Multiquip 21746 Spring 0.42 OD x 2.5L

The Multiquip 21746 Spring 0.42 OD x 2.5L is a genuine OEM component designed for Whiteman walk-behind power trowels across a wide range of models, including the HDA-Series, B46, J36-M30 Series, CA4HM, BS90C, BH11C, BH90C, J3036H55, JS60C, JH90C, and JH55C. As a direct OEM replacement, part 21746 is manufactured to the same specification as the original, ensuring correct tension, travel, and engagement characteristics right out of the box. Sourced directly through authorized Multiquip distribution channels, this spring is the correct choice when restoring your trowel to full operating condition. DHS Equipment stocks genuine Multiquip parts so you can confirm fitment by model code and order with confidence.

Key Features

• Correct Spring Geometry — Manufactured to 0.42 OD x 2.5L specification, matching the original compression and return force required by the trowel mechanism.
• Genuine OEM Part — Sourced through authorized Multiquip channels; this is the same spring supplied in new Whiteman walk-behind trowels at the factory.
• Broad Model Coverage — Confirmed fitment across HDA-Series, B46, J36-M30, CA4HM, BS90C, BH11C, BH90C, J3036H55, JS60C, JH90C, and JH55C trowels.
• Drop-In Installation — Designed to seat and engage exactly as the original, with no modification to mounting points or adjoining components needed.
• Consistent Blade Response — A correctly tensioned spring maintains proper clutch or pitch-adjustment engagement, so the trowel blades respond accurately to operator input on every pass.

Springs in walk-behind power trowels serve a critical role in maintaining tension and return force within the clutch, blade-pitch, or throttle linkage assemblies — depending on their location in the machine. When a spring loses its set, stretches, or breaks, the affected mechanism may become sluggish, fail to return to its neutral position, or disengage unpredictably, leading to uneven finishing results and potential wear on surrounding components. Replacing a fatigued or damaged spring with the correct OEM part restores the precise mechanical response the trowel was designed to deliver.
