OVERHAUL
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 (GB730TK) be used to
facilitate overhaul. A complete overhaul can be achieved by the use of Service Kit 730006 which contains a complete set of o'rings,
back-up rings, screws, washers and gasket. It is recommended that this service kit be kept available for spare parts.
