4.3.4.6.3 Procedure
In case if balancing of the stabilator is necessary (replacement, repairing surface of the stabilator \ trim
tab or changing stabilator bracket), it should be done by means of change of the balancer weight in small
increments continuously checking balance. While checking balance, the 6 bolts (Fig. 6, pos. A) have to be
screwed in, but not tightened. The stabilator, bracket and axle are to be set on some supports so, that the
stabilator could freely wobble around the axle of rotation.
•
To reduce balancer weight
Screw out the 6 bolts pos. A.
Take off the necessary quantity of the lead fraction from the inside of the balancer (Fig. 6, pos. B) and
check balance with the bracket installed onto the stabilator. Upon completion tighten the 6 bolts to 200 lb-
in / 22.5 N*m using the lock liquid of middle strength Loctite 243.
•
To increase balancer weight
Screw out the 6 bolts (Fig. 6, pos. A)
Add the necessary quantity of lead fraction inside the balancer (Fig. 6, pos. B). After balance is set, put
epoxy resin inside the balancer to fill empty space. Tighten the 6 bolts pos. A to 200 lb-in / 22.5 N*m
using the lock liquid of middle strength Loctite 243
