Now take that with a grain of salt (and a big wrench and hammer) and whack
it off of the shaft (uhhhh...that just doesn't sound right for some
reason...but you get the point). :)
You can move the fan and clutch assembly into the fan shroud (on the V6) to
get it out of the way and/or slide it out of the vehicle - no need to remove
the shroud (and this is coming from experience on doing them).

Hi:
Here is what my FSM says for my '98 model.
VISCOUS FAN/DRIVE-3.9L/5.2L/5.9L ENGINES
REMOVAL
(1) Disconnect battery negative cable.
(2) The thermal viscous fan drive/fan blade assembly is attached (threaded)
to water pump hub shaft. Remove fan blade/viscous fan drive assembly from
water pump by turning mounting nut counterclockwise as viewed from front.
Threads on viscous fan drive are RIGHT HAND. A Snap-On 36 MM Fan Wrench
(number SP346 from Snap-On Cummins Diesel Tool Set number 2O17DSP) can be
used. Place a bar or screwdriver between water pump pulley bolts to prevent
pulley from rotating.
(3) Do not attempt to remove fan/viscous fan drive assembly from vehicle at
this time.
(4) Do not unbolt fan blade assembly from viscous fan drive at this time.
(5) Remove fan shroud attaching hardware (two bolts at bottom-two clips at
top).
(6) Remove fan shroud and fan blade/viscous fan drive assembly as a complete
unit from vehicle.
(7) After removing fan blade/viscous fan drive assembly, do not place
viscous fan drive in horizontal position. If stored horizontally, silicone
fluid in the viscous fan drive could drain into its bearing assembly and
contaminate lubricant.
CAUTION: Do not remove water pump pulley-to-water pump bolts. This pulley is
under spring tension.
(8) Remove four bolts securing fan blade assembly to viscous fan drive.
INSTALLATION
(1) Install fan blade assembly to viscous fan drive. Tighten bolts to 23 Nm
(17 ft. lbs.) torque
(2) Position fan shroud and fan blade/viscous fan drive assembly to vehicle
as a complete unit.
(3) Install fan shroud.
(4) Install fan blade/viscous fan drive assembly to water pump shaft and
tighten bolts to 27 Nm (20 ft. Lbs.).
(5) Connect battery negative cable.
