Position thrust control position transducer
assembly (1) on idler arm (2) and fulcrum (3).
When a light washer is used under the
nut prior to applying nut torque, make
certain that washer does not hang up
in the bolt retaining groove. If this
condition is allowed to exist, damage
can result to associated hardware
and/or prevent proper clamp-up.
NOTE
Bolt and nut installation is not
acceptable if, after tightening nut
to torque value, the bolt and nut
assembly can be rotated with a torque
less than 10 inch-pounds and/or
any axial looseness exists. If either
condition is present, add washer
under nut and retorque.
