Cyclic Bellcrank Replacement (L/H
Command)
A. Lateral Control Rods and Sta. 67 Lateral
Cyclic Bellcrank Removal (L/H Command)
(1). Remove large (central) cyclic stick
guard.
(2). Remove pilot’s seat cover, and controls
access door from Sta. 78.50 canted
bulkhead.
(3). Remove pilot’s lateral control rod, or
Sta. 70 lateral control rod, as applica-
ble.
(4). Remove Sta. 67 lateral cyclic bellcrank
from seat structure fitting.
(5). If rod or rod ends require replacement,
accurately measure and record distance
between rod end bearing centers for use
at replacement.
B. Lateral Control Rods and Sta. 67 Lateral
Cyclic Bellcrank Installation (L/H
Command)
(1). Check that slotted bushing is in upper
web of seat structure fitting. Align Sta.
67 lateral cyclic bellcrank and install
attaching hardware.
(2). Check that slotted bushings are in
place and install Sta. 70 lateral control
rod and pilot’s lateral control rod.
(3). Move cyclic stick full forward, then full
aft and set pilot’s lateral control rod end
bearing angularity so that bearings do
not jam at full travel positions.
(4). If control rod or rod ends are replaced,
perform a cyclic control rigging check.
