Austral Oil Engine No.182/755

Originally a pushrod engine built c1908. Rebuilt as a sideshaft engine in October 1911.

Delivered 25/5/1912. 'First start' 30/5/1912.

I purchased this engine in October 2010. It finally made it home in March 2012.

This engine exhibits a number of features different to the 'standard' sideshaft engine. The inboard silencer and different cooling tower are retained from its originally build and the toolbox is mounted where the silencer is fitted on later engines. The transporter wheels and axles are different to later engines. The engine is mounted further back than normal meaning that the water pump eccentric is much further along the sideshaft.

Below is an image of what the engine would have looked like when originally built as a pushrod engine.

All loaded up for the trip home. Due to the soft ground it had to go on backwards. It will not be loaded this way again as the weight was too far back.

Home at last and Samuel is happy I have brought him another toy
