CHECK SWASHPLATE BEARING FRICTION
RECHECK SWASHPLATE BEARING FRICTION
The force needed to move the
swashplate may not exceed 30
pounds. Step 7 may not be
performed more than once.
If the force required to move swashplate ring
(9) in step 5 exceeded 30 pounds, proceed as
Pump grease (E190) into swashplate
stationary ring (10) to purge old grease (Task
1-90). Rotate ring (9) 360º as grease is
pumped. Fill until clean grease appears at
least 3/4 of the distance around seals (5
Check purged grease for metal particles.
There shall be no metal particles. If metal
particles are found, replace the swashplate
(Tasks 5-116 and 5-132 (forward) or Tasks
5-117 and 5-133 (aft)).
Repeat steps 4 and 5. If required force does
not exceed 30 pounds, go to step d. If it
exceeds 30 pounds, replace the swashplate.
Connect lower drive arm (1) to swashplate
lug (2) (Task 5-112). Connect pitch links at
the lower end (Task 5-99).
Check that 18 nuts (11) at the bottom
of rotating ring (9) are torqued to 365
inch-pounds (TM 1-1500-204-23).
