The Multiquip 31110ZM7004 Flywheel is a genuine OEM component designed for the BP-25H gasoline backpack flex-shaft vibrator. Sourced directly from Multiquip, this flywheel matches the original part specification to ensure correct fit and function within the engine assembly. If you are servicing a BP-25H unit, verifying part number 31110ZM7004 against your machine's serial plate is the surest way to confirm compatibility before ordering.
Key Features
- Genuine OEM Specification: — Cast and balanced to the same dimensional tolerances as the original flywheel, ensuring proper rotational mass and ignition timing alignment within the engine.
- Direct Engine Drop-In: — Engineered to mount directly onto the crankshaft of the BP-25H engine, matching original keyway position, taper fit, and fastener pattern without modification.
- Confirmed BP-25H Fitment: — Validated for use on the Multiquip BP-25H gasoline backpack flex-shaft vibrator; always cross-reference part number 31110ZM7004 with your unit's documentation.
- Consistent Engine Power Delivery: — A correctly weighted and balanced flywheel maintains steady crankshaft rotation, which directly supports smooth power transfer to the flex shaft and vibrator head during concrete consolidation.
- Ignition System Integrity: — The flywheel carries the magneto magnets that trigger the ignition coil; a worn or damaged flywheel can cause weak spark, hard starting, or misfires — replacing it restores reliable ignition output.
The flywheel is a heavy rotating disc mounted on the engine crankshaft that stores rotational energy to smooth out the power strokes of the engine and keep it running evenly between combustion cycles. On a backpack vibrator like the BP-25H, it also houses the permanent magnets that pass by the ignition coil to generate the spark needed to fire the engine. When a flywheel becomes cracked, loses a magnet, or develops key-way wear, the engine may run roughly, lose power, or fail to start altogether — making timely replacement critical to keeping the vibrator operational on the pour.
