5th October 2011 - Installing the engine

As a change from covering I decided to install the engine. This needs to be in place to fit the cowl and build the baffles which control the cooling airflow around the engine. Both of these are likely to be biggish jobs. The engine had been returned from the shock load inspection without cylinders which were not part of the inspection and were stored separately. In this state it was easy to manually lift the engine up onto a bench and then the aircraft could be positioned to align the mounting bolts. Once these were in place the cylinders were installed together with the fuel pump, the vacuum pump, the magnetos, the starter, the priming lines, the tacho drive, and the cylinder head temperature sender. I still need to make a bracket to support the throttle cable and mixture cable before I can mount the carburettor. Also, the alternator I'm going to be using doesn't align with the flywheel pully using the standard Lycoming mount so this will need to be modified. The engine is unpainted at the moment. Once everything is set up and the cowl and baffles are complete I will remove the engine as a complete unit and paint it before final assembly of the aircraft.
