Inspection of Cylinder and Slide Valve. 

In the end of the season 2002 Vølund Junior started to sound strange. The steam strokes were replaced by a nearly constant wheezing and the engine was not willing to work.
There are only two possible explanations for this - cylinder and slide valve – it could be a broken ring.

Then we continued with the sliding valve.

Please observe the "propeller" in front of the cylinder. It is an invention of Mr. Jørgen Permin – it gives swirl to the exhaust steam to avoid soot deposits on the inside of the chimney.

In fact a ring was broken at the slide valve.
A company selling cast iron has sponsored material for a new ring, which is now installed.
