Key Features
- Genuine OEM Crankshaft Integrity — Factory-manufactured to the original stroke geometry and material specification, maintaining correct reciprocating motion within the pump assembly.
- Direct Drop-In Fit for QP-40TE — Engineered specifically for the QP-40TE trash pump, this crankshaft installs to the original mounting configuration without modification.
- Confirmed QP-40TE Compatibility — Fitment verified for the Multiquip QP-40TE series; always cross-reference your model code before ordering.
- Sustained Pump Output — A correctly functioning crankshaft converts engine rotation into consistent piston stroke, maintaining rated flow and pressure. A worn or damaged crankshaft leads to loss of prime, reduced output, and accelerated wear on surrounding components.
- Critical Drivetrain Component — As a core mechanical link between the engine and pump end, crankshaft condition directly affects operational safety; replace at first sign of wear, scoring, or out-of-round bearing journals.
The crankshaft in a reciprocating trash pump is the central rotating component that transforms the engine's rotary power into the back-and-forth piston motion needed to draw in and expel fluid. It works in close tolerance with the connecting rod, bearings, and pump housing — any wear or damage disrupts stroke consistency and reduces pumping efficiency. A failed crankshaft can cause complete loss of pump function and, if left unaddressed, may damage the engine-side components as well.
