CHECK SWASHPLATE BEARING FRICTION
On the aft swashplate only, check that bolts (3)
and bolts (4) are lockwired.
Check that grease appears in a continuous bead
all around overlap between stationary seal (5)
and rotating seal (6).
Hook dial scale (7) to a pitch link lug (8). Position
the scale at 90º to the lug.
Do not use the reading indicated
as the swashplate starts to move.
Starting friction force is greater than
rotating friction force.
Pull scale (7) to move rotating ring (9). Read the
scale while the ring is moving. While the ring is
moving, keep the scale at 90º to lug (8). If the
indicated force is less than 30 pounds, continue
with step 6. If the force is more than 30 pounds,
go to step 7.
Connect lower drive arm (1) to swashplate lug (2)
(Task 5-112). Go to Follow-On Maintenance.
