D. Steel hub parts should not be permitted to rust. Use aluminum paint to touch up if necessary, or
replate during overhaul.
E. Check all visible parts for wear and safety.
F. Check blades to determine whether they turn freely on the hub pivot tube. This can be done by
rocking the blades back and forth through the slight freedom allowed by the pitch change
mechanism. If they appear tight and are properly lubricated, the pitch change mechanism should be
removed so that each blade can be checked individually. If blades are tight, the propeller should be
disassembled.
G. Inspect blades for damage or cracks. Nicks in leading edges of blades should be filed out and all
edges rounded, as cracks sometimes start from such places. Use fine emery cloth for
finishing. Refer to Figure 1 for propeller blade care.
3. Installation
A. Insure master and magneto switches are off.
B. Place fuel selector to off position.
C. Place mixture control in idle cut-off.
D. Observe the starter ring gear to make sure it is mounted properly on the engine crankshaft flange.
One of the bushings on the crankshaft is stamped with an “O” mark and it must be inserted in the
starter ring gear hole, likewise identified with an “O” mark.
E. Wipe crankshaft and propeller pilot to assure that no chips or foreign matter enter the
propeller mechanism.
F. Check interior of propeller hub for proper seating of “O” ring. Wipe inside of hub to remove any
traces of dirt. Check to see that “O” ring is covered with grease.
G. Install rear spinner bulkhead.
H. Slide propeller carefully over pilot, taking care that “O” ring is not damaged.
I. Install the six hexagon head propeller hub mounting bolts and torque per Chart 1.
J. Check propeller blade track as given in Blade Track.
K. Safety the propeller mounting bolts with MS20995-C41 safety wire.
L. Grease blade hub through zerk fittings. Remove one of the two fittings for each propeller blade,
alternate the next time. Apply grease through the zerk fitting until fresh grease appears at the fitting
hole of the removed fitting. Care should be taken to avoid blowing out hub gaskets.
M. Install spinner. Torque all attachment screws per Chart 1.
