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 and inner surface of
the spinner dome.
(a) Use Stoddard solvent (or equivalent) to completely
remove any grease on the blades or inner surface of
the spinner dome.
(b) Visually examine each propeller blade assembly for
evidence of grease leakage.
(c) Visually examine 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
re-lubricating the propeller and dynamic balancing.
(3) Before dynamic balance, record the number and location
of all balance weights.
(4) Static balance is accomplished at a propeller overhaul
facility when an overhaul or major repair is performed.
NOTE: If static balancing is not accomplished before
dynamic balancing, the propeller may be so
severely unbalanced that dynamic balance
may not be possible because of measurement
equipment limitations.
