CAUTION
THIS PROPELLER HAS BEEN
DYNAMICALLY BALANCED.
Location of the Static Balance Weights
May have Been Altered.
B. Inspection Procedures Before Balancing
(1) Visually inspect the propeller assembly before dynamic
balancing.
NOTE: The first run-up of a new or overhauled
propeller assembly may leave a small amount
of grease on the blades.
(a) Use Stoddard solvent (or equivalent) to completely
remove any grease on the blades or inner surface of
the spinner dome.
(b) Visually check each propeller blade assembly for
evidence of grease leakage.
(c) Visually inspect the inner surface of the spinner
dome for evidence of grease leakage.
(2) If there is no evidence of grease leakage, lubricate the
propeller in accordance with the Maintenance Practices
chapter in this manual. If grease leakage is evident,
determine the location of the leak and correct before
relubricating the propeller and dynamic balancing.
(3) Before dynamic balance record the number and location
of all balance weights.
(4) Static balance is required when an overhaul or major
repair is performed at a propeller overhaul facility.
NOTE: If static balancing is not accomplished before
dynamic balancing, the propeller may be so
severely unbalanced that dynamic balance
may not be achievable due to limitations of
measurement equipment.
