For One Piece Rear Spinner Bulkhead Installation:
Step 2: Note the factory position of the spinner rear bulkhead in the
spinner dome in relation to the blade cutouts to determine its
required position on the propeller hub. The spinner and spinner rear
bulkhead have been number coordinated to match the blade cutout
openings. Using the supplied AN3 bolts and nuts install the spinner
rear bulkhead to the spinner mounting plates. The supplied flat
washers are to be installed on the fiberglass side. The bulkhead is
to be installed on the aft side of the mounting plates. (The standard
200C 14” rear bulkhead is an exception; it is to be installed on the
forward side of the mounting plates. A slot is provided in the
bulkhead so it can be slipped over the mounting plates into its
forward position.) Tighten the bulkhead mounting hardware.
Step 3: If used, lightly lubricate the O-Ring with clean oil or O-Ring
lube and carefully install the propeller on the engine crankshaft by
tightening the (6) propeller bolts.
Warning: To avoid severe damage to the hub, when tightening
the propeller bolts insure that the face of the prop hub is kept
parallel with the face of the flywheel. In most cases this will
require tightening the propeller bolts a little at a time in an
alternating pattern.
Step 4: Torque and safety wire the propeller hub bolts. Refer to data
sheet for torque (dry, non-lubricated) values (65 ft-lbs for ½”
hardware or 47 ft-lbs for 7/16” hardware). Safety wire the prop bolts
in pairs with 0.32” stainless safety wire after installation.
** Installation with a one piece rear bulkhead is complete. Proceed to
Section 4.2 **
For Two Piece Rear Bulkhead Installation:
Step 5: Remove the (2) spinner installation plates. Save them for
future use.
Step 6: Note the factory position of the spinner rear bulkhead in the
spinner dome in relation to the blade cutouts to determine its
required position on the propeller hub. The spinner and spinner rear
bulkhead have been number coordinated to match the blade cutout
openings. Using the supplied AN3 bolts and nuts install the spinner
rear bulkhead to the spinner mounting plates. The supplied flat
washers are to be installed on the fiberglass side. The bulkhead is
to be installed on the aft side of the mounting plates. Tighten the
bulkhead mounting hardware.

4.2 Spinner Dome Installation
Install the spinner dome onto the propeller hub and rear
bulkhead. The spinner and spinner rear bulkhead have been
number coordinated to match the blade cutout openings.
The spinner dome has a forward bulkhead with a flanged hole
that must engage the cylinder (cap) on the front of the
propeller hub. The fit of the forward bulkhead to the cylinder is
to be snug BUT NOT SO TIGHT that excessive force is
required to push it on. If the fit is too tight, sand the inside of
the forward bulkhead flange. If the fit is too loose, apply the
provided Teflon tape to the cylinder. In some cases a
combination of these processes will be required to obtain the
proper fit.
Fasten the spinner dome and blade cutouts to the rear
bulkhead using the supplied screws and nylon washers.
IMPORTANT: Periodically verify that the spinner screws
are tight during the first few hours of operation.
