Section 75-02
Air Cooling - Lycoming O-360-A4M Engine
1. General
This Section gives you the data for the air cooling system for airplanes with the Lycoming O-360-A4M engine installed. It gives you the maintenance practices to remove/install the baffle. Refer to the Lycoming Maintenance Manual for data about the inter-cylinder cooling baffle. Figure 1 shows the air cooling baffle.
2. Description/Operation
The baffle controls the cooling air flow. Ram air enters the cooling baffle through the intake in the engine cowling. The front duct of the baffle sends the cooling air into the space over the top of the cylinders. A special rubber sealing strip is mounted at the top of the baffle. The rubber sealing strip makes a seal between the baffle and the inside of the top cowling. The air goes down between the cylinders and around the outside of the cylinders. The used air goes out from the bottom rear of the engine bay.
The cables for the top spark plugs of No’s 1 & 3 cylinders, go through a cable feed-thru in the rear of the baffle, on the right side. The cables for the top spark plugs of No’s 2 & 4 cylinder pass through holes in the left side of the baffle, at the top.
