compound (C-101) to exposed threads of all
adjustable rod bearings and devises after
adjustment.
76.3.1.2.1.5
Torque control tube jamnuts 80
to 100 in-lbs (9.0 to 11.3 Nm) after adjustment
unless otherwise specified.
76.3.1.2.1.6 Control
tubes must be free to
rotate several degrees about longitudinal axis. If
necessary, loosen jamnuts, adjust end fitting
and re-torque jamnuts.
76.3.1.2.2
If not previously accomplished,
rig collective control system (Chapter 67).
76.3.1.2.3
Verify proper throttle flex shaft
to gear sector engagement as follows:
76.3.1.2.3.1
Disconnect tube (14, Figure 76-
3).
76.3.1.2.3.2 Disconnect
control tube (9) from
rod end bearing (7).
76.3.1.2.3.3
Inspect marked tooth (41) on
pilot engine flex shaft (40) to ensure
engagement of tenth tooth space on pilot engine
gear sector.
76.3.1.2.3.4
Inspect gear sectors and flex
shafts at base of copilot collective stick in same
manner outlined in steps 76.3.1.2.3.3.
NOTE
If dual controls are installed
accomplish step 76.3.1.2.3.5, do not
accomplish step 76.3.1.2.3.6. If
dual controls are not installed
accomplish step 76.3.1.2.3.6, do not
accomplish step 76.3.1.2.3.5.
76.3.1.2.3.5
If dual controls are installed,
position pilot throttle (2) to full open position
against stop. Position copilot throttle to full
open. Hold twist grips in position against stops.
Do not accomplish step 76.3.1.2.3.6. Proceed
to step 76.3.1.2.3.7.
76.3.1.2.3.6
If dual controls are not installed,
position pilot throttle (2) to full open position
against stops. Hold twist grip in position against
stop. Position copilot gear sector (44) as shown
in View D. Hold gear sector in position while
accomplishing steps 76.3.1.2.3.7.
NOTE
Controls must be positioned as
described in step 76.3.1.2.3.5 or
step 76.3.1.2.3.6 as applicable,
prior to accomplishing steps
76.3.1.2.3.7.
76.3.1.2.3.7
Adjust control tube (9) to fit
double rod end bearing (7). Torque jamnut on
control tube (9) clevis. Install control tube (9) on
double rod end bearing (7).
76.3.1.2.3.8 Move pilot throttle controls
through the full range and verify for binding
and/or obstruction of control movement.
76.3.1.2.3.9
Check pilot engine flex shaft
(40) pinion and mating gear sector at base of
pilot collective in same manner described in
preceding step.
76.3.1.2.3.10 Check
gear sectors (44) at the
base of copilot collective in the same manner
described in steps 76.3.1.2.3.8.
76.3.1.2.4
Ensure that flight idle stop
solenoid (19, Figure 76-3) will not engage.
(Loosen bolts and allow bracket (21) to be low
enough not to engage cam.)
76.3.1.2.5
Ensure that adjustable rods (14
and 35) are to nominal dimensions.
76.3.1.2.6
Ensure that tube assembly (14)
is positioned in center of slot of bellcrank (15).
76.3.1.2.7
Rotate twist grip (2) to full on
and full off and cheek that overtravel of twist grip
is equal.
