❏
Paint the inside of P/N 663 and the outside of P/N 656 (where P/N 663 will be installed)
with zinc chromate primer. If you use spray paint, temporarily install the Schrader valve
during the painting operation.
❏
If you wish to install the nose gear fork permanently, torque the MS21042-5 nuts to 100 to
140 inch-pounds (8.33 to 11.67 foot-pounds).
❏
If the upper surface of the nose gear piston base and the first 6 to 8mm of the piston is
painted with zinc chromate primer, slide P/N 664 stop to the bottom.
❏
Install P/N 661-2 upper torque link. The three bolts for the torque links should not be
tightened. Tighten the nuts finger tight and then back off one half turn. The cotter pins
may be installed, but you will probably want to disassemble the nose gear for final painting
before flight.
❏
Centerpunch P/N 663 nose gear rocker arm on the forward side. (The two arms are angled
toward the front.)
❏
Drill through one side of the large short center tube of P/N 663 with a 5/32” drill.
❏
Put P/N 663 nose gear rocker arm on the top of the nose gear strut. Do not drill the bolt
hole yet.
❏
Align the nose gear rocker arm with the nose gear fork. The two arms on the rocker arm
are angled toward the front, and the torque links and P/N 665 eyebolts are also on the
front of the nose gear. Be sure that the rocker arm is correctly aligned before drilling
through!
❏
Drill through P/N 656 and out the other side of P/N 663 with a 5/32” drill.
❏
Check the alignment of the nose gear rocker arm and correct as needed.
❏
Ream the hole with a 11/64” drill.
❏
Ream the hole with a 3/16” drill or a 3/16” reamer.
❏
Remove the rocker arm and deburr all holes.
❏
Coat the outside of the nose gear strut with oil to protect it from corrosion. This will apply
only to those areas that will be enclosed in the nose gear trunnion.
❏
Coat the inside of the nose gear trunnion with oil to protect it from corrosion.
❏
Install the nose gear strut in the nose gear trunnion.
❏
Install P/N 616 upper ring nut.
Note: You should paint the nose gear at a convenient time later in the construction
process, since you will find it a lot of trouble to set up to paint just one part now. For this
reason, do not install the locking screws in the upper ring nut, axle and axle nut at this
time.
