The following set of photos show the installation of the weighbar shaft into the frames and represent the start of the installation of all the valve motion.
First job to make sure the bushes are spot on and the grease will be distributed along the shaft where it is required.
With the bearings on the ends of the shaft everything is suspended from the gantry and lowered into the holes in the frames.
One end is slid right through the frame hole to allow the opposing end to drop down inside the frames.
The entire aseembly is then slid back to centarlise it in the frames.
Lastly a bit of final adjustment to get the fitted bolts into the frames and the locking rings secured on the shaft.
