The Multiquip 0105090840 is a genuine OEM Bolt (Engine) M8 X40 designed for QP2TB, QP2TH, and QP3TB series pump equipment. As a factory-sourced fastener, it meets the exact thread pitch, grade, and dimensional specification required for secure engine mounting on these units. This bolt is a direct OEM replacement, ensuring the correct torque retention and structural integrity that the original design demands. Confirm your model code against the QP2TB, QP2TH, or QP3TB fitment list before ordering to ensure an exact match.
Key Features
- OEM-Grade Fastener Specification — Manufactured to the exact M8 x 40 thread class and tensile grade specified for engine mounting, ensuring correct clamp load and resistance to vibration-induced loosening.
- Drop-In Engine Mount Replacement — Threaded to factory dimensions, this bolt seats directly into existing engine mounting points with no rethreading or modification to mating hardware.
- Confirmed Fitment for QP Series Pumps — Verified for use on QP2TB centrifugal pumps, QP2TH trash pumps, and QP3TB centrifugal pumps.
- Maintains Engine Alignment Under Load — A correctly torqued engine mount bolt keeps the engine seated true to the pump frame, preventing misalignment that can accelerate wear on the impeller shaft and couplings.
- Critical Safety Fastener — Engine mount bolts are structural fasteners; using the correct grade and length is essential to prevent engine movement that could damage fuel or exhaust connections under operating load.
Engine mounting bolts secure the power unit to the pump frame, maintaining precise alignment between the engine output shaft and the pump drive components. A loose or incorrect fastener allows micro-movement under vibration, which accelerates wear on shaft seals, couplings, and the pump housing itself. Replacing a worn or missing mount bolt with the correct OEM specification — in this case M8 x 40 — restores the rigid, vibration-resistant connection the engine assembly requires to operate safely and efficiently.
