Testing

1. Starter Sealing Test Setup.

a. Remove one brush inspection plug and gasket from starter frame.

b. Install leak test fitting and gaskets in opened hole.

Install pressure gage in chamber and shutoff valve at chamber in let.

WARNING

Compressed air used for cleaning purposes will not exceed 30 psi. Use only with effective

chip guarding and personal protective equipment (goggles/ shield, gloves, etc.).

d. Attach hose from dry compressed air supply adjusted for 6 psi to starter leak test setup.

2. Alternate 1 Test Procedure.

CAUTION

Do not wet drive end housing or drive clutch assembly.

a. Using jib boom, lower starter into a tank of clean soap and water until only drive end housing is exposed

above water surface.

b. Visually check for air bubbles. Bubbles show location of leaks, which must be corrected.

3. Alternate 2 Test Procedure.

a. Close air valve to trap pressure inside starter and observe pressure gage for three minutes. Pressure

decrease exceeding 0.5 psi/minute indicates an unacceptable leak.

b. Restore pressure as necessary, and apply soap and water solution to external bolts, screws, and gaskets to

find location of leak. Soap bubbles will form over location of leak which must be corrected.
