The Multiquip EM20350 Spacer Rocker Arm 3 is a genuine OEM component designed for HHN31V and HHXG5 Whiteman ride-on power trowels. As a factory-authorized part, EM20350 is manufactured to the exact tolerances required for correct rocker arm positioning and blade pitch control in these machines. Sourcing a genuine OEM spacer ensures the rocker arm assembly operates as intended, maintaining consistent finishing performance across the full blade pitch range. DHS Equipment stocks this part to support operators and dealers who demand accurate, fit-verified replacements.
Key Features
- Genuine OEM Tolerancing — Manufactured to the exact dimensional spec required for proper rocker arm alignment, ensuring the spacer seats correctly within the blade pitch assembly without binding or play.
- Direct-Fit Replacement — Replaces the original EM20350 spacer on a one-to-one basis, integrating into the rocker arm linkage with no rework or machining needed.
- Confirmed Fitment — Verified for HHN31V and HHXG5 Whiteman ride-on power trowels, so you can order with confidence that this is the correct part for your machine.
- Blade Pitch Accuracy — A correctly dimensioned rocker arm spacer maintains precise blade angle control, which is critical for achieving a flat, consistent surface finish on large concrete slabs.
- Prevents Premature Wear — An incorrect or worn spacer introduces unwanted play into the rocker arm linkage, causing uneven blade loading and accelerated wear across connected components.
The rocker arm spacer is a small but critical component within the blade pitch control linkage of a ride-on power trowel. It maintains the correct positional relationship between rocker arm pivot points, ensuring that blade angle adjustments translate accurately and evenly across all blades. When this spacer is worn, damaged, or dimensionally incorrect, the rocker arm assembly develops slop that results in inconsistent blade pitch, uneven troweling pressure, and a compromised surface finish.
