1. Description of Propeller and Systems
Hartzell steel hub propellers covered in this manual are constant
speed assemblies that use a steel hub as a central component
(Figure 2-1).
The propeller attaches to the engine through either a splined
shaft or one of several flanged designs. On models covered
in this manual, the spline shaft attachment uses a Society of
Automotive Engineers (SAE) Number 20 spline (Figure 2-2).
NOTE
: SAE Number 20 spline shaft propellers are identified
simply as "20 spline shaft" propellers throughout the
text of this manual.
A flanged shaft attachment uses a six bolt and two dowel pin
interface or a six bolt and four bushing interface between the
engine and the propeller flange (Figure 2-3).
