Hagerstown, MD KHGR

                         Our Engine Project

Our engine project consisted of the complete tear down and rebuilding of an O-290 Lycoming D2 engine.

A special thanks goes to Bob Schemmering for securing this motor and serving as the project manager in this endeavor. Photos of the progress in this rebuilding project can be seen by clicking on "Photo Gallery" and then selecting "The Engine Project".

-
Initial visual inspection of removed pistons and cylinders showed �no� corrosion.
-
Piston/Piston Arm Pin was removed with some difficulty, it was very tight.
-
Piston Arm swings, but not freely at the Crankshaft.
- Piston Diameter is 4-8/16 inches.
-
Cylinder Diameter is 4-9/16 inches.
-
Piston Rings were free moving on the piston and there were no signs of corrosion.

To Do List:
Dick took Cylinder and Piston No.1 for inspection and to determine from these parts what type of engine we might have. His initial guess is a older model O-235.

May 10, 2006:
From the Cylinder and Piston No.1 inspection, our motor appears to be a O-290 Lycoming D2.
