The Multiquip 14478 Coupling Shaft Pulley is a genuine OEM component designed for BPX series backpack flex-shaft concrete vibrators. As a direct OEM replacement sourced from Multiquip, part 14478 is built to the same specifications as the original, ensuring a correct fit within the drive assembly of BPX vibrators. DHS Equipment stocks this part to help contractors keep their concrete consolidation equipment running at full capacity without guesswork on compatibility.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original design tolerances, ensuring the pulley engages the shaft coupling with the correct geometry and load-bearing capacity expected of the BPX drive system.
- Direct Drop-In Replacement — Mounts in the same position as the factory pulley with no reworking of surrounding components required, making field or shop replacement straightforward.
- BPX Series Compatibility — Confirmed fitment for BPX backpack flex-shaft vibrators, so you can order with confidence knowing this pulley is matched to your machine.
- Drive Power Transfer — A correctly functioning shaft pulley maintains consistent rotational force transfer from the engine to the flex shaft, which directly affects vibration output and concrete consolidation quality.
- Sourced from Multiquip — Genuine OEM designation means this part carries the same part number — 14478 — used by Multiquip's own service network, so there is no ambiguity about what you are receiving.
The coupling shaft pulley is a core component in the BPX backpack vibrator's drive train. It transfers rotational power from the engine to the flex shaft, which in turn drives the vibrator head immersed in fresh concrete. When this pulley wears, cracks, or becomes misaligned, the flex shaft loses consistent drive input — resulting in reduced vibration frequency, poor concrete consolidation, and potential void formation within the pour. Replacing a worn pulley with a correct OEM part like the Multiquip 14478 restores full drive engagement and keeps the vibrator performing as intended.
