The Multiquip EM40121 Assembly CVT Upper Mod Flyweight Orange is a genuine OEM component designed for the EHHNK5 series international ride-on power trowels. This is a direct OEM replacement sourced from Multiquip, ensuring the part matches the original design specifications for the CVT (continuously variable transmission) system on your machine. Verified fitment for the EHHNK5 makes this the correct choice when servicing or rebuilding the upper CVT flyweight assembly.

Key Features

  • Genuine OEM CVT Component — Manufactured to the same tolerances and material specifications as the original flyweight, ensuring the CVT engages and shifts at the correct rpm range.
  • Orange Flyweight Designation — The orange color coding identifies a specific weight and engagement profile; using the correct-rated flyweight is critical to maintaining proper CVT behavior and avoiding under- or over-engagement.
  • Direct Replacement for EHHNK5 — Engineered specifically for the EHHNK5 international ride-on power trowel CVT upper module, dropping into the existing assembly without alteration.
  • Preserves Blade Speed Consistency — A correctly weighted flyweight keeps blade rotation speed stable across varying load conditions, directly affecting finish quality on the concrete surface.
  • Authorized Multiquip Part — Sold by DHS Equipment as an authorized Multiquip OEM part, backed by verifiable part number EM40121 for accurate ordering and service records.

The CVT (continuously variable transmission) flyweight assembly plays a central role in how a ride-on power trowel modulates engine power to the finishing blades. The upper flyweight — color-coded orange to indicate its specific engagement weight — works within the CVT pulley system to determine at what engine speed drive force is transferred to the blades. If the flyweight is worn, cracked, or the wrong rating, the CVT will engage erratically, slip under load, or fail to transfer power efficiently, resulting in inconsistent blade speed and poor surface finish. Replacing it with the correct EM40121 assembly restores smooth, predictable CVT operation.
