posite side of wheels (Item 1). LOCK RATCH-
ET JACK HANDLE(S) (Item 2) into position

7. Loosen outer bearing from its mounting as
shown in Photo DCP0659 on page 31. Un-
less this bearing is also being serviced, it is
not necessary to remove it from the rotor at
this time.
8. Remove center anti-wrap shields. This allows
access, through the rotor’s inner end notches
to bearing’s inner race Allen set screws. De-
tach shield and lube tube.
9. Loosen (2) 3/8” Allen set screws (Item 1) from
center bearing (Item 2). These are retained
with anaerobic threadlock (eg. Locktite 242
(blue) or Perma-lok HM 118 (red). See Photo
DCP0591.

Commercial anaerobic threadlocks have instal-
lation instructions, and SAFETY CAUTIONS, on
their containers. These should be adhered to.
10. Attach chain sling around rotor. Outer end
of rotor is lifted above frame to obtain clear-
ance.
Axially pry rotor free of its inner bearing and
swing it clear of working area.
NOTE:
Care-
fully lift both split rotors together on units with
four rotors. Sling should be from center of ro-
tors to reduce stress on coupling.
