Propeller Models Covered by This Steel Hub Turbine Propeller Maintenance Manual

This 118F manual applies to Hartzell three-blade and four-blade steel hub turbine propeller assemblies, including the following model families:

• Three blade: HC-A3VF-7( ), HC-A3MVF-7( ), HC-B3MN-3( ), HC-B3MN-5( ), HC-B3TN-2( ), HC-B3TN-3( ), HC-B3TW-3( ), HC-B3TN-5( ), HC-B3TF-7( )
• Four blade: HC-B4MP-3( ), HC-B4TN-3( ), HC-B4TW-3, HC-B4MN-5( ), HC-B4TN-5( )

Because Hartzell’s steel hub propeller line spans these numerous variant suffixes rather than a single fixed part number, this manual’s coverage is broad by design, and a technician working any of the listed HC-A3, HC-B3, or HC-B4 configurations will find the applicable procedures inside.

Taken as a whole, the 118F Steel Hub Turbine Propeller Maintenance Manual gives a technician the full lifecycle picture for these steel hub assemblies: how the constant-speed mechanism operates, how to tear the unit down, how to inspect components against airworthy-damage limits, how to execute approved field and major repairs, and how to rebuild and torque the assembly back to specification.

Description and Operation

The manual explains that Hartzell steel hub propellers use a steel component as the central hub, with blades and bearing assemblies mounted on hub arms and secured by two-piece steel clamps. A threaded steel cylinder and aluminum piston, connected to the clamps by link arms, control blade angle, with counterweights, a feathering spring, or both used depending on model. Three operating configurations are detailed: constant speed non-feathering with counterweights (-1 models), constant speed feathering, and constant speed feathering and reversing (-3, -5, and -7 models), including the beta feedback linkage differences between the -3 models (external collar and carbon block) and the -5/-7 models (concentric beta tube).

Testing, Disassembly, Cleaning, and Check

A Troubleshooting Guide in the Testing and Fault Isolation chapter walks through symptom-based fault diagnosis, such as grease leakage at the blade clamp, tracing probable causes back to torque values, seal gaskets, or O-ring condition. The Disassembly, Cleaning, and Check chapters that follow set out the teardown sequence and the airworthy-damage inspection criteria a technician uses to determine whether a component may return to service, be repaired, or must be replaced.

Repair and Assembly Procedures

The Repair chapter covers field-level corrections such as start lock pin and start lock plate adjustment, including the exact start lock pin dimensions and tolerance (±0.010 inch) shown in the manual’s figures. The Assembly chapter is the most extensive section of the 118F Steel Hub Turbine Propeller Maintenance Manual, detailing cylinder and guide collar installation with hydraulic sealant application, spinner support plate mounting with fixture-specific procedures for three- and four-blade units, beta ring installation with a 0.010-inch (0.25 mm) maximum runout tolerance, start lock installation and start pitch blade angle measurement (0.2-degree blade-to-blade tolerance), and final reassembly of the beta system.

Fits and Clearances – Torque Values

The Fits and Clearances chapter is the reference point cited throughout the Repair and Assembly chapters and contains four tables: spring identification (Table 8-1), Torque Values (Table 8-2) listing specific ft-lb, in-lb, and N·m torque figures by item number and part number for nuts, screws, bolts, and the propeller cylinder itself, Blade Torque Values (Table 8-3) for aluminum and composite blades mounted in the blade clamp, and Blade Tolerances (Table 8-4). This chapter is what a technician returns to repeatedly while working through the Assembly chapter to torque fasteners correctly the first time.

Why This Hartzell 118F Steel Hub Turbine Propeller Maintenance Manual Matters

Working to the correct revision of a propeller maintenance manual is not optional in this field: incorrect torque values, missed airworthy-damage limits, or outdated repair criteria can directly affect flight safety, and the manual itself carries an explicit warning to that effect. This 118F Steel Hub Turbine Propeller Maintenance Manual gives you the FAA-reviewed procedures, torque specifications, and inspection criteria needed to disassemble, inspect, repair, and reassemble Hartzell HC-A3, HC-B3, and HC-B4 steel hub turbine propeller assemblies correctly and to specification.
