Assembling the Gear Pump
ProLine H800
19241SL Rev A
Note: When assembling the gear pump, check the marker line made during the
disassembly to ensure that the parts are properly aligned during the assembly.
1. Apply clean hydraulic fluid to all the parts before you assemble them.
Note: The pressure seals and back-up rings fit in the grooves machined
into the thrust plates. The body seals fit in the grooves machined in the
body faces.
2. Assemble the pump section starting at the front cover end. Apply grease or
petroleum jelly to new section seals to hold them in position during the gear
pump assembly.
3. After the pump has been assembled, tighten the bolts by hand. Rotate the
driveshaft to check for binding. Protect the shaft if you use pliers.
4. Torque the bolts evenly to 45 N∙m (33 ft-lb) in a crossing pattern.
