Page 3-12Rev. 1 Dec/1461-10-73FINISH PROCEDURES

I. Erosion Mask Installation

NOTE: For the finish procedures applicable to each spinner assembly, refer to Table 3-1 Finish Procedures in this chapter.

(1) Inspect for missing paint, pin holes, pitting, and porosity as follows:

(a) Visually examine the dome erosion shield forward of the dome erosion shield parting line.

(b) Visually examine the spinner dome aft of the dome erosion shield parting line.

(c) Repair any defect in accordance with the section "Dome Erosion Shield Repair" in the Minor Repair chapter of this manual.

(2) Inspect the spinner dome aft of the dome erosion shield parting line.

(3) Inspect the spinner dome aft of the dome erosion shield parting line.

(4) If the dome erosion shield and spinner dome do not require repairs, continue with the steps in the following Installation Procedure.

(5) Cleaning

WARNING: ADHESIVES AND SOLVENTS ARE FLAMMABLE AND TOXIC TO THE SKIN, EYES, AND RESPIRATORY TRACT. SKIN AND EYE PROTECTION ARE REQUIRED. AVOID PROLONGED CONTACT AND BREATHING OF VAPORS. USE SOLVENT RESISTANT GLOVES TO MINIMIZE SKIN CONTACT AND WEAR SAFETY GLASSES FOR EYE PROTECTION. USE IN A WELL VENTILATED AREA AWAY FROM SPARKS AND FLAME. READ AND OBSERVE ALL WARNING LABELS.

(a) Using cheesecloth CM159 or equivalent dampened with solvent acetone CM173, MEK CM106, or MPK CM219, wipe the surface clean where the UHMW tape CM137 will be installed on the forward bulkhead of the dome.

(6) Installation Procedure

CAUTION 1: DO NOT TRIM THE EROSION MASK ON THE SPINNER DOME BECAUSE DAMAGE TO THE SPINNER DOME WILL OCCUR.

CAUTION 2: DO NOT INSTALL THE EROSION MASK ON THE DOME EROSION SHIELD UNTIL THE PAINT HAS CURED FOR A MINIMUM OF EIGHT (8) HOURS OR THE EROSION MASK WILL NOT ADHERE PROPERLY.

(a) Refer to Table 3-1 Finish Procedures in this chapter, for approval for installation of the erosion mask.

(c) Except for trimming the erosion mask when installed on the spinner, follow the manufacturer's instructions for making a template and trimming the customer procured erosion mask.

1 Using a measurement of 5.0 inches (127.0 mm) along the surface of the erosion mask, from the top centerline down the side of the erosion mask produces a mask of satisfactory size.

(d) Install the erosion mask to the dome erosion shield in accordance with manufacturer's installation instructions.

1 The erosion mask must be smooth over the dome erosion shield and the spinner dome with no air pockets.

J. Resistance Check of the Dome

NOTE 1: For the finish procedures applicable to each spinner assembly, refer to Table 3-1 Finish Procedures in this chapter.

NOTE 2: The dome is not installed on the bulkhead or the adapter ring unit.

(1) Install a screw with washers and a nut in each of two dome mounting holes with the maximum distance possible between them, in accordance with the information in Figure 3-1.

(2) Using an ohm meter capable of 20 Megohms, perform the following resistance checks:

(a) Measure the resistance from the screw in one dome mounting hole to the screw in the other dome mounting hole. Refer to Figure 3-1.

1 If the resistance measurement is not satisfactory, clean the contact points using a solvent such as CM23 or equivalent and repeat the resistance measurement.

2 If the resistance measurement is not satisfactory after cleaning for the two holes, use two different holes with the maximum distance possible between them and repeat the measurement.

a Repeat the measurement using different holes with the maximum distance possible between them until the resistance measurement is satisfactory.
