Replacement components for the GP5132 power end — the crankcase housing, covers, oil management hardware, and drip tray. These are the structural and enclosure parts of the pump's drive section: the parts you work through when repairing external damage, addressing an oil leak at the housing, or replacing worn hardware without opening the drive train.

The crankcase and crankcase cover are the two major castings. Everything else in this group is low-cost hardware — drain plugs, gaskets, O-rings, screws — available individually so a minor repair doesn't require sourcing the full assembly.

For parts related to the bearings, crankshaft, or connecting rods inside the power end, see GP5132 Bearing & Drive Train Parts.
