18-13 Track Adjustment (continued)

B. Main Rotor Blade Trim Tab (continued)

2. Position MT352-1 gage chordwise across blade upper surface and tab trailing edge.

Zero dial indicator on measuring point.

3. Position MT526-8 bending tool on tab per Figure 18-4. Slide tool completely over

tab until tool stops contact blade trailing edge. Double-rib side of tool should contact

tab upper surface to bend tab down. Double-rib side of tool should contact tab

bottom surface to bend tab up.

4. Tighten MT526-8 bending tool bolt to bend tab. Make slight bends and remeasure tab

with MT352-1 gage. Bend trim tab 0.015 inch (down) to effect dynamic movement

of main rotor blade tip approximately 0.2 inch (downward).

18-14 Balance Adjustment

WARNING

A rotor which is smooth after balancing but goes out of balance

within a few flights is suspect and must be examined by RHC

before further flight.

A. Tip Weights (Spanwise Balance Adjustment)

1. Remove screws securing tip cover to blade. Balance rotor assembly spanwise

by adjusting tip weights as required per Figure 18-2. Washers may be trimmed.

Special torque fasteners securing tip weights per Section 20-33. Install tip cover

and standard torque fasteners per Section 20-32.

B. Teeter Hinge Bolt Shims (Chordwise Balance Adjustment - Coarse Adjustment)

1. Remove and discard teeter hinge nut cotter pin. Remove nut, thrust washer, and any

shims.

2. Have two people cone the main rotor blades. Push out teeter hinge bolt (and any

shims) with another bolt.

3. Balance rotor assembly chordwise by moving (or exchanging) existing teeter hinge

shims to other side of bolt (under head or under nut) as required per Figure 18-2.

Install teeter hinge bolt per Section 62-10.

C. Chord Arm Weight (Chordwise Balance Adjustment - Fine Adjustment)

1. Balance rotor assembly chordwise by adjusting chord arm weights or washers per

Figure 18-2. Total weight not to exceed four A255-2 weights (or equivalent).

(1) A255-1 Weight

(8) AN970-4 Washers

(1) A255-2 Weight

(3) A255-1 Weights

18-15 Troubleshooting

The following are some of the symptoms and corrections which occur in the Track and Balance
