Gear Pumps and Motors Group 2 5. Disassembly General In the following pages a detailed procedure is given for disassembly and assembly of pumps and motors. Prior to proceeding it may be necessary to prepare some subassemblies separately. The details for preparing each subassembly are given in the following section.
Gear Pumps and Motors Group 2 5.1.5 Procedure 1. Clamp the unit. Clamp the unit in a vice from the flange side. Make sure the vice jaws are clean and have smooth surfaces to prevent damage to the pump. Clamping the pump on the body is not recommended because serious damage to the surfaces, on which the ports are located, may occur.
Page 194
Gear Pumps and Motors Group 2 4. Remove front flange. Place the pump on the table and slowly remove the front flange. Be careful not to damage the shaft seal when removing the flange. Avoid contact of the shaft seal lips with keyway edges (in tapered and parallel shafts) or splined shaft teeth.
Page 195
Gear Pumps and Motors Group 2 6. Remove bearing blocks and gears. Place the pump on its side and carefully remove the bearing block and gear set. To accomplish this, hold the pump body and push with your fingers on the rear bearing block. Mark the relative positions of the gear mesh (drive gear tooth to idler gear tooth) and the bearing blocks to the body so they can be reas-...
Page 196
Gear Pumps and Motors Group 2 8. Remove Outer O-Ring Seal Check the quality of this seal. If necessary, replace it. Follow the same removal recommenda- tions given in step 7. After removal, discard the damaged seal. Important: Do not use tools with sharp edges to remove the seals, as damage to the cover can result.
