PROPELLER BALANCING

Thrush Aircraft, Inc. recommends that the
propeller by dynamically balanced to the
engine whenever a new propeller or an
overhauled propeller is installed, or any
time there is a question of the propeller's
balance. Following the instruction of the
propeller balancing equipment (Chadwick
Helmuth Vibrex or equivalent equipment),
set the amplitude of vibration given in IPS
(inches per second) on the balancers
meter to a level of .2 or less at 1,500 rpm

RIGGING AIRFRAME ENGINE
CONTROLS
Engine speed and propeller function is
controlled through
assemblies, belcrank assemblies, cables
and cockpit quadrant levers.
This section will explain the procedures for
rigging the TPE 331-10 engine to the
Turbo Thrush airframe engine controls.
This procedure is presented as a general
guide and variation from this procedure is
permitted. Any available adjustment may
be utilized to achieve engine to cockpit
rigging, provided that no thread witness
holes are ported, that lever travel cushion
exists where required, and engine inputs
move from stop to stop.
* NOTE *
Do not add more than four (4)
balance weights (P/N A-1305) in
any one stack. A maximum total of
eight (8) weights are allowed on any
one clamp half.
