WARNING: PUT ON SAFETY GOGGLES WHEN INSTALLING OR REMOVING SAFETY WIRE.
WARNING: USE THE CORRECT PERSONAL PROTECTION EQUIPMENT TO AVOID INJURY.

ENSURE AREA IS FREE OF MOVABLE OBJECTS THAT COULD IMPACT BY
PROPELLER AIR BLAST.

WARNING: ADHESIVE SEALANT IS TOXIC AND FLAMMABLE. DO NOT BREATHE VAPORS.

AVOID EYE AND SKIN CONTACT. USE PROTECTIVE GEAR. IN CASE OF EYE
CONTACT, FLUSH WITH WATER FOR 15 MINUTES AND SEEK MEDICAL ATTENTION.

WITH WATER FOR 15 MINUTES AND SEEK MEDICAL ATTENTION. IN CASE OF SKIN
CONTACT, WASH WITH SOAP AND WATER.

WARNING: DO NOT INSTALL THE IGNITION HARNESS “B” NUTS ON THE SPARK PLUGS UNTIL

THE PROPELLER INSTALLATION IS COMPLETED. FAILURE TO COMPLY COULD
RESULT IN BODILY INJURY WHEN THE PROPELLER IS ROTATED DURING
INSTALLATION.

WARNING: IF ONE SURFACE IS POLISHED TO UNDERSIZE, ALL CORRESPONDING SURFACES

MUST BE POLISHED TO THE SAME SIZE.

WARNING: PLACE A SUITABLE STAND UNDER THE AIRCRAFT TAILCONE IF NEEDED BEFORE

REMOVING THE ENGINE. THE LOSS OF WEIGHT MAY CAUSE THE AIRCRAFT TAIL
TO DROP.

WARNING: DO NOT DAMAGE THE NITRIDED SURFACES OF THE CRANKSHAFT.
WARNING: USE CORRECT PERSONAL PROTECTION. SOME CHEMICAL SOLUTIONS CAN CAUSE

EYE, SKIN, AND LUNG DAMAGE. FOLLOW THE MANUFACTURER’S INSTRUCTIONS
FOR EACH STRIPPING SOLUTION.

WARNING: USE THE CORRECT PERSONAL PROTECTION. USE OF A HAMMER CAN CAUSE

LOOSE PARTICLES THAT CAN GET IN YOUR EYES.

WARNING: DO NOT ROTATE ENGINE OR CRANKSHAFT BEFORE REMOVAL OF TIMING

LOCATOR PINS.

WARNING: TO PREVENT THE POSSIBILITY OF SERIOUS BODILY INJURY OR DEATH, BEFORE

MOVING THE PROPELLER DO THE FOLLOWING:

VERIFY ALL SPARK PLUG LEADS ARE DISCONNECTED. •

•

VERIFY MAGNETO SWITCHES ARE CONNECTED TO MAGNETOS AND THAT THEY
ARE IN THE “OFF” POSITION AND “P” LEADS ARE GROUNDED.

•

THROTTLE POSITION “CLOSED.”

•

MIXTURE CONTROL “IDLE-CUT OFF.”

•

SET BRAKES AND BLOCK AIRCRAFT WHEELS. ENSURE THAT AIRCRAFT TIE
DOWNS ARE INSTALLED AND VERIFY THAT THE CABIN DOOR LATCH IS OPEN.

•

DO NOT STAND WITHIN THE ARC OF THE PROPELLER BLADES WHILE TURNING
THE PROPELLER.

Introduction

Overhaul Manual

O-360 and IO-360 Series Engines

DESCRIPTION AND OPERATION

General Description

Superior Vantage Engines are four-cylinder,
horizontally opposed, air-cooled, direct drive
powerplants incorporating a wet sump, bottom
mounted induction, bottom exhaust with either
carbureted or port injected fuel systems.
Provisions exist for both front and rear mounted
accessories. All engine components will be
referenced as they are installed in the airframe.
Therefore, the “front” of the engine is the
propeller end and the “rear” of the engine is the
accessory mounting drive area. The oil sump is
on the “bottom” of the engine and the cylinder
shroud tubes are on the “top”. The terms “left”
and “right” are defined as being viewed from the
rear of the engine looking toward the front.
Cylinder numbering is from the front to the rear
with odd numbered cylinders on the right side of
the engine. The direction of crankshaft rotation
is clockwise as viewed from the rear of the
engine looking forward unless otherwise
specified. Accessory drive rotation direction is

defined as viewed from the rear of the engine
looking forward.

Continued Airworthiness

Vantage Engines discussed in this document
must be installed and operated in accordance
with the limitations, conditions and operating
procedures described in the Installation and
Operation Manual (SVIOM01). They must also
be maintained in accordance with this manual
and the applicable Overhaul Manual
(SVOHM01) and other Instructions for
Continued Airworthiness. The engine’s time
between overhaul (TBO) period is initially
defined as 1000 hours. A TBO extension
program is in process.

Model Designations

The model number designation is defined in a
way that the digits of the model number can
easily identify the basic configuration of the
engine as described in Figure 02-00-00.1.
