value.
39. Route all the oil lines in accordance with the parts manual. Be certain to avoid
sharp bends or kinking the lines. On the oil line from the pump to the tank, you
will need to use the banjo bolt that comes with the oil line, not the one that is
supplied by ROTAX, it does not have enough thread to be used with the fitting on
the supplied oil line. Torque all fittings to AN value.

ROTAX 915iS – INTERCOOLER INSTALLATION

AIRBOX ASSEMBLY

1. Gather the parts needed to assemble the airbox for the intercooler.
2. Starting with the top or bottom air scoop cover and the inboard air scoop, line the
aft edges up. The inboard air scoop will go inside of the bent flange of the top
and bottom cover.
3. Once lined up and with the bent edge of the inboard air scoop facing forward and
the bend going towards the engine, begin transfer drilling #30 the tab holes of the
top/bottom cover, to the inboard air scoop. Cleco as you go. It will take a solid
push to press the inboard air scoop into the curvature of the top/bottom cover.
4. After either the top or bottom cover is transfer drilled and clecoed, proceed to the
other cover. Transfer drill and cleco.
5. Install the Air Scoop Attach Brackets to the intercooler. Ideally, they will fit with
the bolts being centered on the slots. Lightly tighten the hardware.
TEXT MANUAL
Refer to the ROTAX 915iS Installation Manual for their specific
instructions on filling with oil and purging the oil system before
engine startup.
HINT: A vertical positioned 2 x 4 clamped into a vice makes
for a good tool to push on the air scoop while transfer drilling
the holes.
