The Multiquip 0107090645 Impeller Bolt is a genuine OEM component designed for QP4TZT10P, QP4TZTMPXF, QP4TZ, and QP4TZTMP16F series trash pumps. As a direct OEM replacement, it is manufactured to the same specifications as the original hardware — ensuring a correct installation with no guesswork on fit or torque behavior. This bolt is a critical fastener that secures the impeller to the pump shaft, making it an essential part of any pump rebuild or impeller service. DHS Equipment stocks genuine Multiquip parts so you can get your pump back in service fast.
Key Features
- Genuine OEM Hardware Grade — Manufactured to the same thread pitch, shank diameter, and tensile strength as the original bolt, ensuring the impeller seats and locks correctly under pump operating loads.
- Direct Installation Fit — Threads directly into the impeller hub just like the original, with no modification to the pump shaft or impeller required.
- Confirmed Fitment — Compatible with QP4TZT10P, QP4TZTMPXF, QP4TZ, and QP4TZTMP16F Multiquip trash pump models.
- Maintains Impeller Retention Under Load — A correctly torqued impeller bolt keeps the impeller centered and locked on the shaft; a worn, stripped, or missing bolt allows impeller movement that causes vibration, cavitation, and accelerated volute wear.
- Essential for Pump Rebuilds — Replacing this bolt during any impeller service or pump rebuild ensures the fastener holding your rotating assembly is fresh, undamaged, and torqued to spec.
The impeller bolt is the primary fastener that clamps the impeller onto the pump shaft, transmitting rotational force from the engine to the pump's rotating assembly. Without a secure and properly torqued impeller bolt, the impeller can loosen during operation, causing loss of prime, reduced flow output, and serious internal damage to the pump housing and shaft. Replacing this bolt whenever the impeller is removed is considered standard practice to ensure safe and efficient pump performance.
