The Multiquip 30284 Spacer Instaclutch 3/4" Shaft is a genuine OEM component designed for Whiteman walk-behind power trowels including the JH55C, JH90C, and JS60C. Sourced directly from Multiquip, this spacer delivers the exact dimensional tolerancing required for correct clutch engagement on the Instaclutch 3/4" shaft assembly. Confirm your model code before ordering — this part is verified to fit the JH55C, JH90C, and JS60C trowel series.
Key Features
- Exact OEM Dimensional Tolerance — Manufactured to Multiquip's original specification, ensuring the spacer seats correctly on the 3/4" Instaclutch shaft without play or misalignment.
- Direct Clutch Shaft Compatibility — Designed to drop into the Instaclutch shaft assembly on the JH55C, JH90C, and JS60C with no rework to surrounding hardware.
- Confirmed Fitment for JH and JS Series Trowels — Verified for Whiteman walk-behind power trowel models JH55C, JH90C, and JS60C.
- Maintains Proper Clutch Engagement — Correct shaft spacing keeps the Instaclutch engaging and releasing cleanly; a worn or missing spacer can cause inconsistent clutch response and accelerated drivetrain wear.
- Genuine OEM Part — Supplied under Multiquip part number 30284, this is an original equipment component — not a generic substitute — giving you full confidence in fit and function.
The Instaclutch shaft spacer maintains the correct axial positioning of clutch components along the 3/4" drive shaft in Whiteman walk-behind power trowels. By holding the clutch assembly at the precise location on the shaft, the spacer ensures consistent engagement pressure and even load transfer to the trowel blades. When this spacer is worn, cracked, or missing, clutch slippage, uneven blade response, and premature wear to adjacent shaft components are common results.
