CONTROL STICK ASSEMBLY & INSTALLATION - (FINISHING KIT)
ASSEMBLY
1.
Refer to the parts catalog and select the required components for assembly.
2.
Drill out (1) of the control stick's lower hole to 1/4" diameter. Refer to
FIGURE 10-02. The other control stick has a 3/16" bolt inserted and does not
need to be drilled.
3.
Locate and drill a 1/4" hole on the inboard side of each control stick for exit of
trim control wire and push to talk switch wire. Refer back to FIGURE 10-02.
IMPORTANT: Drill above the pivot tube of the control stick.
4.
Grease the thrust bearings and the outside of the control stick torque tube's pivot
stubs. Slip the control sticks onto the torque tube with the washers and bearings
in the order shown in the PARTS MANUAL DRAWING. Tighten the 3/4" Nyloc
Nut until it takes out all the play in the stick, but is not too tight causing binding.
5.
Assemble the control stick link tube as per FIGURE 10-05. Assemble the unit to
the control stick connector tubes.
6.
Adjust the control sticks to parallel using the rod end.
IMPORTANT: Make sure the Rod End is engaged at least 10 full
threads. Do NOT forget the Loctite and Locking Nut.
7.
The fixed end of the link tube uses a 1/4" diameter bushing slightly longer than
the link tubes bushing to allow the bolt to be tightened, and not bind the bushing.
8.
Fabricate the bushing using the 1/4" x .028" aluminum tube provided.
HINT: For easier fabrication, drill out the inside diameter to #11 before
cutting to length.
9.
Measure the link tube bushing and add 1/32" for the inner bushing cut length. It
should measure approximately 21/32". Apply grease to this bushing and the pivot
tube prior to assembly. The 3/16" bolt must be tight enough to hold the alignment
to obtain proper cable clearance and the link tube must swivel freely. Do NOT
forget cotter pins where needed.
Thread the 1/4" Plain Bolts into the 2 welded threaded nuts on the Torque Tube.
10.
These will be used as control throw stops for the tabs on the Link Tube. Do NOT
forget the Locking Nuts.
