To quickly assess the difficulty of the text, read a short excerpt:
All the valve motion for the steam cylinder is in the top head, so that in case of any failure to woi k properly a new head can be substituted until the old one can be fixed. There are a number of points in which this pump is similar to the 8-inch pump, and in which it will be liable to the same troubles. It has the same arrangement of hollow^ piston-rod, reversing stem and valve, and a similar bushing in which this valve works, and as these parts perform practically the same function in this p...ump that they do in the other, any irregularity in their action will produce practically the same effect. If the reversing-valve stem is too long between the shoulder and button the pump will pound and may not be prompt in reversing, and the same thing will occur after the reversing-valve plate or this shoulder or stem become badl}^ worn. If the distance between the shoulder and button be too small, the pump will have too much clearance and will heat in consequence. An unequal stroke w^ill result in case the lift of the upper and lower air-valves wears unevenly.
