The disassembly and re-assembly procedure can be accomplished by utilizing the following instructions and drawings. Use extreme
care during disassembly and re-assembly not to mar or nick any smooth surface that comes in contact with seals. Before installing
seals, always apply a good lubricant, such as Lubriplate®, to the surfaces. It is recommended that tool kit (GB740TK) be used to
