Midterm Flashcards
Where are the critical fatigue areas?
Areas where the cable runs over, under or around a pulley, sleeve or fairlead. Any section where the cable is flexed, rubbed or worked. Any point within 1 foot of a swagged fitting
What do you check control cables for
Condition, attachment, alignment, clearance and proper operation.
What do you inspect swage fittings for
evidence of slippage (paint marks) also for broken wires
What will solvents do to the cable
Remove lubricant allowing cable strands to abrade
After cable cleaning, what do you apply
Corrosion-preventative compound (Par al ketone) is a waxy grease
What do you inspect cable runs for and where do you inspect
incorrect routing, fraying, twisting or wear at fairleads, pulleys, anti-abrasion strip and guards
What can cables interfere with
adjacent structure, equipment, wiring plumbing, and other controls
What do you inspect pulleys for
roughness, sharp edges, presence of foreign materials embedded in groves
What do you inspect pulley bearings for
ensure proper lubrication, smooth rotation and freedom from flat spots, dirt and paint spray
What should you do to the pulley bearings during inspection
Rotate the pulleys, which only turn through a small arc, to provide a new bearing surface for the cable.
What do you check pulley brackets and guards for
damage, alignment and security
What are fairleads and rub strips made of
phanolics, phormica or plastic
What are pulleys made of
Phanolic, permica, aluminum or plastic
What do you inspect fairleads for
wear, breakage, alignment, cleanliness and security
What are pressure leads filled with and what do they improve
Grease to help improve longevity and lubrication
