Note

Indicator rod may retract during cold temperatures or extend during high temperatures. Inspect and service when recoil mechanism and damper fluid are at room temperature, approximately 77°F (25°C).

1. INSPECT REMOVED RECOIL MECHANISM.

a. Check outside of recoil damper rod (1), indicator rod (2) and recoil housing cap (3) for evidence of damper fluid leakage. If there is evidence of leakage or maintenance records show that recoil mechanism has required servicing at least two times in the past four weeks, send recoil mechanism to Direct Support Maintenance for seal replacement. Proceed to step 2.

b. Examine recoil damper rod (1) and indicator rod (2) for bent, scratched, scored, cracked, or grooved diameters. Check for cracks around pin holes. If any of these conditions are found, send recoil mechanism to Direct Support Maintenance for repair. Proceed to step 2.

c. Inspect recoil housing cap (3) and nut (4) for cracked, stripped, or damaged threads. Inspect headed straight pin (5) for cracks and bends. If any of these conditions are found, replace defective part.

d. Inspect stacked springs (6) for cracks and galling. If either of these conditions are found, send recoil mechanism to Direct Support Maintenance for repair. Proceed to step 2.
