(1) Spinner installation must make sure of clearance in the
following areas:
(a) The spinner bulkhead must be spaced between the
hub and the engine cowl to permit the spinner dome
blade cut-out openings to clear the propeller blades
at all blade angle locations. Refer to Figure 3-4.

The spinner bulkhead and any attached filler
plate must also clear the propeller blades at all
blade angle locations. Refer to Figure 3-4.
(b) The edge of the spinner bulkhead and the installed
spinner dome that faces the engine cowl must
have space to clear the engine cowl and avoid
interference during propeller/engine operation.
Refer to Figure 3-4.
(c) The hub clamping bolts on which the spinner
bulkhead is attached must not be so long that the
bolts interfere with the engine cowl during
propeller/engine operation. Refer to Figure 3-4.

install spacer(s)/washer(s) between the head of
each hub clamping bolt to move the threaded
end of the bolt away from the engine cowl.
Refer to Figure 3-4.
