5. Fan Clutches for GMC installations include a Pilot Adapter
pc. no. 292309 (see Fig. 14B). This Adapter is a press fit on
(Cont'd)
either the hub of the Fan Clutch or a spacer and must be
pressed on.
After installing the Fan, the complete pulley-fan assembly
must rotate freely. It is not mandatory that the fan be
located in exactly the same position as the original fan,
as long as it has adequate clearance as shown on Fig.
15 ("A" and "B") and has the same general relationship
to the shroud, if there is one.
FD-1 Fan Clutch must have clearance to rotate freely as the
lining wears and the pressure plate fan assembly moves
towards engine an additional 5/16". It should also be noted
that the fan will move 3/32" toward radiator when clutch is
disengaged.
The fan mounting cap screws must not have a thread
engagement of more than 5/8". They must be Grade 8, all
the same length and torqued to 300-350 in. lbs.
(25-29 ft. lbs.).
6. Tighten the belts and secure the mounting bolts. With no air
pressure on the control port, it should now be impossible to
rotate the fan. If shop air is conveniently available, the
declutch function may now be checked by applying 80 psi
minimum and the fan and fan clutch pressure plate should
rotate freely.
