During scheduled quarterly servicing of tactical quiet generator (TQG) sets, maintenance personnel must inspect the mechanical governor actuator linkage. Before adjusting the linkage turnbuckle, technicians must loosen the jam nuts on both rod ends and verify that the throttle lever rests fully against the low-idle stop screw. The linkage rod must be set to provide exactly 0.125 inches of free travel before engaging the governor spring arm. Applying excessive torque to the aluminum bellcrank during adjustment can distort the internal pivot bushing, leading to erratic engine surging.
According to the passage, what condition must technicians verify before adjusting the linkage turnbuckle?
- AThe linkage rod provides exactly 0.125 inches of free travel.
- The throttle lever rests fully against the low-idle stop screw.Cevap
- CThe aluminum bellcrank is torqued against the internal pivot bushing.
- DThe jam nuts on both rod ends are torqued to 0.125 foot-pounds.
