Installing the AeroConversions Oil Separator

(Rev B 032613)

While the AeroConversion's oil separator can be adapted to
nearly any engine/airframe installation, these instructions illus­trate an installation on an AeroVee engine. AeroConversions

and Sonex Aircraft offer no specic advice for tting an oil
return line to any engine other than those covered in these
instructions.

Oil Separator Features

Breather Input

1/2-14 NPT
Includes Steel Ball
for Inverted Flight

Mounting Bracket

Oil Separator Parts

The Oil Separator Assembly (ACV-S03-01) consists of:
ACV-S03-01, Oil Separator
ACV-S03-14, Steel Ball Bearing

How It Works

Oil vapor that enters your engine's oil breather is routed to the
separator where it is collected. A steel ball in the breather input

port prevents excessive oil loss during inverted ight.

An oil drain / return port on the bottom of the separator allows
collected oil from the separator to return to the engine via an
oil return hose connected to a low point on your engine's oil
sump, or be collected in the separator and drained.

The vapor port vents vapor out the bottom of the aircraft with­out excessive oil residue.

Mounting the Separator

The oil separator must be mounted in a position that permits
the oil drain port to be above the engine's oil level in normal

ight attitudes. When selecting a location for the oil separator

keep in mind the need for access to the oil drain port if an oil
return line to the engine will not be installed.

Connecting the Ports

Breather Input Line

The oil breather line from the engine is attached to this 1/2-14
NPT threaded port.

Note: Install the steel ball in the port prior to installing a

tting in the breather port. The ball prevents oil loss during
negative G maneuvers.

AeroVee Installation Recommendation: Install an AN842­10D hose elbow in the breather input and use a 5/8" I.D.
oil-proof hose between the oil separator and the 5/8" O.D. tube
attached to the AeroVee's oil breather plate. Secure the hose
with hose clamps.

This separator is shown with an AN912 reducer and AN842
hose elbow.

Vapor Line Out

This is the outlet for vapor and it should be vented out the
bottom of the airplane. This port will also vent oil if the oil

separator is allowed to ll before being drained, or if the drain

is not plumbed back into the engine.

This port is a 5/8" O.D. tube which will accept an oil-proof
5/8" I.D. hose held in place by a hose clamp.

Oil Drain / Return Port

The drain can be plumbed back to the bottom of the engine to
return oil to the case, or it can be plugged so captured oil can
be periodically drained.

The 1/2-14 NPT oil drain / return port.

This port will accept any variety of ttings. Do not use
barbed ttings and hose clamps for the oil return line. Use
only threaded AN hose ttings for critical connections.

AeroVee Installation Recommendation: Install an AN912-

5D reducer in the oil drain port and then install an MS20822­6D elbow in the reducer.

If the AeroVee engine is equipped with an oil temperature
plate (see photo, below), tap the plate (1/4NPT) to accept an
MS20822-6D elbow and attach a -06 braided hose equipped

with -6AN hose end ttings between the elbow in the plate and

the separator.

The 5/8" O.D. vapor line is identied by the arrow.
