Brief Description: Removed the Engine From the Aircraft
Removed the Engine From the Aircraft. Small pieces of perforated steel angle were bolted to the top of the engine block for lifting. The angles were attached using fine thread M10 bolts (M10 x 1.25 x 20mm). Removed the Engine from the firewall after adjusting the attitude of the fuselage until there was no tension on any of the mount bolts. A board was positioned under the center section and jacked up enough to lift the nose gear off of the ground and achieve the no bolt tension attitude. The engine slide easily off of the bolts. Next, the engine mount was removed from the engine. This was followed by the removal of front plate. The Spline Adapter Plate was initially a challenge. It was supposed to be removed with gentle prying but it would not move until the hex cap bolts were removed. These bolts had SAE hex fittings vs metric hardware common on the rest of the engine. More prying and trhe spline adapter plate slid off. The spline was then supposed to easily slide out of the flywheel but this did not happen either. So, the flywheel was taken off by removing the eight T-50 torx attachment bolts holding it in place. Using a wooden block, then a punch, the spline was tapped out of the pilot bearing in the center of the flywheel. Inspection of the spline showed the spline to be in good condition without any obvious wear.
