The Multiquip 48187 Engine Briggs & Stratton XR1450 9HP is a genuine OEM power unit designed for B46 series walk-behind power trowels. Sourced directly from Multiquip, this is the same engine that ships on production machines — ensuring a correct, confidence-inspiring installation. If your B46 trowel has lost power, runs rough, or requires a complete engine replacement, part 48187 is the factory-specified solution. DHS Equipment stocks genuine Multiquip OEM parts so you can get your trowel back to work without compromise.
Key Features
- Genuine OEM Engine Assembly — The Briggs & Stratton XR1450 9HP is the factory-specified engine for this application, meaning output torque, mounting configuration, and throttle linkage all match original build standards.
- Direct-Mount Replacement — Engineered to bolt into the B46 trowel frame using the original mounting points, keeping installation straightforward for experienced technicians.
- Confirmed B46 Fitment — Verified compatibility with Multiquip B46 series walk-behind power trowels; always cross-reference your model and serial number before ordering.
- Full 9HP Output — Restores the rated power delivery the B46 trowel relies on to maintain consistent blade speed and finishing quality across a full concrete slab.
- Briggs & Stratton XR1450 Platform — Built on a proven commercial small-engine architecture with wide parts availability and established service support in the field.
The engine is the core power source of a walk-behind power trowel, converting fuel into the rotational force that drives the gearbox and spinning trowel blades. On the B46, the Briggs & Stratton XR1450 9HP delivers the torque needed to keep blades rotating consistently under the load of wet or stiffening concrete. When an engine loses compression, fails to start, or produces insufficient power, blade speed drops and finishing quality suffers — a complete engine replacement with the correct OEM unit like 48187 restores full operating capability and keeps the trowel performing as intended.
