Multiquip 9148 Wear Ring Extension Arm Assembly (Heavy Duty) - OEM Replacement Part

The wear ring extension arm assembly is a critical component that connects the trowel blade to the gearbox drive shaft on walk-behind power trowels. This heavy-duty assembly withstands constant rotational forces and ground contact during concrete finishing operations. Worn or damaged extension arms cause uneven blade wear patterns, poor finish quality, and potential machine damage.

Regular inspection of trowel arms is essential per Multiquip maintenance protocols. Replace immediately if arms are bent, damaged, or causing uneven blade wear. Bent trowel arms can result from rough handling, dropping the machine, or striking exposed plumbing or rebar during operation. Damaged arms prevent smooth blade rotation and create perceptible rolling or bouncing motion during use. The hexagonal shaft section interfaces with the gearbox drive, while the round shaft section holds the blade attachment hardware and incorporates mounting slots for the pitch adjustment lever.

Compatible with the following Multiquip trowel models:

• HDA-SERIES
• HHNG4
• HHXDF4
• HRT
• HTX-44K4
