The return cranks were now fitted but will be finally pinned into position after the valve gear has all been assembled and tested. At this point they were each clamped together with a steel screw and nut. It's a good idea when doing this to hold the return clamp jaws together with a pair of pliers whilst tightening the screw and nut.
The weigh shaft, expansion links, eccentric and radius rods were all now fitted.
The assembly was now checked for a 'smooth running' prior to the fitting of the lifting arms and links.
Finally at this stage the steel reversing rod was fitted, clamped and the valve gear set to ensure that the radius rods lift at the correct time and position.
The valve timing was then checked and the valve chest covers finally fitted. (Not shown in photo.)
