Key Features

• Genuine OEM Construction — Manufactured to Multiquip's original material and dimensional specifications for the crankshaft flange interface, delivering the same structural integrity as the part it replaces.
• Direct Service Replacement — Designed as a bolt-on service component that aligns with existing crankshaft and drivetrain mounting points, simplifying the repair process in the field or shop.
• Broad Trowel and Roller Fitment — Compatible with HHNG5, HTXD6i, STXD6i, J36-M30 ride-on power trowels and RW1403HF roller models, covering multiple machines in the Multiquip lineup.
• Drivetrain Integrity — A correctly functioning crankshaft flange maintains proper rotational alignment between the engine output and blade or drive assemblies; a worn or damaged flange can cause vibration, misalignment, and accelerated wear on connected components.
• Authorized Distributor Supply — Sourced directly through DHS Equipment as an authorized Multiquip parts distributor, ensuring part authenticity and accurate part number verification for your service records.

The crankshaft flange is a critical power-transfer component that connects the engine's crankshaft output to the drivetrain or blade drive assembly on ride-on trowels and rollers. It serves as the mechanical interface that transmits rotational force while maintaining precise alignment between rotating components. When a crankshaft flange becomes worn, cracked, or damaged, it can introduce vibration, cause uneven blade or drum rotation, and place excessive stress on adjacent bearings and shaft seals — making timely replacement essential to keeping the machine operating safely and accurately.
