5. Cut a 1" [25mm] piece of outer pushrod tubing from
the 36" [914mm] length supplied. Install it in the fi rewall as
shown so that 1/4" [6.4mm] of the tube protrudes forward
from the fi rewall. Roughen the surface with sandpaper and
use epoxy to glue it in place.
❏
6. Obtain four 1/4-20 x 1-1/2" [38mm] SHCS, four 1/4" [6.4mm]
lock washers, and four 1/4" [6.4mm] washers (not included).
Locate the four included 12 x 20mm aluminum spacers. Install
the engine to the fi rewall using threadlocking compound on the
threads of the bolts as an added safety measure.
❏
7. Locate the 2-56 x 6" [152mm] threaded one end rod.
Measure 2-1/2" [64mm] from the threaded end and make a
mark. Start your Z-bend at the mark so that the leg of the
bend is 2-1/2" [64mm] from the threaded tip. Clip off the
excess rod. This will be referred to as "pushrod A."
❏
8. Locate the 2-56 x 36" [914mm] threaded one end rod.
Measure 6" [152mm] from the unthreaded end and make a
mark. Cut the wire at the mark and retain this portion. This
will be referred to as "pushrod B." The remaining portion of
the rod will be used for the throttle later.
❏
9. Make a Z-bend at one end of pushrod B and a 90°
bend at the other end as shown. The last 3/4" [19mm] of rod
should be left for the 90° bend.
❏
10. Locate the nylon bellcrank and drill out the outermost
holes in the arms using a 5/64" [2mm] drill bit.
❏
11. Locate one 4-40 x 1-1/2" [38mm] cap screw, one #4
lock washer, two #4 washers, one brass bellcrank bushing,
one 4-40 nut, and one 1/2" x 1/2" x 1" [13 x 13 x 25.4mm]
pre-drilled wooden standoff block. Fit the bellcrank parts in
the order shown.
❏
12. Loosely position the bellcrank assembly as shown and
connect threaded pushrod A and pushrod B as shown. Apply
