2-24. REPLACE/REPAIR THROTTLE ACTUATOR, QUICK RELEASE LINK, AND MAGNETIC
PICKUP (Continued)
3 Inspect the rod end bushings for elongation or wear that would cause binding or jamming.
4 Inspect for stripped or damaged threads on the threaded rods, and the screw captive in the actuator arm. If threads
are worn or damaged in the area of the locking nuts, replace the damaged component.
5 Check operation of the quick-disconnect fittings on the linkage. The fittings should hold firmly when connected and not
bind or catch when released.
WARNING
Severe burns, illness, or death could occur if diesel fuel oil is not
handled carefully. Use in a well-ventilated area away from open
flame, arcing equipment, ignition sources, heaters, or excessive
heat. Do not inhale vapor. DO NOT SMOKE.
Death or serious injury could occur if compressed air is directed
against the skin. Do not use compressed air for cleaning or drying
unless the pressure is/has been reduced to 30 psi (2.11 kgcm2) or
less. When working with compressed air always use chip guards,
eye protection, and other personal protective equipment.
6 Use a lint-free cloth dampened with diesel fuel oil to clean the actuator. Remove all traces of grease and dirt. Dry
actuator with compressed air. Inspect for minor rust, corrosion, or other damage. Replace if severely rusted or
damaged.
REPAIR:
1 Do not attempt to straighten or reshape quick release link components or lever extension. Alinement and dimensions
of these components are critical to proper operation of the engine throttle and speed control. Replace components
that are bent or distorted.
2 If the actuator is damaged or has malfunctioned, it must be replaced. A faulty actuator could result in overspeed or
overload conditions that would seriously damage the engine.
3 Remove rust, corrosion, or dirt from the sensor and terminals of the magnetic pickup. Replace pickup if insulation is
cracked, if sensor head is damaged, or if threads along the body are stripped.
