C. For Propeller Model HC-E5A-2, Measuring the Resistances
(1) Using an ohm meter capable of accurately measuring
the required resistance in accordance with Table 3-4,
measure the resistance from the hub clamping bolt to a
spinner dome mounting nutplate on the bulkhead. Refer
to Figure 3-14.
(2) Before installation of the dome unit, measure the
resistance of the dome unit in accordance with
the section, “Resistance Check of the Dome” in the
Finish Procedures chapter of Hartzell Propeller Inc.
Composite Spinner Maintenance Manual 148 (61-16-48)
that is available on the Hartzell Propeller Inc. website at
www.hartzellprop.com.
NOTE: The dome is not installed on the bulkhead.
D. Installing the Spinner Dome
(1) The spinner dome is supported by a forward bulkhead
unit that encircles the propeller cylinder. Refer to
Figure 3-12.
(2) For propellers in this manual other than the HC-E5A-2
and HC-E4P-5, if the forward bulkhead unit does not
fit snugly on the cylinder, the cylinder may need to be
wrapped with one or more layers of fluoroglas or UHMW
tape (Hartzell Propeller Inc. P/N B-6654-100).
(a) Apply a layer of tape, examine, and repeat until the
forward bulkhead unit fits snugly on the cylinder.
1 Using spacers, move the forward bulkhead unit
away from the cylinder to cause the spinner
dome mounting holes to stop short of full
alignment with the bulkhead holes by 25% of
the spinner dome mounting hole diameter.
Refer to Figure 3-15.
