4. Install front portion of throttle body. See the next step for
entire assembly installation.
a. See Figure 4-100. If front portion of throttle body
was removed, lubricate surface of seal ring (5) that
will contact manifold.
b. Press throttle body into manifold.
c. Place hook (3) on bottom rail (2) over tab (4) on
manifold. Secure with two screws (1) (metric).
5. Install throttle body and intake manifold as an assembly.
a. See Figure 4-101. Standing on the gearcase cover
side of the vehicle, slide the assembly toward
installed position. Manifold should slide over screws
on primary cover side of engine.
b. Align holes in intake flanges with those in cylinder
heads and start screws. For best results, use a 1/4
inch Allen head with end driver 8 inches long.
c. Make sure throttle body is centered between cylin-
ders and tighten all intake flange screws to 6-10 ft-
lbs (8-14 Nm).
6. Attach wiring.

ease of assembly. Push connector halves together
until latches “click.” Grooves in female connector
must align with the tabs in male housing.
b. Connect throttle position sensor by pushing the con-
nector halves together. Slots on female connector
must fully engage tabs on male connector housing.
