BALL SPHERICAL BEARING FRICTION CHECK
Attach dial indicating scale (21) to bolt (18).
Pull scale (21) down in curved motion following
path of swashplate (16) as it tilts. Read scale
after ring begins to move. Force needed to keep
swashplate moving shall be between 1.25 and
Do not read force needed to start
swashplate tilt. This includes added
force needed to over come inertia.
If force in step 15 is 1.25 pounds or less, check
axial movement of swashplate stationary ring
(20). If movement is more than 1/8 inch, replace
swashplate (16) (Tasks 5-115 and 5-132, or
Tasks 5-166 and 5-133).
If force in step 15 is more than 63.5 pounds,
replace spherical bearing (Task 5-125).
If bearing replacement does not
reduce force to move swashplate
to within limits, replacement of the
swashplate (16) may be necessary.
(There is no limit to the number
of bearing replacements that can
be accomplished; however, good
judgment should be used.)
Remove scale (21). Remove bolts (18).
Position lugs (19) over actuating cylinders (7
