RE-ESTABLISHING PROPER BOOSTER / HORN

INTERFACES

To re-establish proper interfaces, follow these instructions:

1. Using open-ended wrenches, separate the booster from the horn. Clean

each item and then examine interfaces for irregularities (scoring).

2. If irregularities are present, remove the stud.

3. Tape a sheet of 400 grit emery cloth to a smooth, flat surface. (Do not use

coarser than 400 grit.)

4. Grasp the lower portion of the booster or horn and move it across the

emery cloth. To ensure proper lapping, a) hold the part straight, b) apply

light downward pressure, and c) move in one direction only in a figure 8

pattern.

Repeat the figure 8 pattern once more.

5. Then, rotate the booster or horn 1/3 of a turn in a clockwise direction and

then repeat step 4.

6. Repeat step 5.

7. Using wire brush, clean stud, then replace securely. Tighten new stud to

the recommended torque specifications on page 12.

NOTE: Contact between

the booster and horn

should be parallel. When

encountering symptoms

such as loud noises or

tuning difficulties, examine

the booster / horn

interfaces for parallelism,

corrosion, galling or foreign

deposits. Also check the

tightness of the stud.

DO NOT use anything

coarser than 400 grit

emery cloth.

NOTE: Machining of

booster / horn may alter

the ability to tune the

component to the system.

System inoperation may

occur.
