(d) The spinner dome, spinner bulkhead, and the hub
clamping bolts must not interfere with, or bind with,
anti-ice or de-ice hardware, if installed.
(e) If a spinner forward bulkhead is installed and is
bonded to the spinner dome, make sure that the
inward facing flange that pilots on the propeller
cylinder does not interfere with a corner on the
propeller cylinder. Refer to Figure 3-4.
(2) Additional washers/spacers may have been installed on
the hub clamping bolts from the factory to help with the
installation of a reusable self-locking nut on the threaded
part of each hub clamping bolt.
(a) The additional washer(s)/spacer(s) must be removed
before spinner installation.
(3) Install a washer or washers in Area 2 on the hub
clamping bolts if required, to make sure of clearance as
listed in paragraphs 3.B(1)(a) through 3.B(1)(e). Refer to
Figure 3-3.
(4) Install a spacer or spacers, if required, on each hub
clamping bolt between the bulkhead and hub or
bulkhead and washer(s).
CAUTION:
(5) Install the spinner bulkhead over the hub clamping bolt
locations as shown in Figure 3-2. The spinner bulkhead
will be supported by some combination of spacer(s) or
washer(s).
(a) The spinner bulkhead must touch spacers(s) or
washer(s), not the hub.
NOTE:
(6) Install at least one flat washer "F" in Area 1 on the hub
camping bolts over the spinner bulkhead. Refer to
Figure 3-3 and Table 3-2.
