Assemble and fit the elevator trim assembly
Refer to the drawing on the next page: Assemble the trim pivot: press the 2 sealed bearings
into the hub and then pop rivet the assembly together. Assemble the trim spring unit, adjust
the rod end to almost full thread depth and tighten the lock nut.
Connect the trim spring unit to the trim pivot with an AN3-13A bolt through the black pivot
block in the middle of the spring assembly and the top hole in the trim pivot arm, taking
careful note of the arrangement of the washers and the sleeve between the two items.
Connect the trim cable rod end to the trim pivot with an AN3-12A bolt through lower hole in
the trim pivot arm. Fit the trim pivot to the trim horn with an AN4-14A bolt.
Fit the rod end of the trim spring unit to the bottom hole in the elevator drive arm extension
with an AN3-07A bolt.
Push the trim lever on the console fully
forward, hold the trim pivot arm fully
forward as shown at right, align the trim
cable as shown, then drill the 2 x 3/16” trim
cable clamp holes through the trim horn.
If you are working alone you can wedge the trim pivot into position for this step.
Attach the outer trim cable to the right hand side of the trim horn with 2 x AN3-06A bolts
fitted through trim horn, the clamp backing plate and then the saddle clamp and securing with
flat washers and Nyloc nuts, taking care to locate the locating key on the saddle clamp in the
locating groove in the outer cable before tightening the Nyloc nuts to safety.
Use the supplied deflection templates to re-check the up and down travel of the elevator.
