Subtask 32-31-00-700-053-A
A. Test
(1) If the conditions that follow are shown, do the fault isolation.
(a) During retraction and extension of the landing gear there is vibration and noise.
(b) During servicing, the MLG FWD pintle bearing is difficult to lubricate.
4. Fault Isolation(1) If the conditions that follow are shown, do the fault isolation.
(a) During retraction and extension of the landing gear there is vibration and noise.
(b) During servicing, the MLG FWD pintle bearing is difficult to lubricate.
Subtask 32-31-00-810-113-A
A. Procedure
NOTE: Not sufficient lubrication of the FWD pintle bearing can cause vibration and noise, and/or MLG FWD pintle bearing difficult to lubricate.
(1) Lubricate the FWD pintle bearing AMM 12-22-32-640-001, use both grease nipples (when accessible). Lubricate for another 20 strokes after fresh grease comes out of the pintle bearing.
