V. Maintenance/Repair Notes
The following outlines some common maintenance/repair procedures
A) Tail
Belt
Tension
The tail rotor belt requires additional adjustment to ensure that it is at the proper tension. Use the following procedure
for the adjustment.
A.1 A.2 A.3 A.4
Repair Notes:
The correct tension for the tail
rotor drive belt must be
maintained and should be
checked occasionally. If it can be
deflected for than 1/8” at the
point shown, it should be
tightened.
Use this procedure to set the t/r
belt tension.
A.5 A.6 A.7 A.8
Repair Notes:
Pull the tail boom backwards to
tighten the belt.
The slots in the front t/r servo
mounts will allow the servo to
move with the boom. This
eliminates the need to readjust
the t/r pushrod length
Recheck belt tension. Tighten
until it deflects 1/8” here.
Repair Notes:
When the tension is correct,
realign the tail boom by lining
up the vertical fin with the side
frame, and tighten the bolts
using thread lock.
