My Spare S.I.C. Engine.
 This is an S12D series Wisconsin engine, built in Australia by Ronaldson Bros and Tippett in Victoria, under licence from Wisconsin in the United States, (who were the majority owners of RB&T)

I picked up this engine last year, and am rebuilding it as a spare for the Supervisors Inspection Car I jointly own.

The engine has a seized exhaust valve, which appears to be a typical problem with these motors. All of the engines I have come across, around the country, have had a similar problem.

This engine is set up for electric start, and has a dynamo that can (or perhaps should) throw somewhere between 10 and 20 amps.

As well as unsticking the valve, I will replace the main seals and gaskets. So far the motor appears to be in reasonable shape.

Typical of this size engine, this one is "splash" lubricated. The manual I have for the S12D and AELND indicates some were fitted with a proper oil pump.

This is an S12D, but not the one in this series of pages.

This engine is also suffering a sticky valve - needing an overhaul!
