Working from forward left work platform, position
protractor (26) on fixed swashplate (27). Align
protractor with LCT actuator (28) and LCT
connecting link (29). Measure and record angle
of swashplate. Remove protractor.
Do not rotate protractor between
measurements; otherwise, false
measurements will occur.
12.
Position protractor (26) on top of rotor shaft
(30). Align protractor with actuator (28) and link
(29). Measure and record angle of rotor shaft.
Remove protractor.
13.
Check angles measured in steps 11 and 12.
Step 11 angle must be less than step 12 angle.
Subtract angle of step 11 from angle of step 12.
Difference must be 1.0º to 1.4º. If same, go to
step 27. If not, perform steps 14 thru 26, then
repeat steps 11, 12, and 13.
