The Multiquip 28404968004 Friction Spring is a genuine OEM component designed for the BP-25H gasoline backpack flex-shaft vibrator. Sourced directly from Multiquip, this part matches the original specification installed at the factory, ensuring a correct fit without guesswork. If you're servicing a BP-25H unit, verifying you have the right friction spring is critical to restoring proper vibrator function and drive engagement.
Key Features
- Genuine OEM Spring Tension: — Manufactured to the exact tension rating of the original, so clutch engagement and drive transfer perform as the BP-25H was designed to deliver.
- Direct OEM Replacement: — Installs in place of the worn or broken factory spring with no machining or fitting adjustments needed.
- Confirmed Fitment: — Verified for the Multiquip BP-25H gasoline backpack flex-shaft vibrator series.
- Restores Drive Engagement: — A worn friction spring causes slipping or inconsistent clutch engagement in the flex-shaft drive; replacing it brings the unit back to full, consistent power transfer.
- Built for Demanding Jobsite Use: — Constructed from spring-grade material matched to the high-cycle demands of concrete vibration work, resisting fatigue and deformation over repeated use.
The friction spring in the BP-25H backpack vibrator plays a key role in the clutch and drive engagement system, maintaining the correct amount of tension to transfer power from the engine through the flex shaft to the vibrator head. When this spring weakens, stretches, or breaks, the drive can slip, engage erratically, or fail to transmit power altogether — resulting in reduced vibration output or a completely non-functional unit. Replacing a faulty friction spring is a straightforward service step that restores consistent, full-power operation to the backpack vibrator.
