AND 6, AEROSHELL GREASE 5 MUST BE
INDICATED ON THE LABEL (HARTZELL
PROPELLER INC. P/N A-3594) AND THE
AIRCRAFT MUST BE PLACARDED TO
INDICATE THAT FLIGHT IS PROHIBITED IF

APPROVED GREASE ONLY. EXCEPT IN
THE CASE OF AEROSHELL GREASES
5 AND 6, DO NOT MIX DIFFERENT
SPECIFICATIONS AND/OR BRANDS OF

these two greases is acceptable in Hartzell Propeller Inc.
propellers.

applied to the propeller to indicate the type of grease
previously used. Refer to Figure 6-3.
(a) This grease type should be used during
re-lubrication unless the propeller has been
disassembled and the old grease removed.
(b) It is not possible to purge old grease through
lubrication fittings
.
(c) To completely replace one grease with another, the
propeller must be disassembled in accordance with
the applicable overhaul manual.
