Connecting rods and caps are matched sets and must always be
reassembled with their original mate and in the same orientation.
Reference the numbered codes stamped on each half of the connecting
rod assemblies and make certain they are installed as matched set and in
the same orientation when re-assembling the pump.
6. Inspect the crankshaft journals and other internal parts for damage.
7. Clean all parts before assembly and clean the sump area of the power frame.
8. Reinstall or replace shell bearings (4) in the connecting rod and connecting rod
caps. Ensure that rod caps are properly assembled with their mating connecting
rod. Torque the fasteners holding the end caps to the mating rod per the values
given in Table 7: Torque Values for Critical Pump Fasteners. Use back and forth
pattern from one fastener to the other tightening with a torque wrench. After the
cap screws are torqued, a light strike to the cap with a rubber hammer will help
properly seat the rod bearings.
9. Inspect the back cover gasket (15) and replace if damaged. Install back cover
gasket and back cover (14). Torque the back cover fasteners (17) per the values
given in Table 7: Torque Values for Critical Pump Fasteners.
10. Reinstall the seal housings (19) per section 10.4.1 instructions.
11. After reassembly be sure to fill the pump power end with the proper amount of
lubricating oil. Refer to the start-up check list before restarting your pump.
