimum of 1.77". This dimension is important to insure
adequate clearance around the center hub which does not rotate.
It is also extremely important that the spacer be piloted on the
hub and provide a pilot for the fan.
