Assemble Primary Hydraulic Pump
1. Clean all parts and inspect for wear or damage. Damage to any component of either cartridge
group, except seals, will require replacement of the complete cartridge group. See Diagnosing
Hydraulic Pump Failures (Form No. SEBD0501.
2. During assembly, all components must be installed in the correct direction of pump rotation.
Pump rotation as seen from the drive end of the shaft is counterclockwise. Put clean oil on all
parts during assembly.
3. Use tooling (B) and install lip type seal (43) in the pump body. Install the seal with the lip
toward the pump shaft bearing.
4. Turn the pump body over. Use tooling (B) and install the inner lip type seal. Install the seal with
the lip toward the pump shaft bearing.
