Multiquip 22891 Clutch 1.0" Adjustable Sheave

The Multiquip 22891 Clutch 1.0" Adjustable Sheave is a genuine OEM component designed for Whiteman walk-behind power trowel models JS60C, JH90C, JH55C, BS90C, BH11C, and BH90C. As a direct OEM replacement, this sheave meets the exact dimensional and material specifications of the original part, ensuring the drive system engages and disengages with the same responsiveness as when the trowel left the factory. Sourced directly from Multiquip, part 22891 is the correct-spec choice for operators who need a dependable, like-for-like repair on their finishing equipment.

Key Features

• OEM-Grade Sheave Material — Manufactured to the same hardness and groove tolerances as the original, ensuring consistent belt contact and wear life under continuous troweling loads.
• Adjustable 1.0" Drive Configuration — The adjustable sheave design allows precise belt tension tuning during installation, helping maintain optimal blade speed across varying concrete conditions.
• Confirmed Fitment for Whiteman Walk-Behind Trowels — Verified for JS60C, JH90C, JH55C, BS90C, BH11C, and BH90C models; bolts directly into the existing clutch assembly without modification.
• Protects Clutch Engagement Consistency — A worn or out-of-spec sheave causes belt slippage and uneven blade rotation; replacing with 22891 restores smooth, consistent clutch engagement.
• Genuine Multiquip OEM Part — Supplied by an authorized Multiquip dealer, this is the same part installed at the assembly level — not a substitute or approximation.

The adjustable sheave is a critical component in the clutch drive system of a walk-behind power trowel. It works by gripping and guiding the drive belt that transfers power from the engine to the trowel blade assembly, with the adjustable design allowing belt tension to be dialed in for proper slip-free engagement. When the sheave wears, becomes grooved, or loses its dimensional integrity, the belt begins to slip under load — causing inconsistent blade speed, excessive heat buildup, and accelerated wear on surrounding drivetrain components. Replacing the sheave promptly with the correct OEM part restores full power transfer and keeps the trowel finishing concrete evenly and efficiently.
