On Friday 4th January, the safety valves were tested and the springs removed.
On Saturday, the valve spindles were removed. This requires removal of some of the running plates, and then disconnection of the operating rods. This has to be carried out in a confined space, as is often the case. The photo shows the left hand side being dismantled.
Then the valve cylinder front cover has to be removed and the valve spindle extracted from the front. The photo shows the right hand side valve cylinder with the front cover removed.
The valve spindles were then measured to check for wear.
