IO-360-N1A Engine Installation and Operation Manual

Overview

NOTICE: All requirements identified in this chapter must be completed before the engine can be

installed. These requirements are for a new, rebuilt or stored engine to be placed into

service.

As an overview Table 1 identifies the necessary steps that must be done before the engine can be

installed.

Step 1. Prepare the Engine

To prepare a new, rebuilt, or overhauled engine

To prepare an engine that has been in storage

Prepare a New, Rebuilt, or Overhauled Engine for Installation

NOTICE: The engine is sent from the factory with preservative oil in the cylinders and in the

crankcase. A preservation date stamp (usually on the engine box) identifies the date this

oil was added and preservation is good for 60 days afterward. If an intake valve was

open, the preservative oil can get into the induction system of the engine. All

preservative oil must be removed per this procedure.

To prepare the new, rebuilt, or overhauled engine for installation in the airframe:

DO NOT TURN THE CRANKSHAFT OF AN ENGINE WITH

PRESERVATIVE OIL BEFORE REMOVAL OF THE BOTTOM SHIPPING

OR SPARK PLUGS. OTHERWISE, ENGINE DAMAGE, CAUSED BY

HYDRAULIC LOCK CAN OCCUR.

1. Lift the engine. Refer to the section "Lift the Engine" in the "Engine Reception and Lift" chapter

in this manual.

2. Complete the preservative oil removal procedure as follows:

A. If any of the dehydrator plugs (which contain crystals of silica gel) break and the crystals fall

into the engine, complete the following per the IO-360-N1A Engine Maintenance Manual.

 Disassemble the affected portion of the engine.
