Loosen the lock collar by unscrewing
and removing the set screw with an
1/8” Allen wrench. Insert a pin
punch and tap at an angle with a ball
peen hammer, turning the collar
clockwise until you can remove it.
(Before reassembling the collar, use
sand paper to smooth the burr where
the set screw enters the hub. Be sure
the collar mounts flush with the out-
side of the rotor bearing shaft.)
4
Remove the flange nuts from around
the perimeter of the fan housing.
Next, loosen but do not remove the
three flange nuts holding the triangu-
lar flangettes over the bearing. Pull
apart the housings, then take off the
flangettes and remove the entire fan
housing. Position it underneath the
unit, as seen in the next drawing...
5
Note how the fan housing has been
placed underneath. Put a rag there,
too, to avoid scratching the housing.
Use a 9/16” wrench to remove the
3/8” bolt from the center of the rotor
shaft. (When reassembling, use a
torque wrench to tighten this bolt to
45 ft.-lbs.)
6
Pull the rotor from the crankshaft by
turning the rotor back and forth.
There may be some resistance. Pull it
off steadily, making sure that the
hammers clear the inner wall of the
center plate. (When reassembling,
coat the exposed engine shaft and
key with a liquid graphite or slip
plate type compound.)
THE VACUUM
