WP 0020 00-7, Item 3:
Under procedures, add "Check buffer housing for peening, cracking or damage to include finish missing from the stop above the buffer. Cheek buffer shaft for bends, mushrooming, peening and cracks on the face. Cheek shaft for oil residue. Work the buffer assembly to check for fluid leakage. Buffer shaft should depress smoothly without chatter and return promptly when released."
In the NFMC column, add: "Brier housing is peened, cracked or damaged. Buffer shaft is bent, mushroomed, peened or cracked. More than 1/8 inch of finish is missing from top edge of buffer housing stop. Buffer shaft actuates roughly or fails to return to full extended position. Buffer leaking around shaft."

WP 0028 00-5: At the end of INSPECT/REPAIR, add "M240B and N, check backplate body for damage/cracks, peening to stop above buffer shaft or finish missing from stop. Check buffer for signs of leakage, shaft damage and presence of screw plug in rear.
"If damage to the backplate exists to include more than 1/8 inch of the finish missing from the stop, replace the buffer assembly.
"If the buffer itself shows damage or signs of leakage and the stop shows less than 1/8 inch of finish missing, replace the hydraulic buffer and touch up the stop with solid film lubricant to restore a visual reference point for future wear to the stop."
