Multiquip 12725 Rocker Arm Frame Assembly 1" HHN - OEM Replacement Part

The rocker arm frame assembly is a critical component that supports and houses trowel arms in walk-behind power trowels, enabling the proper pitch adjustment and blade rotation required for smooth concrete finishing operations. This 1-inch HHN assembly connects the trowel arms to the spider plate and maintains the precise alignment necessary for uniform concrete surface treatment.

During trowel arm maintenance and adjustment procedures, this frame assembly works in conjunction with trowel arm adjustment tools (P/N 9177) to achieve the required .010-inch clearance specifications. The assembly must maintain precise tolerances as trowel arms are inspected with feeler gauges (.004 inch for hex sections, .005 inch for round shafts) to ensure straightness. Bent or damaged rocker assemblies can prevent blades from rotating smoothly and result in poor concrete finishing quality. Common damage occurs from rough handling, dropping the trowel on pads, or striking exposed plumbing, forms, or rebar during operation.

Compatible with the following Multiquip power trowel models:

• EHHNK5
• HHN-34TVD
