Internal rotating and reciprocating components for the GP5132 power end — bearings, bearing covers, shaft seals, shims, crankshaft, connecting rods, and crossheads. These are the parts a technician works through during a major power end overhaul or when diagnosing mechanical noise, shaft play, or vibration.

The three bearing shims (0.1 mm, 0.15 mm, 0.2 mm) are used together during taper roller bearing preload adjustment. When replacing the taper roller bearing, order all three shim sizes — the correct combination depends on measured endplay and cannot be determined until the bearing is seated.
