5. Assembling the control bridge

(bag UM-11B)
Press the ballrace 4607.137 into the control ring 4618.62 as far as it will go. Apply a little thread-
lock fluid to the control sleeve 4618.61, taking care not to allow it to run between the control ring
and the control sleeve. Push this assembly onto the control sleeve, with the inner ring of the
ballrace resting against the flange of the control sleeve.
Fit the two ball-links 4618.55 on the control bridge 4618.61, slide it onto the control sleeve, and
press it against the inner ring of the other ballrace. Press the shakeproof washer 1291.26 on the
control sleeve and against the control bridge.
Check that the control ring can rotate easily on the control bridge, but without any axial play at
all. If the ring is stiff to turn, it is likely that the two bearings are stressed against each other, and
this can usually be corrected by tapping them with the handle of a screwdriver.
Fit the control bridge on the tail rotor shaft, then engage the actuator lever on the ball on the
control ring, and tighten the M3 x 22 screw so that the lever and control bridge move freely but
without slop; finally secure it using the M3 self-locking nut.
