2 Change the location of the spinner dome
mounting holes and forward bulkhead unit by
installing or removing spacers that are between
the cylinder and forward bulkhead. Refer to
Figure 3-15.
(b) Optionally, for a spinner dome that has a removeable
forward bulkhead, apply a layer of flourglas tape or
UHMW tape (Hartzell Propeller Inc. P/N B-6654-100)
on the outboard flange of the forward bulkhead to
prevent contact between the forward bulkhead and
the spinner dome.
1 Using acetone, denatured alcohol, or MEK,
clean the area where the tape will be applied.
2 Cut eight pieces of tape that are approximately
three inches (76 mm) long.
3 Apply the pieces of tape in equally spaced
locations on the forward bulkhead as shown in
Figure 3-16.
4 Tape may be wrapped over trailing edge of the
forward bulkhead as necessary.
(3) For the HC-E5A-2 propeller apply one or more layers
of fluoroglas or UHMW tape (Hartzell Propeller Inc.
P/N B-6654-100) to the forward bulkhead where the
bulkhead touches the cylinder.
(a) Apply a layer of tape, examine, and repeat until the
forward bulkhead unit fits snugly on the cylinder.
(4) For the HC-E4P-5( ) propeller with spinner assembly
D-5362:
(a) Verify that the hoop unit is installed on the spinner
bulkhead and installed on the propeller.
