IO-360-N1A Engine Installation and Operation Manual

Step 3. Remove Components

It could be necessary to temporarily remove a component, to install the engine in its compartment on
the aircraft.
Remove only the components necessary to enable engine installation.
The component(s) will be re-installed after the engine is installed.

Step 4. Install Aircraft-Supplied Engine Mounts

The airframer is to supply bonded rubber mounts and bolts for attachment to the Type 1 Dynafocal
engine mounts. There are four mounting bosses integral to the crankcase. Refer to the respective
Installation Drawing identified in Appendix B for the IO-360-N1A engine.
Maximum Allowable Load for the Mounting Attachment and Structure
The Type 1 Dynafocal mounts can withstand a 10 G load per FAA FAR requirements.

Step 5. Prepare the Aircraft Engine Harness

Lycoming Engines can supply a wiring diagram to the aircraft manufacturer, which is used to
prepare the aircraft engine harness.

Step 6. Make Electrical Interface Connections

Make electrical interface connections.
Grounding Requirements
Install grounding jumpers from the engine case to the engine mounting frame. (The engine mount
must also be grounded to the airframe).
