GENERAL. (PA-28RT-201T)
PROPELLER ASSEMBLY. (HARTZELL)
REMOVAL OF PROPELLER. (Refer to Figure 61-1.)
—WARNING—
Before performing any work on the propeller, be sure the
magneto and master switch is OFF and the mixture control is in
the IDLE CUT-OFF position.
1. Remove the engine cowling. (Refer to Chapter 71.)
2. Remove the safety wire from the propeller mounting nuts and remove the nuts.
3. Place a drip pan under the propeller to catch oil spillage and pull the propeller from the engine shaft.
4. If the spinner and spinner bulkhead are to be removed, remove the spinner attaching screws. The aft
spinner bulkhead may be removed from the hub by removing the locknuts.
CLEANING, INSPECTION AND REPAIR OF PROPELLER.
—NOTE—
Do not attempt to disassemble the propeller any further than
stated in this manual. For internal repairs and replacement of
parts, the propeller should be referred to the Hartzell Factory or
Certified Repair Station.
1. Check for oil and grease leaks.
2. Clean the spinner, propeller hub, and blades with a non-corrosive solvent.
3. Inspect the hub parts for cracks.
4. Steel hub parts should not be permitted to rust. Use aluminum paint to touch up, if necessary, or
replate them during overhaul.
5. Check all visible parts for wear and safety.
6. Check blades to determine whether they turn freely on the hub pilot 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 propeller should be disassembled by an authorized Service Center.
7. Inspect the blades for damage or cracks. Nicks in the 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 61-2 for propeller blade care.)
8. Check the condition of the propeller mounting nuts and studs.
