Page 3 GENERAL INSTRUCTIONS The instructions found herein cover the disassembly, assembly and parts identification of Series G3DB and AG3DB pumps. NOTE: Individual contracts may have specific provision that vary from this manual. Should any questions arise which may not be answered by these instructions, refer to the General Instructions Manual, CA-1, provided with your order.
Page 4 SUCTION STRAINER A suction strainer with adequate flow rate and minimum pressure drop should be used to keep contamination from entering the pump and system. The maximum pressure drop (when dirty) across the strainer plus all other losses in the pump suction line at maximum fluid viscosity, including static lift, must not exceed the suction lift capability of the pump.
Page 5 FLUID Use only hydraulic fluid recommended for use with the pump. Supplementary oil additives are not recom- mended. Regular checks should be made of the condition of the hydraulic fluid and the fluid level in the reservoir, and establishing when the fluid is to be changed. When adding or replacing fluid, use enough fluid to return the fluid level in the tank to its normal operating point.
Page 6 WARNING When inspecting/servicing the shaft seal and/or bearing, the power rotor with these components installed can be removed as a subassembly. If for any reason the pump is disassembled further than this, it is possible the idler rotor balance piston housings (20) may fall off.
Page 7 REASSEMBLY OF BEARING AND MECHANICAL SHAFT SEAL 1. Clean the power rotor shaft and snap ring grooves prior to installing the new seal and bearing. Wash the shaft in solvent to remove dirt and grease. Use only new bearing, seal and retaining rings. 2.
