place, and install the valve cover clamps (43) over the valve
cover studs (59). FMC recommends replacing the valve
cover washers (60, if installed) and the valve cover hex
nuts (52) if any of these parts are visually deformed.

recommend values listed in the Fastener Torque

10.3.1 Valve Assembly and Knock Out Tool
The simplest of the tools is the removal and installation tool, part number P534695
(small ball). For disc valves, P534694 (large ball) tool should be used.
To remove a ball valve, this tool is inserted from the bottom of the fluid cylinder and is
stopped by the bottom of the valve seat. The tool is struck firmly with a hammer and the
valve is loosened. The suction valve can be removed first through the cylinder cover
and the discharge valve through the valve cover.
